The principles of automotive air conditioning refrigeration: 1. When the automotive air conditioning is working, the low pressure in the refrigeration system is sucked in by the compressor and compressed into high pressure before being discharged to the condenser; 2. At the same time, the external air sucked in by the fan outside the vehicle flows through the condenser, taking away the heat released by the refrigerant, making the high-pressure liquid become high-pressure liquid; 3. The high-pressure liquid flows into the evaporator through throttling and depressurization, and evaporates at a corresponding pressure to absorb ambient heat. At the same time, it exchanges heat with the outdoor air between the evaporator fins, and sends the cooled gas after heat release to the vehicle interior. In this way, indoor and outdoor air continuously circulates and flows to achieve the purpose of refrigeration. The automotive air-conditioning refrigeration system consists of a compressor, a condenser, a liquid storage dryer, an expansion valve, an evaporator, and a blower. |
