Flash Defrost Can Reduce Supermarket Cooling Energy Costs by Up to 20 Percent
January 5, 2015
Frigesco has been awarded new UK Department of Energy & Climate Change (DECC) funding of £102,000 to develop a flash defrost system for use in air-source heat pumps (ASHPs). Flash defrost can reduce supermarket cooling energy costs by up to 20 percent. Field trials in working supermarkets are currently underway.
A report by the European Heat Pump Association (EHPA) has found that after three years of stagnation the European heat pump markets are recovering. It indicates that 771,245 heat pump units were sold in Europe in 2013, an increase of 3 percent, and early data for 2014 show this trend to continue.
Manufacturers had a lot to like about last year. According to the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), shipments of equipment increased in just about every category in 2013. Especially notable were shipments of air-source heat pumps, which were up 16 percent over 2012.
Sales of air-source heat pumps used to be concentrated primarily in the Southern U.S., but that is changing as consumers become more aware of their energy-saving capabilities. In fact, in many markets, it may be more cost-effective to use an air-source heat pump for the majority of a homeowner’s heating and cooling needs.
The energy-efficiency ratings of residential air-source heat pumps have risen dramatically over the last few years, with many manufacturers now offering equipment well exceeding the 20-SEER mark. There have been significant gains made in commercial heat pump efficiencies as well.
Comfort and Higher Efficiencies are Hallmarks of Commercial Products

It’s time again for the Commercial Cooling Showcase. The NEWS’ annual issue has traditionally introduced the latest air conditioning units available for the upcoming summer season. The intent is to help contractors prepare for this busy period by doing the research that will help them distinguish between brands.
Pair to Develop, Manufacture Geothermal and Water-Source Heat Pumps
November 25, 2013
Carrier Corp. and Robert Bosch North America Corp., signed an agreement to form a joint venture to develop and manufacture geothermal and water-source heat pumps for the North American residential and commercial segments, the companies announced recently.
The season was getting colder and heating calls were beginning to come in. Bob and Tim were riding to a large residence that had three heat pumps to provide heating and cooling for the structure and Tim asked a question, “Why are heat pumps so popular?”
