Refrigerant substitution integration situation home and abroad

refrigeration has been the hvac professional pays attention to the question, the refrigerant instead of a hot question now. In the '2015 annual meeting of China's hvac industry', 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 '.

zhi-feng zhong, said Mr PM2 today. May become a very serious pollution in China, but ozone is bugged real let's together. 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 losses, but not immediately, died. In a very primary factor is the ozone, ozone if say to must have a high degree of cent, perhaps concentration is high, the more suitable for the conditions of environment, for example we in Beijing in the high temperature, the extent of the collection to the ozone layer will be, the air will gradually become a light blue, the haze is constituted. So the ozone in close formation, high concentration is a kind of evil. But the low ozone concentration is a disaster for us. The ozone layer is damaged after a minimum damage is photochemical smog, in fact is to absorb ultraviolet light, ozone. If say there is no defense, down to a layer, the concentration of the troposphere, eventually forming the photochemical smog. The second damage is the health of human beings, the human did not resist mechanism, for example cataract, skin cancer, sunburn. All the most serious is the result of the damage to the ecological, eventually survive is also know that some microbes live in the earth.

so constitutes the world convention of maintenance of the ozone layer, contain the Vienna convention in 1985 and 1987, the Montreal protocol, in 2007, two and a half years ahead of China completed the CFC screening, finished the first during the performance of the mission. Now is the mission of this period 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 stress and such big temperature drop without differentiation, 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 on the conference of the parties by the Montreal protocol, to speed up the screening of HCFCs adjustment case material. From the perspective of the status of today, it is exceeded, now measure should be at the levels of 11% to 15%, affirmation is beyond 10%.

in the performance of all as the course of the just is a damage to the maintenance process, also is the process of refrigerant evolution. Once in ten years, the developed countries choose to replace, we pay attention to the time did not cause, is to as. In various ways, I don't promise to use the high GWP. So this is the trend of the so-called, is irreversible. Why we have to cut our 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 the environmental protection department in thinking about the matter of time we had to cut off the high GWP, try choosing 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.

our country also pays attention to, some time ago we dealt with a program on the top of the ecological civilization. Also active to promote world collaboration together, from the beginning to the APEC meeting in Beijing will be HFC reduction issues in comments, repeatedly issued 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, air conditioning profession not thinking. This to us is an endless battle, until today we are in a passive perfunctory, others say this is good, let's say this is good. Others say this, we also think about this. Together, is also a difficult on every opportunity. This career for so many years since, it is only a policy reversed transmission mechanism, once skills are reversed transmission principle. Is not to say that due to the environmental protection, but it is necessary to go on this skill. So, this is a very big opportunity, for us is the only time the status of the policy making 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 mall.

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 implementation of the scheme in 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 results are satisfactory. Let's do heat pump demonstration projects, the first is the northern region to demonstrate the heat pump about cut down the use of coal.
