The 2013 update on the Canadian CFC chiller stock study from the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) estimates that 83 chillers previously operating on CFC refrigerants were converted or replaced during the year 2013 in Canada. This is a decrease from the number of conversions/replacements completed in 2012 (148). The conversion and replacement numbers for 2012 bring the total number of converted or replaced chillers from 3788 (2012) to 3871 and the rate of conversion/replacements from 86.4 per cent (2012) to 88.3 per cent. These numbers are based on the new baseline number determined in 2011, which updated the HRAI’s study Determining a Baseline Number of CFC Chillers in Canada, published in July of 2000.
HRAI notes that 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.
