Blower Motor
The blower motor is the fan that forces warm or cooled air through the dashboard vents depending on the system settings and the fan speed.
Compressor
The compressor is the key component of the HVAC system that generates high pressure before pumping refrigerant into the condenser, where it transforms from a gas to a liquid.
Compressor Clutch Assembly
The AC compressor clutch is needed to convert energy to make the compressor work. In simple electromagnetic, or electro-mechanical, clutches, they are operated by electricity but facilitate the mechanical transfer of torque
Condenser
The condenser is a heat exchanger.The condenser cools down the refrigerant (heated up by the compressor) and becomes a liquid by transferring its heat to the flow of ambient air passing through it.
Condenser Fan
A condenser fan is found near the condenser. It’s designed to remove heat from the refrigerant inside of the condenser.
Evaporator
The evaporator fan motor circulates air through the coils of the evaporator to remove heat from the circulating air. It is a component of the overall refrigeration system.
Expansion Valve
An expansion valve is a small orifice which throttles the flow of liquid refrigerant being pumped from the condenser to the evaporator
Hose
It carry the refrigerant from the compressor outlet to the receiver/drier so that it can be cooled and used to produce cold air for the cabin. It should withstand high pressure too.
On Off Switch and Electrical Control Panel
An electrical control panel is a metal box which contains important electrical devices that control and monitor a mechanical process.
Pressure Switch
The pressure switch keeps track of the high pressure level in the A/C loop and turns on or off the compressor based on two pressure limits. The cooling fan is controlled by a separate circuit that secures the condensation process by forcing air through the condenser.
Resistor
A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit.
Relay
Relays are utilised to start or stop the motor and compressor. We can’t run the compressor and motor directly because they are high voltage components. If we operate these high voltage components directly, they use a lot of electrical energy and fail quickly from routine use.
Thermostat
In order to maintain the desired temperature, a thermostat controls by turning heating or cooling units on or off or by adjusting the flow of a heat transfer fluid as necessary.
Recevier Dryer
A device containing a desiccant placed in series, usually in the liquid line, to absorb and hold excess moisture.
