Function and working principle of car condenser
car condenser is a part of the refrigeration system, belonging to a kind of heat exchanger. It can change gas or steam into liquid. and transfer heat in the pipe to the air near the pipe in a fast way.
The function of a car condenser is to heat and cool the high-temperature and high-pressure refrigerant vapor discharged from the compressor so that it condenses into the liquid high-pressure refrigerant. It can cool and liquefy the high-pressure and high-temperature refrigerant (gaseous refrigerant) sent from the compressor.
The working principle of a car condenser: the refrigerant enters the evaporator, the pressure decreases, and changes from a high-pressure gas to a low-pressure gas.
This process needs to absorb heat, so the surface temperature of the evaporator is very low, and then through the fan, the cold air can be blown out. Then it vaporizes through a capillary tube and evaporates in an evaporator.
The condenser and evaporator in automobile air conditioners are called heat exchangers. The performance of heat exchangers directly affects the refrigeration performance of automobile air conditioners. Its metal material consumption is large, its volume is large,
and its mass accounts for 50% – 70% of the total mass of the whole automobile air conditioning device.
The space it occupies directly affects the effective volume of the vehicle, so it is very difficult to arrange it. Therefore, it is very important to use an efficient heat exchanger.
The condensers and evaporators in auto air-cooning devices should match the compressor,
and should also adapt to the throttling expansion mechanism.
The working state of the condenser and evaporator directly affects the capacity of the refrigeration system (cooling capacity),
compressor power consumption and the economy of the whole air conditioning device.
The condenser is generally located in the front of the car, which makes it easy to adhere to various dust and sundries leaking into the gap of the engine hood.
For example, willow catkins in spring, attached to the condenser will lead to poor heat dissipation, directly leading to the air conditioning is not cool, so it should be cleaned regularly.
