Water - refrigerant heat exchanger
Evaporator
Refrigerant
• The unit includes a brazed plate water-refrigerant heat exchanger.
In the 30RA model the heat exchanger operates as a refrigerant
expansion evaporator whereas in 30RH units it operates as an
evaporator in the summer cycle and as a water-cooled refrigerant
condenser in winter cycle.
• Check if characteristics of the water in the refrigerant circuit are
correct. If necessary, treat water as appropriate.
