New Solar Energy Air Conditioner System Had Been Settled In Tianjin
The solar eneregy air conditioner system of Tianjin software centre was installed and implied by YuanDa air conditioner Company,the investment of the project is more than 10,000,000RMB,it have a pair of energy of 主机solar energy and natural gas,when such solar energy as rainy day and night,etc. are insufficient,the 主机operated to cool or heat by the directed firing machine circulation. According to a schedule,Tianjin will also have air conditioners of nearly 40 sets of solar energy to be installed and come into operation successively within the year.
At present,the technology of domestic and international solar energy utilization concentrates on the following several respect mainly: Gather lighting technology in direct sunlight; Solar energy photovoltaic generating technology; The solar energy and heat utilizing technology. The solar energy utilizing technology,is mainly pointed to the solar water heater,solar energy air conditioner,etc.
Our country is one of countrys with abundant solar energy resource,the annual sunshine time of the more than 2/3 area of whole country,greater than 2000 hours,the sun radiation energy that the area of land accepts every year is equivalent to 2.4* 10,400 million tons of standard coal,nearly mean the total of generation of several tens of thousands of the Three Gorges Projects. If to utlizing the solar energy effectivly,it will have great and far-reaching meaning for alleviate of our country energy nervous,reducing air pollution,protecting ecological environmenting,bring about an advance in economy.
天津华苑软件园太阳能空调系统由远大空调公司安装实施，项目投资1千多万元，使用太阳能、天然气双能源主机，在下雨天和夜晚等太阳能不足时，主机以直燃机循环进行制冷或制热运行。按照计划，年内天津市还将有近40台太阳能空调陆续安装并投入使用。
目前，国内外太阳能利用技术主要集中在以下几个方面：直接的太阳光采集照明技术；太阳能光伏发电技术；太阳能热利用技术。太阳能利用技术，主要指太阳能热水器、太阳能空调等。
我国属太阳能资源丰富的国家之一，全国总面积2/3以上地区年日照时数大于2000小时，陆地面积每年接受的太阳辐射能相当于2.4×104亿吨标准煤，约等于数万个三峡工程发电量的总和。如果将这些太阳能有效利用，对于缓解我国能源紧张、减少大气污染、保护生态环境、促进经济发展具有重大而深远的意义。
