风管送风式空调(热泵)机组室内机防凝露设计

Anti-condensation design of indoor unit of ducted air-conditioning(heat pump) units

针对风管送风式空调(热泵)机组室内机非出风口处外观面凝露现象,建立仿真模型并计算得到流场仿真云图,通过分析云图中气流通过低温源以及流经区域的流速,找到凝露区域,确定凝露传递路径,制定防凝露整改措施,将原凝露区域风速降至1 m/s以下,防凝露设计方案的可靠性得到提升。

Aiming at condensation phenomenon of appearance surface at non-outlet of indoor unit of ducted air-conditioning(heat pump)units,the simulation model is established and the simulation cloud chart of the flow field is calculated.By analyzing the velo-city of airflow through the low temperature source and through the region in the cloud chart,the condensation area is found,the condensation transmission path is determined;the anti-condensation rectification measures are made,and the flow rate in the condensation region is reduced below 1 m/s,which improves the reliability of the anti-condensation design.
