China: new CO2 heat pump standard

Standard GB/T26181-2010 is for hermetic motor-compressors for household and similar-use heat pump water heaters using CO2 refrigerant, and is expected to accelerate the introduction of new products on the Chinese market.
On June 1, 2011 a new Chinese CO2 heat pump standard was formally implemented. Standard GB/T26181-2010 is for hermetic motor-compressors for household and similar-use heat pump water heaters using CO2 refrigerant, and is expected to accelerate the introduction of new products on the Chinese market.

The CO2 heat pump standard delineates requirements for compressor cooling capacity, the coefficient of performance (COP), and noise levels. It is based on the characteristics and features of products in the Chinese market. More stringent standards are expected to follow in the future.
