【摘要】：随着生活的改善,人均居住面积的提高,人们对于能够覆盖较大空间的制冷能力的要求也在不断提高。传统的家用空调己无法满足需求,原来仅用于商用空调的涡旋压缩机开始逐渐进入家用空调领域。作为其中的动力源,能够对应民用电源的只有单相电动机。涡旋压缩机使用的单相电动机普遍存在能效低、起动性差、成本高等弊端。同时,国家针对日益严重的环境污染问题,也在不断出台相关政策法规以达到节能减排的目标。 空调及热泵常用的制冷压缩机中以高效、低噪著称的涡旋压缩机最为节能。为了更好的满足市场需求并进一步推广节能减排的理念,就需要对单相电动机进行整体性能优化研究。目前为止对于将单相电动机搭载在涡旋压缩机的应用设计研究不多,本文对以下几个方面进行系统研究。 针对单相电动机应用到涡旋压缩机上出现了能效较低,起动效果差,材料成本高的问题。采用将单相电动机的结构和磁路的特点与压缩机应用相结合的研究方法,通过减小转子外径,增大定子轭部宽度减小定子轭部磁密,增加制冷剂流通面积。提高了单相电动机的效率与起动性能。 编写了电磁设计的程序,计算了样机的电磁参数,并使用MagNet仿真软件,建立了电动机仿真模型,进行了求解分析。结果表明所设计的样机在效率上有所提高,电动机的起动转矩增大,起动电流减小,起动时间缩短,综合性能有显著提高。 同时,进行了样机的试制加工,通过电动机试验与压缩机的应用试验验证了电动机的性能。结果表明：按照上述思路和方法进行电动机的设计并结合有效地生产工艺,可提高电动机能效、改善压缩机起动性和降低电动机的材料成本。本研究为单相电动机在涡旋压缩机的应用研究及推广方面提供了技术参考。
[Abstract]:With the improvement of life and the increase of living area per capita, the requirement of refrigeration ability to cover large space is also increasing. Traditional domestic air conditioning has been unable to meet the demand. The scroll compressor, which is used only for commercial air conditioning, has gradually entered the field of household air conditioning. As the power source, only single-phase motor can correspond to civil power supply. Single-phase motors used in scroll compressors have many disadvantages, such as low energy efficiency, poor starting performance and high cost. At the same time, in view of the increasingly serious problem of environmental pollution, the state has been issuing policies and regulations to achieve the goal of energy saving and emission reduction. Air-conditioning and heat pump commonly used refrigeration compressor with high-efficiency, low-noise scroll compressor is the most energy-saving. In order to better meet the market demand and further promote the idea of energy saving and emission reduction, it is necessary to optimize the overall performance of single-phase motor. Up to now, there are few researches on the application of single-phase motor in scroll compressor. In view of the problems of low energy efficiency, poor starting effect and high material cost of single-phase motor applied to scroll compressor. By combining the structure and magnetic circuit of single-phase motor with the application of compressor, the width of stator yoke is increased and the magnetic density of stator yoke is reduced by reducing the outer diameter of rotor, and the circulating area of refrigerant is increased. The efficiency and starting performance of single phase motor are improved. The electromagnetic design program is written, the electromagnetic parameters of the prototype are calculated, and the simulation model of the motor is established by using the MagNet simulation software, and the solution is analyzed. The results show that the efficiency of the designed prototype is improved, the starting torque of the motor is increased, the starting current is decreased, the starting time is shortened, and the comprehensive performance is improved significantly. At the same time, the prototype is manufactured and the performance of the motor is verified by the motor test and the application test of the compressor. The results show that according to the above ideas and methods, the motor design and effective production technology can improve the motor energy efficiency, improve the starting performance of compressor and reduce the material cost of the motor. This study provides a technical reference for the application and popularization of single-phase motor in scroll compressor.
