Car-Air-Conditioning



The comfort making machine!

Car-air-conditioning can be found in the cars that are cruising the highways today. They cool the passenger's compartment so that we can drive comfortably. Imagine if your air conditioner breaks down on a hot summer day, or on a rainy day, you will find it almost impossible to drive!

When we are driving a car, we close our windows and turn on the air conditioner. We are being shielded from the dust, dirt, exhaust fumes, and pollution from factories. The air conditioner filters the air inside the passenger compartment, dehumidifies it, and cooling it according to the temperature we set on the thermostat.

The air conditioner filters the air inside the passenger compartment, dehumidifies it, and cooling it according to the temperature we set on the thermostat. To understand how the air conditioners work, we must understand the refrigeration cycle.

The Basic Refrigeration Cycle

Refrigerant gas from Evaporator enters the compressor it is being compressed at high speed, and the high-temperature, high pressure gas refrigerant enters the condenser unit.

Heat is dissipated into the atmosphere, this process turns the gas refrigerant into liquid refrigerant.

The liquid refrigerant passes through a receiver/dryer where the moisture, dirt and small iron particles are removed from the refrigerant.

Then it enters the expansion valve, where the volume of the liquid refrigerant is being controlled, and enters into the evaporator.

Heat inside the passenger compartment is being absorbed and the refrigerant turns into gas. It now returns to the compressor where the whole cycle repeats itself again.

When you are on the road, it is always a good idea that you carry a set of basic tools. Provide periodic preventive maintenance to you vehicle and to the air conditioner components. It might take some work, but the return is a trouble-free and cool driving!
