KEY
The performance refers to the
following conditions:
? processed water temperature =
7°C; outside air temperature =
35°C.
E processed water temperature =
50°C; outside air temperature =
7°C B.S. - 6°C B.U.
WARNING
As can be seen from the table, in choke
mode the reduction of the input power is
greater than the reduction of the output
power, hence obtaining an E.E.R. greater
than that in full load operation.
This is because, in capacity control mode,
the machine has the heat exchangers
“oversized” in relation to the respective
refrigerant capacities, thus allowing a
greater energy efficiency.
For this reason, this series of devices is
especially suitable for reducing energy
consumption with variable load (typical of
the comfort applications).
