PrefaceThis is the second edition of CSA C370, Cooling performance of portable air conditioners. It supersedes the previous edition, published in 2009.Scope1.1This Standard applies to the cooling performance of portable air conditioners that have a rated cooling capacity of 19 000 W (65 000 Btu/h) or less and provide cooled air in one of the operating configurations described in Table 1.Note: The air conditioners described in this Clause include air conditioners with heating capability.1.2This Standard does not apply to(a) testing and rating of individual assemblies, e.g., condensing units or direct expansion fan coil units for separate use;(b) computer or data processing room air conditioners within the scope of ANSI/ASHRAE 127;(c) room air conditioners within the scope of ANSI/AHAM RAC-1 or CAN/CSA-C368.1; and(d) the effects of air infiltration on portable air conditioners with single-duct condenser configurations.1.3In 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 (nonmandatory) to define their application.1.4The values given in SI (metric) units are the standard. The values given in parentheses are for information only.
