The available special versions are described below:
VB: Standard unit.
VD: Version with Desuperheater (available forboth IR units and IP units)
Produces cold water in the same way as the standard version plus hot water from 30 to 70°C at the same time. This is achieved by installing a
water-refrigerant gas heat exchanger between the compressor and coils in order to recover 20 to 25% of the heating capacity that would otherwise
be dispersed in the air.
It helps to remind that hot water production is possible only in combination with cold-hot water production in the main heat exchanger and it is
subordinated by it.
VR: Total Heat Recovery version
Produces cold water as in the standard version plus hot water at a temperature of 35 to 55°C at the same time. This is achieved thanks to a waterrefrigerant
gas heat exchanger that totally recovers the heating capacity that would otherwise be dispersed in the air. The total heat recovery
function is enabled and disabled by means of a valve on the compressor delivery of each circuit: when the temperature of the water that enters
the recuperator drops, the valve switches the hot gas flow from the condensing coils to the recovery heat exchanger. On the other hand, when the
temperature of the water reaches the set-point, the valve shuts off the heat recuperator and switches the hot gas flow to the condensing coils.
It helps to remind that hot water production is possible only in combination with cold water production in the main heat exchanger and it is subordinated
by it.
