The high degrees of exchange make it possible to use cooling and heating sources that were previously unknown as such:

20 °C in summer for cooling
25 °C in winter for heating

In the cooling case, free cooling can be used particularly efficiently, e.g. in GSWT® closed-circuit systems - or the chiller used for this purpose operates with high coefficients of performance of > 7 (e.g. at 16 / 24 °C).

In the case of heating, the last calorie of heat can be used - or a heat pump operates with coefficients of performance of 6, 7 or even 8 - or low-temperature waste heat < 25°C can be used.

In any case, GSWT® room air conditioners lead to a significant increase in efficiency of peripheral systems as well as the entire TGA.

The use for data centers leads to lowest air volumes and maximum electricity savings.

In combination with the GSWT® recooling units, 70 % to 100 % of free cooling can be generated!
