Abstract

A comprehensive analytical model using Excel and Visual Basic for Applications (VBA) has been developed to simulate life cycle climate performance (LCCP) for residential heat pumps. The LCCP model includes the direct impacts of refrigerant emissions, the indirect impacts of energy consumption used to operate the heat pump system, and the energy to manufacture and safely dispose the system and refrigerant. The annual energy consumption for heat pump operation, including backup heat, is calculated using input performance data at several operating points, in a number of different formats, assuming a linear relationship as defined in AHRI Standard 210/240. With appropriate input, the program can handle different heat pump systems, refrigerants, locations, and CO2 emission profiles of power plants.
