| 3 | Development of Submersible Corrugated Pipe Sewage Heat Exchanger显示文摘Based on the characteristics of heat transfer for corrugated pipe,a method of calculating and design on the submersible corrugated pipe sewage heat exchanger was put forward theoretically and experimentally.The actual movement parameters of air-conditioning system used in this heat exchanger were measured.The experimental result shows that the quantity of heat transfer of the corrugated pipe sewage heat exchanger can satisfy the building's load with the average coefficient of performance 4.55.At the same time,the quantity of heat transfer of the corrugated pipe sewage heat exchanger was compared with that of the other nonmetallic sewage heat exchangers(i.e.,the plastic-Al pipe sewage heat exchanger and PP-R pipe sewage heat exchanger)experimentally.It is found out that the effect of heat transfer for submersible corrugated pipe sewage heat exchanger is superior to those of the plastic-Al pipe and the PP-R pipe.The quantity of heat transfer per mile of corrugated pipe sewage heat exchanger is 5.2 times as much as that of the plastic-Al pipe,and it is 8.1 times as much as that of PP-R pipe. | BAI Li1,2,SHI Yan1,TAN Yu-fei2(1.Institute of Municipal and Environmental Engineering,Jilin Institute of Architecture and Civil Engineering,Changchun,Jilin 130021,China 2.Institute of Municipal and Environmental Engineering,Harbin Institute of Technology,Harbin,Heilongjiang 150090,China) | 2009 | 湖南大学学报(自然科学版)2009，36，S1： | 0 |
