10.7 - Partial heat reclaim using desuperheaters (option 49)
This option permits the production of free hot water using heat reclaim by desuperheating the compressor discharge gases. The option
is available for the whole 30RQM/30RQP range.
A plate heat exchanger is installed in series with the air heat exchanger coils on the compressor discharge line of each circuit.
The control configuration for the desuperheater option is factory assembled (see chapter 10.7.8 "Control configuration").
The installer must protect the heat exchanger against frost.
