The Air-Conditioning, Heating and Refrigeration Technology Institute (AHRTI) recently completed an 18- month research project titled ‘Life cycle climate performance (LCCP) model for residential heat pump systems.’ A Microsoft Excel-based tool has been developed to calculate LCCP for residential heat pumps.
The LCCP model includes the direct impact of refrigerant emissions, the indirect impact of energy consumption used to operate the heat pump system and the energy to manufacture and safely dispose the system and refrigerant. With appropriate input, the tool can handle different heat pump systems, refrigerants, locations and CO2 emission profiles. The final report and calculation tool are available online: http://www.ahrinet.org.
