[0004] However, the existing capillary device disclosed in the above patent application for refrigeration matching and debugging of air conditioning systems will have some refrigerant accumulated in some non-working capillary tubes and collectors when it is used for refrigeration matching and debugging, and will not participate in the heat exchange cycle of the refrigerant. This will reduce the accuracy of the refrigeration parameters, so the capillary specifications and the set refrigerant quantity cannot achieve the optimal combination in mass-produced air-conditioning systems

Embodiment Construction
[0036] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] The present invention provides a capillary device for refrigeration matching debugging of air conditioning system, please refer to figure 1 , which discloses a preferred embodiment of the capillary device for refrigeration matching and debugging of an air conditioning system according to the present invention. End adjustment device 200.
[0038] see Figure 2 to Figure 6 , the regulating device 200 has an upper cover 210 , a regulating valve 220 and a bottom case 230 . The upper cover 210 has a disc-shaped cover plate 211 and an upper cover side plate 212 perpendicularly bent and extended from a side edge of the cover plate 211 . A pivot shaft 213 extends vertically from the middle of the cover plate 211 and extends in the same direction as the upper cover side plate 212 . An end of the pivot shaft 213 adjac...

The invention discloses a capillary tube device used for refrigeration matching debugging of an air-conditioning system, which comprises two regulating devices and at least two capillary tubes. Each adjusting device has an upper cover, a bottom case and a regulating valve. The two ends of the regulating valve are respectively connected to the upper cover and the bottom case. The shell is provided with a plurality of bottom shell through holes at the sealing connection between the regulating valve and the regulating valve. One of the vias is connected. Each capillary communicates with a corresponding bottom case through hole of the bottom case of the corresponding adjusting device. Since the capillary device used in the refrigeration matching debugging of the air-conditioning system of the present invention moves the regulating valve so that the passage of the regulating valve communicates with a through hole of the bottom shell, thereby selecting one of the multiple capillary pipes to transport the refrigerant, so in the refrigeration matching of the air-conditioning system Improved accuracy of refrigeration parameters during commissioning.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a capillary device used for refrigeration matching and debugging of an air conditioning system. Background technique [0002] During the development process of the air conditioning system, refrigeration matching and debugging are required. Refrigeration matching and debugging is mainly to determine the amount of refrigerant and capillary tube specifications for the later mass-produced air-conditioning system, so the capillary device is needed in the refrigeration matching and debugging process of the air-conditioning system. [0003] Chinese patent applications with application numbers 201120288730.8, 201020102933.9, and 200820133808.7 disclose existing capillary devices for refrigeration matching and debugging of air-conditioning systems, which are basically composed of capillary tubes, gas collecting pipes, and multiple stop valves. [0004] However, the existing capi...
