Describing the rotary compressor 100 according to this utility model first aspect embodiment according to this utility model embodiment below with reference to Fig. 1-Fig. 4, the low-temperature heating excellent effect of this rotary compressor 100, performance are good, and simple in construction, applied widely.Wherein, rotary compressor 100 may be used in heat-exchange system.
As Figure 1-Figure 4, the rotary compressor 100 according to this utility model embodiment, including reservoir 1, housing 2, compression mechanism 3 and ejector 4.
Alternatively, rotary compressor 100 can be vertical compressor.Certainly, those skilled in the art are appreciated that rotary compressor 100 can also be horizontal compressor (not shown go out).It should be noted that, " vertical compressor " can be understood as the central axis upright of the compression mechanism 3 of rotary compressor 100 in the compressor of the installed surface of rotary compressor 100, such as, as Figure 1-Figure 4, the central axis compressing mechanism 3 vertically extends.Correspondingly, " horizontal compressor " can be understood as the centerline axis parallel of compression mechanism 3 in the compressor of the installed surface of rotary compressor 100.
Alternatively, rotary compressor 100 can be single cylinder compressor.Certainly, those skilled in the art are appreciated that rotary compressor 100 can also be multicylinder compressor (not shown go out).It should be noted that the compression mechanism 3 that " single cylinder compressor " refers to rotary compressor 100 is provided only with a cylinder, correspondingly, " multicylinder compressor " refers to compression mechanism 3 and is provided with two or more cylinders.In the application as explained below, illustrate for rotary compressor 100 for vertical, single cylinder compressor.
Specifically, reservoir 1 has refrigerant inlet 11 and refrigerant exit 12, and housing 2 is located at outside reservoir 1, and housing 2 is formed air vent 20, and compression mechanism 3 is located in housing 2, and compression mechanism 3 has air entry 30.
Ejector 4 and reservoir 1 are connected to air entry 30 place of compression mechanism 3 with being one another in series.In other words, ejector 4 and reservoir 1 all connect with the air entry 30 of compression mechanism 3 and ejector 4 and reservoir 1 are series relationship.Specifically, ejector 4 is located at refrigerant inlet 11 place of reservoir 1, and now air entry 30 directly connects with refrigerant exit 12；Or ejector 4 is located between the refrigerant exit 12 of reservoir 1 and the air entry 30 of compression mechanism 3, and now air entry 30 is by ejector 4 and refrigerant exit 12 indirect communication.Thus, the coolant being about to entrance reservoir 1 or the coolant flowed out from the refrigerant exit 12 of reservoir 1 can be carried out injection and increase enthalpy by ejector 4, to improve the pressure of the coolant entering compression mechanism 3, thus reducing the compression ratio of rotary compressor 100, improve the gas transmission ability of rotary compressor 100.
