Common faults and treatment methods of centrifugal water chiller.

When the unit is cooling, the compressor sucks the low-temperature and low-pressure refrigerant in the evaporator into the cylinder, and after the compressor works, the refrigerant vapor is compressed into high-temperature and high-pressure gas.

And enter the condenser through the exhaust pipe. The high temperature and high pressure refrigerant gas exchanges heat with the cooling water in the condenser, and transfers the heat to the cooling water belt, while the refrigerant gas condenses into high pressure liquid. The high-pressure liquid discharged from the condenser is decompressed through the throttling of the thermal expansion valve and then enters the evaporator. In the evaporator, the low-pressure liquid refrigerant absorbs the heat of the chilled water and vaporizes it, cooling the chilled water, and becomes the necessary low-temperature water. The vaporized refrigerant gas is sucked and compressed by the compressor again, and then discharged into the condenser, so that it circulates every week to realize the cooling of the chilled water.

The chilled water discharged from the unit enters the indoor fan coil unit, variable air volume air conditioner and other terminal devices. During the heat exchange process between the indoor and the convective air, the water absorbs the heat of the indoor air (releases heat to the indoor air), causing the temperature to rise After the indoor air passes through the indoor heat exchanger, the temperature rises and the chilled water enters the unit again under the action of the pump to achieve the purpose of continuous refrigeration.
