Unit model
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 25 to 30% 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 30 to 55°C at the same time. This is achieved
thanks to a water-refrigerant 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.
