The invention belongs to the technical field of refrigeration equipment, and particularly relates to a scroll compressor, refrigeration equipment and a vehicle. The scroll compressor comprises a machine shell internally provided with an oil separation structure and a throttling connection structure, a compression cavity, an oil return channel, a first oil storage cavity and a second oil storage cavity are further formed in the machine shell, the first oil storage cavity is communicated with an oil outlet of the oil separation structure, and the second oil storage cavity is communicated with the first oil storage cavity through the throttling connection structure. The second oil storage cavity is provided with an oil outlet end communicated with the oil return channel and an air storage end communicated with the compression cavity. Refrigeration oil separated by the oil separation structure enters the second oil storage cavity after being subjected to pressure reduction treatment through the first oil storage cavity and the throttling connection structure, the temperature and pressure of the refrigeration oil are reduced, refrigerants dissolved in the refrigeration oil are separated out and discharged to the compression cavity, and therefore when the refrigeration oil flows into the oil return channel from the second oil storage cavity, the refrigerants and heat carried by the refrigeration oil are reduced, and the refrigeration efficiency is improved. Therefore, reduction of volume efficiency and refrigerating capacity of the scroll compressor can be avoided, and guarantee is provided for efficient compression.

    本发明属于制冷设备技术领域,更具体地说,是涉及一种涡旋压缩机、制冷设备及车辆。涡旋压缩机包括内部设有油分结构和节流连接结构的机壳,机壳内还形成有压缩腔、回油通道、第一储油腔和第二储油腔,第一储油腔与油分结构的出油口连通,第二储油腔通过节流连接结构与第一储油腔连通,第二储油腔具有与回油通道连通的出油端和与压缩腔连通的储气端。经油分结构分离的冷冻油经第一储油腔和节流连接结构降压处理后进入第二储油腔,冷冻油的温度及压力降低,溶解于冷冻油内的冷媒析出并排出至压缩腔,如此,冷冻油从第二储油腔流入回油通道时,冷冻油携带的冷媒及热量减少,从而能避免涡旋压缩机容积效率及制冷量下降,并为高效压缩提供保障。
