3 in 1 Pool Dehumidification Heat Pump

Designed for indoor swimming pools, the system dehumidifies recirculated air, reheats supply air and transfers recovered heat to pool water. Coordinated air- and water-side operation helps control humidity while reusing energy that would otherwise be rejected.

Air Dehumidification Air Reheating Pool Water Heating

The unit primarily treats recirculated pool-room air. Project-specific fresh air, exhaust air and building pressure control must be coordinated with the overall ventilation design.

See Where the Recovered Heat Goes

Warm, humid return air passes through the refrigeration circuit, where moisture is condensed and usable heat is captured. The control system can then direct that heat to supply-air reheating or pool-water heating according to operating demand.

1
Remove Moisture Humid return air is cooled below its dew point, allowing water vapour to condense and drain away.
2
Capture Usable Heat The refrigeration circuit collects heat from the return-air stream instead of rejecting it directly.
3
Reheat Air or Pool Water Recovered condenser heat is routed according to the selected operating mode and current air- or water-side load.

System boundary: recovered heat can offset part of the air- or water-heating demand. The contribution varies with evaporation load, operating mode, setpoints and project conditions; auxiliary heat may still be required.

Three Functions, One Coordinated System

The refrigeration circuit removes moisture from pool-room air, while the controller allocates available recovered heat between supply-air reheating and pool-water heating according to operating demand.

01

Air Dehumidification

Humid return air is cooled below its dew point so water vapour condenses and drains from the unit.

Helps maintain the target relative humidity and reduce condensation risk.
02

Supply-Air Reheating

Available condenser heat reheats the dehumidified air before it returns to the indoor pool space.

Reduces the cold-air effect and supports stable pool-room temperature.
03

Pool-Water Heating

Available recovered heat is transferred through the water-side circuit to the pool-water loop.

Offsets part of the pool heating load when operating conditions permit.

These are coordinated functions, not three independent full-capacity systems. Final heat allocation depends on the air-side load, water-side load, operating mode, hydraulic design and selected model.

Size from the Evaporation Load—Not Floor Area Alone

Moisture load is driven by exposed water surface, water and air temperatures, pool activity and the operating schedule. Two pool halls with the same floor area can require very different dehumidification capacities and airflow.

Pool-cover effect: provide occupied and unoccupied schedules separately. Consistent cover use can materially reduce evaporation during closed periods and change the required operating load.

Eight inputs for preliminary system selection
01 Exposed Water Surface Main pool, connected spa and other open-water areas
02 Water Temperature Normal design setting and maximum operating condition
03 Pool-Room Setpoints Design air temperature and target relative humidity
04 Activity & Occupancy Pool use, bather load, water features and activity level
05 Schedule & Pool Cover Occupied hours, closed periods, cover use and setbacks
06 Outdoor Climate & Envelope Design weather, glazing, insulation and condensation risk
07 Room Volume & Airflow Pool-hall volume and required supply and return airflow
08 Ductwork & Utilities External static pressure, power, drainage and plant layout

3 in 1 Series Performance Range

Use these series ranges for initial screening. Final model selection should be based on the calculated moisture load, required airflow and available external static pressure, with performance checked at the project's air and water conditions.

Dehumidification Capacity
5–30 kg/h
Nominal Airflow
1,500–8,000 m³/h
Pool-Water Heating Capacity
10–60 kW
Air-Heating Capacity
12–70 kW
Available External Static Pressure
200–500 Pa
Humidity-Control Range
50–70% RH, project setpoint
Controller / BMS
Touch controller; RS485 / Modbus optional
Refrigerant
Model- and market-specific

Technical note: these values describe the series range. Individual model performance varies with entering-air conditions, pool-water temperature, airflow and operating mode. Refer to the model table for rated conditions, electrical data, dimensions, refrigerant and certification scope.

3 in 1 Pool Dehumidifier FAQ

Answers for contractors, consultants and project buyers comparing indoor pool humidity-control systems.

How is the correct dehumidification capacity selected?
Selection should be based on calculated evaporation, not room area alone. Provide pool surface area, water and room temperatures, target RH, activity level, occupancy schedule, cover use, climate and room volume. Airflow and duct static pressure must also be checked.
Can recovered heat maintain the pool water temperature by itself?
It may offset a substantial part of the water-heating load, but whether it covers the full load depends on moisture generation and simultaneous water losses. The system designer should retain suitable auxiliary heat where peak or start-up demand exceeds recovered capacity.
Does a 3 in 1 unit replace the project ventilation system?
No. This product focuses on recirculating-air dehumidification, air heating and pool-water heating. Required outdoor air, exhaust, pressure control and code compliance remain part of the ventilation design. For integrated fresh air and exhaust management, compare the 5 in 1 series.
Where should chemical dosing and water connections be located?
Follow the approved hydraulic schematic. Chemical dosing is normally arranged downstream of heating equipment, with compatible materials, correct flow, filtration and an independent circulation arrangement where required. Final positions must follow local codes and the supplied manual.
What OEM options can be discussed?
Depending on volume and certification scope, options can include logo and colour, cabinet arrangement, airflow direction, controller interface, packaging, manuals and electrical configuration. Send the target market, annual quantity and mandatory standards for feasibility review.
