Hitachi compressor 750EH-128D3 With industrial development with the resulting pollution of the Earth is getting worse, environmental protection has become an important issue of global concern, and to prevent the destruction of the ozone layer and global warming is causing the world widespread national attention, and to the international community to reach a consensus between the government and signed the relevant agreement. Hitachi compressor 750EH-128D3 and in the field of refrigeration and air conditioning CFCS and HCFCS of atmospheric ozone layer and global warming caused by energy consumption are compressor compressor design should attach great importance to the issue. Hitachi compressor 750EH-128D3 is well known that the choice of refrigerant compressor design is the impact of the many factors that should be a high priority. In order to develop the use of alternative refrigerants new compressor, the designer first encounter two problems: First, Hitachi compressor 750EH-128D3 must put the size of its working volume redrawn to accommodate different flow pressure requirements; their Second, Hitachi compressor 750EH-128D3 in contact with the refrigerant compatibility between various materials, such as synthetic rubber and lubricating oils, must be given address. Hitachi compressor 750EH-128D3 in past history, there are more than fifty kinds of substances have been used as refrigerants. After World War II, in addition to a large amount of cold ammonia is also used outside of the range, almost all areas of refrigeration and air conditioning have been dominated by halogenated CFCS and HCFCS, 1974 Montreal Agreement as specified in the CFCS alternative in industrialized countries achieve, and HCFCS alternative plan will be completed in 2020; while the developing countries will be respectively in 2010 and 2040 disabled. However, in some developed countries are ready ahead of schedule. Figure 6 shows a common European original CFC-11, CFC-12, HCFC-22 and R502 may use applications and the replacement agent (horizontal arrows below). Hitachi compressor 750EH-128D3 growing in the current energy crisis, energy transformed into reducing energy consumption, the best way to ease the crisis. Admittedly, technological innovation to spend considerable human, material and financial resources, but compared to the success of energy-saving bring results, but a drop in the bucket spend. Saving technological transformation in the national advocate of the environment, as closely related to the HVAC industry and energy need to examine. How to achieve the greatest degree of energy-saving and new development opportunity has come, HVAC refrigeration industry needs to seize in order to accomplish a great deal. Hitachi compressor 750EH-128D3 along, foreign brands in the domestic central air-conditioning market occupy most of the market share of domestic brands long-term disadvantage. Attributed reason is simply foreign brands with a strong brand pull with advanced technologies. The local brand is focused on channel development, in a given period, the advantage can not be highlighted. Through years of market operation, advantages and disadvantages of two routes gradually revealed. Foreign brands despite the very strong rally in the brand, but the price is expensive. Domestic consumers become more rational, no longer simply superstitious power of the brand, the choice of the central air-conditioning more attention to its cost. While local brands intensive sectors in the channel also entered the harvest period, more and more obvious advantages, the use of existing retail channels to promote central air conditioning also allows foreign brands Wangyangxingtan Phone: 18998013185 QQ: 415819311 Contact: Luo Lifeng cold storage Price: http: / / www.lengku1.com/ Hitachi compressor: http://www.hitachizg.com/ Hitachi inverter compressor: http://www.fuyid.com/ Hisense Hitachi compressor: http://www.fuyid1. com / Hitachi inverter compressor: http://www.fuyidg.com/ Hitachi cooled unit: http://www.hitach1.com/
