NATE HEAT PUMP UPDATED EXAM PAPER
QUESTIONS AND ANSWERS SURE A+
✔✔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 - ✔✔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 -
✔✔D: Some use the bi-flow- filter-drier and others use two filter-driers with check valves
✔✔The correct way to size a heat pump is to perform both heating and cooling load
calculations and select the heat pump size by:
A: Adding the heating load and cooling loads
B: Subtracting the smaller load from the larger load
C: Using the heating load to size the system
D: Using the cooling load to size the system - ✔✔D: Using the cooling load to size the
system
✔✔Auxiliary electric heat is necessary because:
A: It provides heat for the home during defrosts
B: It provides heat for the home in the event of a heat pump failure
C: It provides heat for the home if the heat pump is unable to meet the demand for heat
D: All of the above - ✔✔D: All of the above
✔✔Reading a voltage across the contacts of the outdoor thermostat means:
A: The thermostat contacts are closed
B: The thermostat contacts are open
C: The thermostat contacts are stuck
D: The thermostat contacts are working correctly - ✔✔B: The thermostat contacts are
open
✔✔Which of the following is not a type of heat pump?
A: Ground to air
B: Air to air
C: Water to air
