Scope

Scope: This standard specifies the terms and definitions, classification, models, requirements, test methods, inspection rules, marking, instructions, packaging, transportation, and storage of multi-energy integrated gas heating and hot water systems (hereinafter referred to as "the system"). This standard applies to: a) Multi-energy integrated gas heating and hot water systems composed of a gas-fired heat source unit and one or more additional energy sources, which have both heating and domestic hot water heating functions. The nominal capacity of the storage water tank for the domestic hot water heating system shall not exceed 600 L, and the capacity range of the heat source unit shall be: the power of the gas-fired heating unit shall not exceed 70 kW, the rated heating power of the air-source heat pump shall not exceed 70 kW, the area of the solar collector shall not exceed 32 m2, and the temperature of the heating water shall not exceed 95 °C, while the temperature of the domestic hot water shall not exceed 65 °C; b) Multi-energy integrated heating systems composed of a gas-fired heat source unit and one or more additional energy sources, which only have heating functions. This type of system is a simplified version of the systems with both heating and domestic hot water heating functions; c) Multi-energy integrated heating systems composed of a gas-fired heat source unit and one or more additional energy sources, which have independent domestic hot water heating functions. The nominal capacity of the storage water tank for the domestic hot water heating system shall not exceed 600 L, and the capacity range of the heat source unit shall be: the power of the gas-fired heating unit shall not exceed 70 kW, the rated heating power of the air-source heat pump shall not exceed 10 kW, and the area of the solar collector shall not exceed 32 m2, and the temperature of the domestic hot water shall not exceed 65 °C. This standard does not apply to: a) Systems t
