Compressor control
The compressor frequency is controlled in function of the target evaporating temperature.
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:
Te
≤
-1°C for 20 minutes
accumulated => Change
target Te
≥
5°C
Te
≤
-1°C for 30 minutes
accumulated => Change
target Te
≥
8°C
