摘要

R290作为一种环保型制冷剂，因易燃的特性导致其难以得到广泛应用，研究从产品开发的角度，针对R290分体式空调冷媒泄漏安全问题，通过搭建冷媒泄漏浓度分布监测实验平台，探究R290空调冷媒泄漏的分布规律；同时搭建了冷媒泄漏响应系统，用以确定传感器最优监测位置。实验结果表明：快速泄漏将会迅速在空调上方形成燃爆云团，通过启动风机和控制出风角度可以有效避免形成燃爆云团，但风量小于IEC标准对应最低风量的55%时，泄漏的冷媒无法被均匀扩散。通过实验还确定了最优监测点的选取条件，并制定了有效的防爆措施，能做到17s内快速响应，且期间无燃爆风险点出现。本研究为R290的应用和相关产品的开发提供了现实指导。

Abstract

R290 is an environmentally friendly Refrigerant

but it has flammable characteristics

making it difficult to be widely used. From the perspective of product development

aiming at the safety problem of refrigerant leakage of split-type air-conditioner using R290

the distribution law of refrigerant leakage was explored by building an experimental platform for detecting concentration distribution of refrigerant after leakage and a refrigerant leakage response system was built to determine the optimal detection location of the Sensor. The experimental results show that when the refrigerant leaks rapidly

the refrigerant will quickly form explosive clouds above the air conditioner. The explosive clouds can be effectively eliminated by starting the fan and controlling the Air outlet angle

but when the Air volume is less than 55% of the standard minimum Air volume

the leaked refrigerant cannot be evenly diffused. The selection conditions of the optimal detection position were determined by experiments

and effective explosion-proof measures were formulated

which can achieve rapid response within 17s

and there is no explosion risk area. This study provides guidance for the application of R290 and the development of products.
