Issues with the suction pressure of the refrigeration compressor
Thread Content
Improving the efficiency of a refrigerator – will the suction pressure of the refrigerator increase?
When the evaporation rate remains constant, the suction pressure will decrease.
With a constant rate of evaporation and unchanged pressure on the low-pressure gauge, when the energy level is increased, the same amount of R22 is compressed in the compressor; as a result, the exhaust temperature rises. An increase in temperature leads to an increase in exhaust pressure, as well as in suction pressure, while the reading on the low-pressure gauge decreases
