DOMESTIC HYDROFLUORIC ACID MARKET PRICE IS RISING DEC.13th,2017

On Dec. 13, the mainstream price of domestic anhydrous hydrofluoric acid manufacturers was

RMB 12000-13000/ ton, ex-factory prices of some factories increased, but the operating rates

of hydrofluoric acid manufacturers did not change much, and the supply of goods in the

venue was slightly tense. Market prices rose slightly.

On Dec. 13, the index of hydrofluoric acid was 112.19, up 1.07 points against yesterday's day,

down 6.53% from the highest point of 120.03 (2017-10-22) in the cycle and slightly up from

the lowest of 53.59 points of Nov 30/2016 109.35%. (Note: the cycle refers to 2011-09-01 so far)

R134A IS IN HARD PROGRESS

R134A is a widely used refrigerant. It does not contain chlorine atoms and does not destroy the ozone layer. It has good comprehensive performance. The market demand for R134A has also continued to rise in recent years. But I think the rise is transient. The growth of R134A will last until 2022, then slide down, then disappear in the market and be replaced by other products. Although R134A refrigerants have good comprehensive performance and no harm to ozone, the greenhouse effect caused by high GWP is the biggest defect. Both Europe and the United States have already made a corresponding control over the high GWP refrigerants. The United States Environmental Protection Agency (EPA) will prohibit the use of high GWP refrigerants, including R404A, R134a, R407C and R410A, in some new products from January 1, 2021.

R134a, R125 and R32 are the third generation refrigerants. Because of their high GWP, they are the products to be eliminated. Based on the Montreal agreement reached in 16 years, the HCFs roadmap for the elimination of developed and developing countries has been developed globally.

HFCS CUT CONTRIBUTES TO SUSTAINABLE DEVELOPMENT dec.11th,2017

Recent survey released by the world's leading academic journal Nature Climate Change shows that cutting HFCs and other short-term climate pollutants (SLCPs) can help reduce the effects of climate change, reduce hunger and poverty and contribute to the world Countries achieve the 17 Sustainable Development Goals (SDGs) proposed by the United Nations.

Among the 17 Sustainable Development Goals, top priority is poverty eradication. Cutting energy costs indirectly contributes to this goal, and researchers see cuts in HFCs as a way to reduce energy costs.

The second goal of the Sustainable Development Goals is to eradicate hunger. Researchers believe that reducing HFCs and improving cooling efficiency can increase the affordability of refrigeration and reduce food waste, which in turn helps to eliminate the hunger target.

They cite several recent case studies: In commercial food stores, equipment that uses propane or other low-GWP refrigerants can save up to 30%.

Reducing short-term climatic pollutants such as HFCs under the international conventions such as the Kigali Amendment to the Montreal Protocol contributes to the thirteenth goal of the Sustainable Development Goals - mitigation of climate change. The Kigali Amendment is expected to avoid a global warming of 0.5 degrees Celsius in the world.

"Governments have promised to achieve their climate change mitigation goals and they are committed to achieving the Sustainable Development Goals, but there is often limited awareness of the linkages between them," said co-author of the report, Drew, professor of climate sciences at Duke University in the United States Shindell said.

The report concludes that cutting HFCs also contributes to the achievement of other sustainable development goals such as quality education, decent work and economic growth, responsible consumption and production, sustainable cities and communities.

USA:AUTO REPAIR NEEDS LICENSE TO PURCHASE REFRIGERANT FROM NEXT YEAR DEC.13TH,2017

It is reported that the EPA Certificate 609 will add more value in the new year. From January 1.2018, Certificates 609 need show up to purchase refrigerants, such as R134a, HFO-1234yf. Originally, this requirement was enforced only for R12 and is now equally applicable for the purchase of new refrigerants.

Certificate 609 needed for purchasing 2 LB or more quantity refrigerant. Tim Zilke, chief executive officer and president of ASE said, the EPA requires maintenance technicians have the qualification of Certificate 609 unit to serve the Automotive Air Conditioning (MVAC) system.

Professional service person needs show the certificate to buy refrigerant. Refrigerant distributors and wholesaler need keep nearly three years of refrigerant transaction records.

The certificate 609 is available through the EPA-approved ASE Refrigerant Recovery and Recycling Program. For convenience, ASE advises technicians to obtain a certificate online for immediate results. The cost of the certificate is $ 19.

