The principle of refrigeration unit refers to the principle of air conditioning refrigeration operation. After the air conditioner is energized, the low-pressure vapor of the refrigerant in the refrigeration system is sucked in by the compressor and compressed into high-pressure vapor before being discharged to the condenser. The indoor air continuously circulates to achieve the purpose of lowering the temperature.
The outdoor air sucked by the axial flow fan flows through the condenser, taking away the heat released by the refrigerant, and condensing the high-pressure refrigerant vapor into a high-pressure liquid. The high-pressure liquid is sprayed into the evaporator after passing through the filter and the throttling mechanism, and evaporates under the corresponding low pressure to absorb the surrounding heat. At the same time, the cross-flow fan keeps air entering the fins of the evaporator for heat exchange, and sends the cooled air to the room after the heat is released.
