| Description/Abstract | The effects of thermostat setback on energy consumption by residential heat pumps were studied using a computer simulation based on laboratory and field data.^A fixed reduction in room thermostat setpoints was shown to be a very effective and essentially foolproof means for reducing energy consumption with a residential heat pump system.^For the severe northern climate (Minneapolis) chosen for the present study, approximately 8% savings in seasonal input energy (kWh) can be achieved with a typical system for each 1/sup 0/C setpoint reduction (4% per /sup 0/F).^It was found that nighttime setbacks of 5/sup 0/F or more can lead to increased energy consumption by the heat pump, high morning power demand, and poor indoor comfort; therefore, the general use of thermostat setback with residential air-source heat pump systems is not recommended.^(LCL) |
