gas-cooler
2.Variations of beth evaporating temperature and gas-cooler exit temperature have strong impacts on the EER of the system.
3.Its current products include: top oscillation electrical precipitator,side electrical oscillation precipitator, magnetism controlled static electricity precipitator, wet electrical precipitator, honeycomb electric catching tar instrument, high-pressur silicon rectifier equipment and PLC low-pressure controlling system, blast furnace gas impulse precipitator, high concentration pulverized coal collector, coke oven and boiler flue gas low pressure impulse precipitator, blower fan inhaler,crossing piping gas cooler, high temperature fume cooler,gyre-orientation impulse hop-pocker and all sorts of molded sections.
5.The relationship between the compressor efficiency and compression ratio was analyzed in terms of the superheat temperature,the refrigerant temperature at the gas cooler outlet,and the high pressure on the coefficient of performance(COP) to optimize a transcritical automobile air conditioning system using carbon dioxide as refrigerant.
6.The mathematical model of the ejector in the transcritical carbon dioxide vapor-compression/ejection refrigeration cycle was established,and the effects of evaporating temperature,heat rejection pressure,gas cooler outlet temperature and the superheat on the system performance were discussed as the system works in steady status.
7.Presents the improvement of operation efficiency by choosing the proper outlet temperature of gas cooler and the discharge pressure of compressor according to the practical situation. Studies the step utilization of energy in heating system. The results show that the step utilization of heat water in heat rejection side can improve the coefficient of performance.
9.For our system, the magnet is immerged in a dewer and the upper surface of the dewer is thermally anchored to the second cold end of a two-stage pulse tube cooler with cooling power of 0.6W at 4.2K. During the cool-down process, helium gas is first liquefied by the pulse tube cooler and filled into the dewer.
