摘要

为解决现有开式热源塔冬季运行时塔内溶液吸湿量大而影响系统运行安全的缺陷，故本文设计了一种具有预凝功能的新型热源塔结构，分析了新型塔的运行过程，并对比研究了新型塔和普通塔在不同进口溶液温度、空气流量和溶液流量下的运行性能。实验结果表明，新型塔具有更强的换热性能和更低的溶液吸湿性。进口溶液温度由1 ℃上升到3 ℃时，新型塔的换热量相比于普通塔增加了0.62~0.24 kW，溶液吸湿量平均减少了0.13 g/s；空气流量由1.41 kg/s升高到2.17 kg/s，新型塔的换热量相比于普通塔增加了0.79 ~0.84 kW，溶液再生量平均增加了0.1 g/s；溶液流量由0.36 kg/s升高到0.68 kg/s，新型塔的换热量相比于普通塔增加了0.57~0.63 kW，溶液吸湿量平均减少了0.11 g/s。

Abstract

The existing open heat-source tower has high moisture absorption rate in winter

which affects the safety of system. So a new-type heat-source tower structure with pre-condensation function was designed. The operation process of new-type tower was analyzed. The operation characteristic of new-type tower and ordinary tower were comparatively studied under different inlet solution temperature

mass flow of air and solution. The experiment results showed that the new-type tower had higher heat exchange performance and lower moisture absorption rate. Compared with ordinary tower

when inlet solution temperature rise from 1 ℃to 3 ℃

the new-type tower’s heat exchange rate increased 0.62 - 0.24 kW

and moisture absorption rate dropped 0.13 g/s in average; When air flow increased from 1.41 kg/s to 2.17 kg/s

the new-type tower’s heat exchange rate increased 0.79 - 0.84 kW

and moisture absorption rate dropped 0.1 g/s in average; When solution flow rate increased from 0.36 kg/s to 0.68 kg/s

the new-type tower’s heat exchange rate increased f 0.57 - 0.63 kW

and moisture absorption rate dropped 0.11 g/s in average.
