Pool Dehumidification Units are high-efficiency HVAC systems designed to reduce excessive humidity generated by evaporation in indoor pool areas, maintain required comfort conditions, and protect building components. These units integrate dehumidification, heat recovery, fresh air conditioning, and air circulation functions within a single framework.

Technical Features and System Components

✔ High-Efficiency Heat Recovery System

Energy transfer from exhaust air to fresh air via plate or rotary heat recovery exchangers

Low pressure drop with high thermal recovery efficiency

Special corrosion-resistant coatings suitable for swimming pool environments

✔ Direct Expansion (DX) or Chiller-Integrated Dehumidification

Cooling the humid air below its dew point for effective moisture removal

Condensed water drainage through an integrated drain line

Energy-efficient operation with high COP compressors

Optional inverter-driven compressors for modulating capacity control

✔ Corrosion-Resistant Structure and Coils

Epoxy-coated evaporator and condenser coils

Galvanized or aluminum casing resistant to pool chemicals

Stainless steel fasteners and hardware

✔ High-Efficiency Fan–Motor Assembly

Plug fan solutions with EC or AC motor options

Low energy consumption with high static pressure capability

Dynamically and statically balanced fans ensuring minimal vibration

✔ Filtration System

Standard G4 or M5 pre-filters

Optional carbon filters or high-efficiency filtration modules

Easy-to-remove cassette filter design

✔ Automation and Control Unit

PID-controlled humidity and temperature regulation

Precise airflow management with fresh air, mixing, and exhaust dampers

Modbus or BACnet communication for BMS integration

Fan speed control compatible with inverter drives

Operating Principle

Humid air extracted from the pool area is passed through the cooling coil and cooled below its dew point, enabling moisture removal.

The condensed water is discharged via a dedicated drainage line.

The heat generated at the condenser side of the refrigeration cycle can optionally be recovered for pool space heating or rejected outdoors.

The heat recovery exchanger transfers thermal energy from exhaust air to the incoming fresh air.

All processes are monitored by the control system, and operating modes are automatically optimized.
