Heating and Air Conditioning
Heating & Air Conditioning
Heat created by engine combustion is removed by a combination of antifreeze and water that circulates through channels within the engine. This hot liquid is transferred through a series of radiator hoses to the radiator.
As it passes into the radiator, the water flows through a device called a thermostat, which opens and closes to control the engines operating temperature.
The heater control valve inside the vehicle, regulates the amount of liquid that is bypassed into the heater core. The heater core has a fan installed behind it.
Once the engine has heated the liquid , a combination of the heater control valve and heater fan setting is used to regulate the interior temperature of the vehicle.
The compressor is a belt driven pump that is fastened to the engine. It is responsible for the compressing and the transferring refrigerant.
The A/C system is split into two “sides”, a high pressure side and a low pressure side.
The intake, or suction side, draws in the refrigerant gas from the outlet of the evaporator. In some cases it does this via the accumulator.
Once the refrigerant is drawn into the suction side, it is compressed and sent to the condenser, where it can then transfer the heat that is absorbed from the inside of the vehicle.
