压缩机和冷冻循环装置
摘要：
本发明提供能够确实地提高利用了气体制冷剂向压缩机构部的抽吸增压效果的情况下的压缩机性能的压缩机及冷冻循环装置。在具有压缩机构部、驱动该压缩机构部的电动机部和与压缩机构部的吸入口连通的吸入管，对R32制冷剂或包含70％以上重量百分比的R32制冷剂的混合制冷剂进行压缩的压缩机中，假设所述压缩机构部的排出容积以单位为m3计为V，所述吸入管的截面积以单位为m2计为A，所述吸入管的长度以单位为m计为L时，使关系式2≤L/(V/A)≤3成立。
摘要（英）：

The objective of the present invention is to provide a compressor and a refrigeration cycle device with which the performance of the compressor can be reliably improved when employing a supercharging effect to draws a gas refrigerant into a compressor mechanism portion. The compressor comprises the compressor mechanism portion, an electric motor portion which drives the compressor mechanism portion, and a suction pipe which is in communication with an intake port of the compressor mechanism portion. The compressor compresses R32 refrigerant or a mixed refrigerant containing at least 70% by weight of R32 refrigerant. The compressor is configured such that the relational expression 2 <= L/(V/A) <= 3 is satisfied, where V is the displacement volume of the compressor mechanism portion in units of m3, A is the cross-sectional area of the suction pipe in units of m2, and L is the length of the suction pipe in units of m.
