1)One ton of air conditioning is equivalent to:

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
Since heat pumps can be used for heating and cooling purposes, typically one will see heat pumps with a SEER and a HSPF value.
A fuel oil is a boiler component that provides atomized fuel oil to the boiler.
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.
A hydronic heating system uses a boiler to heat water that is then transported through supply lines to spaces within a facility.
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.
The vapor compression refrigeration cycle uses an absorbent such as lithium bromide
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?
Which of the following HVAC split systems has ductwork found above the furnace and cooling coil?
Which of the following would represent a common coefficient of performance value for an A/C system that uses the vapor compression cycle?
A split system for air conditioning separates the evaporator from the condensing unit.
An oversized cooling system will not only cost more, but can result in short cycling of the system
When a heat pump is in the cooling mode, the unit is the evaporator and the unit is the condenser.
What does the compressor do in the vapor compression refrigeration system?
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.
A hydronic heating system uses a boiler to heat water that is then transported through supply lines to spaces within a facility.

The refrigeration cycle uses a negative expansion valve to obtain either heating or cooling from a heat pump
Which type of fan is used for air handling and return air?
Minute pressure changes can be expressed in of water column.
Inches
Single zone VAV systems are more energy efficient than CV terminal reheat systems
The dust spot efficiency test used for rating and testing air filters uses atmospheric dust that is passed through the filter and the discoloration of the dust passing through the filter is observed.
This phenomenon occurs when an air stream of conditioned air moves through a space
A constant volume HVAC system uses which of the following principles to provide comfort to a space?
In a multiple-zone VAV system, a master thermostat is used to control the temperature of the entire building.
A reverse return HVAC piping system provides the first unit in the system with the longest supply and the shortest return piping
Water pressure can be expressed in feet of head or in pounds per square inch
When sizing rectangular ductwork, which of the following dimensions should be stated first?
Registers are composed of two components - Dampers & grilles.
A duct is sized to allow the required amount of air for proper heating or cooling to flow to each building space.
