Abstract
The following appendices to a final report on evaluating the potential for improving the performance, reliability, cost and energy demand of heat pumps for use in northern climates are included in this volume: details of optimization analysis; sensitivity analyses; potential component modifications; modified compressor analysis; frost penalty modeling; alternative refrigerant study; performance characteristics of the quasi-optimum heat pump systems; initial system configurations; selection of system configurations; TRNSYS program modifications and additions; weather data input preparation for TRNSYS simulation; development of input data for TRNSYS program; solar collector sizing study; component sizing and sizing sensitivity study; control logic; system seasonal simulation results; effect of compressor and defrost on-off cycles on system annual cost; sensitivity of the recommended systems to variations in reliability or maintenance costs; sensitivity of the studied systems annual cost to energy cost excursions; effect of discount rate on HVAC system annual cost; economic analysis computer code; and residential incremental building costs due to changes in level.
