Figure 8

Sketch map of measuring point position where 1: compressor; 2: testing sensor of inspiration temperature; 3: evaporator; 4: throttle valve; 5: temperature measurement sensor for liquid supply after liquid accumulator; 6: refrigerant flow testing instrument after liquid accumulator; 7: liquid accumulator; 8: temperature measurement sensor for liquid supply before liquid accumulator; 9: refrigerant flow testing instrument before liquid accumulator; and 10: condenser. Refrigerant flow rate and temperature test should be preferred at 8 and 9 locations. When this part does not meet the test conditions, choose the location of 5 and 6.
