资源简介：
Water heating accounts for significant energy use in all of domestic, commercial and industrial applications. A prototype domestic water heating heat pump is described that uses a partial cascade between a R410A heat pump designed for air-conditioning and a R134a high stage. Cold water is heated to 62oC in one pass by matching it against the two cascade stages in series. Laboratory performance testing, combined with analysis based on typical metrological year climate data, suggests the system will achieve seasonal heating COPs > 3.1 at most New Zealand locations.
