Danfoss, Bethpage, N.Y., conducted an online survey to gauge industry acceptance of CO2 refrigeration systems in North America.
Intended to serve as an industry indicator, the survey collected input from commercial and industrial refrigeration OEMs, consultants, contractors and end users.
According to the survey, the commercial refrigeration industry continues to see CO2 as a viable mainstream technology for refrigeration (82% of OEMs; 91% of consultants and end users), and about half of OEMs responding see CO2 refrigeration as being at least 16% of their business within the next five years. In a similar study conducted in 2012, less than 20% of OEMs saw CO2 comprising at least 16% of their business.
The majority of today’s commercial refrigeration consultants and end users are engaged in CO2 projects, citing pending legislation/regulations and corporate sustainability goals as key drivers in the decision to use CO2. However, they also identified the high initial system cost as a primary barrier to deployment.
“The results of this survey validate the ongoing growth we are seeing in CO2 projects across North America,” says Peter Dee, sales and services director – food retail. “Globally, Danfoss has been involved in more than 10,000 CO2 refrigeration projects, and we are using this experience to continue investing in technologies like our new CTM multi-ejectors that help to minimize the challenges and application barriers to CO2. We have also recently launched our CO2 mobile training unit to address the critical need for training.”
The survey also identified similar acceptance in the industrial refrigeration market. Fifty-seven percent of responding OEMs and contractors and 43% of consultants and end users indicated they have already been involved in a CO2 refrigeration project or have plans to be. However, OEMs and contractors do not see CO2 becoming a significant part of their business in the near future.
OEMs and contractors identified the removal of ammonia, in terms of improved safety and reduced ammonia charge, as key drivers in using CO2. Consultants and end users agreed, but also cited pending legislation/regulation as important factors. In contrast to the commercial refrigeration industry, industrial refrigeration respondents said the primary barrier to further CO2 use is the result of end user and contractor familiarity and training.
This industry indicator was conducted as a follow up to a similar survey conducted by Danfoss in 2012 to gauge the market acceptance of CO2 refrigeration. The survey was distributed via email to approximately 1,100 people that do business in commercial or industrial refrigeration applications.
