Summary

This paper reports on ongoing work integrating a variable-capacity heat pump with additional heating and cooling technologies to provide efficiency and other benefits for residential customers. The Next-Generation Residential Space Conditioning System (Next-Gen RSCS) was tested in three leading U.S. laboratories as well as field evaluated at three homes in California. The Next-Gen RSCS integrates advanced HVAC technologies, including a variable-capacity compressor and variable-speed indoor blower, auto demand response, fault detection and diagnostics, intelligent dual-fuel heating, integrated heat recovery ventilation, and zonal control. An alternative refrigerant, R-32, was evaluated in laboratory testing as a possible future enhancement. An assessment was also performed on duct losses for single- versus multi-zone duct configurations with variable-capacity equipment. The field evaluation saw positive customer feedback, with users appreciating how quiet the units were, how quickly they cooled or heated the space, and their ability to control the temperature in individual spaces. The paper also begins a discussion to extrapolate project results beyond California climates, conditions, and demographics.
