Where does the low pressure liquid become a gas?
Evaporator
Condenser
TX valve
Compressor
In what state is the refrigerant when it exits the condenser?
High pressure gas
Low pressure gas
High pressure liquid
Low pressure liquid
What does a Thermal eXpansion Valve do?
Cleans, dries and filters the refrigerant
It controls the quantity of refrigerant entering the evaporator
Allows for an increase in pressure and temperature prior to entering the condenser
It acts as a safety device if the compressor is over pressuring the system
