*节能好 Outstanding energy-saving effect
The heat conduction coefficient of aluminum is 120W(m2.℃),and iron,46W(m2.℃),By this token,the heat conduction coefficient of aluminum is 4.56times larger than that of iron.The lower limit temperature of aluminun alloy is -269℃,and seamless steel tube,-29℃.By this token,aluminum coil can save 30%.more energy than iron coil,and
it has better heat conduction and higher refrigeration speed,and is more suitable for low-temperature environment.
*重量轻安装方便 Light weight ,convenient installation
The piojecting and evaporation area of aluminum coil can reach1:3or1:4.The ideal refrigeration effect can be realized when aluminum coil is mounted on the top of refrigerating house .For it is light in weight and convenient in installation,labor and time is saved,structural stability is ensured and construction cost is reduced.
*增加库容量 lncreased capacity
For the aluminum coil is mounted on the top and there is no need to install wall coil around the house ,this unique design increase the capacity and utilization ration of refrigerating house.
*制冷剂用量小、节约成本 Low refrigerant consumption,reduced cost
Fof the same refrigeration capacity.the required aluminun tube is shorter than iron coil,therefore the charging quantity of refrigerant is small,which economizes the cost and gets better refrigeration effect.
*食品干耗少 Low weight loss of food
The weight loss of food gets maximal when compressor is functioning,and drops after shutdown.Fof temperature-drop speed of aluminum coil is very fast.working duration of compressof is short and shutdown duration is long ,compared with traditional iron-coil of air -cooler refrigerating house,there is less weight loss and the fresh-keeping effect will be better.
*易除霜 Easy to defrost
Basically there is no frost or only a few frost on the aluminum coil of large-scale refrigerating house,therefore,it is easy to defrost,and constant temperature and humidity effect is good.
*延长机组使用寿命 Extended service life of compressor unit
Treated by acid sand and oxidation process,the inner wall is clean and smooth without oil stain,it can resist corrosion and will ont be oxidized for 20 years,which complies with food hygiene standard and effectively extends the service life of compressor unit.
