In order to standardize industry standards, in 2008 and 2009, the state successively introduced and implemented GB/T21362-2008 "Commercial or Industrial and Similar Heat Pump Water Heaters" national standard for commercial machines, and GB/T "Household and similar heat pump water heaters" National standard for household machines.
The standard unifies the test conditions and methods of domestic air energy water heaters and commercial water heater systems, and stipulates that under the specified standard environmental conditions, the energy efficiency ratio cop is not lower than 3.4, and the cycle heating energy efficiency ratio cop is not lower than 3.7.
In particular, on September 26, 2010, the General Administration of Quality Supervision, Inspection and Quarantine and the National Bureau of Standardization Management jointly issued the GB25127.2-2010 "Low Ambient Air Source Heat Pump (Cold Water) Unit", which is in the National Cold Standard Committee. Under the strong promotion, it was also implemented on February 1, 2011, which puts strict quality standards on the low ambient temperature operation that has long plagued the air energy industry.
