9.1 Partial energy recovery
A conguration 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 capacity + compressor
power input)
The recovery exchanger must be always maintained full of water
The lack of water amplies the noise generated by the operation
When the temperature of the water to be heated is particularly low, it is wise to insert a ow-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.
