The document specifies test conditions for determining the seasonal performance characteristics of air source heat pump water heaters for space heating with electrically driven compressors with or without supplementary heater. The purpose of this document is to rate performance of the heat pump water heaters for space heating with no operation of any supplementary heater. In the case of heat pump water heaters for space heating consisting of several parts with refrigerant or water connections, this document applies only to those designed and supplied as a complete package.<\/p>\n
The seasonal coefficient of performance depends, inter alia, on the climate conditions and temperature regime of the space heating distribution network.<\/p>\n
This document defines:<\/p>\n
three design conditions, each of them being characterized by a design temperature which represents the lowest temperature that can occur in that design condition;<\/p>\n<\/li>\n
three water temperature distribution regimes, namely \u201c temperature application\u201d in the text.<\/p>\n<\/li>\n<\/ul>\n
The user of this document is free to determine the seasonal coefficient of performance for one or more of the defined design conditions and for one or more of the defined temperature applications.<\/p>\n
This document also provides a full description of three heating seasons that can be used with the associated design conditions.<\/p>\n
