Chiller low suction pressure
Did you know?
WebA suction pressure low superheat condition occurs when the capacity regulator is large because of which it feeds in more refrigerant into the coils of the evaporator as the heat load is not enough for the available refrigerant. Another possible reason for this condition could be the high capacity of the thermal expansion valve. WebIn the air conditioning system if the suction side the pressure is increasing continuously then the low head pressure will be increasing inside the system. When the refrigeration system continuously faces the less temperature the amount of capacity will be also decreases. High suction pressure normal head pressure:

WebTake the suction pressure and use the pressure/temperature chart to convert it to temperature. Let’s say the suction pressure is 60(Psi) which converts to 34F. And assuming that the suction line temperature is 44F. Then to get superheat we just get the difference between the two temperature readings. In this case, we have 10F of superheat. WebNov 16, 2024 · Suction pressure – also known as “low side pressure” – is the pressure at the intake point of the compressor in an air conditioner. Suction pressure is measured when the air conditioner runs and the compressor is pulling refrigerant into it. It is typically 100 PSIG but it can vary depending on brand and model.
