【摘要】：隨著生活的改善,人均居住面積的提高,人們對(duì)于能夠覆蓋較大空間的制冷能力的要求也在不斷提高。傳統(tǒng)的家用空調(diào)己無(wú)法滿足需求,原來(lái)僅用于商用空調(diào)的渦旋壓縮機(jī)開始逐漸進(jìn)入家用空調(diào)領(lǐng)域。作為其中的動(dòng)力源,能夠?qū)?yīng)民用電源的只有單相電動(dòng)機(jī)。渦旋壓縮機(jī)使用的單相電動(dòng)機(jī)普遍存在能效低、起動(dòng)性差、成本高等弊端。同時(shí),國(guó)家針對(duì)日益嚴(yán)重的環(huán)境污染問題,也在不斷出臺(tái)相關(guān)政策法規(guī)以達(dá)到節(jié)能減排的目標(biāo)。 空調(diào)及熱泵常用的制冷壓縮機(jī)中以高效、低噪著稱的渦旋壓縮機(jī)最為節(jié)能。為了更好的滿足市場(chǎng)需求并進(jìn)一步推廣節(jié)能減排的理念,就需要對(duì)單相電動(dòng)機(jī)進(jìn)行整體性能優(yōu)化研究。目前為止對(duì)于將單相電動(dòng)機(jī)搭載在渦旋壓縮機(jī)的應(yīng)用設(shè)計(jì)研究不多,本文對(duì)以下幾個(gè)方面進(jìn)行系統(tǒng)研究。 針對(duì)單相電動(dòng)機(jī)應(yīng)用到渦旋壓縮機(jī)上出現(xiàn)了能效較低,起動(dòng)效果差,材料成本高的問題。采用將單相電動(dòng)機(jī)的結(jié)構(gòu)和磁路的特點(diǎn)與壓縮機(jī)應(yīng)用相結(jié)合的研究方法,通過(guò)減小轉(zhuǎn)子外徑,增大定子軛部寬度減小定子軛部磁密,增加制冷劑流通面積。提高了單相電動(dòng)機(jī)的效率與起動(dòng)性能。 編寫了電磁設(shè)計(jì)的程序,計(jì)算了樣機(jī)的電磁參數(shù),并使用MagNet仿真軟件,建立了電動(dòng)機(jī)仿真模型,進(jìn)行了求解分析。結(jié)果表明所設(shè)計(jì)的樣機(jī)在效率上有所提高,電動(dòng)機(jī)的起動(dòng)轉(zhuǎn)矩增大,起動(dòng)電流減小,起動(dòng)時(shí)間縮短,綜合性能有顯著提高。 同時(shí),進(jìn)行了樣機(jī)的試制加工,通過(guò)電動(dòng)機(jī)試驗(yàn)與壓縮機(jī)的應(yīng)用試驗(yàn)驗(yàn)證了電動(dòng)機(jī)的性能。結(jié)果表明：按照上述思路和方法進(jìn)行電動(dòng)機(jī)的設(shè)計(jì)并結(jié)合有效地生產(chǎn)工藝,可提高電動(dòng)機(jī)能效、改善壓縮機(jī)起動(dòng)性和降低電動(dòng)機(jī)的材料成本。本研究為單相電動(dòng)機(jī)在渦旋壓縮機(jī)的應(yīng)用研究及推廣方面提供了技術(shù)參考。
[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.
