What role does the condenser play in the compressor?

There is no condenser in the compressor, the condenser, like the compressor, is one of the four major components of the refrigeration system.

First, condenser is an element of the air conditioning system that transfers heat from the tubes, in a very fast manner, to the air near the tubes, which most cars place in front of the tank. A device that converts a gas or vapor into a liquid.

Second, the power plant to use many condensers to make the turbine exhaust vapor condensation; in the refrigeration plant with condensers to condense ammonia and freon and so on the cooling vapor. Petrochemical industry with condensers to make hydrocarbons and other chemical vapor condensation.

Third, in the distillation process, the vapor into a liquid device called condenser. All condensers operate by taking the heat away from the gas or vapor.

Fourth, the compressor inhales from the evaporator out of the lower pressure of the workpiece steam, so that the pressure rises sent to the condenser, in the condenser condensed into a higher pressure liquid, throttled by the throttle valve throttle, after becoming a lower pressure liquid, sent to the evaporator, the evaporator in the evaporator to absorb heat and evaporation and become a lower pressure of steam, thus completing the refrigeration cycle.

Fifth, for some applications, the gas must pass through a long tube (usually coiled into a solenoid), in order to let the heat dissipate into the surrounding air, copper and other heat-conducting metals are often used to transport the vapor. In order to improve the efficiency of the condenser is often attached to the pipe heat sink to accelerate heat dissipation.

Sixth, the heat sink is made of good heat-conducting metal plate. This type of condenser generally also need to use the fan to force the air through the heat sink and take the heat tape away. General refrigeration principle of refrigeration compressor is the role of the lower pressure steam compressed into a higher pressure steam, so that the volume of steam to reduce the pressure increases.

Role and working principle of condenser

The condenser, as the name suggests, is the component that cools the refrigerant and condenses it into liquid refrigerant!

Its most important role is to complete the heat exchange of the refrigeration system. Condenser is a car air conditioning in the cooling device, the compressor compression process of the heat of the refrigerant dispersed to the outside of the car space, so that the compressor out of the high-temperature high-pressure gas into a medium-temperature high-pressure liquid.

Does that mean: the heat absorption of the evaporator is the heat release of the condenser?

Not also! In fact, the condenser heat release = evaporator heat absorption + compressor operation heat. Inside the compressor is rotating, the relative friction movement of the components will produce heat!

So: the condenser heat is greater than the evaporator heat absorption!

Automobile air conditioning heat exchanger is currently the main form of tube sheet type, tube belt type, parallel flow type three.

The structure of the condenser from the tube sheet type to the tube belt type development, and mainly to the parallel flow type development. The internal structure of the cascade and parallel flow type is constantly developing again to facilitate further improvement of heat transfer efficiency and weight reduction, parallel flow type condenser from the unit parallel flow type development into multiple parallel flow type. As a result of the measures taken to reduce the thickness of the tube sheet, increase the tube ribs, fin openings, change the shape of the fins and the opening angle, increase the fin heat dissipation area, strengthen the heat exchange efficiency of the gas side and liquid side.

How condensers work

The condenser is used to release heat. The refrigerant is compressed by the compressor to the condenser, which has a capillary tube at the end. The capillary tube creates resistance so that the gaseous refrigerant compressed by the compressor liquefies and achieves the exothermic effect. The condenser is high pressure and will only be hot. And the evaporator will be cold, the condenser of liquid refrigerant through the capillary tube to reach the evaporator will be quickly vaporized, evaporation and heat absorption, and to achieve the cooling effect. Cold and heat is such a continuous cycle of generation!

So, what are the common condenser failures?

Leakage, clogging, poor heat dissipation and so on.

Leaks go without saying, sludge there is a leak there.

For a clogged condenser failure, it's usually not very common. In some older vehicles, as the air conditioning system becomes more and more contaminated, the contaminants may build up in the corners of the condenser, creating a damping hole similar to a throttle orifice tube, which blocks the flow of refrigerant.

Judgment of such problems, it is very simple, is in accordance with the direction of flow of the condenser, from top to bottom step by step measurement of each layer of the condenser asked the temperature; normal condenser from the upper layer to the lower layer of the temperature is gradually decreasing from high to low, there should not be a significant change in temperature; if we find that there is a significant change in the temperature between the two layers, then it should be the internal clogging, the formation of the throttling up.

For the cooling efficacy of the condenser, it is not necessarily the condenser itself that is dirty, it is likely that the tank is dirty resulting in poor cooling. Our common vehicles, generally will be arranged in front of the condenser in the water tank, air dirty many cases will accumulate between the condenser and the water tank, especially in the front of the water tank will be deposited in a large number of flocculent clogging, affecting the heat dissipation of airflow. This leads to poor cooling of the condenser and poor cooling effect of the air conditioning system.
