- product introduction:he refrigeration system in the traditional air-cooled air conditioning unit takes air as the cooling medium, dissipates heat through the heat exchange between the fan and the finned condenser, and takes away its condensation heat with air. The air-cooled finned condenser is usually of copper tube series aluminum fin structure. With the increase of service life, the heat dissipation fins are easy to embrittle and peel off under the influence of sunlight, rain and acid gas corrosion. There is adhesion between the heat dissipation fins, blocking the air duct and reducing the heat dissipation air volume, resulting in the reduction of effective heat exchange area, poor heat dissipation conditions and high condensation temperature, resulting in the decline of the refrigeration capacity of the unit, The power consumption of compressor increases and the comprehensive energy efficiency ratio of refrigeration system decreases; According to the analysis, when the condensation temperature increases by 1 ℃, the refrigerating capacity decreases by about 1.2%, the energy consumption of the compressor increases by about 1.6%, and the comprehensive energy efficiency ratio of the refrigeration system decreases by about 3%. Especially when the ambient temperature is high in summer, poor heat dissipation is easy to lead to frequent high-temperature and high-pressure protection of the compressor, which will not only affect the normal refrigeration operation of the unit, but also aggravate the mechanical wear of equipment parts and components and the aging of components, greatly shorten the service life of the equipment and report the waste in advance. The energy-saving transformation device of traditional air-cooled air conditioning unit adopts the tube to plate falling film evaporative condensation core patented technology pioneered by Aigo in the world, takes air and water as the cooling medium, and mainly uses the evaporation of water to take away the condensation heat. Because the condensation temperature of the evaporative condenser changes with the air wet bulb temperature, and the air wet bulb temperature is 6 ~ 8 ℃ lower than the dry bulb temperature under the same environmental conditions, therefore, With evaporative condensation and heat dissipation, the condensation temperature of the refrigeration system of the unit will be significantly reduced. The condensation temperature of the traditional air-cooled condensing unit is 52 ~ 55 ℃, while that of the evaporative condensing unit is 38 ~ 39 ℃. According to the corresponding relationship between the condensation temperature and the cooling capacity and input power of the compressor, the evaporative condenser is used to replace the traditional air-cooled condenser, and the comprehensive operation efficiency of the unit will be increased by more than 40%.
