When checking the resistance of the compressor start winding, the technician's multimeter shows OL. This indicates that:
A) The winding is grounded. B) The winding has continuity and is good.
C) The winding is shorted. D) The winding is open.
[Ques. 2] The outdoor coil is the condenser in:
A) The heating cycle. B) The cooling cycle.
C) Neither the heating or cooling cycles. D) Both the cooling and heating cycles.
[Ques. 3] A desiccant wheel dehumidifier removes water from the air:
A) By passing the air over a refrigerated evaporator coil.
B) By spinning the air until water is removed by centrifugal force.
C) By passing the air through an open gas flame.
D) By absorbing it in a chemical desiccant.
[Ques. 4] The run winding on a compressor has a resistance of 0 . This indicates that:
A) The winding is open. B) The winding is shorted.
C) The winding has continuity and is good. D) The winding is grounded.
[Ques. 5] Why are the coils in an air-source heat pump referred to as the outdoor coil and indoor coil instead of the condenser and evaporator?
A) Because both the coils in a heat pump coils are identical.
B) Their function (evaporator or condenser) reverses when the unit changes from cooling to heating.
C) It can sometimes be difficult to determine the exact location of the coils.
D) Refrigerant does not evaporate or condense in a heat pump coil.
