CSA C22.2 NO 236-05 Document Information:
Title
Heating and Cooling Equipment
Canadian Standards Association
Publication Date:
Feb 1, 2005
Scope:
The requirements for heating and cooling equipment apply to the
following stationary equipment for
use in non-hazardous locations rated 7200 V or less, single- or
3-phase, and remote control
assemblies for such equipment:
(a) heat pumps for heating and cooling with or without factory- or
field-installed electric
resistance heaters, or hot water or steam heating coils;
(b) air conditioners for cooling with or without factory- or
field-installed electric resistance
heaters, or hot water or steam heating coils;
(c) cooling portion and associated components of combination heating
and cooling equipment
employing gas-, oil-, or gas-oil-fired heating means. However, the
requirements for the
construction and performance of the gas-, oil-, or gas-oil-fired
heating means, and their
associated components, are to conform to the particular standards
covering such heating equipment
and components;
(d) liquid chillers and compressor-evaporator or liquid chiller
assemblies intended for use with
remote condensers;
(e) condensing units intended for connection to a remote non-specified
evaporator and compressor
units intended for connection to a remote non-specified evaporator and
condenser;
(f) add-on heat pumps for comfort heating or heating and cooling;
(g) heat pump water heaters and refrigerant desuperheaters, and
packaged heat pump water heaters
consisting of a heat pump water heater and an associated storage tank;
(h) fan units and fan coil units for comfort heating and/or comfort
cooling; and
(i) room fan heater units, central heating furnaces, and similar fixed
electric space heating for
comfort heating.
The units referenced in Clause 1.1(g), self-contained heat pumps, and
air conditioners may be
cord-connected if they
(a) are for indoor use only;
(b) are rated 250 V or less, single phase, with a marked rating of 24
A or less; and
(c) comply with Clause 1.11.
A fan unit includes a motor-operated fan or blower and is intended to
be connected to a duct system
that supplies conditioned air for environmental heating and/or
cooling. Such a unit may have
air-controlled dampers, but does not include a factory-installed heat
exchanger or any other
integral heating or cooling means.
A fan coil unit includes a motor-operated fan or blower together with
a cooling coil or a heating
coil, or both. The fan or blower is intended to recirculate air, and
may introduce air from outside
of the heated or cooled space. The coil may be used for refrigerant
cooling, chilled water cooling,
hot water heating, steam heating, or combinations of these functions.
A fan coil unit is intended to be piped to a remote source of the
heating and/or cooling mediums. A
unit that includes an electric resistance heater is considered to be a
fan coil unit if a water or
refrigerant coil for comfort cooling and/or a water or steam coil for
comfort heating is provided
in the unit.
A room fan heater unit is intended for heating only, includes a
motor-operated fan or blower,
employs electric resistance heat as the only heat source, and is
intended to serve only one room or
space.
A fan coil unit or electric space heating equipment, as covered by
these requirements, may be
designed for free discharge of air to the room or may be provided with
means for duct connection.
A central warm air furnace is a heating appliance that consists of an
electric heating element or
elements with an air-circulating fan or blower, is provided with
appropriate integral operating and
temperature-limiting controls, and is housed in an enclosure designed
to be connected to ductwork
for the distribution of the heated air remote from the unit.
The units referenced in Clause 1.1 may consist of one or more
factory-made assemblies. If provided
in more than one assembly, the separate assemblies are to be used
together, and the requirements
are based on the use of matched assemblies. These requirements apply
to assemblies designed for
free discharge of air into the conditioned space, as well as those
which may be provided with means
for duct connection.
These requirements do not apply to add-on heat pump systems designed
to utilize the indoor fan
motor assembly of an installed furnace where
(a) the heat pump and furnace are intended to operate simultaneously
during heating operation
except as noted in the Exception to Clause 26.15; or
(b) the refrigerant coil is intended to be mounted upstream (return
air side) of the furnace.
These requirements apply to equipment designed to be used in
non-hazardous locations in accordance
with CSA C22.1, ANSI/NFPA No. 70, CSA B52, ANSI/ASHRAE 15, NFPA 90A,
and NFPA 90B.
Note: Requirements for the installation of units designed to be
connected to air duct systems are
also included in codes such as the BOCA Basic National Mechanical
Code, the ICC's Standard
Mechanical Code, and the ICC's Uniform Mechanical Code.
The values given in SI (metric) units are the standard. The values
given in parentheses are for
information only.
Units intended for connection to telecommunication equipment are to
have the appropriate assembly
containing such circuitry in accordance with CAN/CSA-C22.2 No. 226 and
UL 1459.
The following clauses of CAN/CSA-C22.2 No. 0 are superseded by the
requirements of this Standard:
(a) General Requirements, Clause 3, and Construction Details, Clause 4
(see Clauses 2 to 34 of this
Standard);
(b) Marking, Clause 5 (see Clauses 35 to 37 of this Standard); and
(c) Tests, Clause 6 (see Clauses 38 to 69 of this Standard).
The requirements in this Standard do not cover panel- or cable-type
radiant heating equipment,
electric boilers, baseboard heaters, air heaters, duct heaters, and
unit coolers for refrigeration
purposes, nor any other electric heating equipment or appliances that
are covered in separate,
individual Standards.
