Is responsible for circulating air in the passenger compartment?
A blower (fan)
blows air through the heater core and into the passenger compartment. A heater control valve controls coolant flow through the heater core, according to the temperature selected by the operator.
How does heat transfer through the air?
Convection
is the transfer of heat energy in a fluid. … Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air.
At which component in an air cycle cooling system does air undergo a pressure and temperature drop?

What is air conditioning system in automotive?
A car air conditioning system consists of a
compact version of the components of
the normal air conditioner that has an evaporator, compressor, condenser, expansion device, and a fan which are fitted in a car to provide air condition inside the passenger's compartment.
How does air conditioning transfer heat?
A cold liquid refrigerant absorbs heat from the hotter room in the evaporator, cooling the room down. The refrigerant then changes phase to a gas and is put through a compressor to increase its temperature. Refrigerant then passes through the condenser coils, transferring heat from the refrigerant to the outside air.
Which part of the system provides heat to the passenger compartment?
A heater core
is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air.
What does a heater control valve do?
