一种氟泵双循环空调室内机组静音降噪结构

Abstract

本实用新型提供一种氟泵双循环空调室内机组静音降噪结构，涉及氟泵双循环空调室内机组降噪领域，包括室内机组件，包括室内机本体、位于室内机本体出风口的消音静压箱、与消音静压箱连通的风管、用于出风的排风口、位于风管和排风口之间的消音管；本实用新型通过设置消音静压箱与消音管，对气流在出风口与风管之间的流动进行缓冲与降噪处理，有效减少了因空气流动引起的涡流噪声,通过悬挂组件中的橡胶垫与螺母配合，不仅能实现对室内机组的稳固悬挂，还能通过橡胶材料的缓冲特性，吸收机组运行时产生的振动噪音,支撑组件中采用橡胶圈包裹风管，上下卡箍通过紧固螺栓固定，形成了对风管的柔性支撑，防止风管在运行过程中因振动产生噪音。
