Function and Control 71
3.11 Liquid Compression Protection 2
Outline The function will ensure a pressure differential between the high pressure and the low pressure.
This is required when cooling with low outdoor ambient temperature because HP gets weak and
you will have small capacity and a high power input.
The compressor stops according to the conditions of the outdoor ambient temperature and the
outdoor heat exchanger temperature.
