关于多联式空调室内机结霜问题的试验与分析

Experiment and analysis on frosting problem of multi-connected air conditioner indoor unit

针对当环境温度较低时,室内机普遍易结冻的问题,本文通过理论分析,并结合实际测试情况,对室内机可能结冻的情况进行了分析,得出解决室内机结冻问题的方法,需要考虑提高系统运行的蒸发压力,又需保证压缩机运行的可靠性,防止气液分离器积液过多。

For the problem that when the ambient temperature is low,the internal machine is generally easy to freeze.Through theoretical analysis and combined with the actual test situation,this paper analyzes the possible freezing of the internal machine.And proposes a solution to the problem of freezing of indoor units,It is necessary to consider increasing the evaporation pressure of the system operation,and also to ensure the reliability of the compressor operation and prevent excessive liquid accumulation in the gas-liquid separator.
