Fujian unicom: water-cooled air conditioning energy-saving and environmental protectio
2010-7-29 15:13:34
In 2010, May 13-14, the first session of the communication industry, energy saving and emission reduction conference of fujian unicom operation and maintenance department LiShiWang introduce a kind already energy-saving and environmental air conditioning cooling air conditioning. - The biggest characteristic is air cooled by water evaporation refrigeration, to absorb energy without freon. According to LiShiWang introduction, water-cooled air spring can reduce energy consumption by 50%, winter or even 90%.
Water is the core component of evaporative air filter, the evaporation of corrugated filter adopts multi-layer fiber composite, actual evaporation area is equivalent to evaporation area accounts for the filter 100 times. Rapid evaporation, and through the air and water, heat, and through the air cooling ventilation system into the room. Water-cooled air conditioning is not a new product, in some processing industries and electrical, chemical industry for over 10 years history.
According to LiShiWang introduction, January 2009, fujian, China unicom started early in the air cooling trial center room, good feeling after phased in. Using a common air conditioning cooling water, through some of the techniques of water on the part of recycling, on the one hand, to ensure room cannot fill. Water cooling air conditioning normally can be achieved by 3 to 15 degrees Celsius, the concrete temperature amplitude depends mainly on environmental humidity. The dry places, the evaporation temperature range, the better. In relative humidity for 10% of the circumstances, can reach 14 degrees Celsius temperature. For example in jinshan data in the room, the computer 380 square meters, the original air power is 8 kw, install 5 after cooling air conditioning power-consumption is 1 KWH. It has been more than a year, in addition to run 7, 8 and 9 months temperature is higher, and special use wet weather, air conditioning cooling time in operation, the effect is very obvious.
In fujian, China unicom, water-cooled air conditioning in 21 machine building 89 room 216, total installed base of transformation, air conditioning, completed 304 are currently underway to install. Actual effects, according to not complete count, 21 machine building saving electricity each month about 40 million yuan. After the reconstruction of the air base in each month, electricity saving 577 per base yuan.
The 6th national communications industry in the modern enterprise management innovation achievements appraisal, fujian unicom water-cooled air conditioning won second prize, 2009 China unicom management innovation of excellent reviews. Based on the successful experience of fujian unicom, China unicom group in 2009, print and communication computerrooms evaporative air conditioners energy management system requirements.
LiShiWang said, energy is the key to innovation and innovation of changing the world, only innovation is energy-saving. |
