How much water evaporates from an indoor pool in a year?

An indoor pool will evaporate the full volume of the pool in a year. You can calculate the evaporation of a pool, convert it to gallons and compare it to the volume of water in the pool.

What is a dehumidifier?

A refrigerative dehumidifier operates by drawing air over the evaporator coil, which transfers heat energy from the air to the refrigerant within the evaporator. As the heat energy is removed from the air, the moisture in the air condenses and the water drains into the condensate pan and down the drain. The cool, dry air passes through the reheat coil condenser and reabsorbs the heat energy from the hot gas refrigerant. The warm, dry air is discharged into the space. Heat energy can also be transferred to alternate refrigerant condensers to provide space cooling or water heating as specified.

What is a good energy conscious temperature set point range of my regular use residential indoor pool?

The rule of thumb is to maintain the air temperature 2°F above the water temperature, with an upper limit of 86°F air temperature.

The recommended temperature for a residential pool set point ranges from 78°F to 86°F.

What is the ph of dehumidifier condensate water?

Ph of dehumidifier condensate water is 7. It’s neutral on the ph scale.

The benefits of harvesting condensate water.

What is Vapor Pressure Deficit and why should I care about it?

Vapor Pressure Deficit (VPD) is the difference (deficit) between the amount of moisture in the air and how much moisture the air can hold when it is saturated. VPD can help an indoor grower identify healthy air moisture conditions over the full range of growing temperatures. Vapor pressure deficit correlates directly to plant transpiration rates. Using VPD to fine tune water flow through plants gives the grower another “control knob” in the quest to balance the plant environment to create a perfect day year round.

Learn more about Vapor Pressure Deficit (VPD) and how it works in relation to our GrowAire dehumidification systems in our Blog: GrowAire™ VPDsync™ Masters 4 Elements of CEA Control and our video "Desert Aire GrowAire VPDsync Environmental Control".

What is condensation?

Condensation occurs when moist air passes over a cold surface and the water condenses from the air at a dew point temperature. A dehumidifier mechanically condenses a portion of the moisture in the air on cold coils within it, like a cold beer can getting wet from condensation. Learn more about  condensation, evaporation and dew point in our blog How 3 Key Dehumidification Terms Relate.

What is dew point?

The atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form. When moist air passes over a cold surface and the water condenses when it reaches its dew point temperature at the cold surface. Air can only hold so much moisture, as a function of the air temperature. Colder air can’t hold as much water vapor which condenses into water droplets at the dew point, the point that the air is saturated at 100% relative humidity. To learn more about dew point, view our blog How 3 Key Dehumidification Terms Relate.

What is evaporation?

Evaporation is simply the process of conversion of liquid water into vapor. Evaporation is a continuous process that occurs constantly outdoors in the lakes and ponds and is the reason why it rains. Evaporation is caused by the absorbance of heat from a source that will allow the conversion from a liquid to a vapor escaping a body of water.As pool water evaporates, it cools the pool water and the air in the pool room. Learn more about evaporation, condensation and dew point in our blog How 3 Key Dehumidification Terms Relate.

What is evapotranspiration?

Evapotransoration is the process by which water is transferred from plants to the atmosphere by evaporation from the plant's surfaces (usually leaves) and by transpiration from plants. It is the amount of “sweat” the plant produces that is evaporated into the air. This moisture is the real moisture load in an indoor grow room operation as it relates to the HVAC and dehumidification system. 

Why is dehumidification important to a swimming pool?

Swimming pool water evaporates into pool room air. This evaporation is moisture that condenses on any surface including windows that is at or below the dew point temperature in the pool room. This condensation can lead to deterioration of the surfaces, furnishings and the building itself, and create musty odors and mold growth.

In a cannabis indoor grow room application, what is the difference between "harvest at once" and "perpetual harvest"?

In a cannabis indoor grow room application, the difference between "harvest at once" and "perpetual harvest" is as follows:

Harvest at once: plants are brought into a grow room space where they stay as they grow from young plants through the flowering process and then are harvested. Then the room is cleaned and prepped for a new batch of young plants to be brought into the room to grow until flowering stage.

