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。
Based on the existing problems of traditional centralized air conditioners in public buildings, a bus air conditioning system is proposed. The system consists of a water ring and a distributed water-cooled heat pipe composite air-conditioning unit and a large enthalpy difference fresh air unit. According to the situation inside and outside the area and outdoor weather conditions, the system can respectively run the heat pipe and the air-conditioning condition to realize the natural cold source and high temperature heat source As well as the rational use of building waste heat. Taking a certain office building as an example, the annual operation energy consumption of the system is simulated and the simulation results are compared with the fan coil plus fresh air system and the whole air system. The results show that the system has obvious advantages in terms of economy, energy saving and indoor heat and humidity control, and is a new type of centralized air conditioning system with potential for development.
