How the evaporator work?

Install in case of automatic thermostat air conditioning (IHKA) or manual thermostat air conditioning (IHKR). It consists of a serpentine tube with a pressure fin.

The refrigerant flows through the serpentine tube. The fan blows the air to be cooled through the fins. To improve thermal conductivity, fins have a large surface area

In order to distribute the liquid refrigerant as uniformly as possible over the entire area of the evaporator, the evaporator is divided into a plurality of sub-flows of the same size.

With this structure, the efficiency of the evaporator can be increased. The branches of each refrigerant are collected at the ends of the serpentine tubes and then re-inhaled by the compressor

The role of the evaporator

Like the condenser, the evaporator is also a heat exchanger. It completes the main task of the air conditioning system is cooling air. Therefore it must absorb heat from the passing air

Air dried in this way can prevent fogging of the window glass

The evaporator absorbs the heat energy in the air from the outside and transmits it to the inside of the refrigerant.

Therefore, the evaporator and heat exchanger work. The most important factor here is the absorption of energy by the refrigerant from the liquid state to the gas state.

This process requires more heat, and heat is absorbed from the fins through which air flows.

The refrigerant evaporates at low pressure and in the case of blower heat inside the vehicle. Here the refrigerant becomes very cold. Pressure drops from the previous 10 to 20 bar to about 2 bar during spraying
