The Lanzhou Petroleum Machinery Research Institute has successfully developed a surface evaporative air cooler for the first time in the world, with a production value of 400 million yuan. According to incomplete statistics, they have more than 600 surface evaporative air coolers of various specifications applied to the petroleum, chemical, metallurgical and electric power industries at home and abroad.
Ma Jun, head of surface evaporative air cooler technology, said: "This equipment can only recover the investment of equipment in one year." Surface evaporative air coolers have many advantages, such as high efficiency, under the same conditions. The cooling efficiency is more than 4 times higher than that of the old air cooler; the energy saving is more, the energy consumption can be reduced by about 30% under the same conditions, especially in line with the current demand for energy conservation; the environment is good, some old water-cooled air coolers are used every hour. Thousands of tons of water are used for cooling, and these waters are polluted, which affects the environment after discharge. The water of the surface evaporative air cooler is recycled by itself and does not discharge waste water.
