NATE/ICE Heat Pumps
What is the purpose of the reversing valve on a air to air heat pump?
A. it reverses the direction of the compressor
B. it changes the flow of refrigerant, making the outdoor coil the condenser during the winter
months
C. it changes the flow of refrigerant, making the indoor coil the condenser during the winter
months
D. it changes the flow of refrigerant, making the indoor coil the condenser during the summer
months - ANSC. it changes the flow of refrigerant, making the indoor coil the condenser during
the winter months

system for the reversing valve to operate properly?
A. 25 psig
B. 50 psig
C. 75 psig
D. 100 psig - ANSC. 75 psig
where are the check valves located on a air to air heat pump?
