3 Technical Description

3.1 Performance scope

FläktGroup CAIRfricostar units are used for energy-efficient air dehumidification in

swimming pools and humid rooms. Due to their modular design, units can be config-

ured individually to meet particular air-handling requirements and specifications. The

transported air can be filtered, heated, cooled and dehumidified, depending on the

application for each case. The aim is to meet the customer specifications concerning

required air volume and conditions.

FläktGroup CAIRfricostar units are used at a central point for comfort air conditioning

on commercial and industrial premises for the transportation and treatment of “normal”

air (according to VDI 2089).

A range of unit components is available for energy-saving purposes: plate-type heat

exchangers, heat pipes, liquid-coupled heat exchangers and heat pumps with a heat

recuperation function.

Units are performed in different sizes and have various capacities. Depending on the

application for each case, FläktGroup CAIRfricostar units are designed for horizontal

air flow and are arranged as double-deck and side-by-side models. Units are only

designed for indoor installation. Units for outdoor installation need have special design.

Thanks to their modular design FläktGroup CAIRfricostar units ship as complete

assemblies or sub-assemblies that can pass through the available on-site openings in

the course of installation. FläktGroup CAIRfricostar units are also suitable for the mod-

ernisation and retrofitting of existing buildings due to the number of available unit sizes

and a unit ordering option providing for delivery in small shipment units.

3.2 Modular unit configuration and operation of FläktGroup CAIRfricostar

Thanks to the modular design of the units and various applications for each case, a

customer can select a wide range of unit configurations.Refer to the following exam-

ples demonstrating the basic unit design and its operating principles.

3.2.1 CAU units

The FläktGroup CAIRfricostar CAU is designed for private swimming pools and are

available in 4 sizes. The unit's function is to dehumidify and heat air in swimming pools

in recirculating-air mode. The unit is fitted with a fully electronic control system that

automatically regulates system functions.

Fig. 3-1: FläktGroup CAIRfricostar CAU

In recirculating-air mode without dehumidification the air is recirculated in the swim-

ming pool. The multifunction humidistat that is installed in the swimming pool switches

the unit into dehumidification mode as soon as the humidity setpoint has been

exceeded. At this point the fan is operated at nominal air-flow volume and the refriger-

ation system is activated. Dehumidification is active until the humidity setpoint is

reached. Subsequently the fan is switched back and the circuit compressor is stopped.

Using an optional pool water condenser a certain amount of excess energy produced

by the refrigeration cycle can be fed back into swimming pool water.
