Air to water heat pumps — Testing and rating for performance — Part 2: Space heating and/or space cooling
This document specifies test conditions and test procedures for determining the performance characteristics of air to water heat pumps for space heating and/or space cooling with electrically driven compressors with or without supplementary heater. The purpose of this document is to rate the performance of the air to water heat pumps for space heating and/or space cooling. In the case of air to water heat pumps for space heating and/or space cooling consisting of several parts with refrigerant or water connections, this document applies only to those designed and supplied as a complete package. This document does not apply to large chiller or large liquid chilling package for space cooling and/or heating. This document does not apply to air to water heat pumps not intended for human comfort. NOTE Testing procedures for simultaneous operation for hot water supply and space heating and/or space cooling are not treated in this document. Simultaneous means that hot water supply and space heating and/or space cooling generation occur at the same time and can interact.
