Absorption heat exchangers for long distance heat transportation.

Number: Keynote E2-Th-1

Author(s) : JIANG Y., XIE X.

Summary

A novel system for long distance heat transportation using two types of absorption heat exchangers (AHEs) is prompted in this paper. Using the system, the industry waste heat at 65~70°C can be recovered and transported through a long distance pipeline. The transported temperature difference can be increased two times more than normal system based on conventional heat exchangers for heat transfer. Considering the reduction of the pipe network cost balance with the added AHEs cost, an economic balance distance is obtained, and when the distance is longer than the economic balance distance, the AHEs system can save the initial cost. The economic balance distance is in direct proportion to the transportation pipe diameter. Take the pipe with diameter 1020mm for example, the economic balance distance is about 28km. While when considering the transportation electricity consumption reduction of the novel system, the economic balance distance can be shortened The 1sttype AHEs has been developed for several years. The small sized AHE is introduced intensively, including the structure, the testing performance and the application projects, which constructs the building type heat supply system with a very wide application prospect.
