1. The compressor
is responsible to pump the refrigerant through the system.
separates liquid refrigerant from vaporous refrigerant.
acts as a storage tank for liquid refrigerant
releases the heat from the controlled space to the outside air.
Service valves allow the technician to install a manifold gauge set for testing purposes and __________ of the refrigeration system
evacuation
recharging
purging
all of the above
The function of the condenser is:
To release the heat from the controlled space to the outside air.
To store liquid refrigerant until it is needed.
To filter the refrigerant and remove dirt and sludge.
To absorbed heat from the controlled space
The expansion valve
Creates low pressure in the condenser.
Creates high pressure in the evaporator.
Controls the pressure and boiling point in the condenser and evaporator.
All of the above
Which components divide the system between the low side and high side?
The compressor and expansion valve
The expansion valve and condenser
The condenser and evaporator
All of the above
What is the purpose of a heat exchanger?
To remove the heat from the controlled space.
To enable the refrigeration system to operate more efficiently.
To facilitate the condensing of the superheated refrigerant in the condenser section.
To cool the vaporous refrigerant returning to the compressor.
In regards to the thermostatic expansion valve, which force applied to the diaphragm causes the valve to open allowing refrigerant to pass?
Spring pressure.
Evaporator outlet pressure.
Compressor suction pressure.
Sensing bulb pressure.
The purpose of the evaporator is
To allow refrigerant to change states from gas to liquid before reaching the TXV
To aid in the cooling process of the drive engine
To allow the refrigerant to absorb heat from the controlled space.
To dry up any moisture that that may condense on the fins of the evaporator.
What is the function of the accumulator?
To enable the refrigeration system to operate more efficiently.
To allow the refrigerant to absorb heat from the controlled space.
To creates high pressure in the evaporator.
To separate liquid refrigerant from vaporous refrigerant before it enters the compressor.
Why do some truck-trailer refrigeration units use a suction pressure regulator?
To boost suction pressure thereby increasing compressor output.
To limit suction pressure protecting the drive engine from being overloaded.
To create high pressure in the evaporator.
To controls the pressure and boiling point in the condenser..
Both B and C are correct.
