公共建筑空调冷热源工程适用性的调查分析

Investigation-based Analysis on Applicability of Air Conditioning Cold and Heat Source of Public Buildings

对我国不同气候区6个城市的96栋公共建筑空调冷热源状况进行了调研。目前我国公共建筑的空调冷源主要以电为能源的蒸汽压缩式制冷冷水机组,以燃油和燃气为能源的溴化锂吸收式冷热水机组、各种类型的热泵机组也占有一定的比例,蓄冷技术和区域供冷技术应用不多。建筑类型决定了其使用功能,气候条件决定建筑的使用环境条件,均会影响空调冷热源的选择。根据调查,发现了目前冷热源存在的问题并对冷热源节能潜力进行了分析。

The cold and heat source of 96 public buildings in 6 cities in different climate zones were investigated. At present, in China, the chiller of vapor compression refrigeration is the major air conditioning cold source, the LiBr absorption chiller and heat pump units of various types also occupy a certain proportion. Storage technology and district cooling technology are seldom applied. Construction type de- termines the function of its use, climatic conditions determines the use environmental conditions of buildings, which will affect the choice of cold and heat sources. Based on the survey results, this article points out the problem and analyses the energy saving potential.
