Preface 

This is the first edition of CSA P.15, Test method for rating micro combined heat and power (mCHP) devices. CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Canadian Gas Association, Enbridge, SaskEnergy, and Energir. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. The following content are adapted from ©ASHRAE, www.ashrae.org. (2020) ASHRAE 204: Clauses 4.2 (partially), 5.3, 6, and 7.2 and Table 2. This Standard was prepared by the Subcommittee on Micro Combined Heat and Power (mCHP), under the jurisdiction of the Technical Committee on Energy Efficiency and Related Performance of Fuel- Burning Appliances and Equipment and the Strategic Steering Committee on Fuels and Appliances, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. 

Scope 

1.1 Applications 

This Standard applies to devices meeting the following conditions: a) stationary packaged systems designed for single family residential and small commercial applications; b) mCHP fuel gas devices, including different prime mover/generator types (e.g., steam, organic Rankine cycle, fuel cell, and IC); c) mCHP with net AC electrical output less than 10 kW; and d) mCHP with useful thermal output less than 85 kW. 

1.2 Test details 

This Standard covers a) performance testing at cold outdoor temperature; b) testing part load efficiencies (including below 50% electrical output); c) testing the performance, indoor versus outdoor unit installation; and d) flue gas waste heat recovery. 

1.3 Terminology 

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. 

1.4 Units of measure 

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.
