ThermoCond 38

AIR VOLUME FLOW: 2,600 – 35,100 m³/h

Air conditioning unit with counterflow plate heat exchanger for medium-sized and large public swimming pool halls

Devices of the series 38 achieve a very high energy efficiency, since the integrated program only adds as much air as is required for dehumidification of the pool hall air. ThermoCond 38 dehumidifies exclusively with outside air. The design ensures the cleanability according to VDI 6022. The integrated counterflow plate heat exchanger reaches a real counter flow share of 80% with highest heat recovery rates. Optionally the device can be equipped with a fresh water heater for an even more efficient use of the heat energy contained in the exhaust air.

Functional description

Standby mode

If no requirements are specified regarding temperature regulation or dehumidification when the swimming pool hall is in standby mode, the system operates only in recirculation mode. The air circulation in the swimming pool hall is guaranteed, with the fans working at a lower capacity.

Recirculation Air Operation (heating)

The heating coil heats the swimming pool hall as required in recirculation mode. In order to reduce the internal pressure losses, the recirculation air defrost damper is also opened. The outside air and exhaust air dampers are closed.

Bathing Mode and Standby mode with Dehumidification Requirement

The swimming pool hall is dehumidified through the addition of outside air to the recirculation air volume flow. In swimming pool mode the minimum required amount of outside air is added to the recirculation air for hygienic reasons (VDI 2089). The proportion of outside air depends on the current evaporation of water (and therefore the occupancy level of the swimming pool hall), as well as the outside air humidity. This is continuously and automatically adjusted. If the waste heat recovery is not sufficient for achieving the desired supply air temperature, the supply air is reheated in the heating coil.

Outside Air / Exhaust Air Mode

In the case of rising outside air humidity, the recirculation air damper is continuously closing as required. When the outside air humidity is high, the damper closes completely. The system works at 100% outside air / exhaust air operation through the counterflow plate heat exchanger.

Recirculation Air Operation (heating)

The heating coil heats the swimming pool hall as required in recirculation mode. In order to reduce the internal pressure losses, the recirculation air defrost damper is also opened. The outside air and exhaust air dampers are closed.

As an option

the device unit be equipped with the heat exchanger bypass. The proportion of the air guided through the heat exchanger and the bypass can be regulated as required up to free ventilation.
