What Problems Can Be Caused By Low Pressure Failure of Chillers

Web19 dec. 2024 · Suppose the maximum lift of chiller is from 300kpa to 900kpa.That means it takes the refrigerant in from evaporator at pressure of 300Kpa & compress it to maximum pressure of 900kpa to deliver it to condenser. So the Chiller lift is 900-300=600Kpa. Now if the pressure at condenser side reaches to 1000Kpa, which is way high beyond the max ... Web16 nov. 2024 · What is Suction Pressure? 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.
