During normal operation of the air conditioning system, the readings of the low pressure gauge will be 0.15-0.25 MPa, the readings of the high pressure gauge will be 1.37-1.57 MPa. The temperature on the inlet pipeline should be 30-35°C, at a crankshaft speed of 1500 rpm. In this case, the mode selection switches must be in the following positions: air cooling - maximum, air flow rate - maximum.
