Refrigerant alternative trend

refrigeration has always been attached great importance to the question, hvac industry refrigerant instead become a hot question now. In the '2015 annual meeting of China's hvac industry to carry out', the ministry of foreign cooperation base director Mr Zhi-feng zhong at first we introduced the domestic and the world trend of the refrigerant replace '. PM2 now. May become a very serious pollution in our country, but with ozone is really let us feel headache. PM2。 Ozone 5 pollution control and eliminate, but to some extent related to PM2. 5 difficult. But for a long time living in PM2. 5 environment, your lungs and respiratory system by loss, but you don't die instantly. In a very primary factor is the ozone, ozone if say to must have height of cent, or high concentration of contrast, the suitable environment condition contrast, for example, we in the high temperature in Beijing, the ozone layer gathered must degree, will gradually become pale blue, the air smog is formed. So the ozone in close formation, high concentration is a kind of evil. But the low ozone concentration is a disaster for us. After the destruction of the ozone layer the lowest one damage is photochemical smog, is actually absorb ultraviolet light, ozone formation. If say there is no protection, of the lower level, the concentration of the troposphere, the result of photochemical smog. The second damage is human's health, because human beings have not resist mechanism, for example a cataract, skin cancer, sunburn. The most serious consequence is destroying all the ecological, eventually survive is also know that some microbes live in the earth.

so formed to protect the ozone layer of the world's environmental treaties, including the Vienna treaty in 1985, the Montreal protocol in 1987, in 2007, the Chinese to complete the selection of CFC's two and a half years, completed the first phase of the performance of the mission. This phase of the mission is now as and screening of HFC and cutting. As is a very good refrigerant, we know the refrigerant is in high temperature and high pressure to very low temperatures rarely have this kind of material can resist high temperature is such a great pressure and temperature drop without decomposition, so this kind of thing is very safe. Let's see the green of this picture is used as screening schedule, in 7 years in September, the 19th the Montreal protocol on the conference of the parties through the selection of speed adjustment of HCFCs material. From the point of the situation, is exceeded, now estimate should be at the levels of 11% to 15%, must be more than 10%.

in the process of all as happens to be a process of from the damage to the protection, also is the process of refrigerant evolution. Once in ten years, the developed countries choose to replace, the time not cause our attention, is to as. In various ways, are not allowed to use high GWP. So this is the trend of the so-called, is irreversible. Why should we cut HFC? One is the greenhouse effect ozeme depletion potential is too high, the second reason is that the growth rate of HFC too fast, completely is not controllable speed in add.

why do environmental protection departments to think about the matter of time to cut high GWP, try to use natural working substance. Under certain conditions, had to transition conditions, with low GWP transition. Of course there are some very special category, for example some HFC military demand, some requirements for medical category HFC, air conditioning equipment is not demand HFC. From the nation's security. Other local cannot have the dose of fluoride.

also attaches great importance to our country, some time ago we dealt with a top level design of ecological civilization. Also actively promote the cooperation together, has been to Beijing from the center of the APEC meeting will HFC reduction issues included in the review, has repeatedly announced a joint statement. Some of the European Union, the United States and other developed countries have a ready-made some guidelines. In addition under the Montreal protocol HFC is a very hot issue. HCF is cut, rather than screening, each country has put forward the proposal, and that 15% is for military, fire control, medical, won't consider air conditioning industry. This is a big challenge for us, until today, we are also being forced to deal with, others say this is good, let's say this is good. Others say this can't, we also feel this. Together, is also a difficult on every opportunity. The industry for so many years since, it is only a guideline reversed transmission mechanism, used to be reversed transmission technology policy. Is not to say that because of environmental protection, but the technology to carry out it must go. So, this is a very big opportunity, for us is the only one policy leads to the condition of the mechanism, we will steadfastly study some things. We need close attention to the world the consultation, and to analyze the disadvantages of various proposals on our.

home shopping mall, first is R290 market promotion.

let's do a room air conditioner shortly before its green low carbon conference, introduced the effect, simple to this logo we gave the expectations. Haier, gree air-conditioning manufacturers such as did the entire line product planning, also announced the promotion plan of the first half of 2016. We also organized a government takeover, the government in shenzhen university. Especially under the condition of the market downturn this year to get such a result is still satisfactory. Let's do heat pump demonstration projects, the first is to the north to demonstrate the use of heat pump of coal cuts.
