Construction and Components
Carpentry
The structure of the HHA units is made from galvanised steel sheet with anti-corrosion treatment and finished with powder-coated paint in an oven, ensuring high resistance in aggressive environments such as indoor pools with chlorine presence. The modular design with removable panels allows full access to internal components, facilitating maintenance, inspection, and cleaning operations.
Refrigeration circuit
The refrigeration circuit operates through direct expansion with R410A refrigerant and incorporates high-performance hermetic compressors, designed to work under continuous high humidity conditions. The system includes an expansion valve, dehydrator filter, safety pressure switches, and service valves, ensuring reliable and efficient operation across the entire working range.
Compressors
Equipped with rotary or scroll type compressors depending on the model, mounted on anti-vibration supports to reduce noise levels and vibrations. They include internal thermal protection and control systems that optimise operating cycles, increasing the equipment's lifespan.
Condenser and evaporator
Thermal exchange batteries are constructed with copper tubes and high-efficiency aluminium fins, optimised to maximise thermal transfer even in conditions of high ambient humidity. The design allows for proper drainage of condensates and reduces the risk of ice formation.
Heat recovery
HHA units incorporate heat recovery systems that allow for the reuse of thermal energy extracted during the dehumidification process. This system significantly improves overall energy performance, reducing electrical consumption and contributing to the maintenance of ambient temperature.
Ventilation
Double-inlet centrifugal fans, sized to operate with high flow rates and ensure uniform air distribution in ducted installations. High-efficiency motors allow for continuous operation with low energy consumption and reduced noise levels.
Air filtration
Filtration system using easily removable air filters, designed to retain particles and protect the internal components of the equipment. They allow for simple maintenance and ensure adequate air quality in the space.
Electronic control
Advanced microprocessor that manages the complete operation of the equipment, including humidity control, temperature, defrost cycles, and alarms. It allows for the visualisation of the unit's status and integration with external control systems.
Electrical panel
Electrical panel in accordance with European regulations, equipped with a main switch, thermal magnetic protections, control relays, and safety elements. It has terminals for external connection and remote control of the equipment.
Safety and protections
The units incorporate multiple protection systems, including high and low pressure switches, thermal protection for compressors and fans, and automatic defrost control. These systems ensure safe and reliable operation even in demanding conditions.
