[China Refrigeration Network] On April 4, 2019, the State Administration of Market Supervision and the National Standardization Administration jointly issued the No. 4 National Standards of the People's Republic of China in 2019, which approved the “light distribution performance of motor vehicles”. "21" national standards, including "low-environment temperature air source heat pump (cold water) unit energy efficiency limit value and energy efficiency rating" (GB 37480-2019) ranked 10th national standard. The announcement shows that the national mandatory standard will be implemented on May 1, 2020, and the focal point is the National Energy Foundation and Management Standardization Technical Committee, and the competent department is the National Standardization Management Committee.

　　National mandatory standard "Energy efficiency limit value and energy efficiency rating of low ambient temperature air source heat pump (cold water) unit" officially released

　　Under the background of the steadily advancing the "winter clean heating" in northern China, the release of "energy efficiency limit value and energy efficiency rating of low ambient temperature air source heat pump (cold water) unit" (GB 37480-2019) has great practical significance. For the bidding work of local government departments at all levels, the performance requirements, test methods and evaluation basis for evaluating such products are given. At the same time, it also provides the basis for the manufacturing and manufacturing of such products, which greatly ensures that the products are in Safety, reliability and applicability in actual use. It plays an active role in promoting the promotion and application of air source heat pump (cold water) unit products with low ambient temperature, and has positive significance for regulating the development of the industry.
