Refrigerant in 2019 under the policy of 'environmental pressure' markets

Recently, China's refrigeration industry market situation gets better, as 22 ( R22) Price is rising, which leads to the refrigerant market has the raw material supply nervous situation, cause this kind of phenomenon the reason mainly has two aspects. On the one hand, with the implement of high environmental protection policy, some inferior production capacity, lead to some enterprises have to face the production or suspend production. On the other hand, due to long-term mining fluorite resources with high quality in our country to reduce, so the cost of production is rising. Moreover, domestic fluorite have for many years to keep around 4 million tons, almost no growth, can be expected in 2019, the supply of fluorite is still nervous.

in March, the market of refrigerant is busy season, despite entering the market peak season, but the air conditioning industry overall weak demand expected. Well now R22 device production enterprise operation load performance, but because of R22 is in period of product, so stop using R22 will slowly, at the same time the proportion of R32 and r410a will gradually increase, the third generation of refrigerants were used in great quantities, such as everything. Now everything ship enterprise strong resistance, cut, even if the offer flange downstream enterprise strength is still not present. In addition, the raw material hydrofluoric acid market weakening, cost of face support weakening of everything. But recently domestic market prices rose slightly, R134a has a production enterprise device utilization, refrigerant market demand increases, the supplier is given priority to with export, but the court not clinch a deal the price change.

    In addition, due to the early stage of the aftermarket demand more flourishing, inventory a large number of production enterprises to merchants, the merchants of inventory is generally high, factory inventory is low, and the phenomenon that exists supplies. For example:

a market as a whole, the refrigerant R32 low inventory, domestic demand and export market demand are stable, factory inventory has certain growth.

2, everything device production enterprise operation load held steady overall.

3, R410a market supply, keep on-demand procurement businessmen to most.

4, R125 device production enterprise operation load level, generally keep low inventory operation.

in addition, the march production enterprise must raise expectations, it is possible that rise but the space is not large.

although refrigerants in 2018 is in the lead, but it can last long? Officials pointed out that environmental pressure in 2019 remain, fluorite, hydrofluoric acid and other raw material prices will continue to go up. In addition, by environmental protection in recent years, not the compliance of the production enterprises have been closed or rectification, the production will be more standard and stability. In addition, belongs to type as refrigerant R22, through the selection process, by 2020 will further cuts to 35% of the benchmark. But HFC refrigerant selection policy is 2020 - By 2019 in 2022 as the base year, the domestic R32, R125 capacity will be doubled. At the same time, should also be alert to second and third generation refrigerant cut down the risk of progress than expected; The third generation of refrigerant in the capacity expansion phase, there is the danger of excess capacity.

    Little knowledge

the selection of refrigerant is a complex technical and economic problems, there are many factors to consider, when the choice should be based on specific circumstances, to conduct a comprehensive technical analysis.

one, taking into account the environmental requirements: must be chosen in accordance with the state environmental protection laws and regulations of the refrigerant.

2, taking into account the coolant temperature requirements: according to different coolant temperature and cooling conditions, the selection of high temperature ( Low pressure) , medium temperature ( Medium voltage) And low temperature ( High pressure) Refrigerants. Usually choose standard of refrigerant evaporation temperature is lower than the refrigeration temperature 10 ℃. Select refrigerant refrigeration unit should also be considered the cooling conditions, using the environment etc.

3, consider the nature of the refrigerant: according to the refrigerant thermodynamic properties, physical properties and chemical properties, choose those non-toxic, no explosions, no burning of refrigerant; Choose good heat transfer, small resistance, good compatibility with refrigeration system with material refrigerants.

4, taking into account the compressor types: different refrigeration compressor working principle is different. Volume compressor through the narrow, the volume of refrigerant vapor to increase its pressure refrigerant refrigerating capacity per unit volume is big, is generally selected as everything, R22, etc.
