Partial energy recovery
Option
A configuration which enables the production of hot water free-of-
charge while operating in the cooling mode, thanks to the partial
recovery of condensation heat that would otherwise be rejected to
the external heat source.
The maximum capacity available from the partial recovery is equal
to the 15% of the rejected heating capacity (cooling ca
compressor power input)
The recovery exchanger must be always maintained full of water
The lack of water amplifies the noise generated by the operation
When the temperature of the water to be heated is particularly
low, it is wise to insert a flow-rate control valve into the system
water circuit, in order to maintain the temperature at the recovery
output at above 35°C and thus avoid the condensation of the
refrigerant into the partial energy recovery device..
