Car AC working has been discussed in this video.How car ac works is the basis of this video.Car AC System Parts
Automotive air-conditioning systems have a few key components. Listed below are the main parts and their roles:
Compressor
Power unit of the system that separates the low-pressure side from the high-pressure side Takes in low-pressure gas and compresses it into
high-temperature/high-pressure gas
Mounted to front of engine and driven by serpentine belt
Condenser
Reduces temperature of refrigerant while it maintains high pressure
Refrigerant changes from gaseous state to liquid state as it cools
Similar to the engine radiator, it uses forced air (fan or vehicle movement) to transfer heat
Mounted in front of vehicle, behind grill
Dryer
Removes water from the refrigerant using a desiccant (drying agent)
Has some system-filtering properties
Mounted on high-pressure side of system, between
condenser and metering device
Metering Device .Either expansion valve or fixed orifice tube
Lowers refrigerant pressure, which quickly drops
refrigerant temperature
Refrigerant is still in liquid form after leaving metering device
Mounted on high-pressure side of system, between dryer and firewall
Evaporator
Refrigerant changes back to gaseous state in the evaporator, causing a cooling effect
Cabin air is cooled and dried as it blows across the
evaporator
Only component mounted inside passenger
compartment, behind dashboard
Path and characteristics of refrigerant
Low-temperature/low-pressure refrigerant enters the
compressor (gas)
High-temperature/high-pressure
refrigerant leaves the
compressor (gas)
Refrigerant cools and converts to liquid in the condenser
Still under high pressure
Receiver/dryer removes water fromafter leaving metering device
Mounted on high-pressure side of system, between dryer and firewall
Evaporator
Refrigerant changes back to gaseous state in the evaporator, causing a cooling effect
Cabin air is cooled and dried as it blows across the
evaporator
Only component mounted inside passenger
compartment, behind dashboard
Path and characteristics of refrigerant
Low-temperature/low-pressure refrigerant enters the
compressor (gas)
refrigerant leaves the
High-temperature/high-pressure
compressor (gas)
Refrigerant cools and converts to liquid in the condenser .#ACnotworking
