In the automotive air-conditioning system, the transformation from liquid to gas begins when the air from the passenger compartment passes over the coils and fins.

______ currents from the heated air in the passenger compartment flow over an evaporator core of refrigerant, causing a conduction of heat through the metal coils of the evaporator.

Fixed orifice tube automotive air-conditioning systems use a(n) to ensure that a pure gas is delivered to the compressor.

Automotive air-conditioning is federally regulated by _______.

The function of air-conditioning in the HVAC system is to .

, a member of the CFC family of gases, was the first common refrigerant to be used in an automotive air conditioner.

The older refrigerant systems that used typically used mineral oil as a lubricant.

The acts as a low-pressure safety switch for the air-conditioning system.

In a fixed orifice tube air-conditioning system, the low-pressure cycling switch is typically installed on the low-pressure line or on the:

The heater core is located inside the passenger compartment in a plastic box with the air-conditioning _____?

With the use of , maintaining vaporization and condensing points at normal ambient temperatures is simply done by raising or reducing the pressure of the refrigerant.

The key shared components of the engine cooling and cabin heating systems include all of the following EXCEPT:

In the automotive refrigerant system, low-pressure liquid leaves the metering device and travels into the _____ in the passenger compartment.

If the velocity of the liquid rises, the pressure of the liquid must drop according to the principle.

The automotive air-conditioning cycle starts with the .

As the engine heats up from the process of burning fuel to create power, the coolant in the engine is also heated, reaching operating temperatures of approximately __________.

The first use of air heated from _____ to warm the passenger compartment dates from the late 1920s.

In an orifice tube style air-conditioning system, the accumulator is located between the:

________ is the process of transferring heat through matter by the movement of heat energy through solids, from one particle to another.

The ______ is installed on the low-pressure refrigerant line or the accumulator to turn the air-conditioning clutch on and off at certain pressures.

Heat always travels:

Mineral oil is clear to light yellow, and PAG oil is usually a light color.

What is a common coolant mixture ratio of coolant to water in the average vehicle?

made it possible for air-conditioning systems to be used by consumers with no apparent harm, unlike the ammonia systems.
