Scope

GB/T 9237-2017 is the English-translated version of 制冷系统及热泵安全与环境要求.

GB/T 9237-2017 is the Chinese standard "[Including 2019XG1, 2020XG2] Refrigerating systems and heat pumps -- Safety and environmental requirements".

Its scope clause reads: This standard specifies the personal and property safety requirements and environmental protection requirements related to refrigeration systems and heat pumps, and establishes refrigeration systems.

Procedures for operation, maintenance, overhaul, and refrigerant recovery. This standard specifies the classification and selection principles of refrigeration systems and heat pumps and the limits of refrigerant charge.

This standard also specifies the requirements for the design, construction, and installation of refrigeration systems (including piping, components, materials, and auxiliary equipment that are directly connected to them).

Preparation), as well as requirements related to testing, commissioning, marking and documentation. Secondary heat transfer in addition to safety devices associated with refrigeration systems The requirements for the loop are not included in this standard.

This standard also specifies the safety requirements associated with the installation site, which may be due to the needs of the refrigeration system and its accessories.

Yes, but not necessarily directly related. The safety and environmental requirements specified in this standard also relate to the operation, maintenance and overhaul of refrigeration systems, as well as various refrigerants and systems.

Recycling, reuse and disposal of refrigerant oils, heat transfer fluids, refrigeration systems and their components.

This standard applies to. a) fixed or mobile refrigeration systems of all sizes, including heat pumps; b) secondary cooling or heating system; c) the installation location of the refrigeration system; d) parts or added parts that have been replaced after adopting this standard, if their functions and capabilities have changed before and after; e) New refrigeration systems, retrofits of legacy systems, variant systems, systems for replacing refrigerants, and old systems that change locations.

This standard does not apply to automotive air conditioning systems, nor to goods stored to prevent deterioration and contamination. 19.1.1.1, 19.1.1.2, 19.1.3, 19.2.1.1~19.2.1.4, 19.2.2, 19.2.3.1, 19.2.3.3 and 19.3.6 of this standard do not apply.

A unitized system that is packaged at the factory and equipped with a power cord and complies with the GB 4706 series of standards.
