摘要
基于目前公共建筑中传统集中空调存在的问题,提出了一种总线式空调系统。该系统由水环路和分散布置的水冷式热管复合空调机组、大焓差新风机组构成,根据内外区情况和室外气象条件可分别运行热管工况和空调工况,实现自然冷源、高温热源以及建筑自身余热的合理利用。以某一办公建筑为例,对该系统的全年运行能耗进行了模拟计算,并将模拟结果与风机盘管加新风系统和全空气系统进行对比。结果表明,该系统在经济性、节能性及室内热湿环境控制方面均具有明显优势,是一种有发展潜力的新型集中空调系统。
On account of the problems existed in the traditional central air conditioning systems of public buildings,puts forward a new central air conditioning system based on energy-bus.The system consists of distributed water-cooled air conditioning units combined with heat pipes,fresh air handing units with large enthalpy difference and a water loop.The new system can operate in either heat pipe mode or air conditioning mode according to peripheral and inner zones and climatic conditions so that it can make full use of natural cold source,high temperature heat source and excess heat in buildings rationally.The simulated annual energy consumption of the new system in an office building is compared with that of primary air fan-coil system and that of all-air CAV system.The result shows that the new system performs better in initial cost,energy saving and indoor thermal and humid environment control and may have great potential for further development and application.
