防护工程内信息化设备散热量大,余热会导致工程内部温度升高、设备失效甚至瘫痪.结合垂直埋管运行高效和水平埋管成本低廉的优势,采用复合埋管式地源热泵系统处理工程内余热以及口部潮湿问题,计算工程内通信机房和办公大厅的全年逐时负荷;利用 TRNSYS仿真软件构建复合埋管式与垂直埋管式热泵系统模型,比较复合埋管式热泵系统与传统的垂直埋管式热泵系统的热性能、经济效益及防潮效果.结果表明,在工程口部设定水平地埋管可有效降低口部空气相对湿度,起到防潮防湿的作用;在复合埋管式热泵系统总性能系数(coefficient of performance,COP)更高的前提下,复合埋管式热泵系统的总成本较垂直埋管式热泵系统降低了 21.8%.
Analysis on Performance of Composite Buried Pipe Heat Pump System in Protection Engineering
The large heat dissipation of information equipment in protective engineering will lead to the increase of internal temperature,equipment failure and even paralysis.Combined with the advantages of high efficiency of vertical buried pipe operation and low cost of horizontal buried pipe,a composite buried pipe ground source heat pump system is used to deal with the waste heat and moisture problems at the en-trance of the project.The annual hourly load of the communications rooms and office hall in the project is calculated;with the TRNSYS simulation software,a model of composite buried pipe and vertical buried pipe heat pump system is constructed to compare the thermal performance,economic benefits and mois-ture-proof effect of composite buried pipe heat pump system with those of the traditional vertical buried pipe heat pump system.The results show that the relative humidity of the air at the entrance can be re-duced effectively by setting the horizontal buried pipe at the entrance of the project,and horizontal buried pipes play the role of moisture-proof.Under the premise that the total coefficient of performance(COP)of the composite buried pipe heat pump system is higher,the total cost of the composite buried pipe heat pump system is reduced by 21.8%,compared with that of the vertical buried pipe heat pump system.
