EN 15316-4-2:2017

This European Standard covers heat pumps for space heating, heat pump water heaters (HPWH) and heat pumps with combined space heating and domestic hot water production in alternate or simultaneous operation, where the same heat pump delivers the heat to cover the space heating and domestic hot water heat requirement.The standard provides a calculation method under steady conditions that corresponds to one calculation step.The results of this calculation are incorporated in larger building models and take in account the influence of the external conditions and building control that influence the energy requirements for heating supplied by the heat pump system.The scope of this part is to standardize the:-required inputs;-calculation methods;-required outputsGeneration for space heating and domestic hot water production of the following heat pump systems, including control of:-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.This standard does not cover sizing or inspection of heat pumps.This standard deals with heat generators for heating or for combined domestic hot water and heating service. Generators for domestic hot water only are taken into account into module M8-8.NOTE 1Heat pumps for cooling systems are taken into account into module M4–8.NOTE 2Heat pumps for space heating using air (distribution) are taken into account in module M5–8.Other generation systems such as boilers are covered in other sub modules of part M3-8.This is the revision of EN 15316 4 2:2008. The revision covers the adaptation of the standard to hourly and monthly energy calculation.Table 2 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in prEN ISO 52000 1.NOTE 1In prCEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation.NOTE 2The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively.
