Product Details
This is the third edition of the Standard for Packaged Terminal Air-Conditioners and Heat Pumps, jointly published by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI 310/380-2014) and CSA Group (CSA C744-14). It supersedes the previous edition of this joint Standard published in 2004.
This Standard, which applies to factory-manufactured residential, commercial, and industrial packaged terminal air-conditioners and heat pumps, provides requirements for rating, performance, and tests. Separate requirements are provided for Canadian jurisdictions for rating, performance, and tests (see Clause 10). These separate requirements reference CSA Group Standards.
The publishers of this Standard wish to express their appreciation for the financial support of Natural Resources Canada, Manitoba Hydro, Ontario Ministry of Energy, CEA, and Ontario Power Authority.
Introduction
The purpose of this Standard is to establish the following for packaged terminal air-conditioner and heat pump equipment:
a) test requirements;
b) rating requirements;
c) minimum data requirements for published ratings;
d) operating requirements;
e) marking and nameplate data; and
f) conformance conditions.
This Standard is intended for the guidance of manufacturers, engineers, installers, contractors, and users.
This Standard is subject to review and amendment as technology advances.
Scope
1.1
This Standard applies to factory-manufactured residential, commercial, and industrial packaged terminal air-conditioners and heat pumps as defined in Clause 3.
1.2
This Standard applies to electrically operated vapour-compression refrigeration systems.
1.3
Packaged terminal air-conditioners and heat pumps are intended for unducted installation, but may be employed with ductwork having external static resistance up to 25 Pa (0.1 in H2O).
1.4
This Standard does not apply to the following:
a) heat-operated air-conditioning/heat pump equipment or room air-conditioners/heat pumps, as defined in CAN/CSA-C368.1;
b) water-to-air and brine-to-air heat pumps, as defined in CAN/CSA-C13256-1 and ISO 13256-1;
c) unitary air-conditioners and air-source unitary heat pumps, as defined in CAN/CSA-C656 and ANSI/AHRI 210/240, with capacities less than 19 000 W (65 000 Btu/h);
d) commercial and industrial unitary air-conditioners and heat pumps, as defined in CAN/CSA-C746 and ANSI/AHRI 340/360, with capacities of 19 000 W (65 000 Btu/h) or greater;
e) commercial and industrial single package vertical air-conditioners and heat pumps, as defined in ANSI/AHRI 390, with capacities of 39 300 W (134 000 Btu/h) or less; and f) units with integral gas-fired heating.
1.5
In this Standard, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
1.6
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
