Preface

This is the second edition of CSA C273.5, Installation of air source heat pumps and air conditioners. It supersedes the previous edition published in 1980. It covers installation of unitary, factory-assembled air conditioners and heat pumps (air sink and air source) up to 19 kW (65,000 Btu/h). It should be noted that this edition now includes requirements for air conditioners as well.

CSA acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada (NRCan), Ontario Ministry of Energy, and Fortis BC.

This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.

This Standard was prepared by the Subcommittee on Installation of Residential Air Source Heat Pumps and Air Conditioners under the jurisdiction of the Technical Committee on Heating, Ventilation, Air Conditioning, and Refrigeration and the Strategic Steering Committee on Performance, Energy Efficiency, and Renewables, and has been formally approved by the Technical Committee.

February 2011

Notes: (1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.(2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains

the responsibility of the users of the Standard to judge its suitability for their particular purpose.(3) This publication was developed by consensus, which is defined by CSA Policy governing standardization — Code of

good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this publication.

(4) To submit a request for interpretation of CSA Standards, please send the following information to [email protected] and include “Request for interpretation” in the subject line:(a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch;(b) provide an explanation of circumstances surrounding the actual field condition; and(c) where possible, phrase the request in such a way that a specific “yes” or “no” answer will address the issue.Committee interpretations are processed in accordance with the CSA Directives and guidelines governing

standardization and are published in CSA’s periodical Info Update, which is available on the CSA website at http://standardsactivities.csa.ca.

(5) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee. To submit a proposal for change to CSA Standards, please send the following information to [email protected] and include “Proposal for change” in the subject line:(a) Standard designation (number);(b) relevant clause, table, and/or figure number;(c) wording of the proposed change; and(d) rationale for the change.

C273.5-11Installation of air source heat pumps and air conditioners

1 Scope

1.1This Standard covers the installation requirements for unitary air conditioners and air source heat pumps for residential applications with cooling ratings up to 19 kW (65 000 Btu/h).

1.2This Standard covers installations in new construction and, where applicable, in installations that are part of an existing system.

1.3This Standard covers equipment requirements, system design, equipment selection, minimum installation requirements, and information to be provided to the owner.

1.4In CSA standards, “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.

1.5The values given in SI (metric) units are the standard. The values given in parentheses are for information only.

2 Reference publicationsThis Standard refers to the following publications and where such reference is made, it shall be to the edition listed below, including all amendments published thereto.

C22.1-09Canadian Electrical Code, Part I

CAN/CSA-F280-M90 (R2009)Determining the required capacity of residential space heating and cooling appliances

HRAI (The Heating, Refrigeration and Air Conditioning Institute of Canada)SAR-R1 (1996)Residential Heat Loss/Heat Gain Calculations Manual

3 DefinitionsThe following definitions apply in this Standard.

AHRI certified reference number — a unique number assigned by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) to a combination of outdoor and indoor unit model numbers and the certified performance of that combination at standard rating conditions.

Balance point — the outdoor temperature below which the heat pump cannot supply the total heating requirements of the structure.

Central-ducted air conditioner or heat pump — a device for circulating, filtering, cooling, and/or heating air of a whole house via a central ducting system that consists of one or more factory-made assemblies that normally include an indoor conditioning coil, evaporator or cooling coil, a compressor, and an outdoor coil or condenser with controls for automatic cooling or heating, or both.

Cut-off — an adjustable thermostatic device (typical on dual fuel applications) that senses outdoor temperature and can be set to turn off the heat pump.

Ductless air conditioner or heat pump — a device for circulating, filtering, cooling, and/or heating air of a specific area or areas of a house by providing air directly into the area or areas without the use of a ducting system and that consists of one or more factory-made assemblies that normally include an indoor conditioning coil, evaporator or cooling coil, a compressor, and an outdoor coil or condenser with controls for automatic cooling or heating, or both.

Economic cut-off — the cut-off setting that corresponds to the outdoor temperature below which it is more economical to use the back-up heat.

Electronically commutated motor (ECM) — a low wattage AC or DC motor that is more efficient over a range of speeds than a standard blower motor.

Heat recovery ventilator (HRV) — a unitary, factory-assembled heat-exchange unit installed between incoming fresh air and exhaust air.

