CSA SPE-07:23

Preface

This is the first edition of CSA SPE-07, Load-based and climate-specific testing and rating procedures for heat pumps and air conditioners . It supersedes the document CSA EXP07 of the same name. This Document is not a consensus product; that is, it is not a Standard and it has not been formally reviewed or approved by a CSA Technical Committee. This Document presents an alternative approach to testing the performance of heat pumps and air conditioners. In the past, most performance test procedures have required the monitoring of equipment while operating under steady state conditions, at a fixed capacity, while subjected to specific and fixed indoor and outdoor air conditions. This Document uses a load-based test approach in which the indoor room is subjected to a simulated load and the equipment is allowed to respond accordingly as it tries to maintain the desired indoor conditions while outdoor room conditions are held constant. This allows the actual behaviour of the equipment and controls to be measured in the test facility in a manner much more representative of in situ performance. For those portions of the test procedure where the simulated load might exceed the equipment capacity, more conventional full-load testing is used. This Document has been prepared and reviewed by the SPE-07 Development Committee. CSA acknowledges that the development of this Standard was made possible, in part, by the financial support of BC Hydro, Efficiency Manitoba, Efficiency Nova Scotia, FortisBC Inc., Hydro-Québec, Independent Electricity System Operator (IESO), Natural Resources Canada, Nova Scotia Department of Natural Resources and Renewables, and Northwest Energy Efficiency Alliance (NEEA).

Scope

1.1 General

1.1.1 This Document applies to unitary air conditioners and heat pumps that are a) factory-made; b) air-source and air-sink; c) single-split systems with matching assemblies or single package for use in ducted and/or non-ducted distribution systems; d) intended for space-heating and/or air-conditioning applications in buildings; e) electrically driven, mechanical, vapour-compression-type systems; and f) rated below 65 000 Btu/h (19.0 kW) heating or cooling at standard rating conditions, in accordance with Clause 5.2.

1.1.2 This Document does not apply to the following: a) water-to-air and/or water units; and b) heat recovery.

1.2 Unitary equipment Unitary equipment within the scope of this Document is outlined in Table 1.

1.3 Terminology In this Document, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with this Document; “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 this Document. 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.

1.4 Units of measurement The values given in IP (inch-pound) units are the units of record for the purposes of this Document. The values given in parentheses are for information and comparison only.
