在我国人们常认为回收低品位热量效益不大,这方面的技术无用武之地。本文介绍我们设计的回收和利用低品位热的设备和所获效益以及今后的发展方向。一、热泵用于地下建筑空调地下建筑都是冬暖夏凉,在辽宁地区一般的地下建筑冬季室温可达12℃,夏季只有5℃。所以,在冬季地下室内只要稍加热量便可维持适宜的温度;在夏季就得用锅炉或电加热器等
In China, people often think that the benefit of recycling low-grade heat is not significant, and the technology in this area is useless. This article describes the equipment we design for recycling and the use of low-grade heat, the benefits we receive, and the direction of future development. First, the heat pump for underground buildings Air conditioning underground buildings are warm in winter and cool in summer, in the general underground building in Liaoning area at room temperature up to 12 °C in summer, only 5 °C. Therefore, in the winter, the basement can maintain a suitable temperature as long as it is slightly heated; in the summer, it must use boilers or electric heaters, etc.
