Energy consumption and application analysis of a new liquid dehumidification air conditioning system

传统空调系统通常采用温湿度联合处理的方式,该方式存在舒适性差、能源消耗大等问题。针对以上问题,提出一种利用复合直接蒸发冷却制冷水的溶液除湿空调系统,该系统可以有效节省功耗,符合节能减排的发展趋势。在研究过程中,以某办公楼为研究对象,利用TRNSYS仿真软件建立该系统,研究其在制冷季7—9月的能耗,分析其节能性及适用性。结果表明:当空调新风系统使用太阳能热水作为再生热源时,总供热能耗为6.1×10^(5)kW·h,总耗功为8.73×10^(4)kW·h。相比于传统空调系统,节能率达到55.2%,为降低空调系统能耗提供了新思路。

Traditional air conditioning systems usually use a combined temperature and humidity treatment method,which has problems such as poor comfort and high energy consumption.In response to the above problems,a solution dehumidification air conditioning system was proposed.It used compound direct evaporative cooling of chilled water,which can effectively save power consumption and is in line with the development trend of energy saving and emission reduction.In the research process,an office building was used as the research object,and the system was established using TRNSYS simulation software to study its energy consumption during the cooling season from July to September,and to analyse its energy saving and applicability.The results show that when the air-conditioning fresh air system uses solar hot water as a regenerative heat source,the total heating energy consumption is 6.1×10^(5) kW·h,and the total power consumption is 8.73×10^(4) kW·h.Compared with the traditional air-conditioning system,the energy saving rate reaches 55.2%,which provides a new idea for reducing the energy consumption of the airconditioning system.
