Up until recently, sales of air-source heat pumps were on a tear, growing from 1.6 million units in 2009 to 2.3 million units in 2014, according to the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). But, in 2015, sales of heat pumps slipped 3.6 percent from the previous year.
Just about every manufacturer recommends homeowners have their air-source heat pumps serviced twice a year — once in the spring and once in the fall. Most believe that semi-annual maintenance helps keep equipment operating at peak performance and ensures the unit is ready for the heat of summer or cold of winter.
Not that long ago, if a conversation centered on heat pumps, it was fairly safe to assume that the equipment referred to ducted, split-system, electric, air-source units. That assumption started to change a few years ago with the growing popularity of ductless heat pumps.
Also enhances air-source heat pump efficiency and comfort in milder climates
May 20, 2016
The U.S. Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL), collaborating with Emerson Climate Technologies, developed a prototype for an air-source heat pump for the colder regions of the country — one that heats better and uses significantly less energy.
The HRC Series’ two-piece chassis is housed in an attractive cabinet with a durable powder-coat finish. A 5-inch sub-base and a louvered grille are available as options. Unit controls include advanced digital changeover between heating and cooling along with fan speed selection.
Xergy Inc. has announced a new refrigeration system based on an electrochemical compressor to replace the conventional mechanical vapor compression systems found in typical heat pumps. The company credits the University of Delaware’s Ajay Prasad and his research team with playing an important role in the breakthrough.
Every year, The NEWS introduces the latest cooling equipment available for the upcoming summer season in order to help contractors prepare for this busy period by doing the research that will help them to distinguish between brands. The coverage features specific information about each individual product as submitted by the manufacturers.
Now approved for certification testing for packaged unitary small HVAC products
