Most of the questions on this quiz are identical to those on Quiz 8.

1. The four main components of an absorption chiller are:

(a) condenser, compressor, absorber, evaporator

(b) condenser, evaporator, cooling tower, absorber

(c) condenser, generator, evaporator, absorber

(d) condenser, expansion valve, generator, absorber


2. The COP (coefficient of performance) of an absorption chiller is best described as:

(a) being substantially lower than the COP of a vapor compression chiller

(b) being substantially the same as the COP of a vapor compression chiller

(c) being substantially higher than the COP of a vapor compression chiller

(d) being of no concern, as the chiller uses no energy input


3. The acronym "HVAC" stands for:

(a) heating, ventilating, air quality, and cooling

(b) heating, ventilating, and air conditioning

(c) high-velocity air cooling

(d) high-volume air cooling


4. According to ASHRAE, an "air conditioning" system is expected to control:

(a) air temperature, relative humidity, air distribution, and air quality

(b) air temperature, mean radiant temperature, air speed, and relative humidity

(c) thermal comfort, indoor air quality, energy consumption, and occupant productivity

(d) heat flow through the building envelope, heat gains from people, and condensation


5. Name four of the five types of all-air HVAC systems:

(a) single zone (constant volume)

(b) terminal reheat (constant volume)

(c) multi-zone (constant volume)

(d) dual-duct (constant volume)

and also ..... variable air volume (VAV)


6. An induction unit (or cabinet) will be found:

(a) in an air-water HVAC system

(b) in a VAV all-air HVAC system

(c) as part of an evaporative cooling system

(d) as a key component of a typical flat-plate solar collector
