T/GDC 74-2020 Heating and hot water integrated heat pump unit
Basic Information
Scope
Scope: This standard specifies the terms and definitions, types and basic parameters, requirements, test methods, inspection rules, energy efficiency labels, and market supervision and inspection for integrated heating and hot water heat pump units. This standard applies to air-source heat pump water heaters that use electric motor-driven, vapor-compression refrigeration cycles and air as a heat source for providing household heating and hot water. Other similar air-source heat pump water heaters can also be used as reference. This standard provides definitions and test conditions for SCOP, SCOPon, and SCOPnet; Main technical content: Space heating partial load conditions, test condition design, seasonal space heating efficiency requirements, seasonal space heating energy efficiency grades, and noise levels.
