Tu, K M; Fischler, S

Two heat-recovery units were retrofitted, one at a time, with one heat pump and one storage-type water heater to produce two integrated heat pump - heat recovery unit - water heater systems. Each system was operated with appropriate measuring devices to determine the effect(s) of using the retrofit heat recovery unit on the performance of the heat pump and water heater. The system was operated with the outdoor unit of the heat pump in an environmental chamber with outdoor temperatures of 75, 85, 95, and 20F. The indoor unit of the heat pump was in an environmental chamber whose indoor temperature was set at 80F when the outdoor temperature was 75, 85, 95F, and 70F when the outdoor temperature was set at 20F. The indoor relative humidity was maintained at approximately 50%. The heat recovery unit and water heater were in an environmental chamber set at the basement temperature of 65F with 50% relative humidity.