Perpetual harvest: plants are moved in and out of one grow room space to another grow room as the plants grow and will not stay in the same grow room during their full period of all stages of growth. 

In an indoor grow application how does a dehumidifier know if and when the lights go out?

A dehumidifier in an indoor grow application knows if and when the lights go out using a photocell wired to the dehumidifier's control system.

How does a pool dehumidifier work?

A refrigeration based pool dehumidifier operates by drawing air over an evaporator coil, which transfers heat energy from the air to the refrigerant within the evaporator. As the heat energy is removed from the air, the moisture in the air condenses into water that drains into a condensate pan and down a drain. The cool, dry air passes through the reheat coil condenser and reabsorbs the heat energy from the hot gas refrigerant. The warm, dry air is discharged into the space. Heat energy can also be transferred to alternate refrigerant condensers to provide space cooling or pool water heating as specified. For swmming pool dehumidifier sizing see Application Note 10: Swimming Pool Dehumidifier Sizing for swimming pool load calculations.

How do you size a dehumidifier for an indoor pool?

To size a dehumidifier for an indoor pool you can get assistance from Desert Aire Representatives that are trained to help you select the appropriate dehumidifier for your application.

Answers to the following questions are needed at a minimum to properly determine the best Desert Aire solution for your poolroom application:
1. What is the surface area of each pool or whirlpool within the poolroom?
2. What is the square footage of the poolroom?
3. What is the average ceiling height of the poolroom?
4. What is the temperature at which each pool will be maintained?
5. What is the temperature at which the poolroom will be maintained?
6. Is there a separate spectator area as part of a larger space?

In addition, see our Technical Application Note #10 about Indoor Pool Dehumidifier Sizing.  

How do you size an industrial dehumidifier?

Sizing an industrial dehumidifier involves establishing the project design conditions by answering questions and considering several factors: what is the best temperature and humidity for the application? After the design dry bulb temperature and humidity level has been established, check what the dew point is of these two conditions. What is the moisture load? After the worst case load is calculated the equipment is selected based on 100% of the calculated load or less. Other considerations include the size of the space, amount of outside air introduced, lowest temperature, existence of a vapor barrier and open liquid tanks. Desert Aire has developed a sizing tool that will calculate the moisture load of many industrial applications. The method used is based on the ACCA Manual N and ASHRAE formulas. Our Tech Bulletin 29 explains the information required and considerations for sizing an industrial dehumidifier. 

What refrigerants are used in Desert Aire dehumidification systems?

Desert Aire dehumidification systems use either R-410A or R-407C.

What is HFC Phasedown?

The Kigali Amendment to the Montreal Protocol establishes a global structure for the phasedown of hydrofluorocarbons (HFCs). Under the amendment, countries committed to cut the production and consumption of HFCs by more than 80 percent over the next 25 years. The phasedown puts a maximum cap on the production of new, virgin refrigerant, so the only way to keep old machines operational will be to reclaim the old refrigerant. 

For more information about the HFC Phasedown, read our blog HFC Phasedown. New Refrigerants Coming.

Are your dehumidifiers EnergyStar Rated?

Desert Aire dehumidifiers are not EnergyStar rated since the EnergyStar program does not cover the systems we build. The current EnergyStar program for dehumidifiers is limited to the free standing portable type (non-ducted) with compressor sizes less than 12,000 Btu/hr or less than 2 lb/hr of moisture removal. This program was an offshoot of the AHAM rating program for home appliances.

The EnergyStar program has not provided a rating system as of yet for the large systems that require more fan motor horsepower to overcome the static of supply and return air duct work. AHRI has created two standards to rate the moisture removal efficiency of larger dehumidifiers and Dedicated Outdoor Air Systems: AHRI 910 and 920 respectively are available from the ahrinet.org website.

How does switching from HID lighting to LED lighting in a grow room affect the HVAC system?

The switch from HID to LED is the most common change. The biggest difference between HID and LED is the LED lighting produces significantly less radiant heat. Comparing the leaf temperature of a room with HID and LED lights shows the room with HID lights has leaf temperatures of 3-4 degrees F higher than the room temperature. The room with LED lighting will have leaf temperatures of 2-3 degrees lower than the room temperature. The reduction in leaf temperatures with LED lighting allows growers to raise the room temperature slightly.

