摘 要: 本文针对低温地热采暖方式的特点,应用技术经济学原理,分析了采暖系统最佳运行参数组合关系及其影响因素,对低温地热采暖系统中采用风机盘管运行参数进行了整体优化,最终得到不同设计负荷下地热利用温降和最佳运行工况。通过分析和优化设计,在低温地热采暖系统中采用风机盘管较其他常规采暖方式能够有效地降低运行成本,进一步深化资源的开发利用,提高经济性。 This paper describes the optimization performance of a low-temperature geothermal heating system by using a fan-coil unit. In accordance with the characteristics of the system, the optimization operational parameters and affecting factors are discussed and defined in detail by computations and principle of engineering economics. The results indicate that the fan-coil unit can be utilized a low-temperature geothermal heating system (blow 45°C of inlet temperature), and is more effectively and economically than using conventional equipments, such as radiators.
