Experimental Study on the Performance Characteristic of a New-type Heat-source Tower with Pre-condensation Function

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 t...

Description
Summary: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.
