Compressor control
P
The compressor frequency is controlled in function of the target evaporating temperature.
P
The target evaporating temperature is controlled in function of the cooling load.
Minimum target Te = 2°C Minimum target Te = 0°C Initial minimum target Te =
2°C, but can be changed in
function of actual Te, to
avoid freeze up activation:
P
