Selecting reasonable scheme plays a vital role in reducing energy consumption and project cost.In this paper, tak- ing the project of Jianli public service center as an example, at first, the scheme of the equipment for cool and heat source is compared, the scheme of electric refrigeration and gas boiler is confirmed. And then the scheme is optimized on this ba- sis, through technical and economic analysis, the scheme of magnetic levitation frequency conversion centrifugal chiller and condensed vacuum hot water boiler is accepted finally to achieve economic running state and save energy. Key words ： magnetic levitation frequency conversion centrifugal chiller; condensed vacuum hot water boiler; energy conserva- tion and environment protection 參考文獻： 1 中華人民共和國國家發(fā)展和改革委員會國家信息中心 市場信息處 .2013年中國傳統(tǒng)中央空調(diào)升級改造分析報 告 EB/OL.2013-05-15.http:/intl.ce.cn/sjjj/qy/201305/15/ t20130515_24386281.shtml. 2 李春芳 .分布式能源整合優(yōu)化能源結(jié)構(gòu) 訪中國能源 網(wǎng) CIO 韓曉平 J.中國建設(shè)信息 .供熱制冷?？?,2004(3):26-29. 3 盛良薇 , 楊寶金 , 畢建強 , 等 .各類空調(diào)系統(tǒng)冷熱源初投資 及運行費用調(diào)研研究 J.中國設(shè)備工程 ,2018(5):39-40. 4 中華人民共和國國家發(fā)展和改革委員會 .國家重點節(jié)能 技術(shù)推廣目錄 (第五批 )J.造紙信息 ,2013(3):6. 5 殷平 .磁懸浮離心式冷水機組和國家標準 J. 暖通空調(diào) ,2013,43(9):53-61. （責任編輯 尚曉春 ） ANewPlantAerosolCultivationDevicebyUsingUltrasonicAtomization JIANG Zong-xiang ， LIN Le-bin， LI Jin-duo ， PENG Xiao-xu （ College of Mechanical and Electrical Engineering, Northeast Forestry University, Heilongjiang Harbin 150040 China ） Abstract ： In view of the problems of waste of nutrient solution and manpower in traditional soilless cultivation, the new type of aerosol cultivation device uses ultrasonic wave to atomize the culture medium, cooperates with temperature and humidity regulation to control plant growth, and innovatively solves the above problems. The device consists of an aerosol cultivation device and a temperature and humidity regulating system. The aerosol cultivation device is composed of a cultivation box, an atomizing device and a heating and ventilating device. The temperature and humidity regulating system is composed of a K60 microcontroller, a DHT11 digital temperature and humidity sensor and a LCD screen human-computer interaction interface, which can set the environmental threshold artificially.
