Converted Canadian CFC Chiller Stock Remains Consistent

July 23, 2012
MISSISSAUGA, Ontario — The Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) recently released the 2011 update on the Canadian CFC chiller stock study. This update estimates that 252 chillers previously operating on CFC refrigerants were converted or replaced during the year 2011 in Canada. This represents approximately the same number of conversions/replacements that were completed in 2010 (253).

The conversion and replacement numbers for 2011 bring the total number of converted or replaced chillers from 3,388 (2010) to 3,640 and the rate of conversion/replacements from 72.2 percent (2010) to 83 percent. These numbers are based on the new baseline number determined in 2011 which updated the HRAI study, entitled “Determining a Baseline Number of CFC Chillers in Canada”, published in July of 2000.

The purpose of the program is to provide an ongoing estimate of the number of chillers in Canada that continue to operate on CFC refrigerants and track the annual rate of conversions and replacements of this chiller stock in future years.

Chiller, in this context, means refrigeration machinery having a centrifugal‐type compressor, an evaporator, a water‐cooled condenser, and having a capacity range of 100 through 1,200 tons. The most common application is to provide chilled water for air conditioning systems in buildings.
