The generators/receivers are each connected to the above lying con-denser and the below lying evapora-tor by flap valves.
A heat exchanger manufactured with seamless drawn copper tube (>>DIN 2.0090 SF-CU) is installed in each chamber.
The tube sheets and tubes of the heat exchangers placed in the generator/receiver are additionally packed with silica-gel granulated material.
