Energy Consumption and Demand as Affected by Heat Pumps that Cool, Heat and Heat Domestic Water
MetadataShow full item record
Products or systems that heat, cool and heat domestic water, which are also referred to as integrated systems, have been available for several years. The concept is simple and appeals to consumers. This paper presents methods for evaluating the potential savings by using an integrated system that heats water by desuperheating discharge gas in the refrigeration cycle. The methods may be applied for any specific location, and their accuracy will depend on the accuracy of building loads and water usage estimates. Power demand can also be affected by electric water heaters. The methods presented demonstrate how integrated systems can be of value in reducing daily summertime peaks.
