It is very popular for large masses of users. It is not only mainly used in steel structure plant, logistics warehouse, farm and other large enterprise buildings, but also agricultural markets, gymnasiums, waiting rooms, exhibition halls and other large public buildings. A large energy-saving ceiling fans with a speed of 50 revolutions per minute 1 to 3 meters per second to make the human body feels the best wind speed. A breeze from all directions gently caresses the body and increases the evaporation of human sweat. The cooling effect of 5 to 8 degrees is similar to the comfort presented by the natural breeze, which can not be matched by other fans. It is an ideal choice for indoor, ventilation and cooling in summer to remove humidity and heat. Only seven degrees of electricity per day, it can be cool for a whole summer. Energy saving comparation In summer, the sun shines directly and the indoor temperature is more than 40 degrees on average. Common industrial exhaust fans can only increase the indoor temperature. Industrial air conditioners consume thousands of kilowatts of energy every shift. There is no obvious unenclosed cooling in the space, which also increases the operating cost of enterprises. The emergence of a large energy saving ceiling fan brought the perfect solution. An energy saving fan with a diameter of 7.2meters can push the air to produce a large amount of winds effectively. The continuously rotating blades of circular form an airflow field with an effective area of 600 to 800 square meters. No other device has not yet been compared. The large energy-saving ceiling fan praduced by Linter technology has the characteristics of high reliability, feasibility and low power consumption. The controller unit used the stability of the energy-saving inverter system. In practice, the average power consumption is less than one killowatt per hour. It can guarantee more than 5,000 hours of uninterrupted operation. Linter7200 of a large energy-saving ceiling fan can cover the area of about 50 small fans of 0.75 megabytes worked. In a factory of 9000 square meters, if full coverage is to be achieved, it needs about 300 small fans or industrial 6 energy-saving fans. According to the use of four years, every eight months, every day for ten hours, can be run for 10,000 hours, about 90000kw power consumption, than the small wind 1080000kw, save 990000kw, save energy by 92%. When meeting the extreme high temperature climate, the large energy saving fans and air conditioners are used together, it will be coller. Using A large energy-saving ceiling fan for air supply can not only save the air conditioning tube, but also save more than 30% energy. Attentio Lectotype The building structure: H-shaped steel, I-shaped steel, Mixed steel square bar spherical column spherical structure. The total height of the building is more than 4, 0m, less than 15m. 1, 0m. The minimum distance between the fan and the roof is 1, 0m. The minimum safety distance between the fan blades and the obstacle is 0, 3 m. The distance between the fan blades and the wall on both sides is more than 1, 5 m. Effects of various environments on fan performance. Open space, promotes air circulation. Indoor airflow circulation in enclosed spaces is suitable for use with air conditioning. In a multi-fan environment, due to the low wind speed, caused by the fan, there will be no cyclones. The distance between the two fans will be separated before the wind will not cancel, and the coverage area will be increased at the same time.

As the change rate of crude oil in the three places turned upwards, the expectation of lowering domestic prices of gasoline and diesel in early September has already been frustrated. According to the statistics report of the refined oil market monitoring agency on September 13, in the first week of September, the wholesale prices of PetroChina and Sinopec rose by a large margin, with an average increase of between 100 yuan and 150 yuan/ton.
Driven by the rise in crude oil and the expected recovery in diesel demand in September, some traders began to replenish. In this regard, analysts believe that although the diesel market speculation and excessive replenishment demand, but the recurrence of diesel shortage is unlikely.
The wholesale price of diesel rose by more than one hundred yuan per ton. According to the latest monitoring of Zhuo Chuang Information, in the first week of September, the prices of domestic main gasoline and diesel oil have all increased in different ranges. Among them, the increase in diesel prices is relatively large, with an average increase of 100 yuan. Between 150 yuan / ton.
The analyst Li Qian believes that in August and September, PetroChina and Sinopec are the two major refinery maintenance peaks. Since September, the shortage of diesel resources and the weakening of the oil price forecast by the Development and Reform Commission are the reasons for the slight increase in gasoline and diesel prices. one.
Recently, the international oil price has continued to fluctuate, resulting in an increase in the proportion of middle-to-high prices in the 22-day average price of crude oil in the three places. The rate of change in crude oil in the three places continues to rise. As of September 12, the rate of change in the three places has risen. To -1.66%.
Zhu Huichun, an analyst at Zhuo Chuang, predicts that if the international oil prices continue to fluctuate in the near future, the rate of change in the three places may turn positive in the middle or late September; even if the international oil prices continue to fluctuate in recent days (falling within 5 US dollars/barrel), the three places The rate of change is also difficult to fall to -4% within this month. Therefore, it is difficult to open the downward adjustment window. The forecast for the price cut for domestic gasoline and diesel in September may be frustrated.
International crude oil rebounded. Domestic refined oil prices stopped falling and showed signs of rising. Analysts at the China National Petroleum Institute of Economics and Technology said that due to the low domestic start-up load of the refinery for several consecutive months, and the low inventory of petrochemical projects, the market supply was not well-supplied in September, and some major units in North China and East China started to enter moderate levels after September. Push price, diesel push up is more obvious.
According to the research conducted by Siwang Energy, as of September 8, the 35 main refinery operating rates continued to decline by 0.51 percentage points from the previous two weeks to 79.66%, still the second lowest level this year, compared to the history of late May this year. The highest point fell sharply by 8.3%, and there was also a 5.7% drop from the same period last year.
Since June, the enthusiasm of domestic refineries has been low, coupled with frequent inspections and frequent accidents, and refined oil inventories are still decreasing. As of the end of July, refined oil inventories fell by 5.47%. Gasoline was down 5% from the previous month and diesel was down 5.4% from the previous month.
Hu Huichun said that this month's petrochemical petrochemical diesel deployment plan has been significantly reduced, even in some areas highlight the tense diesel, boosted by rising crude oil prices will be willing to push, the majority of domestic main wholesale diesel prices have risen above the wholesale limit price , but there is still some distance from the retail price limit.
The demand for diesel speculation may erupt again. “Most traders have no hope for the recent price adjustment. The market will be more confused after the price adjustment hopelessness, but some traders will start to replenish.†Analysts at the China National Petroleum Institute of Economics and Technology said that there is no hope of price adjustment in the short term. The domestic market mentality is no longer just waiting to see, traders operate to normal, although there is no speculative purchase, but the normal seasonal demand pick-up can also drive diesel fundamentals to strengthen.
Treasurer Island market analyst Han Jingyuan said: “After the Mid-Autumn Festival holiday, the overall bullish mentality is still continuing. The demand for diesel terminal will gradually increase in the later period. Coupled with the approaching National Day holiday, replenishment enthusiasm will be difficult to dissipate.â€
"Similar to the same period of last year, the recent international oil prices have again shown signs of sudden rises, and sudden bursts of speculative demand may repeat itself." Han Jingyuan believes that during the busy season of diesel demand in September, there was no surprise that diesel supply shortages occurred in some regions.
Due to the early reduction of diesel import tariffs, plus the rate of refinery start-ups of the two major companies will rebound at the end of September, it is expected that the diesel shortage will not occur again. The fluctuations in the expected fluctuations in the supply and demand side of domestic gasoline will not be too great, and the market sentiment may be boosted by the higher diesel market.
