Partial Heat Reclaim Using Desuperheaters (Option 49) - Carrier AquaSnap 30RB Series Installation, Operation And Maintenance Instructions

11.3 - 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 30RB range.
A plate heat exchanger is installed in series with the air con-
denser coils on the compressor discharge line of each circuit.
The control configuration for the desuperheater option is
factory assembled (see chapter 11.3.6 - Control configura-
tion).
