2 DESCRIPTION OF THE P030 CHILLER
The P030 Chiller is a unit ready for plug-in and is equipped with a refrigeration and water circuit
including all fittings and regulating/control devices required for automatic operation. The heat
extracted from the water is given off to the ambient air by means of the refrigeration circuit via the
condenser and the fans.

2.2 Refrigeration Circuit
The refrigeration circuit is a closed-loop system in which the refrigerant R134 circulates as the heat
transfer medium.
The water heated by the system separator is recooled in the evaporator (4). The liquid refrigerant is
thereby passed through the piping in a counter-flow arrangement with respect to the water. The
refrigerant evaporates as it takes up the waste heat from the cooling water of the system separator.
