In 2011, several developing countries, termed "Article 5" countries under the Montreal Protocol, made key investments in natural refrigerants. China saw several developments regarding R744 refrigeration and heat pumps, whilst in Brazil the first CO2 only supermarket was showcased. An innovative project in Pakistan will see the development of a hybrid solar water heater using CO2. looks at the most popular news items about "Article 5" countries in this “best of 2011”, summarising the key developments below.
Tesco opens its first CO2 refrigeration store in China, 17 August 2011Early August 2011, retailer Tesco opened its 97th store in China, yet the first one to feature a CO2 refrigeration system reducing the amount of HFC refrigerant charge from 1,500kg to 120kg. The Shanghai store uses 25% less energy than standard store designs and is expected to reduce annual electricity consumption and carbon emissions by 1.18 million kwh and 1,176 tons respectively.
Exclusive interview with Professor J. Chen about CO2 heat pumps in China , 4 August 2011Dr. Jiangping Chen, Professor of the Institute of Refrigeration and Cryogenics at Shanghai Jiao Tong University, talked to about the imminent launch of CO2 heat pump water heaters in China, the special conditions in the Chinese market, the main barriers to overcome and the prospect of success of the technology in the country.
New Chinese CO2 heat pump standard, 14 July 2011On 1 June 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 to the Chinese market.
Innovative Pakistan solar water heating project with CO2 as working fluid, 5 July 2011A project to provide an alternate energy system in Gilgit-Baltistan, Pakistan, will see the development of an ecologically friendly hybrid solar water heating system that uses CO2 as the working fluid. The project is a joint collaboration between the Pakistan-US Science and Technology Programme (USAID) and the Higher Education Commission (HEC) of Pakistan.
