摘要
详细介绍了制冷系统稳定性问题发现以来的研究进展,并对其成果进行了分析。根据研究对象不同将前人对制冷系统稳定性研究分为蒸发器完全蒸干点随机震荡现象研究、蒸发器和热力膨胀阀控制回路稳定性研究、定容量制冷系统稳定性研究和无级变容量制冷系统稳定性研究四大类。指出整个研究遵循由局部到整体、由简单到复杂的主线。对无级变容量制冷系统的稳定性进行试验研究,理论上借鉴定容量制冷系统的成果,研究无级变容量制冷系统稳定性机理和有效控制新方法是近期的研究方向。
Stability investigation of refrigeration systems from historical review was introduced and the achievements were analyzed. According to different research objective ,study on stability of refrigeration system is divided into four phase: study on random vibration of the fully dried out point of evaporators, study on stability of control loop of evaporator and thermo expansion valves, study on stability of constant -capacity refrigerating system and study on stability of variable-displacement refrigeration system . the whole research keep the masterstroke from part to integer and from simpleness to complexity. Considering the research situation of stability investigation of variable-displacement refrigeration systems, puts forward that the research direction of future is to study the mechanism and efficient control methods using the fruits of constant-capacity refrigeration system for reference .
