International Mechanical Code Exam Questions With
Accurate Answers
ABSORPTION SYSTEM - accurate answers-A refrigerating system in which
refrigerant is pressurized by pumping a chemical solution of refrigerant in
absorbent, and then separated by the addition of heat in a generator,
condensed (to reject heat), expanded, evaporated (to provide refrigeration),
and reabsorbed in an absorber to repeat the cycle; the system can be single or
multiple effect, the latter using multiple stag
AIR - accurate answers-Air supplied to mechanical equipment and appliances
for combustion, ventilation, cooling and similar purposes. Standard air is air at
standard temperature and pressure, namely, 70ºF (21ºC) and 29.92 inches of
mercury (101.3 kPa).
AIR CONDITIONING - accurate answers-The treatment of air so as to control
simultaneously the temperature, humidity, cleanness and distribution of the
air to meet the requirements of a conditioned space
AIR-CONDITIONING SYSTEM - accurate answers-A system that consists of
heat exchangers, blowers, filters, supply, exhaust and return ducts, and shall
include any apparatus installed in connection therewith.
AIR DISPERSION SYSTEM - accurate answers-Any diffuser system designed to
both convey air within a room, space or area and diffuse air into that space
while operating under positive pressure. Systems are commonly constructed
of, but not limited to, fabric or plastic film.
AIR DISTRIBUTION SYSTEM - accurate answers-Any system of ducts, plenums
and air-handling equipment that circulates air within a space or spaces and
includes systems made up of one or more air-handling units.
AIR, EXHAUST - accurate answers-Air being removed from any space,
appliance or piece of equipment and conveyed directly to the atmosphere by
means of openings or ducts
AIR-HANDLING UNIT - accurate answers-A blower or fan used for the purpose
of distributing supply air to a room, space or area.
, APPLIANCE, EXISTING - accurate answers-Any appliance regulated by this
code that was legally installed prior to the effective date of this code, or for
which a permit to install has been issued.
APPLIANCE TYPE. - accurate answers-
High-heat appliance - accurate answers-Any appliance in which the products
of combustion at the point of entrance to the flue under normal operating
conditions have a temperature greater than 2,000ºF (1093ºC).
Low-heat appliance (residential appliance) - accurate answers-Any appliance
in which the products of combustion at the point of entrance to the flue under
normal operating conditions have a temperature of 1,000ºF (538ºC) or less.
Medium-heat appliance - accurate answers-Any appliance in which the
products of combustion at the point of entrance to the flue under normal
operating conditions have a temperature of more than 1,000ºF (538ºC), but
not greater than 2,000ºF (1093ºC).
APPLIANCE, VENTED - accurate answers-An appliance designed and installed
in such a manner that all of the products of combustion are conveyed directly
from the appliance to the outdoor atmosphere through an approved chimney
or vent system.
BREATHING ZONE - accurate answers-The region within an occupied space
between planes 3 and 72 inches (76 and 1829 mm) above the floor and more
than 2 feet (610 mm) from the walls of the space or from fixed air-
conditioning equipment.
COMMERCIAL COOKING RECIRCULATING SYSTEM - accurate answers-Self-
contained system consisting of the exhaust hood, the cooking equipment, the
filters and the fire suppression system. The system is designed to capture
cooking vapors and residues generated from commercial cooking equipment.
The system removes contaminants from the exhaust air and recirculates the
air to the space from which it was withdrawn