 

The reduction in radiant heat in grow rooms with LED lighting results in the ability to raise the room temperature slightly.  The benefit of this is the DX system’s latent moisture removal capacity while reducing the sensible cooling in the room. One of the key factors in a lighting change is the corresponding change in temperature and humidity set points. The performance of HVACD systems is greatly impacted by the lighting choice and set points. Always review every room condition calculation when making a change in plant count, lighting, watering or anything in a cultivation room and determine how it affects the HVACD system, its capacity, settings, and performance.

What is a chilled water dehumidification system?

Chilled water dehumidification uses cold water from a chiller generally below 42F° (16°C) as the fluid to remove moisture from an airstream.  As the air is cooled below saturation, water is condensed out of the air.  The colder the water the more moisture can be removed. Learn more about GreenAire™.

When or why would I specify a chilled water dehumidification system?

One advantage of a chilled water system is it is generally easier to plumb water piping than it is refrigerant piping. Recovered energy can be easily be reused in all parts of a facility. Chillers have a better energy efficiency.

One disadvantage is the chiller/air handler system will be more expensive than a D/X refrigeration based system. Learn more about GreenAire™.

What is the difference between a D/X dehumidification system and other types of dehumidification system?

Most dehumidifiers use a refrigerant direct expansion (D/X) technology that the airstream flows across. The refrigerant makes the evaporator coil very cold and then condenses water from the air moving over it.  This technology is used for 45% to 65% relative humidity targets. 

Desiccant wheel systems use a specialty absorption type of wheel to remove humidity in applications requiring low humidity ranges below 40% RH.  After the water is absorbed by the wheel it rotates to second air stream that uses heat to remove the water.

What size grow canopy and HVAC load can a chilled water air handling system be used with?

In concept, a chilled water system can be used in any size facility.  However, the cost to install and maintain for small facilities is not normally practical.

In general, facilities larger than 100,000 square feet with demands greater than 200 to 300-ton cooling load or larger will consider chilled water systems. Learn more about GreenAire™.

Can a natural gas chiller be used with GreenAire?

Natural gas chillers provide both the chilled water and hot water necessary for the GreenAire to function. These types of chillers also help reduce the electrical connect load for the facility. Learn more about GreenAire™.

What kind of chillers can be used with a GreenAire system?

Desert Aire’s GreenAire system can use any type of chiller that produces water below 42°F (16°C) and heat recovery chillers, absorption chillers and natural gas chillers. Learn more about GreenAire™.

What is a heat recovery chiller?

A heat recovery chiller uses the internal refrigerant to capture some or all of the waste heat and use it to heat a second water loop up to 100°F to 120°F (37°C to 49°C) for use by the GreenAire™ system.

While it is important for a design engineer to calculate the exact hot water load, a general rule of thumb is only 50% of the chiller must be used for heat recovery, lower its cost. 

Can a redundant chiller design be incorporated into a GreenAire system?

It is highly recommended to use a minimum of two or three chillers for the facility providing redundancy. These chillers can be plumbed together to be used for the entire facility. A design subset of chillers are modular chillers which can be sized to provide many layers of redundancy. Learn more about GreenAire™.

Why do I need a dehumidifier for my poolroom?

Pool water evaporates into poolroom air. This evaporation is moisture that condenses on any surface including windows that is at or below the dewpoint temperature in the poolroom. This condensation can lead to deterioration of the furnishings and the building itself, musty odors and mold growth.

Why can't I just use outdoor air to remove moisture from a poolroom?

Using only outdoor air for your poolroom ventilation can be expensive and makes it difficult to control a poolroom's humidity level, and the rate of evaporation from the pool surface. In some areas, outdoor air will often contain more moisture than the air inside the poolroom. Introducing humid outdoor air only increases the moisture content of the air inside the poolroom where it condenses on surfaces that are cooler than the dewpoint temperature. This condensation can lead to deterioration of the furnishings and the building itself while causing odors and promoting mold growth.

