This system in made by a water cooled heat exchanger located on the compressors discharge pipe and a dedicated
management of condensing pressure.
To guarantee compressor operation within its envelope, units with heat recovery cannot operate with water temperature of
the heat recovery water lower than 25°C.
It is a responsibility of plant designer and chiller installer to guarantee the resp ect of this value (e.g. using recirculating
bypass valve).
