摘要
针对间接利用地热水供暖系统中板式换热器温差设计及地热水能量的充分利用等问题,结合实际工程,从理论和实践两方面进行了分析。结果表明换热器传热温差的均匀性原则对小温差换热系统设计有指导作用;热泵技术是地热能梯级利用的有效措施之一。
In this paper, the design of temperature difference of panel heat-exchanger and energy utilizing of groundwater in the indirect groundwater heating system have been analyzed from both theoretics and practice according to actual project. The results indicate that the uniformity of temperature difference in panel heat-exchanger can be the directive effect in the design of heat exchange system with small temperature difference, and the heat pump technology is one of the effective measures in the rtmdle using of geothermal heat.
