As heating and air conditioning in cars Works

June 5, 2010

Most of us have become accustomed to the system of comfort available to the vehicles of our heating and air conditioning. During the colder months, cold air continues to warm in the bay. In making the warmer months, the A / C generates fresh air driving more comfortable.

Like most auto parts and systems, heating and air conditioning, without our thinking about them. Unfortunately, they suffer wear and tear. You can not break for a number of reasons, anddo their respective work.

The technology used to connect the vehicle heating and A / C was evolved in design. But problems can occur at any time. In this article you will discover how different components work together to ensure the unit is as comfortable as possible. We will then look at a couple of problems can occur down the road.

The work of the compressor

On the side of your car engine is a component called the compressor. There is a pump which is responsible for compression of refrigerant (R-134a, Freon, etc.) and sends it to another component called a capacitor (described below). To fulfill these responsibilities, provide low pressure gas compression on one side of the evaporator. The pressure of the compressor gas – heating in the process – before the system.

The condenser and expansion valve

A / C system seems like your condenser to your coolingradiator> System. He also works similarly. Once the high temperature, pressurized gas from the compressor through the condenser, it undergoes a process that removes the heat from it. During this process, the pressurized liquid refrigerant in the condenser becomes the first on the road to the expansion valve leaves.

The expansion valve regulates the amount of refrigerant to the evaporator (see below) reaches. If you change the temperature,Control in the cab, set this component. The higher the set temperature, less refrigerant passing through the evaporator.

Vaporizer

Your air conditioner is the evaporator has a few tasks. First, is responsible for removing the heat in the cabin of your car. Secondly, it removes moisture from the air, going to leave through the vents.

Over time, the liquid refrigerant from theexpansion valve, has squandered much of its pressure. It enters the evaporator where it is dried before its publication. The refrigerant leaves the evaporator and then travels back to the compressor to begin its journey. Meanwhile, cold air is blown through vents in the car with an engine fan.

Potential problems that develop

The most common problems experienced drivers with their cars and heating air conditioning include the lack of cold air, intermittentCooling and noise and smell. The lack of cold air is usually due to a lack of refrigerant. This means there is an escape from the seals and hoses, but somewhere in the A / C system leaks Where such equipment is best left to an experienced professional who has requested the extension.

Intermittent cooling is often due to obstruction by moisture. Determine the obstacle, similar to finding a loss of coolant can be a challenge if you log on to the rightdiagnostic devices. The problem can also be an electrical fault which prevents the compressor clutch discourage triggered. When the clutch will not engage, the compressor will not work.

When you hear your car A / C makes more noise, a mechanical control of the compressor. There is a high probability of component failure, and must be replaced. If you smell a musty odor from the mouth, the mold has probably grown in the evaporator. This is donebecause moisture accumulates on the surface of the evaporator (remember that an element of the liquid refrigerant dehumidification). Do not ignore the smell. They removed the form.

The heating and air conditioning in the vehicle should work without problems for years. In case of problems, but repairs are best left a mechanic.
