The air -conditioning refrigeration system consists of a compressor, condenser, expansion valve, and evaporator. The working process is as follows: refrigerant boils at the pressure temperature and is lower than the temperature of the cooling object or fluid.The compressor constantly draws the vapor generated in the evaporator, compresses it to the condenser, and then sends it to the condenser to cool and condense into a liquid under pressure.The medium (usually the air used by the air conditioner of the machine room) must be higher than the temperature of the cooling medium than the temperature of the cooling medium. The liquid after the condensation enters the evaporator through the expansion valve or other throttle components.
Air conditioning condenser cleaning
⑴ Water cooling type: In this type of condenser, the heat released by the refrigerant was taken away by cooling water.Cooling water can be used at one time or recycled.The water cooling condenser can be divided into vertical shell tube, horizontal shell tube and sleeve type according to its different structural type.
又 air cooling type (also known as wind -cooled): In this type of condenser, the heat released by the refrigerant was taken away by the air.Air can be a natural convection, or a fan can be used for mandatory flow.This type of condenser is used for Freon refrigeration devices in places with inconvenient water supply or difficulty.
(3) Water and air cooling type: In this type of condenser, the refrigerant is cooled by water and air at the same time, but it mainly relies on the evaporation of the surface of the cooling water on the surface of the heat transfer pipe.Smallation potential heat, the effect of air is mainly to take away water vapor to speed up the evaporation of water.Therefore, the water consumption of such condensats is very small. For areas with dry air, low water quality, low water temperature, and insufficient water volume, it is a preferred type of condenser.This type of condenser can be divided into two types: evaporation and excitement according to the different structure type.
: Evaporation condensate: In this type of condenser, the cold effect generated by the evaporation of the refrigerant in another refrigerant system is used to cool the refrigerant steam on the other side of the heat passing wall, prompting the latter to condense liquefaction.Such as the evaporator in the folded refrigerator.
The working principle of air -conditioning condenser work
The cleaning of the air -conditioning machine should include three parts, the first air -conditioning body shell and part, which is vulnerable to pollution; the second filter was cleaned, which is the most important part of the core;Combined in one piece, equivalent to the cleaning of small systems, is a relatively large surgery. It often appears in the old air -conditioning machine or special price machine and inferior machine. Most of these air -conditioning machines do not have the value of cleaning and maintenance, and it is not detailed.
