Packaged Water Chillers – New Regulations
Bulletin – October 2004
The 8th amendment to Canada's Energy Efficiency Regulations (the Regulations) was approved on September 1, 2004. For the first time, chillers are part of the federal regulations and are required to comply with minimum energy efficiency performance levels. The requirements pertain to chillers that are imported or shipped interprovincially for sale or lease in Canada.
The amendment has been published on page 1275 of the Canada Gazette Part II
Product Description
Packaged water chillers are used to cool large buildings. The new requirements apply to factory-designed and prefabricated vapour-compression chillers that have a cooling capacity of less than 7000 kW (2000 tons) with water condensers and less than 700 kW (200 tons) designed for use with air condensers. Absorption chillers of up to 5600 kW (1600 tons) are also included in the Regulations.
Energy Performance Test Procedure
The classification of equipment and testing procedure are described in CSA-C743-02, entitled "Performance Standard for Rating Packaged Water Chillers." This standard is available in French and English from:

Energy Efficiency Performance
Packaged water chillers manufactured on or after the effective date must meet the minimum coefficient of performance (COP) and integrated part-load value (IPLV) as specified in CSA-C743-02, Section 6, and listed in Table 9, as shown below, or minimum adjusted COP and non-standard part load value (NPLV) for centrifugal equipment not designed to operate at standard rating conditions in Tables 10 to 15 of CSA-C743-02.

Reporting Requirements
The energy efficiency report (Section 5 of Canada's Energy Efficiency Act) requires reporting of the following information:
- product name
- manufacturer name
- energy efficiency certification organization
- brand or model name
- model number
- equipment type (corresponds to the descriptions in the tables in CSA-C743-02, "Performance Standard for Rating Packaged Water Chillers")
- net cooling / heating capacity in kW or tons
- COP
- IPLV
- NPLV and list of non-standard conditions as per CSA-743-02, if designed for non-standard conditions.
This report must be submitted by the dealer to the Minister of NRCan before the product is imported into Canada or traded interprovincially for the first time.
Verification Requirements
The same verification requirements that apply to other products regulated under the Energy Efficiency Regulations apply to packaged water chillers.
Regulated packaged water chillers must carry a verification mark indicating that the energy performance of the product has been verified. The verification mark is the mark of a Standards Council of Canada accredited certification organization that administers an energy performance verification program for this product. This organization must be recognized by NRCan. NRCan will accept labels issued by a province indicating that the product meets the provincial energy efficiency levels as a verification mark, providing that the provincial level is equivalent to or exceeds the federally regulated level.
Effective Dates
These energy efficiency standards for packaged water chillers came into effect on October 28, 2004.
