3 Technical description

3.1 Performance scope

CAIRpool units are used for energy-efficient air dehumidification in swimming pools

and humid rooms. Due to their modular design, units can be configured 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.

CAIRpool 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, 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, CAIRpool 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 the modular design of the CAIRpool, units ship as complete assemblies or

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

installation. CAIRpool units are also suitable for the modernization 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 CAIRpool

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 examples demonstrating the basic unit design and its operating

principles.

3.2.1 PPI/PPR Units with double-recuperator and heat pump

The CAIRpool PPI/PPR is designed for various kinds of High Performance private and

public swimming pools. The series can be supplied with air volume capacity between

750 up to 36000 m³/h. The unit's function is to dehumidify and heat air in swimming

pools in mixed air mode.

Together with a heat pump this unit type is additionally equipped with an efficient heat

recovery system using a two stage recuperator. The unit is delivered with a DDC con-

trols which regulates all functions of the system on a fully automated basis.

FläktGroup DC-2015-0103-GB R5-02-2020 • Subject to modifications15

The units dehumidify through a 24 h fresh air regulation. The accumulation of odors or

toxic gasous pollutants in form of trihalogenmethanes, chloramines or other corrosion-

promoting substances is reduced continuously. According to the required dehumidifi-

cation demand, larger or smaller quantities of outdoor air are used. The regulation is

performed continuously within range of 0-100%. To ensure this, a highly sensitive

humidity sensor controls the extract-air humidity of the swimming pool in the extract-

air fan chamber. Furthermore, the fully automated DDC control sets the required out-

door-air rate for the dehumidification. The outdoor air is pre-warmed via the recupera-

tor. The compressor unit operates as a heat pump and ensures the residual heat at the

default setpoint temperature. The downstream heater bank is regulated at low outdoor-

air temperatures or in case of heating up.

In the pool mode outside air and extract air dampers are open to ensure a pre-set min-

imum rate of outside air for hygienic reasons according to VDI 2089 to at least 30%.

Depending on the swimming pool humidity requirement the outside/extract air rate is

regulated automatically.

Using an optimal pool or fresh-water condenser a certain amount of excess energy

produced by the heat pump can be fed back into the pool water or a tank.

In the event of overheated swimming pool the heat pump is reduced and the supply air

bypass damper ensures cool air in the swimming pool. The bypass damper is contin-

uously opened to divert the heat recovery facility depending on requirements.

The PPR units are equipped with a reversible refrigeration circuit. Therefore, the swim-

ming pool temperature can be kept constant during the summer time and high external

loads according to the setting.

For both versions, the function of the heat pump depends on the outdoor-air rate. The

technical characteristics determine the running time and function of the compressor.

The compressor is regulated via frequency inverter and is operated via DDC in the pos-

sible working area on a fully automatic basis.

3.2.2 PPX units with double-recuperator

The CAIRpool PPX is designed for various kinds of High Performance private and pub-

lic swimming pools. The series can be supplied with air volume capacity between 750

up to 36000 m³/h. The unit's function is to dehumidify and heat air in swimming pools

in mixed air mode.

The heat recovery is performed via a highly-efficient two stage recuperator. It can be

delivered with/without DDC controls. When using DDC the controller regulates all func-

tions of the system on a fully automatic basis.

air fan chamber. Furthermore, the fully automated DDC control sets the required out-

door-air rate for the dehumidification. The outdoor air is pre-warmed via the recupera-

tor. The downstream heater bank is regulated for the remaining temperature control.

In the pool mode outside air and extract air dampers are open to ensure a pre-set min-

imum rate of outside air for hygienic reasons according to VDI2089 to at least 30%.

Depending on the swimming pool humidity requirement the outside/extract air rate is

regulated automatically.

In the event of overheated swimming pool the recuperator block is diverted and fresh

outdoor air is conveyed into the swimming pool via the supply air bypass damper. The

bypass damper is continuously opened to divert the heat recovery facility depending

on requirements.

Technical description

CAIRpool

20 FläktGroup DC-2015-0103-GB R5-02-2020 • Subject to modifications

CAIRpool units are designed for the dehumidification of swimming halls by using outside air. At outdoor temperatures [Tj] shown above, the amount

of outdoor air is 30% of the supply air flow Units operate under operating conditions of return air temperature of 30°C, therefore a defrost mode is

not necessary
