Peak Demand Reduction with Dual-Source Heat Pumps Using Municipal Water
MetadataShow full item record
The objective of this project was to examine a dual-source (air and/or water-coupled) heat pump concept which would reduce or eliminate the need for supplemental electrical resistance heating (strip heaters). The project examined two system options: switching on demand between completely air-source and completely water-coupled or using a concurrent partial water-coupled and partial air-coupled mode operation. The water supply for the water-coupled mode of operation would be the municipal water system. An estimate of the economic worth of this system concept was made by examining the incremental cost to install such a system against the expected savings associated with these systems.
