1)One ton of air conditioning is equivalent to:

2. Air-cooled equipment for heat rejection handle much smaller tons of capacity when compared to the tons of capacity for water-cooled heat rejection equipment
3. Since heat pumps can be used for heating and cooling purposes, typically one will see heat pumps with a SEER and a HSPF value.
4. A fuel oil                               is a boiler component that provides atomized fuel oil to the boiler.
5. A                           draft is a mechanical draft created by air pushed through the boiler firebox by a blower or fan located at the front of a boiler.
6. A hydronic heating system uses a boiler to heat water that is then transported through supply lines to spaces within a facility.
7. The flue gas, which is a by-product of the combustion occurring in boilers and furnaces, is non- toxic and may or may not be exhausted to the outdoors.
8. The vapor compression refrigeration cycle uses an absorbent such as lithium bromide
9. A heating plant for a large medical campus requires 22,000 MBH (1MBH = 1,000,000 btuh) of heating capacity. Which of the following pipe size and velocity in feet per second (fps) for the main would be needed if the plant is a 50 psig medium-pressure steam system?
10. Which of the following HVAC split systems has ductwork found above the furnace and cooling coil?
11. Which of the following would represent a common coefficient of performance value for an A/C system that uses the vapor compression cycle?
12. A split system for air conditioning separates the evaporator from the condensing unit.
13. An oversized cooling system will not only cost more, but can result in short cycling of the system
14. When a heat pump is in the cooling mode, the                               unit is the evaporator and the   unit is the condenser.
15. What does the compressor do in the vapor compression refrigeration system?
16. The flue gas, which is a by-product of the combustion occurring in boilers and furnaces, is non- toxic and may or may not be exhausted to the outdoors.
17. A hydronic heating system uses a boiler to heat water that is then transported through supply lines to spaces within a facility.
