QUESTIONS AND CORRECTLY WELL
DEFINED ANSWERS LATEST ALREADY
GRADED A+
Refrigerant sub cooling is a measurement of the difference
between: - ANSWERS-C. Condensing saturation temperature
and liquid line temperature
Two more accurately since the refrigerant temperature of
horizontal suction lines that are one and an 8th inch or
larger a thermostatic expansion valve sensing bulb that
should be mounted at which positions? - ANSWERS-D. Four
or 8 o'clock
What measurements would be needed to properly evaluate
a complaint of drafty operation with a heating system? -
ANSWERS-D. System TD, drop, and static pressure
,What is the effect on supply airflow using a PSC blower
motor when static pressure on the return is eliminated -
ANSWERS-B. Airflow will be increased
Drive cleats are typically installed where on rectangular
duct? - ANSWERS-D. On the shorter sides
A suction line accumulator should be used in a residential
heat pump only when recommended by the manufacturer
is: - ANSWERS-A. Long refrigerant lines increase system
charge over recommended maximum charge
A reason for cool air complaints when a heat pump is
operating in the heat cycle is: - ANSWERS-C. Excessive
supply air velocities
Suction line low pressure controls are often used in heat
pumps to protect the compressor: - ANSWERS-D. If suction
pressure drops too low and to detect a loss of charge
On a service call for a cooling problem with the heat pump
the inspection finds a liquid line that has condensation on it.
What is the most likely cause? - ANSWERS-B. Liquid line is
restricted
, The minimum circuit ampacity (MCA) listed on the data
plate of a package to heat pump is used to determine: -
ANSWERS-C. The maximum fuse or a circuit breaker size
In a low-voltage circuit, a corroded wire to terminal
connection ask in the circuit like a: - ANSWERS-C. Additional
resistor
In heating mode, a manifold gauge set is connected to the
vapor and liquid line service valves of a properly charge
system. What would the expected pressure be? - ANSWERS-
D. Vapor line will be higher and liquid line will be lower
Which of the following are temperatures used by
electronica demand defrost controls? - ANSWERS-A.
Outdoor coil and outdoor air
What could cause a customer to complain that their single
zoned home system in cooling mode feels sticky or damp? -
ANSWERS-C. Returns pulling in unconditioned air
