Which refrigeration system is used in cars?
In most cars that are on the road today, R134a refrigerant makes the A/C system blow cold on hot days. Selected for its low flammability and safety, as well as because it’s kinder to the environment, almost every car built since 1994 is equipped with R134 refrigerant.
What is automotive AC system?
Car air conditioning is a system within your car that allows you to cool the interior air of the vehicle in hot weather, providing for a cooler environment for the occupants. Your car’s air conditioning system is made up of three main parts – the compressor, the condenser and the evaporator.
Is a car AC system a closed system?
An A/C system is a closed system, and if there are no problems, coolant is not consumed by the vehicle, nor does it escape. Problems with your car’s A/C may also signify compressor on condenser troubles that require professional repair. Auto A/Cs are complex systems, and there are numerous things that can go wrong.
Which cycle is used in car air conditioning?
Liquid (refrigerant) is cycled throughout a sealed air conditioning system in a repeated process of vaporization (evaporation), liquefaction, and re-vaporization. It is necessary for a gas to give off heat to liquefy (condense).
What are the types of refrigerant?
Types of Refrigerants
- Chlorofluorocarbons (CFCs), including R12. This is known to contribute to the greenhouse gas effect.
- Hydrochlorofluorocarbons (HCFCs), including R22.
- Hydrofluorocarbons (HFCs), including R410A and R134.
Which gas is used in AC in car?

What is an refrigerant?
A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again.
What are the two types of automotive air conditioning systems?
The two different types of air conditioning systems
- The expansion valve system.
- The fixed orifice tube system.
Where is refrigerant in air conditioner?
copper coils
Air conditioners contain refrigerant inside copper coils. As refrigerant absorbs heat from indoor air, it transitions from a low-pressure gas to a high-pressure liquid. Air conditioning components send the refrigerant outside where a fan blows hot air over the coils and exhausts it to the exterior.
What is AC compressor in car?
The compressor is the power unit of the air-conditioning system that puts the refrigerant under high pressure before it pumps it into the condenser, where it changes from a gas to a liquid. On most cars, A/C compressors are driven by an engine-accessory belt.
What type of gas is used in AC?
Freon
Freon is a non-combustible gas that is used as a refrigerant in air conditioning applications. This freon undergoes an evaporation process over and over again to help produce cool air that can be circulated throughout your AC system.
What is mechanical refrigeration?
Definition of mechanical refrigeration : the abstraction of heat by means of a working substance subjected to refrigerating thermodynamic cycles in which the energy is supplied by a mechanical compressor : cooling produced by a machine instead of by melting ice.
What is automotive air conditioning system?
As like all air conditioning system the aim of automotive air conditioning is to control the temperature and humidity of the atmospheric air and circulate the same in the automobile. The automotive air conditioning system consists of a refrigeration system, air circulation, and distribution system and a control system.
What type of refrigerant is used in air conditioning systems?
The refrigerant gas used in most vehicles is commonly known as Freon or R134A. Prior to 1994 R12 was used in air conditioning systems, but was discontinued due to the highly polluting nature of the gas. The ability of the refrigerant to change its physical properties as it is compressed, cooled and metered is what makes the AC system work.
How does a car refrigerant system work?
The compressor and condenser push the refrigerant gas through the system, changing temperature and drawing warm air from the cabin while pumping cool air inside. But there’s a catch: the refrigerant in your car is a volatile chemical.
How does a car a/C system work?
The compressor and condenser push the refrigerant gas through the system, changing temperature and drawing warm air from the cabin while pumping cool air inside. But there’s a catch: the refrigerant in your car is a volatile chemical. Special machinery is required to service a car’s A/C system, so that old gasses can be captured and recycled.
