Air conditioning industry: refrigerant alternative parallel direction-www.3122.com-澳门太阳集团2017

  About a new generation of refrigerant replacement, has now become the hottest ic in China refrigeration and air conditioning industry. This is mainly because:

  1, 2016, is China's hydrogen CFCS (HCFCs) work out formally entered the second phase of the beginning. During the period of 2016-2020, China will eliminate 35% of the production and consumption of HCFCs (2009-2010 with an average production and consumption of the benchmark), that compared with the first phase of the eliminated 10%, is a has quickened significantly.

  2, the European Union and the United States have been issued relevant laws and regulations, and is the implementation of HFC (HFCs), has led to reduce HFCs application development trend in the world.

  And also conform to the trend, China is actively involved in the international community (developing countries) about HFCs into the Montreal protocol to control and eliminate the discussion in the meeting.

  Under such pressure, the domestic refrigeration and air conditioning industry upgrade is speeding up its replacement. To this, the west learned the CCM in the multiple direction is parallel development.

  Natural refrigerant substance by the national support

  Environmental protection international cooperation center in June 2015 issued earlier in the catalogue of a batch of HCFCs key to replace former recommended (draft) ". Among them, the recommended alternatives in the refrigeration and air conditioning industry mainly includes the propane (R290), isobutane (R600a), carbon dioxide (CO2) and ammonia (NH3), etc.

  According to the west the CCM to understand, the first batch of recommended directory is expected to be officially released in the first half of 2016; Plus since January 1, 2016, the use of flammable refrigerants room air conditioner installation, maintenance and transportation technology requirements implemented (QB/T4835-2015), as well as for R290 air-conditioning production safety standards, transportation and storage standards expected by the end of 2016 or published in 2017, these are marked country is to promote the popularization application of refrigerant natural working substance.

  With national pace and domestic air conditioning manufacturers, in 2015 completed the 17 R290 air-conditioning production line modification, have launched R290 air conditioning; Similarly, other applications, such as R600a refrigerator freezer has gradually popularization, the CO2 air can heat pump, NH3 cold storage and other applications is growing.

  About a new generation of refrigerant replacement, has now become the hottest ic in China refrigeration and air conditioning industry. This is mainly because:

  1, 2016, is China's hydrogen CFCS (HCFCs) work out formally entered the second phase of the beginning. During the period of 2016-2020, China will eliminate 35% of the production and consumption of HCFCs (2009-2010 with an average production and consumption of the benchmark), that compared with the first phase of the eliminated 10%, is a has quickened significantly.

  In the above HCFCs focus on a number of recommended directory, replace former although most of these substance are natural refrigerants, but actually also includes only a fluoride refrigerants, HFC - 32. This also to those who hold the natural refrigerant substance security risk is bigger, and more inclined to continue using fluoride air-conditioning manufacturers alternative technologies, from the choice of direction.

  West understands the CCM, HFC - 32 with the current mainstream of the application of R410a (HFC - 32 (HFC - 125) and five fluorine ethane mixed) by 1:1 proportion compared with the former global warming ozeme depletion potential (GWP) is lower; And in the same condition, and the compressor, and under the condition of operating frequency, the refrigerating capacity of the former and can effect comparing higher about 5% than the latter.

  The fourth generation of hydrogen fluoride olefins (HFOs) refrigerant development is speeding up

  According to west CCM, realized in the downstream market demand has not yet formed under the premise of the current domestic have according to the batch production HFOs refrigerants is changshu three love rich ZhongHao chemical new material co., LTD. Mainly because it is with the branch company (the original dupont fluorine chemicals, science and technology of titanium white and specialty chemicals division of cooperation and related products is the main supply branch company for the sale of European and American markets.

  Three love rich ZhongHao has confirm the 2,3,3,3 - four fluorine propylene (HFO - 1234 - yf) and 1,1,1,4,4,4 - six fluorine butene (HFO - 1336 MZZ) project. Among them: - HFO - 1234 - yf capacity 3000 tons/year, a phase of the project was established in early 2013 reaches producing; Construction of phase ii in 2015 production capacity of 3000 tons/year - HFO - 1336 MZZ project production capacity of 5000 tons/year, start in November 2015

  But since 2016, the domestic about HFOs refrigerant production technology accumulation and technology stocks are continuously made new progress.

  In April 2016, for example, honeywell announced JuHua group co., LTD., authorized the production HFO - 1234 - yf in China.

  At the same time, shandong dongyue chemical co., LTD and shandong hua an new material co., LTD., also through the development of research, master the HFOs refrigerant production technology, which can realize the production of related products.

  But at this stage due to patent restrictions, domestic manufacturers want to participate in the HFOs market management, follow-up still need through the authorized cooperation way.
