,
, Which statement is true? (pg. 1-3)
A) The higher the 'k' factor, the greater the thermal conductivity
B) The lower the 'k' factor, the greater the thermal conductivity
C) The higher the 'k' factor, the lower the thermal conductivity
D) The 'k' factor is not associated with thermal conductivity A) The higher the 'k' factor, the greater
the thermal conductivity
Optimum 'U' factor for the given material that the heat exchanger is made of results when? (pg. 1-7/8)
A) There is no impeding substance such as ice, dirt, or oil on the surfaces of the heat exchanger tubes
B) Maximum airflow across the evaporator is achieved
C) The system is operating with the design recirculation low
D) The system is maintaining temperature A) There is no impeding substance such as ice, dirt, or
oil on the surfaces of the heat exchanger tubes
When air flow is decreased across a heat exchange surface, cooling capacity is? (pg. 1-10)
A) Reduced
B) Increased
C) Not changed because area is not changed
D) Not changed because evaporator temperature is not changed A) Reduced
Centrifugal fans have an advantage over propeller fans in that they ______________ than prop fans?
(pg. 1-12)
A) Require less physical space
B) Consume more hp per CFM of air moved
C) Are quieter
D) Have fewer components to maintain C) Are quieter
Which of the following factors listed below does not affect heat transfer?
(pg. 1-2)
A) Temperature Difference
B) Surface Area
C) Thermal Conductivity
D) Density D) Density
An example of a poor conductor of heat is? (pg. 1-3)
, A) Aluminum Tubing
B) Schedule 40 Steel Pipe
C) Wood
D) Water C) Wood
Thermal conductivity ('K') is? (pg. 1-3)
A) Exactly the same for any metal
B) The number of BTU's that will pass in 1 hour through a material 1" thick with an area of 1 sq. ft. if the
temperature difference from one side to the other is 1°F
C) A measure of the total energy (heat content) per pound of refrigerant measured in BTU's
D) A relationship between heat and temperature that is useful in determining discharge temperatures. It
is heat moved into or out of the process, divided by the absolute temperature in BTU's/pound/R B) The
number of BTU's that will pass in 1 hour through a material 1" thick with an area of 1 sq. ft. if the
temperature difference from one side to the other is 1°F

(pg. 1-7)
A) Water
B) Oil
C) Frost
D) Dirt A) Water
The operating engineer? (pg. 1-7)
A) Cannot change the 'k' factor of the metal but has some control of the overall 'U' factor for the
evaporator as a unit
B) Can increase 'k' factor by increasing the air velocity over the evaporator and has some control of the
overall 'U' factor for the evaporator as a unit
C) Should allow frost to collect on the evaporator increase 'k' factor
D) Can increase 'k' factor by starting another compressor A) Cannot change the 'k' factor of the
metal but has some control of the overall 'U' factor for the evaporator as a unit
The limiting factor of an evaporator's capacity that the operator cannot control is? (pg. 1-7)
A) Suction Temperature
B) Suction Pressure
C) Evaporator Size
