17 - SPECIFIC DETAILS FOR UNITS WITH A FAN
WITH AVAILABLE STATIC PRESSURE (30RQSY)
Selection based on the pressure drop
The cooling and heating capacities are given for an available
pressure of 160 Pa and for a unit without filter.
To calculate the performances at other pressure drops please
use the correction factors below.

18 - PARTIAL HEAT RECLAIM USING DESUPER-HEATERS (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 30RQS/30RQSY
range.

Note:
Pressure drop, clean filter = 6 Pa
Pressure drop, dirty filter = 12 Pa
A plate heat exchanger is installed in series with the air
condenser coils on the compressor discharge line of each
circuit.
The control configuration for the desuperheater option is
factory assembled.
