Refrigeration is cooling the air and removing the humidity in it. The refrigerator in your residence, the air conditioner in your office, home or car; all operate in the same way. The functioning principle is evaporation and condensation.

To change the principles of evaporation and condensation into refrigeration system you have a series of components that are connected by tubing and hoses. The six basic components required for a refrigeration system are the compressor, condenser, receiver drier, thermostatic expansion valve, the evaporator and the refrigerant. The refrigerant is a liquid that is competent of vaporizing at a low temperature.

This is how the refrigeration system and the components work.

- The energy unit of the refrigeration system is the compressor. The compressor pumps refrigerant vapor in high pressure and heat to the condenser.

- The condenser converts the high-pressure refrigerant vapor to liquid by eradicating the heat from the refrigerant.

- Refrigerant travels to the drier. This appliance works as storage tank for the liquid refrigerant and also removes moisture from ...
... the refrigerant. Moisture in the system can freeze and cause blockage in the system.

- Continuous compression pressurizes the system forcing the liquid refrigerant under high pressure to circulate from the receiver drier to the thermostatic expansion valve. Pressure from the liquid refrigerant is removed by the valve helping it to expand and convert to refrigerant vapor in the evaporator.

- Like the condenser, the evaporator is a device that have tubes and fins. The pressuried refrigerant vaporizes in the evaporator and absorbs heat and the air cools. This completes the process of primary refrigeration, thereby inducing cooling in your refrigerator or in your space or car by an air conditioner.

- The overall process of another refrigeration cycle starts when the heat laden, low-pressure refrigerant vapor is drawn into the compressor.

Thus, by continuously circulating, evaporating and condensing a fixed supply of refrigerant in a closed system accomplish mechanical refrigeration.

Incase of a malfunction the first step should be to determine the cause. Analyzing completely the system and considering the intended function of each section can do this. It is vital to deduce the cause.

The refrigerants used for refrigeration were synthetic refrigerants based generally on chlorofluocarbon (CFC) chemical. This is safe for home and commercial organizations. During the late 1920s, hydro chlorofluorocarbon (HCFC) and hydro fluorocarbon (HFC) refrigerants were formulated and was considered less harmful than the commonly used methyl formate, ammonia, methyl chloride and sulphur dioxide.
