在空壓機行業(yè)上下瘋狂追逐設(shè)備能效的同時，通過空壓機余熱回收，提高能源再次利用率已被提上很多企業(yè)的工作日程。
In the air compressor industry crazy pursuit of energy efficiency at the same time, through the air compressor waste heat recovery, improve energy re utilization rate has been put on the agenda of many enterprises.
根據(jù)美國能源署統(tǒng)計，壓縮機在運行時，真正用于增加空氣勢能所消耗的電能，在空壓機總耗電量中只占很小的一部分約為15%，大約85%的電能轉(zhuǎn)化為熱量，通過風(fēng)冷或者水冷的方式排放到空氣中。這些“多余”熱量被排放到空氣中，既影響了環(huán)境，加劇大氣“溫室效應(yīng)”，制造了“熱”污染，同時這些熱量被白白浪費，而這些損失的熱量中有80%是可以被回收利用的，折合壓縮機的軸功率約為60-70%。
According to the statistics of the United States Energy Agency, when the compressor is in operation, the electric energy that is really used to increase the potential energy of the air compressor only accounts for a small part of the total power consumption of the air compressor, about 85% of the electric energy is converted into heat and discharged into the air through air cooling or water cooling. These "excess" heat is discharged into the air, which not only affects the environment, intensifies the "greenhouse effect" of the atmosphere, but also creates "heat" pollution. At the same time, the heat is wasted in vain. 80% of the heat loss can be recycled, which is equivalent to 60-70% of the compressor shaft power.
空壓機余熱回收的主角通常是空壓機熱能熱水機組，它是一種利用壓縮機高溫油氣熱能，通過熱交換將熱能充分利用的節(jié)能設(shè)備。通過能量交換和節(jié)能控制，收集空壓機運行過程中產(chǎn)生的熱能，同時改善空壓機的運行工況，是一種相對高效廢熱利用、零成本運行的節(jié)能設(shè)備。
The protagonist of air compressor waste heat recovery is usually the air compressor thermal water heater unit. It is an energy-saving equipment that uses the high-temperature oil and gas heat energy of the compressor and makes full use of the heat energy through heat exchange. Through energy exchange and energy-saving control, the heat energy generated during the operation of the air compressor is collected, and the operation condition of the air compressor is improved. It is a relatively high-efficiency waste heat utilization and zero cost operation energy-saving equipment.
