Heat recovery

Units may be optionally equipped with heat recovery system. This system is 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 respect of this value (e.g. using

recirculatingbypassvalve).

Water treatment

Beforeputtingtheunitintooperation,cleanthewatercircuit.Dirt,scales,corrosiondebritsandothermaterial

canaccumulateinsidetheheatexchangerandreduceitsheatexchangingcapacity.Pressuredropcanincrease

aswell,thusreducingwaterflow.Properwatertreatmentthereforereducestheriskofcorrosion,erosion,
