1 General operation
The Split New Perfera is typically used for cooling or heating in residential
applications.
The medium which is used to transfer the heat from inside to outside or vice versa,
is refrigerant R32.

In case of cooling, the compressor builds up pressure and hence the temperature
of the refrigerant is increased. The hot refrigerant is carried to the outdoor heat
exchanger which will cool down the hot refrigerant by the fan.
The temperature of the refrigerant is further decreased by expansion through the
expansion valve. The cold refrigerant flows into the indoor unit and is capable of
taking up heat again. This is enabled by a fan that sucks indoor air over the heat
exchanger.
This refrigerant is then transported to the compressor where temperature is built
up again and the cycle restarts.
For heating, it's just the other way round.
INFORMATION
Some of the indoor unit models CAN be used as Multi application as well. For further
general operation, please consult Multi Split service manual.
