置换通风对地板供冷系统结露影响的初步分析

Preliminary analysis on effects of displacement ventilation to condensation in cooling floor system

地板供冷与置换通风相结合在国内外的工程中常采用。置换通风不但可以提供满足房间卫生要求的新风,还可以防止地板供冷系统地面结露。本文通过对置换通风与地板供冷结合的理论与实验分析,认为置换通风系统不能解决地板的结露问题,但在一定程度上可以缓解结露的严重程度。对置换通风的新风进行干燥处理,其处理状态与室内外的湿环境状态相关,对其进行实时监控和调节才能做到防止地面结露。

The combination of floor cooling and displacement ventilation is a common method, which was used in the engineering application. Displacement ventilation not only offers fresh air for room＇ s sanitary requirement, but also prevents the floor surface from condensation. This paper analyzed the floor cooling and displacement ventilation in the experiment and the theory, which indicates that the displacement venti- lation can not solve the condensation problem but reduce the condensation in some degree. It comes to the conclusion that the condition point of the dry fresh air in displacement ventilation is relation to the indoor and outdoor humidity environment, and real - time monitoring can prevent the surface from condensation.
