摘要
建立了该供热系统的热力学模型,推导出了供热负荷与设计参数、运行参数、环境温度的关系式。通过理论计算,分析了添加热泵与未加热泵两种工况下,散热器表面积、循环水流量、环境温度等对井下换热器性能及供热系统供热量的影响。
Establishes a thermodynamics model of the heating system, and deduces the relationship of heating load with design parameters, operation parameters and environment temperature. Based on theoretic calculation, analyses the influences of the heat radiator surface area, circulating water flow rate and environment temperature on the performance of the down-hole heat exchanger and the heat output of the heating system under the conditions with or without heat pump.