Conversely, introducing outdoor air that is too dry into a poolroom can accelerate evaporation of the pool water. In addition to the expense of adding water and water treatment chemicals to the pool, the accelerated evaporation makes swimmers feel chilled when their skin quickly dries upon leaving the water. Desert Aire dehumidification systems provide optimum control of humidity in your poolroom environment to safeguard the comfort and health of building users; protect furnishings and building systems; and conserve energy, water and water treatment resources.

Which Desert Aire dehumidification system should I choose for my poolroom application?

Several Desert Aire dehumidification systems are available for poolroom applications. For help in sizing and choosing the system that is best for your needs, please contact a Desert Aire Representative. To find your local representative, please use the Find A Rep function in the Contact submenu of this website.

What dehumidification system is best for large indoor pools, aquatic centers and natatoriums?

Desert Aire's SelectAire and SelectAire Plus dehumidification systems are specified for large indoor pools, aquatic centers and natatoriums. Desert Aire SelectAire (SA) Series systems are flexible in their design options and can be customized for specific applications. For example, SA Series systems can be installed indoors or outdoors; equipped with or without energy recovery systems; and equipped with or without outdoor air box systems for ventilation air.  

Desert Aire SelectAire Plus (SP) series can be applied to the same types of installations but has enhanced features for energy efficiency and control.  In addition to the unique heat-pump type energy recovery of all SelectAire systems, the SP series has double-wall foam-injected casing, self-balancing direct-drive plenum fan arrays for both supply and exhaust, and a wrap-around heat-pipe for enhanced moisture removal efficiency among many other enhanced features.

What information is needed to size a poolroom dehumidifier?

Desert Aire Representatives are trained to help you select the appropriate dehumidifier for your application. Answers to the following questions are needed at a minimum to properly determine the best Desert Aire solution for your poolroom application:
What is the surface area of each pool or whirlpool within the poolroom?
What is the square footage of the poolroom?
What is the average ceiling height of the poolroom?
What is the temperature at which each pool will be maintained?
What is the temperature at which the poolroom will be maintained?
Is there a separate spectator area as part of a larger space?

At what temperature should a poolroom be maintained?

As a general rule, the temperature should be maintained at about 2° F above the water temperature. It is Desert Aire's recommendation that the air temperature should not be above 86° F.

At what relative humidity level should a poolroom be maintained?

It is recommended that the relative humidity be maintained at between 50% and 60% in the poolroom.

Why should I use an outdoor air box on a poolroom dehumidifier?

Outdoor air is introduced into a dehumidification system after the evaporator coil for several reasons. During the winter cold outdoor air may cause condensation in return air at undesirable places in the system or ductwork. Also, the variability of the outdoor air will influence the design and performance of the evaporator coil. When colder outdoor air mixes with the return air from a poolroom, it lowers the mixed air conditions that flow over the evaporator coil. This lower condition reduces the capacity of the system and creates a variable, unpredictable moisture removal and cooling capacity. To eliminate these issues, Desert Aire’s outdoor air box introduces the outdoor air between the evaporator and hot gas reheat coil.

Where are ExpertAire Series dehumidifiers used?

ExpertAire Series dehumidifiers are used wherever excess humidity is a problem. Common applications include residential and hotel poolrooms, water treatment and wastewater treatment plants, records storage areas, warehouses and manufacturing facilities.

In what temperature conditions can an ExpertAire Series dehumidifier be used?

ExpertAire dehumidifiers are designed to operate in air temperatures between 65° and 95° F (18° to 35° C).

How much moisture can an ExpertAire dehumidifier remove?

ExpertAire Series dehumidifiers are available in a range of sizes designed to remove between 8 lbs/hour and 84 lbs/hour of moisture from the air at ARI standard 82° F / 60% RH. Your Desert Aire Representative is available to assist you with unit selection for your application.

Does the ExpertAire Series meet AHRI 910?

Yes. ExpertAire Series dehumidifiers are compliant with AHRI's moisture removal efficiency (MRE) requirement for indoor pool applications.

Can the ExpertAire Series dehumidifier introduce outdoor air?

Yes. The ExpertAire Series dehumidifiers are available with an outdoor air intake option.

What is a DOAS?

DOAS is a dedicated outdoor air system. DOAS are used to introduce outside air into a space as specified by the mechanical design engineer. In many areas local building codes require that outdoor air be brought into the building to help improve indoor air quality for occupants.