Mini-ducted air conditioner or heat pump — a device for circulating, filtering, cooling, and/or heating air of a specific area or areas of a house via a dedicated, non-central ducting system that consists of one or more factory-made assemblies that normally include an indoor conditioning coil, evaporator or cooling coil, a compressor, and an outdoor coil or condenser with controls for automatic cooling or heating, or both.

February 2011 3

Multi-stage constant capacity system — an air conditioner or heat pump system that uses two or more constant speed compressors of which the capacity is controlled by switching the compressors on and off in stages to achieve partial capacity and power input during partial load conditions.

Owner — the person or persons having ownership or control of the air conditioner or heat pump at the start-up date.

Qualified — acceptable to the authority having jurisdiction.

Single-stage constant capacity system — an air conditioner or heat pump system that uses one constant speed compressor, of which the capacity is controlled by switching the compressor on and off to achieve either 100% capacity or 0% capacity.

Variable refrigerant flow system — an air conditioner or heat pump system that uses one or more variable speed compressors, of which the capacity and power input is controlled over a wide range by electronically adjusting the rotation speed of the compressors and thus the refrigerant mass flow rate in order to constantly and closely match changing space heat loads.

Unitary air conditioner or heat pump — a device for circulating, filtering, cooling, and/or heating air that consists of one or more factory-made assemblies that normally include an indoor conditioning coil, evaporator or cooling coil, a compressor, and an outdoor coil or condenser with controls for automatic cooling or heating, or both.

4 Equipment requirements

4.1Air conditioners and heat pumps shall comply with CAN/CSA-C656.

5 System design

5.1The installer should be aware of the requirements of the authority having jurisdiction.

5.2The system (if new) shall require heat loss and heat gain calculations in accordance with CAN/CSA-F280, (e.g., HRAI SAR-R1).

For air system design, guidelines or other acceptable methods shall be used (e.g., HRAI SAR-R1).

5.3Note: See Table 1.

5.3.1 Single-stage constant capacity — Central ductedA single-stage central air conditioner and heat pump shall be selected with a cooling capacity between 0.95 to 1.15 of the total heat gain of the house as calculated in accordance with CAN/CSA-F280 (e.g., HRAI SAR-R1). A heat pump may be sized at 1.25 of total heat gain at the discretion of the designer; in this case, the next smaller nominal sized unit that is available shall be selected.

5.3.2 Multi-stage containing two or more constant capacity compressors — Central ductedA multi-stage central-ducted air conditioner and heat pump system shall be sized to meet or partially meet the design heat loss of the house as calculated in accordance with CAN/CSA-F280 (e.g., the HRAI residential heat loss calculations as set forth in HRAI SAR-R1).

However, the lowest capacity that can be provided by the system in the first stage cooling mode operation shall not exceed 125% of the design heat gain of the zones it serves as calculated in accordance with CAN/CSA-F280 (e.g., the HRAI residential heat loss calculations as set forth in HRAI SAR-R1).

5.3.3 Variable refrigeration flow — Central ductedA variable refrigerant-flow central-ducted air conditioner and heat pump shall be sized to meet or partially meet the design heat loss of the house as calculated in accordance with CAN/CSA-F280 (e.g., the HRAI residential heat loss calculations as set forth in HRAI SAR-R1).

However, the lowest “turned down” capacity that such a system can provide in cooling mode shall not exceed 125% of the design heat gain as calculated in accordance with CAN/CSA-F280 (e.g., the HRAI residential heat gain calculations as set forth in HRAI SAR-R1).

5.3.4 Single-stage constant capacity — Ductless and mini-ductedSingle-stage ductless and mini-ducted air conditioners and heat pumps shall be selected with a cooling capacity between 0.95 and 1.15 of the total heat gain of the areas served as calculated in accordance with CAN/CSA-F280 (e.g., HRAI SAR-R1). A heat pump may be sized at 1.25 of total heat gain of the zones served at the discretion of the designer; in either case, the next larger nominal sized unit that is available shall be selected.

5.3.5 Multi-stage constant capacity — Ductless and mini-ducted containing two or more constant speed compressorsMulti-stage constant capacity ductless and mini-ducted systems shall be sized to meet or partially meet the design heat loss of the areas it serves as calculated in accordance with CAN/CSA-F280 (e.g., HRAI SAR-R1).

However, the lowest capacity that can be provided by the system in the first stage cooling mode operation shall not exceed 125% of the design heat gain as calculated in accordance with CAN/CSA-F280 (e.g., the HRAI residential heat gain calculations as set forth in HRAI SAR-R1) for the same areas.
