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 Te ≤ -1°C for 20 minutes
accumulated => Change
target Te ≥ 5°C
P Te ≤ -1°C for 30 minutes
accumulated => Change
target Te ≥ 8°C
