For the refrigerators in the market at present, most of the refrigerators adopt a compressor for refrigeration, and cool air is provided for the refrigerators through circulation, so that the temperature requirements of all compartments are met.
The analysis of the working principle of a compression type refrigerator shows that the main refrigeration parts comprise a compressor, an evaporator, a condenser and a capillary tube, the refrigeration processes are compression, condensation, expansion and evaporation respectively, when the refrigerator works, a refrigerant is sucked by the compressor, the refrigerant is changed into a high-temperature high-pressure gaseous refrigerant after being sucked into the compressor through the compressor, the compressed refrigerant is conveyed into the condenser through a pipeline, the refrigerant starts to release heat after the condenser, the high-temperature high-pressure gaseous refrigerant is changed into a low-temperature high-pressure liquid refrigerant after being condensed, the refrigerant enters the capillary tube after being condensed, the pressure of the refrigerant is reduced through throttling and pressure reduction of the capillary tube, and finally the refrigerant enters the evaporator, the space in the evaporator is much wider than that of the capillary tube, the low-temperature low-pressure liquid refrigerant enters the evaporator and then rapidly absorbs heat and evaporates to finally become isothermal and isobaric gaseous refrigerant, and then the gaseous refrigerant is sucked and compressed by the compressor again to continue the refrigeration cycle. As the refrigerant evaporates to absorb heat, the temperature in the refrigerator decreases, and the cooling effect is finally achieved. Under the action of the compressor, the refrigerating system is driven, so that the refrigerator can work normally.
At present, the refrigeration systems and the working principles of the existing refrigerator and the air conditioner are compared, the situations of the existing refrigerator and the air conditioner are generally the same, but the refrigerator is different from the air conditioner in that the refrigerator can only provide the refrigeration effect and does not have the heating function.