Unfortunately, outdoor air can also introduce moisture into a facility and can create IAQ problems such as mold, mildew and an environment where viruses and other organisms can flourish. The key to preventing mold formation and IAQ problems is to control the humidity level inside the building. While a standard air conditioner is thermostat controlled to provide space cooling, it cannot accurately control the humidity levels.

Desert Aire's answers to this problem are our Aura™, VerticalAire™ and TotalAire™ systems, which are designed to introduce 100% outdoor air while precisely controlling space humidity and temperature levels.

Please contact your local Desert Aire Representative for help in selecting the Aura™, VerticalAire or TotalAire DOAS system that is best for your application.

Do Desert Aire's DOAS solutions meet AHRI 920 and ASHRAE 90.1 energy minimums?

Yes. All of Desert Aire DOAS solutions comply with AHRI's moisture removal efficiency (MRE) requirements and significantly exceed ASHRAE 90.1 2013 minimum energy efficiency ratings.

Where are SP Series dehumidifiers installed?

The SP Series units were designed to be an extremely high efficiency climate control unit tailored to large indoor pool facilities such as natatoriums or waterparks.  Other applications where high levels of dehumidification are possible if target air conditions are similar.

What makes a SelectAire Plus (SP) different from a SelectAire (SA) unit?

The SelectAire Plus design leverages the additional 25 years of innovation in design and manufacturing capabilities to increase the energy efficiency, ease of use, and environmental control.  The SP has an alternate airflow and coil arrangement to continue to provide the extremely effective energy recovery of the SelectAire system while eliminating the possibility of bypass air from the outdoor to the exhaust.  The SP also includes a wrap-around heat pipe to increase dehumidification capacity and efficiency.  

The combination of the SelectAire energy recovery and the enhanced dehumidification of the SelectAire Plus (SP) is a patent pending design. 

How does the SP increase the energy efficiency?

The SP Series unit contains two refrigeration circuits.  One is optimized for dehumidification, the other is optimized for heat recovery and cooling.  The control logic in the machine senses the space requirements and shifts the operation of each circuit and the airflow in the machine to use the most efficient methods to condition the space. 

Direct drive fan arrays, scroll compressors, and heat exchangers that use the refrigerant directly to exchange energy with the air are also important to reducing energy use.  

What refrigerant do SP dehumidifiers use?

R-410A refrigerant

How does the SelectAire Plus system compare to a system that uses both refrigerant and water/glycol for cooling or heating?

Some equipment manufacturers divert the refrigerant gas to and air-to-water heat exchanger then move that water to another water to air heat exchanger to condition the air.  Although it may be easier to design a system this way, it is much less efficient.  The compressor needs to work harder since it is more difficult to transfer the energy.  There are also additional pumps, valves, control, and heat exchangers to fail.  The SelectAire Plus is designed to directly exchange the energy from the refrigerant heat exchangers to the air.  This reduces complexity and increases energy efficiency.  

What makes the SP unit so easy to install?

Dampers and fans are self-balancing and are factory programmed for the flow rates at the time of order.  Commissioning consists of reviewing the flow rates programmed on the units display terminal and ensuring that the field-installed ductwork allows the airflow programmed.  

SP Series units are available in packaged air-cooled models up to the SP80 model size. This is an industry exclusive.

How is the LW Series dehumidifier different from a standard dehumidifier?

Typical dehumidifiers work best in high ambient temperature conditions of between 65 to 95 degrees F (18 to 35 degrees C) and 50 to 80% relative humidity while the LW Series dehumidifiers are designed to operate in low temperature applications of 32 to 70 degrees F (0 to 21 degrees C).

In what sizes is the LW Series dehumidifier available?

The LW Series dehumidifiers are available in sizes ranging from 3 to 15 nominal tons.

Are sectioned SP systems available to allow for longer crane lifts or installation through tight spaces indoors?

All SP Series units come as a completely assembled system.  Only the longest units that will not fit on a drop-deck flatbed in one piece have a filter section that needs to be easily connected in the field (no refrigeration work!).  

Optionally, the units can come in several sections that allow for lower weight per section and smaller size.  These are pre-designed sections that have been specifically created to allow for minimized cost and field labor.  See the General Arrangement drawings for the size and weight of the optional sections.  