HOW TO AVOID FAILURE when INDUSTRIAL CHILLER COOLING TEMPERATURE DROP

When industrial chillers are used, industrial chillers can not reduce the ambient temperature even after a long period of operation if industrial chillers suffer from various malfunctions. In order to reduce the time that the enterprise waits for the equipment to run, the best low-temperature environment can be obtained by increasing the temperature drop rate of the industrial chiller to meet all the needs of the enterprise production.

If long-running industrial chillers are also unable to obtain a suitable low-temperature environment, then for industrial enterprises, industrial chillers may be more serious failure. The industrial chiller is usually operated in a fault state, which not only istes precious energy, but also causes the decreasing speed of the ambient temperature to drop continuously, affecting the normal production of the enterprise in the later period.

The rate of temperature drop is reduced, which is related to the cooling effect. If the industrial chiller releases the low temperature gas, the more time it takes to reduce the temperature. Under normal circumstances, enterprises in the choice of industrial chillers, according to the specific size of the space to choose. If the sudden drop in the cooling effect of the problem, the need for timely enterprise-wide industrial chiller for testing, to ensure the safety and stability of the operation of the equipment. Encounter industrial chiller appear cooling rate decline, as the first choice for enterprises need to carefully check the equipment for the existence of failure. The main cause of the low temperature failure of industrial chillers usually is the decrease of sealing performance. If the environment of the sealing effect is poor, may result in the continuous loss of low-temperature gas, even if prolonged use of industrial chillers also can not get a better low-temperature environment.

If the industrial chiller evaporator failure, the same will cause the industrial chiller cooling performance decline. As long as the enterprise can find the main reason that affects the cooling performance, the enterprise can maintain the stable operation of the industrial chiller equipment, reduce the energy consumption of the equipment operation, and provide the suitable low-temperature production environment for the enterprise in a short time.

Industrial chiller failure is inevitable, in order to get the best results, companies operating industrial chillers, the need for regular equipment for a comprehensive maintenance and care. Industrial chiller can promptly find the existence of a variety of failures, and maintenance, can improve the operating efficiency of industrial chillers, rapid realization of the purpose of reducing the ambient temperature.

HOW TO OPERATE COLD STORAGE DISTRIBUTION BOX WHEN IN THE INSTALLATION OF COLD STORAGE?

Cold storage installation process, the use of cold storage distribution box is a very important part, but most people are not familiar with the normal operation of the cold storage distribution box, and today we follow the refrigeration experts to understand cold storage distribution Box of the correct method of operation.

After the cold storage installation, the wiring outside the cold storage distribution box must be protected by the correct method. For example, some of the steel tube hoses should be placed in a place that is not easily damaged, otherwise it may lead to Cold storage distribution box wiring suffered unnecessary damage.

Cold storage installation, distribution box machine power cord between the best is placed in the middle of the bridge, the bridge also need to use the base to play a supporting role, Cui Hua said the proposed use of the bridge, it is not and Direct contact with the ground.

Piping outside the distribution box also need to be unified, which is an important part of the cold storage installation. If there is no uniform phenomenon, then in the latter part of the use of regular fault problems will occur, a waste of our unnecessary maintenance costs, and I hope everyone should grasp. Cold storage installation, the distribution box packing machine or other heating equipment connection needs attention, when the wiring, you need to stay away from near the heating, the wiring is best placed in the connection box inside, the heater connection is best Use glass or ceramic tube wire, for safety can not use flammable wire.

Outside the cold storage distribution box so the wires are connected at the time of the need to connect the box, which is an important part of the cold storage installation process, in addition, the middle of the cable can not have joints. Cold box distribution box All the connection boxes, cable entry protection levels, all of which require more than IP55 standards, which is cold storage installation we need to pay attention to a content.

Relay terminal block is best to use two wires to link, if you need to link more than three wires, it is best to set the other terminal block, or it will affect the normal use of the distribution box. Sensor placed in the wiring easy to damage the place, it is best to use the hose to play a protective role, the use of the hose, preferably placed directly on the sensor's root, this one is also cold storage installation Need to pay attention. At the same time, after the cold storage is installed, the normal use of the distribution box needs to be checked regularly. Once the hidden danger arises, it must be disposed in the first time, otherwise it will affect the normal use and may even cause economic loss. Hope We must pay attention to inspection.

The above is the cold storage installation of the correct operation of the distribution box knowledge, in order to make the role of distribution box can be normal, we need to pay attention to some of these elements together. This normal use of cold storage will play a supporting role.
