scope:

This International Standard is applicable to heat pumps for space heating and cooling, heat pump water heaters (HPWH), and heat pumps with combined space heating and/or cooling and domestic hot water production, in alternate or simultaneous operation, where the same heat pump is used for space heating and domestic hot water heating. This part specifies the ? required inputs; ? calculation methods, and ? required outputs for output thermal power generation for space heating and cooling and domestic hot water production of the following heat pump systems, including control: ? electrically-driven vapour compression cycle (VCC) heat pumps; ? combustion engine-driven vapour compression cycle heat pumps; ? thermally-driven vapour absorption cycle (VAC) heat pumps, using combinations of heat source and heat distribution listed in Table 1.