Specially designed sectioned systems are available for extreme cases.  Contact your Desert Aire Representative for more details.

What refrigerant is used in the LW Series dehumidifiers?

R-407C refrigerant

When would I specify an LW Series dehumidifier?

The LW Series units are for low temperature applications ranging from 32 degrees F to 70 degrees F (0 to 21 degrees C).

Why doesn't the LW Series dehumidifier have problems with freezing?

To prevent the evaporator coil from freezing in low temperature conditions, the LW Series dehumidifiers are designed with a timer that will initiate the defrost cycle when the suction line temperature drops below 30 degrees F (-1 degree C). During the defrost cycle the blower is disengaged and all of the system's reheat capacity is diverted to the evaporator, where it quickly thaws the coil. Once the suction line temperature increases to confirm the evaporator coil has thawed, the dehumidifier can resume normal operation.

Are exploded view drawings available?

Due to the wide variety of configurations, exploded view drawings are not presently available.

How do I need to prepare the existing Desert Aire R-22 remote outdoor condenser for use with R-410A?

Using an existing Desert Aire R-22 remote condenser with a Desert Aire replacement R-410A dehumidifier is strictly dependent upon which model of Desert Aire remote condenser you're currently utilizing. If the existing remote condenser cannot be used, a new one must be purchased from Desert Aire. The following is a list of all Desert Aire basic remote outdoor condenser models and indicates whether they're compatible with one of our R-410A systems.

Model RC: No.

Model ROC: No.

Model ROCF: Yes.

Model ROCH: Yes.

Model ROCQ: Yes.

Please note that the R-22 systems use different refrigeration oil than R-410A and therefore all traces of oil and R-22 refrigerant must be removed prior to conversion to R-410A.

Can I use my existing line sets when replacing a dehumidifier that uses R-22 refrigerant with a dehumidification system that uses R-410A refrigerant?
In order to reuse line sets the following must be reviewed: 
1. The diameters of the line set must be adequate for the new appliance.
2. The line set must be Type K or Type L copper in order to withstand the higher pressures of R-410A refrigerant.
3. Brazing materials should be compliant with R-410A. If unknown the line set must be replaced. 
4. The line set must be properly flushed/cleaned of previous refrigerant & oil. 
 
Desert Aire recommends that a Line Set Analysis be completed prior to the appliance installation to determine if the line set can be reused. In most cases new line sets will be required. Please consult Desert Aire Service for any questions.

What is AireGuard?

AireGuard™ is Desert Aire’s remote monitoring and alarming tool that allows a user to easily monitor the performance of the dehumidifier on a cloud-based database at any computer or portable device. All that is required is an Ethernet Internet connection directly to the Desert Aire operating controller.

 

Information security is maintained since this is a cloud based system where the client computer only accesses the remote data servers. The unit controller transmits data to and from the cloud storage location. Communication at the controller takes place on port 80, the same port that any computer uses to communicate with the web. The existing LAN firewall is maintained and no action from the IT department is required as long as the facility has internet access.

 

Users log onto the cloud-based service to view and interact with data. No further access to your local network is required. This connection will meet all of your IT department’s security requirements. LC, LV, and LCQ Series products have an onboard Ethernet connection as standard.

 

The AireGuard interface easily brings the read and write variables in real time to the display screen. It allows the user to adjust set points remotely as well as monitor all the operating variables.

 

The Desert Aire LC/LV/LCQ Series have another feature that allows the local display interface to be duplicated on the cloud based interface. This feature allows for remote startup capabilities by Desert Aire employees.

 

Since the refrigeration system of a dehumidifier is very complex, many owners hire outside firms to maintain their HVAC units. The alarm management feature of AireGuard provides the owner with email or SMS notifications at time of occurrence. With appropriate access to the Desert Aire dehumidifier unit via the cloud, the servicing contractor or Desert Aire may be able to evaluate the unit’s alarm with corrective action without visiting the site.

AireGuard is included with each LC/LV/LCQ unit and includes a two year subscription to the cloud data storage. Renewal subscriptions can be purchased after expiration. View the AireGuard brochure.
