5 in 1 Pool Dehumidification Heat Pump

Integrates pool-room dehumidification, air cooling and heating, pool-water heating, ventilation coordination and heat recovery in one controlled system. Designed for indoor pool projects where humidity, room temperature, water temperature and air balance must work together.

Air Dehumidification Air Cooling & Heating Pool-Water Heating Fresh-Air & Exhaust Coordination Heat Recovery & Energy Routing

Fresh-air volume, exhaust strategy, pool-room pressure and duct external static pressure must be confirmed through project-specific mechanical design, control logic and commissioning.

Product structure

Five Functions, One Control Strategy

The controller coordinates humidity, room temperature, pool-water demand, ventilation and recovered-energy routing according to the active operating mode and configured priorities.

01

Air Dehumidification

Removes latent moisture from return air to support the target pool-room relative humidity.

02

Air Cooling & Heating

Responds to the room's sensible cooling or heating load across seasonal conditions.

03

Pool-Water Heating

Directs available heating capacity to the pool-water circuit when required by the control mode.

Integrated Control Core

Sensors, load priorities, fans, refrigeration circuit, dampers and project control interfaces

04

Fresh-Air & Exhaust Coordination

Coordinates the designed outdoor-air and exhaust-air paths according to the project ventilation strategy.

05

Heat Recovery & Energy Routing

Reuses available energy from dehumidification and exhaust processes for supply-air treatment or pool-water heating, subject to the selected configuration, operating mode and simultaneous loads.

Five functions do not mean five simultaneous full-capacity outputs. Outdoor-air volume, exhaust balance, pool-room pressure, duct static pressure, BMS points and operating priorities must be defined and commissioned for each project.

Design Every Air Path as One System

A commercial indoor pool requires controlled recirculation, supply-air distribution, outdoor air and exhaust—not only moisture removal. Each path must support humidity control, glazing protection, occupant comfort and the designed pressure relationship.

RETURN Collect warm, humid pool-room air from high-moisture zones without short-circuiting the supply path.
TREAT Filter and dehumidify the air, then cool or reheat it according to the room load and operating mode.
SUPPLY Distribute conditioned air across glazing, exterior surfaces and occupied zones at the designed volume and throw.
VENTILATE Balance outdoor-air intake and exhaust air according to the indoor-air-quality and pressure strategy.

Final airflow, outdoor-air rate, exhaust balance, pool-room pressure, duct external static pressure and diffuser arrangement must comply with local codes and the approved mechanical design.

Prepare Four Data Groups Before Model Selection

Capacity, airflow, heat routing and control sequences are interdependent. Complete project inputs reduce model reselection and late changes to ductwork, controls or plant-room layout.

Pool Load

  • Exposed water surface and connected spas
  • Design water temperature
  • Activity level and bather occupancy
  • Pool-cover and operating schedule
  • Pool-water heating requirement

Room & Envelope Load

  • Room volume, air temperature and target RH
  • Glazing, walls, roof and insulation data
  • Lighting, occupants and internal gains
  • Summer sensible cooling load
  • Condensation-control requirements

Ventilation & Ductwork

  • Outdoor summer and winter design conditions
  • Required outdoor-air volume
  • Exhaust balance and negative-pressure strategy
  • Supply- and return-air arrangement
  • Required duct external static pressure

Controls & Utilities

  • Occupied and unoccupied schedules
  • Air-side and water-side priorities
  • BMS protocol, points list and interfaces
  • Remote alarms, safeties and interlocks
  • Power supply and applicable standards
Send drawings before the equipment configuration is finalized We can review the preliminary latent load, sensible load, airflow, heat-routing priorities and project interfaces.

Technical note: these values describe the series range. Individual model performance varies with entering-air conditions, pool-water temperature, outdoor-air ratio, airflow, external static pressure and operating mode.

5 in 1 Pool Dehumidifier FAQ

Resolve the main system questions before tender comparison or final equipment selection.

Discuss Your Pool Project →
What is the difference between the 3 in 1 and 5 in 1 series?
The 3 in 1 series focuses on dehumidification, air heating and pool-water heating. The 5 in 1 series adds active air cooling/heating coordination, fresh-air/exhaust-air management and broader heat-recovery control for commercial projects with more complex ventilation and seasonal loads.
Can the unit control negative pressure in the pool hall?
It can coordinate configured supply, fresh-air and exhaust-air volumes, but the required pressure relationship must be designed and commissioned for the whole building. Door leakage, adjacent spaces, independent exhausts, duct balancing and local code requirements all affect the result.
Is the outdoor-air rate fixed?
No. Outdoor-air quantity should follow occupancy, air quality, local codes and the approved mechanical schedule. If a variable fresh-air ratio is required, provide the minimum/maximum airflow, control signal and corresponding external static pressure during selection.
What information is required to confirm heat-recovery performance?
Provide return and outdoor design conditions, exhaust and fresh-air volumes, pool-water temperatures, air-side heating/cooling loads and the intended operating sequence. Heat available from dehumidification or exhaust air changes with mode and simultaneous demand.
Which OEM options are available for distributors and project orders?
Subject to order volume, engineering feasibility and certification scope, options may include branding, cabinet arrangement, airflow direction, filter grade, controller language, communication interface, packaging and documentation. Share the target market, annual volume and mandatory standards for review.
