  1. 1How does the heating-cycle charge compensator aid the heating cycle?
    1. AIt makes the gas line cold.
    2. BIt raises the temperature of the refrigerant.
    3. CIt stores the unneeded refrigerant.
    4. DIt fills with hot air.
  2. 2How is the COP rating different from the HSPF?
    1. AHSPF takes data from multiple weather conditions.
    2. BOnly the HSPF measures heating and cooling units.
    3. COnly the COP measures defrost.
    4. DCOP takes data from multiple weather conditions.
  3. 3Because air source heat pumps circulate less refrigerant at low ambient temperatures, the refrigerant not being used is stored
    1. AIn a liquid receiver
    2. BIn the compressor crankcase
    3. CIn a suction accumulator or charge compensator
    4. DIn the metering device
  4. 4How is heat pump Coefficient of Performance, COP, calculated?
    1. ACOP is the ratio of heat output divided by heat input measured at one particular condition
    2. BCOP is a measure of heating BTUs per watt averaged for the entire heating season
    3. CCOP is a measure of heating BTUs per watt measured at one particular condition
    4. DCOP is the ratio of heat output divided by heat input averaged for the entire heating season
  5. 5How is heat pump Heating Seasonal Performance Factor, HSPF, calculated?
    1. AHSPF is the ratio of heat output divided by heat input measured at one particular condition.
    2. BHSPF is a measure of heating BTUs per watt measured at one particular condition
    3. CHSPF is the ratio of heat output divided by heat input averaged for the entire heating season
    4. DHSPF is a measure of heating BTUs per watt averaged for the entire heating season
  6. 6What prevents the refrigerant from flowing through the indoor metering device during the heating cycle?
    1. AThe outdoor check valve
    2. BThe heating shutoff valve
    3. CThe indoor check valve
    4. DThe reversing valve
  7. 7Heat pump A has a SEER rating of 16 and an HSPF rating of 7. Heat pump B has a SEER rating of 14 and an HSPF rating of 9. Which heat pump cools more efficiently?
    1. AHeat pump A
    2. BHeat pump B
    3. CThey are about the same heating efficiency by the time both the SEER and HSPF are considered
    4. DNeither the SEER nor the HSPF can determine which heat pump heats more efficiently
  8. 8What is the main difference between a heat pump and a fossil fuel furnace?
    1. AFossil fuel furnaces have been around longer.
    2. BFossil fuel furnaces are hotter.
    3. CHeat pumps are easier to install.
    4. DHeat pumps move heat instead of creating it.
  9. 9How can an air source heat pump heat when the outdoor temperature is cold?
    1. AThe friction of the air passing over the outdoor coil raises the temperature
    2. BAll molecules contain some heat until they reach absolute 0 (-460ºF)
    3. CAir source heat pumps only use the outdoor air in the cooling season
    4. DAll heating is accomplished with electrical resistance heaters, so the air temperature is irrelevant
  10. 10How can you lower the temperature at which evaporation takes place?
    1. AReduce the pressure on the low side of the system
    2. BRaise the pressure on the low side of the pump
    3. CDecrease the pressure on the high side of the pump
    4. DAdd more refrigerant into the pump
