【摘要】：氣液分離器作為保障制冷系統(tǒng)安全運(yùn)行的重要部件,廣泛應(yīng)用于制冷系統(tǒng)中。由于運(yùn)行工況的不同,氣液分離器尺寸結(jié)構(gòu)的差異,其對(duì)制冷系統(tǒng)的整體運(yùn)行將產(chǎn)生不同的影響。因此,對(duì)氣液分離器進(jìn)行優(yōu)化設(shè)計(jì)有著重要的實(shí)際應(yīng)用價(jià)值。本文以某型號(hào)的冷水機(jī)組的氣液分離器為研究對(duì)象,對(duì)其結(jié)構(gòu)、流動(dòng)和噪聲等展開了相應(yīng)的分析和研究。(1)通過相關(guān)文獻(xiàn)和額定工況運(yùn)行參數(shù)以及制冷劑充注量,確定了氣液分離器的容積、直徑及高度等參數(shù)數(shù)值。(2)在額定運(yùn)行工況下,分別采用數(shù)值法和解析法,對(duì)氣液分離器進(jìn)行了結(jié)構(gòu)應(yīng)力分析,得到封頭受力情況,結(jié)果顯示數(shù)值法更適合于額定工況下氣液分離器的受力計(jì)算。(3)對(duì)氣液分離器內(nèi)制冷劑的流動(dòng)進(jìn)行數(shù)值模擬,得到氣液分離器內(nèi)部壓力分布、速度分布及頻率聲壓關(guān)系曲線。結(jié)果顯示回油孔設(shè)置具有一定的合理性;氣動(dòng)噪聲產(chǎn)生的位置主要位于氣液分離器的底部。(4)應(yīng)用有限元方法對(duì)氣液分離器的殼體進(jìn)行了模態(tài)分析,得到了分離器的固有頻率。對(duì)氣液分離器在壓縮機(jī)工作情況下進(jìn)行了動(dòng)態(tài)響應(yīng)模擬,得到了動(dòng)態(tài)響應(yīng)曲線。(5)采用正交試驗(yàn)設(shè)計(jì)方法,對(duì)氣液分離器內(nèi)腔外套管長度、套管管徑比及回油孔孔徑對(duì)壓降的影響進(jìn)行了研究。結(jié)果顯示,外套管高度為450mm,管徑比2.73時(shí),對(duì)壓降的影響最大。
[Abstract]:As an important component to ensure the safe operation of refrigeration system, gas-liquid separator is widely used in refrigeration system. Because of the different operating conditions and the difference of the size and structure of the gas-liquid separator, it will have different influence on the whole operation of the refrigeration system. Therefore, the optimization design of gas-liquid separator has important practical application value. In this paper, the structure, flow and noise of the gas-liquid separator of a certain type of chillers are analyzed and studied. (1) through the relevant literature, operating parameters under rated operating conditions and refrigerant charge, The volume, diameter and height of the gas-liquid separator are determined. (2) under rated operating conditions, the structural stress of the gas-liquid separator is analyzed by numerical method and analytical method, and the stress of the head is obtained. The results show that the numerical method is more suitable for the force calculation of the gas-liquid separator under rated working conditions. (3) numerical simulation of the refrigerant flow in the gas-liquid separator is carried out, and the pressure distribution, velocity distribution and the relationship between frequency and sound pressure in the gas-liquid separator are obtained. The results show that the setting of the return hole is reasonable and the position of the pneumatic noise is mainly at the bottom of the gas-liquid separator. (4) the modal analysis of the shell of the gas-liquid separator is carried out by using the finite element method, and the natural frequency of the separator is obtained. The dynamic response of the gas-liquid separator is simulated under the condition of compressor operation, and the dynamic response curve is obtained. (5) the length of the casing tube in the inner cavity of the gas-liquid separator is calculated by the orthogonal design method. The influence of casing diameter ratio and oil return hole diameter on pressure drop is studied. The results show that the pressure drop is most affected when the tube height is 450 mm and the diameter ratio is 2.73.
