UNE-EN 15316-4-2:2019

The 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 standardise the:¾ðrequired inputs;¾ðcalculation methods;¾ðrequired outputsfor output thermal power generation for space heating and domestic hot water production of the following heat pump systems, including control:¾ðelectrically-driven vapour compression cycle (VCC) heat pumps;¾ðcombustion engine-driven vapour compression cycle heat pumps;¾ðthermally-driven vapour absorption cycle (VAC) heat pumps,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 generators for cooling systems are taken into account into module M4-8.NOTE 2Heat pumps generators 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.
