Description

High-temperature-resistant kitchen air conditioner refrigerating system

Technical Field

The utility model relates to the technical field of kitchen air conditioners, in particular to a high-temperature-resistant kitchen air conditioner refrigerating system.

Background

The kitchen air conditioner refrigerating system is used for cooling a kitchen, the operation of the compressor compresses the refrigerant in the cylinder, and the refrigerant compressed by the compressor circulates in the refrigerating system in the sequence of compression, condensation, expansion and evaporation. The high-temperature high-pressure gaseous refrigerant discharged from the compressor is converted into a medium-temperature high-pressure liquid refrigerant after heat release of the condenser, then is converted into a low-temperature low-pressure liquid refrigerant through the throttling expansion device, then is subjected to heat exchange with circulating air outside the evaporator in the evaporator, absorbs heat and is converted into a low-temperature low-pressure gaseous refrigerant, and then enters the compressor to be compressed into the high-temperature high-pressure gaseous refrigerant and then is subjected to refrigeration cycle along the sequence. The refrigerant circulating in the refrigerating system exchanges heat with the air flowing in the room to cool or heat the room.

The throttling expansion device is arranged between the condenser and the evaporator, and is used for reducing the liquid refrigerant from the condensing pressure to the evaporating pressure, namely, the liquid refrigerant with medium temperature and high pressure from the condenser is throttled and reduced to be low-temperature low-pressure vaporific refrigerant which is easy to evaporate, and the low-temperature low-pressure vaporific refrigerant enters the evaporator, so that the refrigeration cycle process of heat release of the condenser and heat absorption of the evaporator is realized. The expansion device usually comprises an expansion valve and a capillary tube, wherein the capillary tube is the most widely used, and because the capillary tube is small in size, the refrigerant can not completely enter the capillary tube when entering the capillary tube from the condenser, so that the accumulation of the refrigerant can cause the increase of local pressure, and a refrigerating system can be damaged for a long time; in addition, the heat dissipation of a common air conditioner is insufficient in a high-temperature environment, so that the pressure of a condenser is too high, and the system is too negative.
