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?”
After strong January numbers, United States combined shipments of central air conditioners and air-source heat pumps have shown another upsurge, totaling 357,637 units in February 2013, up 20.8 percent from February 2012, according to the latest statistics from the Air-Conditioning, Heating, and Refrigeration Institute (AHRI).
CO2 as a refrigerant in cascade supermarket systems, transcritical applications, transport refrigeration, and heat pumps were among major developments in recent years. Here is a summary of those developments.
The refrigerator is actually a heat pump, as the method of operation is identical apart from one difference: Heat is extracted from the refrigerator and discharged into the surroundings, whereas the heat pump uses the thermal energy in the surroundings for heating purposes.
Two NuTone packaged systems — heat pumps and packaged gas/electric models — include all-aluminum microchannel coils for lighter weight, smaller size, better durability, and greater reliability in corrosive environments, said the company.
The expanding applications for ammonia in commercial refrigeration are being demonstrated in several recent projects involving heat pumps. What constitutes one possibility for efficient management of heat energy?
Designed to be an exact footprint replacement for a variety of manufacturers’ products, the THHP-Series space-constrained (formally known as through-the-wall) heat pumps are both AHRI certified and DOE compliant to meet the 12 SEER, R-410A requirements.
