Problems solved by technology

However, these schemes failed to integrate the processes of throttling, drainage, gas-liquid separation, and heat recovery into the same device, resulting in low operational reliability and compact structure of the system. At the same time, due to the different shapes, the processing and manufacturing costs of components high; as figure 1 As shown, the ejector 30' and the gas-liquid separator 32' of the existing ejector refrigeration cycle are separate system components, and the structure is not compact, which increases the complexity of the system operation, and the cost of processing and manufacturing components is too high and the practicability is low. ; or if figure 2 and image 3 As shown, there is also an injector 30' and a separator 32' integrated together, but the injector 30' is fixed on the side wall of the separator 32', the structure is complicated, and the processing is difficult

Embodiment 1

[0056] Such as Figure 4 As shown, the throttling component 3 according to an embodiment of the present invention includes: a fixedly connected injector 30 and a separator 32. The main body of the injector 30 has a throttling part 300, a diversion part 304 and a mixed flow The tee pipe of part 302, the end entrance of the throttling part 300 on the tee pipe is fixedly connected with a positioning end cap 306, and the positioning end cap 306 is covered on the end of the throttling part 300, and the positioning end cap 306 is A throttling tube 308 runs through, and the throttling tube 308 extends into the throttling part 300 through the positioning end cap 306; a mixing tube 303 is coaxially fixed in the mixing part 302, one end of the mixing tube 303 is fixedly connected with the mixing part 302, and the other end Stretch in the separator 32 from the end of the separator 32, the ejector 30 is fixedly connected with the end of the separator 32 by the flow mixing pipe 303; The m...

Embodiment 2

[0076] The throttling component 3 according to an embodiment of the present invention is modified on the basis of the first embodiment. The difference from Embodiment 1 is that the throttling tube 308 is replaced with an orifice.

[0077] Specifically, the positioning end cap 306 of this embodiment is provided with a throttling hole, and the throttle tube 308 is replaced by the throttling hole, thereby saving parts, reducing parts, simplifying the structure, simplifying the processing technology and installation process , improve work efficiency and reduce costs. Considering the length of the throttling tube 308, the orifice can be lengthened by thickening the positioning end cap 306, or the position of the orifice can be thickened separately so that the surface of the positioning end cap 306 is convex at the position of the orifice , thereby increasing the length of the orifice.

[0078] Another difference between this embodiment and Embodiment 1 is that the flow mixing pip...

Embodiment 3

[0082] Such as Figure 5 As shown, the refrigeration cycle system of an embodiment proposed by the present invention adopts the throttling component 3 of any of the above-mentioned embodiments, including: a compressor 1, a condenser 2, a throttling component 3, an evaporator 4, and a regenerator 5 , The throttling part 3 is placed between the circulating regenerator 5 and the evaporator 4, and the refrigerant realizes multiple processes such as throttling, drainage pressurization, and gas-liquid separation in the throttling part 3 .

[0083] By adopting the throttling component 3 of any one of the above-mentioned embodiments, all the beneficial effects of the above-mentioned embodiments are obtained, and details are not repeated here.

[0084] The technical solution of the present invention has been described in detail above in conjunction with the accompanying drawings. Through the technical solution of the present invention, multiple functions such as throttling, drainage an...

Abstract

The invention provides a throttling component comprising an ejector and a separator. The ejector is provided with a flow mixing pipe, and the ejector is fixedly connected with the end of the separatorthrough the flow mixing pipe. By means of the technical scheme, multiple functions such as throttling, drainage pressurization and gas-liquid separation are effectively concentrated on one component,the structure compactness is improved, the space is saved, the overall strength is improved, installation is quicker and more convenient, and the fluid pressure at an evaporator outlet is increased,so that the compressor pressure ratio is reduced, and the overall energy efficiency of a refrigeration system is improved; and the throttling component is made of a pipe member, and the cost is also greatly reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a throttling component and a refrigeration cycle system. Background technique [0002] Conventional vapor compression refrigeration systems include major devices and components such as compressors, condensers, throttling elements, evaporators, and gas-liquid separators. With the increasingly tense energy forms, the energy efficiency requirements for vapor compression refrigeration cycles are also getting higher and higher. At present, the mainstream solutions for improving energy efficiency focus on reducing the power consumption of the compressor and improving the heat exchange efficiency of the condenser / evaporator. [0003] Throttle is the process of converting the refrigeration potential of the refrigerant into the actual refrigeration capacity in the refrigeration cycle. On the one hand, it realizes the transformation of the refrigerant from a high-temperature state t...
