摘要
本文从利用生活污水管道中的热空气将空气源热泵转换为高效率的污水源热泵出发,对排水管道中水气热量交换过程进行分析,推导出以焓差为推动力的水气换热公式,并通过现场测试,提出初步的修正系数.以期为将排水管道作为换热设备的工程实施提供依据。
Aimed making use of hot-air in wastewater pipe to brush up the efficiency of air-source heat pump,the progress of the heat exchange between wastewater and air is has been analyzed,and the enthalpy difference formula and the amendment modulus having reference value by test is provided.An engineering design theory formula for using the pipeline as heat transfer equipment will be gained in this paper.
