How does the car air conditioning and heating system works

Most of us have become accustomed to air conditioning made available to the comfort of our vehicles and heating. During the cold months, hot air keeps the cold at bay. In making the warmer months, the A / C generates cool air to the driving experience more comfortable.

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

The technology used to design a vehicle heating and A / C has evolved in recent decades. But problems can occur. This article explains how different components work together to ensure that the unit is as comfortable as possible. It will then look in places that you can see the road.

The task of the compressor

On the side of the engine is a component called the compressor. There is a pump that the responsibility for the compression of refrigerants (R-134a, freon, etc.) and sending it to another component called a capacitor (see below). To meet this responsibility, provide for the low-pressure gas compressor from the evaporator. The compressor compresses the gas – heating in the process – before passing through the system.

The condenser and expansion valve

A / C system condenser cooling seems to be in YourRadiator> System. He also works in a similar way. Once the high temperature, pressurized gas from the compressor reaches the condenser, passes through a process that is removed from the heat of him. During this process, the refrigerant gas is converted into liquid under pressure before leaving the condenser on the way to the expansion valve.

The expansion valve regulates the amount of refrigerant to the evaporator is reached (see below). If you change the temperatureControl in a vehicle cab, set this component. The higher the temperature, the less refrigerant, is passed to the evaporator.

Evaporator

Your air conditioner's evaporator tasks. First, is accused of removing heat from inside the cab of your car. Secondly, it removes moisture from the air and let them pass through the slits.

At present, the liquid refrigerant fromThe expansion valve, removed much of its pressure. Enters the evaporator where it is dehumidified before publication. The refrigerant then leaves the evaporator and travels back to the compressor to begin its journey. Meanwhile, the cold air is blown through the air vents of your car with a blower.

Potential problems that develop

The most common problems experienced drivers and their cars with heating and air conditioning are the lack of cold air, intermittentCooling capacity and noise and smell. The lack of cold air is usually a lack of refrigerant. This means that there is a leak from the seals and hoses in some part of a C /. Where losses such equipment is best left to an experienced professional who demands the '.

Intermittent cooling is often an obstacle caused by moisture. The finding of obstruction, similar escape in search of a cooler, difficult if you have access to the rightDiagnostic equipment. The problem can also be an electrical fault which prevents the compressor clutch engagement can be triggered. If you do not engage the clutch, the compressor will not.

When you hear the auto A / C makes more noise than a mechanical control of the compressor. There is a high probability of component failure, and must be replaced. If you smell a musty smell from the vents, mold has developed probably the evaporator. This is donebecause the moisture collects on the evaporator surface (remember that the component removes the coolant). Do not ignore the smell. Have the form fixed.

The air conditioning and heating of the vehicle should operate for years without incident. In case of problems, but the repairs are the best mechanics next to one.

As heating and air conditioning in cars Works

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.
