Why Does the Car Air Conditioning Radiator Feel Hot to the Touch?
1 Answers
Car air conditioning radiators feel hot to the touch because the refrigerant in the car's air conditioning system is compressed by the compressor, resulting in a high-temperature state. When the high-temperature, high-pressure refrigerant gas enters the condenser, the pressure and temperature decrease, causing the refrigerant gas to condense into a liquid and release a significant amount of heat, which makes the radiator hot to the touch. Here is additional information: 1. Function: The condenser transforms the high-temperature, high-pressure gaseous refrigerant delivered by the compressor into a liquid refrigerant. The refrigerant dissipates heat in the condenser, leading to a change in its state. Therefore, the condenser acts as a heat exchanger, transferring the heat absorbed by the refrigerant inside the car to the outside atmosphere. 2. Structure: The condenser mainly consists of pipes and radiator fins, with one refrigerant inlet and one outlet. 3. Working Principle: The refrigerant enters the evaporator, where the pressure decreases, converting it from a high-pressure gas to a low-pressure gas. This process absorbs heat, causing the surface of the evaporator to become very cold. The fan then blows out the cooled air. The condenser cools the high-pressure, high-temperature refrigerant from the compressor into a high-pressure, low-temperature state, which then passes through the capillary tube to vaporize and enter the evaporator for evaporation.
