Spring 2001 / Grondzik / 5 April 2001

1. The two most common types of air-water HVAC systems are:

(a) the induction and the fan-coil with supplemental air systems

(b) the VAV and the multi-zone systems

(c) the photovoltaic and the photosynthetic systems

(d) the baseboard radiation and the modular heat pump systems


2. There are several commonly used piping arrangements for air-water and all-water HVAC systems. These are:

(a) the one-pipe, three-pipe, and five-pipe arrangements

(b) the horizontal and vertical pipe arrangements

(c) the two-pipe, three-pipe, and four-pipe arrangements ..... supply/return; supply + supply / return; supply/return + supply/return

(d) the big-pipe and small-pipe arrangements


3. The biggest drawback to use of an all-water HVAC system is:

(a) the difficulty encountered in running heating/cooling distribution throughout a building

(b) the difficulty in providing adequate indoor air quality with this type system

(c) the fact that this type of system needs a central heat source and central cool source

(d) none -- this is a proven problem-free system


4. A fan-coil unit will be found in:

(a) all five of the all-air HVAC systems

(b) each and every one of the air-water HVAC systems

(c) some air-water and all-water HVAC systems ..... specifically, fan-coil systems with (air-water) and without (all-water) supplemental air

(d) some local HVAC systems


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. A "photovoltaic" system converts solar radiation to:

(a) chemical energy

(b) thermal energy (heat)

(c) electrical energy .... "volt"

(d) long-wave radiation
