Conditioning and heat pump units operating in Atlanta, Georgia, USA. LCCP values are calculated for three efficiency levels − seasonal energy efficiency ratio (SEER) levels of 10, 12, and 14 Btu Wh-1. By 2010 when HCFC-22 has been phased out for new … Access Document
YouTube – Chlorodifluoromethane – YouTube
This colorless gas is better known as HCFC-22, or R-22. It was once commonly used as a propellant and in air conditioning applications. A heat pump is a machine or device that moves heat from one location (the 'source') at a lower temperature to another location (the 'sink' or 'heat … View Video
PROJECT PROPOSALS: CHINA
The type of refrigeration systems under this project, here called “commercial air-source chillers/heat pump” are systems UNDP pointed to the good performance of HFC-32 in particular for heat pumps, the moderate GWP in comparison to HCFC-22, and the lack of other alternatives. … Document Retrieval
Refrigerant – Wikipedia, The Free Encyclopedia
A refrigerant is a substance used in a heat cycle usually including, for enhanced efficiency, a reversible phase change from a liquid to a gas. Traditionally, fluorocarbons, especially chlorofluorocarbons, were used as refrigerants, but they are being phased out because of their ozone depletion … Read Article
