How does SPD pool Room Dehumidifier work?

How pool room dehumidifier works?

The SPD indoor pool dehumidifier uses a refrigeration system like air conditioners. As a result, it removes heat and moisture from incoming air. After that, dry get a discharge in the room. Hot, high-pressure refrigerant gas routed from the compressor to the condenser coil. Let’s understand the working process of the SPD pool room dehumidifier.

CtrlTech dehumidifier Dubai offers various models. They also offer FD30E and CD-25L home dehumidifier.

The process for indoor pool humidity control.

The refrigerant gets cooled and condensed by giving up its heat to the air that is about to discharge. After that, the refrigerant liquid then passes through a strainer and capillary tubing. This process causes the refrigerant pressure and temperature to drop. Further, It enters over the evaporator coil. Here it absorbs heat from the incoming air and evaporates.

The evaporator operates in a flooded condition. In other words, all the evaporator tubes contain liquid refrigerant during regular operation. A flooded evaporator should maintain constant pressure. Also, it should keep a fixed temperature across the entire coil of a pool room dehumidifier. All this process is to reduce indoor pool humidity.

Meanwhile, the mixture of gas and liquid refrigerant enters the accumulator. Before that, refrigerant leaves the evaporator coil of the indoor pool dehumidifier. The function of the accumulator is to prevent liquid refrigerant from the compressor. The compressor evacuates the cold refrigerant gas from the accumulator. And then accumulator compresses it to high pressure and temperature.

Indoor pool dehumidifier controller.

Indoor pool humidity controller.

The SPD indoor pool dehumidifier features a built-in humidistat. Besides, it has a facility to connect the controller. This controller meant to installed away from the actual unit. Hence, the user can operate the unit with convenience. By default, each SPD unit supplied with one wall mount controller. This controller has an LCD with control buttons.

Where to install a controller?

Most importantly, the controller should install in the area which needs to dehumidify. Effect of that, the controller can sense indoor pool humidity with accuracy. Please note, based on controller feedback, a compressor with switch on and off. Always try to install the controller in the middle of the room so that it can sense humidity. And, avoid stoping of pool room dehumidifier even though high moisture in the room.

Make sure that controller wire connected as per manufacturer’s instructions. SPD indoor pool dehumidifier manual will guide you with the proper installation procedures.

Pool room dehumidifier installation configurations.

SPD series unit can install in five to six different ways. These configurations based on how it connected to the HVAC system. There are the following types of installations:

Parallel to the central return duct.

In this configuration, the pool room dehumidifier connected in parallel with the return. Which means, intake is from return duct and dry air discharge is also to return duct.

Main return duct to main supply duct.

In this method, the indoor pool dehumidifier connected in parallel with the AC unit. Intake of air is from the central return duct and discharge of dry air into the main supply duct. Hence, it needed to install a backdraft damper at the outlet of SPD. This process is to avoid backdraft when the dehumidifier is off, and AC is working.

Dedicated return to the main supply.

If you like to dehumidify a specific area, then use this configuration. The unit takes intake from the dedicated return from that particular area. And then discharge dry air into the central supply duct. Here again, we need to install a backdraft damper at the discharge of the SPD pool room dehumidifier.

Dedicated return to the main return.

This configuration is like the previous one. Except, the discharge of dry air is into the central return duct instead of the main supply duct.

Unducted installation of indoor pool dehumidifier.

This configuration used when indoor pool humidity needs to reduce in a closed room. In such a case, an indoor pool dehumidifier can install without any ducting. If the room is big, then it needs to do ducting for inlet and outlet. Or else, install many units.

Other methods of ducting with fresh air or with forced air HAVC are as follow:

Advantages of fresh air dehumidification.

In particular, residential buildings need a fresh air intake. It is always recommended to dehumidify this fresh air before feeding it to HVAC. For this, the SPD pool room dehumidifier needs to install a fresh air duct. Advantages of this form of ventilation include

  • Outside air gets filtered before entering the building.
  • Outside air gets dehumidified before entering. Thus, indoor pool humidity maintains inside the home.
  • Drawing air from outside and blowing inside adds positive pressure in structure. Hence, this helps to prevent dirty and humid air from entering elsewhere.
  • SPD indoor pool dehumidifier reduces the threat from carcinogenic radon gas. Also, it provides a small amount of make-up air for open combustion and exhaust devices. For example, it offers make-up air for the clothes drier, fireplace, and water heater.
  • Exhaust fans recommended in the bathrooms and Kitchen. In cold climate countries, ventilation used to dehumidify the building. SPD pool room dehumidifier dehumidifies fresh air at the inlet. This accomplished by bringing the dry, low dew point air into the structure. Hence, making the SPD dehumidifier capable of year-round drying.
  • This approach is cheaper than using a dehumidifier to reduce moisture in the entire home. In cold climates, enough ventilating is critical to reducing the inside moisture content. And to avoid moisture accumulating in the wall cavities. It is also an effective solution for indoor pool humidity control.

Important tip.

In winter, we often observe condensation on the interior surface of glass windows. If you are facing the same issue, then increasing ventilation solves the problem. Large quantities of outside air will impact SPD pool room dehumidifier performance.

If it is a positive or negative effect is dependent upon the inside and outdoor air conditions. The outer air duct should connect to the front of the unit. With a standard damper, the amount of outside air can restrict.

Swimming pool humidity control.

Indoor pool dehumidifier installation in a Basement or Crawlspace.

Install a separate return for the SPD indoor pool dehumidifier in a central area. Duct the other side of the unit to the air supply of the existing HVAC system. Do not forget to install a backdraft damper.

For crawlspace also, install a separate return for the SPD pool room dehumidifier. Duct the other side of the unit to the air supply of the existing HVAC system with a backdraft damper.

We can avoid installing a separate return to the SPD for indoor pool humidity control. If the existing system has many returns, then you can use one of them.

Always select a return from a central location in the structure. The central area that always open to the rest of the structure. Do not use a return from a room that may have its door closed much of the time. Or, install a separate return from the open part of the house.

Installation in an Attic with an existing forced-air HVAC system.

If SPD dehumidifier installed above a finished area then, use a secondary drain pan. Likewise, install a drain pan for the area where water leakage could cause damage. Always use an overflow interrupter switch.

The preferred installation is to create a separate return for the SPD dehumidifier. Duct the supply of the SPD indoor pool dehumidifier to the air supply of the existing HVAC system.

Pool room dehumidifier used for pool room humidity reduction.

Installation in a Structure with no existing forced-air HVAC system.

In such a situation, a single return for the SPD dehumidifier must install in the central open area. DO NOT locate the return in a bathroom or a kitchen. The supplies of the SPD pool room dehumidifier must situate at the remote areas of the structure (such as bedrooms, den, etc.). By ducting this way, the air inside will circulate through the SPD dehumidifier.

Maintenance of SPD pool room humidity controller.

The SPD dehumidifier always equipped with a G4 filter. This filter must check every three months. Operating the unit with a dirty filter will reduce dehumidifier capacity and efficiency. And may cause the compressor to cycle off and switch on defrost control. To clarify, do not operate the unit without a filter or with a less-effective filter.

If you operate the unit without a filter, then it may cause internal damage to the system. Worth to note that such damages not covered under warranty. To replace the filter, remove the filter door from one of the sides of the SPD indoor pool dehumidifier. You can access filter, by pushing the snap button in and pulling to door away from the body of the unit. Insert the new filter in the same manner.
