Wärmepumpen-Testzentrum WPZ (Heat Pump Testing Center)

Climatic Chamber

The Wärmepumpen-Testzentrum has three climatic chambers. The two large ones can be used separately or they can be combined. If used separately, equipment and prototypes can be tested under different climatic conditions.  

When combined the climatic chambers can be used as a heat source or heat sink. The third small climate chamber can be employed very flexible. It was developed and built at the Institute for Energy Systems.
