| 摘 要： | 设计研究出一种采用自动变频调速容量调节的热泵系统,对其工作机理进行分析,并进行了模拟实验。实验结果表明:热泵系统按质调节方式运行,采用自动调频变速实现容量调节是可行的。当采暖对象温度改变时,热泵压缩机的转速和热量输出在负反馈调节环路的作用下也相应变化,从而保持采暧对象的温度基本稳定。

| Abstract: | This paper presents a heat pump capacity control system and its opreating principle. The speed of the compressor can be regulated by an automatic frequency converter. The results of simulating experiments with this system show that it is possible to control the heat pump capacity automatically by regulating the frequency of the converter under quality-regulation. When the temperature of a heated object changes in the modulating experiment, the speed of the compressor and the heating output change correspondingly under the action of negative feedback and hence the temperature of the object keeps constant. |
