The low side of a vapor compression cycle contains the:

• Condenser

• Compressor discharge line

• Evaporator

• Condenser and evaporator

The boiling point of refrigerant in the condenser is the same as:

• Evaporator temperature

• Compressor suction temperature

• Condensing temperature

• Condensing pressure

Of the following items the largest amount of heat removal in BTU’s for one pound of water is:

• Its sensible heat

• Its latent heat of fusion

• Its latent heat of vaporization

• Its latent heat of melting

If the evaporator in a vapor compression cycle is not cold enough, it can be made colder by:

• Raising the evaporator pressure

• Stopping the compressor temporarily

• Lowering the evaporator pressure

• Venting the refrigerant to the atmosphere

The purpose or the condenser in the vapor compression cycle is to:

• Save the refrigerant for re-use

• Reduce the superheated vapor to evaporator temperature

• Reduce the evaporator pressure

• Lower the condenser pressure

In the vapor compression cycle, the compressor:

• Heats the refrigerant vapor

• Reduces the evaporator pressure

• Compresses the refrigerant vapor

• All of the above

Water can be made to boil at 50 degrees by:

• Subcooling it to 50°F

• Reduce the pressure to 14.7 psi absolute

• Placing it under a high enough vacuum

• Lowering the pressure to atmospheric pressure
