摘要
以某低温地热水供暖工程为例,分析了利用板式换热器与热泵机组联合供热的设计和运行情况,指出现有系统存在浪费地热能资源的缺点,提出了两种优化方案,分析比较了两种方案的能耗及性能指标,得出现有地热资源条件下较为合理的运行方式和地热尾水温度。
With a low-temperature geothermal water heating project,presents the design and operating conditions of the heating system combined plate exchanger with heat pump.Points out the problem that geothermal energy is seriously wasted in the existing system.Presents two optimal schemes,analyses and compares the energy consumption and performance indices between the two schemes,and puts forward rational control strategy and geothermal discharge water temperature.
