Product Picture:
Clutches:
The clutch is designed to connect the rotor pulley to the compressor input shaft when the field coil is energized. The clutch is used to transmit the power from the engine crankshaft to the compressor by means of a drive belt.
When the clutch is not engaged the compressor shaft does not rotate and refrigerant does not circulate the rotor pulley free wheels. The field coil is actually an electromagnet, once energized it draws the pressure plate towards it, locking the rotor pulley and the pressure plate together causing the compressor internals to turn, creating pressure and circulating refrigerant.
Evaporation:
Is the term used when enough heat is added to a liquid substance to change it into a vapor (gas). For example, when water is boiled.
This condition occurs within the A/C system.
Condensers:
The Condenser function is to act as a heat exchanger and allow heat to flow from the hot refrigerant to the cooler outside air.
R134a entering the condenser will be a high-pressure high temperature vapor. As the R134a vapor travels through the tubes of the condenser heat is given off to the cooler ambient air; the
refrigerant vapor condenses and changes to a liquid state.
At this point a large amount of heat is given off by the R134a. The refrigerant will now be a hot,high pressure liquid.
Key Components of a Car Air Conditioning System A typical car air conditioning system consists of several key components.
These include:
- Compressor: The compressor is the heart of the AC system. It compresses the refrigerant gas, increasing its temperature and pressure.
- Condenser: The condenser is positioned in front of the vehicle's radiator and acts as a heat exchanger. It cools down the compressed refrigerant, causing it to change from a gas to a liquid state.
- Expansion Valve: The expansion valve controls the flow of the refrigerant into the evaporator. It reduces the pressure and enables the refrigerant to rapidly expand, leading to a drop in temperature.
- Evaporator: The evaporator is typically located inside the dashboard or near the heating system. It absorbs heat from the cabin and cools the air by evaporating the liquid refrigerant.
- Receiver/Drier: The receiver/drier is responsible for removing moisture and contaminants from the refrigerant. It also stores the refrigerant until it is needed by the system. These key components work together to cool and dehumidify the air inside the car, providing a comfortable driving experience, especially in hot weather.
