Embodiment Construction
[0038] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0039] Such as Figure 1 to Figure 12 As shown, Embodiment 1 of the present invention provides an expander, which includes a cylinder 60, a flange 10 and an adjustment assembly. The flange 10 is arranged on the cylinder 60, the flange 10 is provided with a first receiving groove 11 and a first suction groove 71, the first suction groove 71 is arranged on the first receiving groove 11, and the first suction groove 71 and the first suction groove 71 are arranged on the first receiving groove 11. The cylinder 60 is communicated so as to pass gas into the cylinder 60 through the first suction groove 71 . The adjustment assembly is arranged in the first accommodation tank 11, the adjustment assemb...

The present invention provides an expander and a refrigeration system thereof. The expander includes: a cylinder; a flange arranged on the cylinder; It is arranged on the first accommodation groove; the adjustment assembly is arranged in the first accommodation groove, the adjustment assembly has a flow channel, a first pressure channel and a second pressure channel, at least part of the flow channel is located between the first pressure channel and the second pressure channel Between, the outlet end of the flow channel is set opposite to the first suction groove; wherein, at least part of the adjustment assembly is rotatably set, the first pressure channel communicates with the expansion pressure chamber of the cylinder, and the second pressure channel communicates with the exhaust pressure of the cylinder. The cavities communicate with each other, so that at least part of the adjustment assembly can be rotated under the pressure difference between the first pressure channel and the second pressure channel, so as to change the inhalation amount of gas by changing the flow rate of the flow channel. To solve the technical problem of low efficiency of the expander in the prior art.
Description
technical field [0001] The invention relates to the technical field of expanders, in particular, to an expander and a refrigeration system having the same. Background technique [0002] At present, in the vapor compression refrigeration system, the throttling element is an important element to maintain the pressure difference between the condenser and the evaporator and control the flow of the system. The throttling elements commonly used in household and commercial refrigeration equipment are throttle valves and capillary tubes. . Whether it is a throttle valve or a capillary tube, its working principle is to use local resistance loss to rapidly reduce the pressure of the refrigerant. The throttling loss of carbon dioxide in the transcritical cycle accounts for 25%-30% of the total effective energy loss, and even the effective energy loss of traditional refrigerants during the throttling process accounts for 10%-20% of the total system loss. Throttle loss is an irreversib...
