Evaporative condenser used in air conditioning refrigeration system
2021 / 12 / 17
In recent years, our country has the evaporative condenser are applied to all kinds of refrigeration system, including cold storage, central air conditioning, industrial refrigeration units, ammonia refrigeration system, etc. And early in the 1970 s, developed countries began to use an evaporative condenser instead of water cooled condenser. Relative to the traditional way of condenser, the evaporative condenser has the following advantages: one, the energy conservation as air-cooled condenser cooling capacity is limited by environmental dry bulb temperature, wet bulb temperature and the evaporative condenser is limited by the environment, and the wet bulb temperature 8 ~ 14 ℃ lower than the general dry bulb temperature, combined with upper fan equipment negative pressure caused by the environment, so compared with air cooling condenser, evaporative condenser condensation temperature is low. And condensing temperature rise per 1 ℃, the refrigerating capacity of the unit power consumption will increase by 3% ~ 3%, so the total power consumption of evaporative condenser will be significantly reduced, energy saving effect is obvious. In the air conditioning refrigeration system relative to other condenser can be energy-saving 20% ~ 40%. Second, the water evaporative condenser make full use of the latent heat of vaporization of water, the general water cooled condenser cooling water every 1 kg can take 16.75 ~ 25.12 KJ heat, and 1 kg of water evaporation at room temperature can take away heat about 2428 KJ, and theory of evaporative condenser water consumption is only 1% of the water cooled condenser, considering the spatter loss, pollution in water and other factors, the actual water consumption is about 5% ~ 10% of water cooled. Evaporative condenser greatly reduce the loss of water, the serious shortage of water resources in China's northern region has important significance. Thre
Refrigeration compressor system's core component technology development present
2021 / 12 / 17
In recent years, as the core components of the compressor refrigeration system, in addition to own performance improving, its research and development has been around two topics, environmental protection and energy saving technology development mainly has the following several aspects. A, adapt to the change of the refrigerant Damage to the ozone layer has a role of CFCs and HCFCs refrigerants, eliminated the material is specified by the Montreal protocol, in the late 1980 s began to gradually replaced by HFCs and natural working substance. Compressor in order to meet the alternative refrigerants and the considerable improvement in technology, developed everything, R404A, R410A and R407C HFCs refrigerant compressor, such as refrigerant compressor and R600a and R290 HCs class. CO2 across critical cycle with compressor has been successfully used in automobile air conditioning and heat pump water heater, the average CO2 compressor and NH3 cascade system is used in commercial refrigeration, enclosed NH3 compressor is used in air conditioners and refrigerators. Second, the frequency conversion technology and digital vortex. Compressor stepless regulating capacity in a row, to better match the refrigeration unit load changes, effectively improve the whole working efficiency and adaptability of the unit. Frequency conversion rolling piston and whirlpools compressor has been widely used in all kinds of air conditioning unit, the frequency conversion technology is expanding its application to the piston, screw and centrifugal compressor, refrigerator with frequency conversion piston compressor production also gradually expanding. In September 2008 in China promulgated the new air-conditioning energy efficiency standards will further stimulate the development of frequency conversion technology. Mechanical continuously variable volume of
