Zhejiang business vocational college school-run enterprises, commercial machinery plant in zhejiang province and the national environmental protection signed R32 alternatives to R22 piston type refrigeration compressor project (multilateral fund as replacement project) agreement. This commercial machinery plant in zhejiang province to declare the multilateral fund as alternative project formally approved by the United Nations environment programme (unep) and the ministry of environmental protection, and received the United Nations Montreal multilateral fund $1.6 million. To accelerate the construction of ecological civilization construction, adhere to the basic state policy of resource conservation and environmental protection, in recent years, zhejiang vocational and technical college business increased support for school-run enterprise of zhejiang commercial machinery factory, focus on professional air conditioning at the provincial level engineering technology as the backing, the central financial support bases in the enthalpy potential method of air-conditioning equipment performance training room construction in zhejiang commercial machinery factory, and deepening the reform of work-integrated learning personnel training mode, improve the level of technical testing of the plant and environmental performance of products. In 2002, zhejiang commercial machinery factory won the United Nations environment programme and the state environmental protection administration approved (now the ministry), a UN \"ODS\" $1.71 million project funded by the world bank, \"ODS\" renovation project has been successfully (refrigeration compressor and upgrading transformation), and won unanimous favorable comment of the assessment team all the United Nations, world bank experts, known as China\'s \"ODS\" renovation project implementation model. At present, zhejiang commercial machinery factory has been become one of the nation\'s largest semi-hermetic refrigeration compressor manufacturers, product sales in the country are among the best in the industry. The R32 alternatives to R22 piston type refrigeration compressor after completion of project implementation, zhejiang commercial machinery factory will set up a suitable R32 environmental protection refrigerants of middle and small piston type refrigeration compressor production line and form batch production ability, cut HCFCs indirect material 125.1 tons, obsolete such products, the destruction of the ozone layer material and reduce greenhouse gas emissions, to protect the common human survival environment has a positive meaning.
