SUCCESS GUARANTEED!
Charging a heat pump with refrigerant is best accomplished in the _______ mode.
A: Heating mode
B: Cooling mode
C: Defrost mode
D: Emergency heating mode - ANSWER B: Cooling mode
Heat pumps can provide both heating in the winter and cooling in the summer. In which mode is
the heat pump more efficient?
A: Heating mode
B: Cooling mode
C: Defrost mode
D: Emergency heating mode - ANSWER A: Heating mode
Which of the following components is exclusive to the heat pump?
,A: Condenser
B: Oil separator
C: Reversing valve
D: Accumulator - ANSWER C: Reversing valve
Which of the following airflow rates is the most reasonable for a heat pump system operating in
the heating cycle?
A: 200 cfm per ton
B: 300 cfm per ton
C: 400 cfm per ton
D: 450 cfm per ton - ANSWER D: 450 cfm per ton
During the heat pump's cooling cycle, the outdoor coil is utilized as a _________ while the
indoor coil is utilized as a____________.
A: Condenser, evaporator
B: Evaporator, condenser
C: Compressor, accumulator
, D: Accumulator, condenser - ANSWER A: Condenser, evaporator
Heat is present in winter outdoor air until the outside air ambient temperature reaches a low
temperature of:
A: 0 degrees F
B: 32 degrees F
C: 273 degrees F
D: -459 degrees F - ANSWER D: -459 degrees F
Technically this is true, but not practical. A heat pump is doing good to continue to work below
10 deg F unless specifically designed for lower temperatures.
The heat pump utilizes:
A: Two filter-driers with check valves
B: One bi-flow filter-drier
C: A single mono-flow filter-drier in the liquid line
D: Some use the bi-flow filter-drier and others use two filter-driers with check valves - ANSWER
D: Some use the bi-flow- filter-drier and others use two filter-driers with check valves
