Embodiment Construction

[0010] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] like figure 1 As shown, the present invention includes an electronic expansion valve 5 and a capillary assembly branch to be tested. The capillary assembly branch to be tested is composed of a capillary assembly 4 and a stop valve 2 connected in series at both ends thereof. parallel connection; the two ends of the parallel flow path are respectively connected in series with connectors 1 that are screwed to the refrigerant pipeline; in order to facilitate the replacement of different capillaries in the capillary matching test, between the two ends of the capillary assembly 4 and the stop valves 2 at both ends There are screw-type connectors 3 connected in series respectively. All the above-mentioned components are connected by connecting pipes with inner hollows.

[0012] When the present invention is used, as figure 2 As shown, th...

Abstract

The invention relates to a fast matching device of the length of a capillary for an air-conditioner, comprising an electronic expansion valve and a capillary component branch to be tested; the capillary component branch to be tested consists of a capillary component and stop valves which are respectively connected with the two ends thereof in series, and the capillary component branch to be tested is connected with the electronic expansion valve in parallel. The fast matching device can not only fast determine the capability of throttling and reducing pressure of the capillaries with the different lengths with the help of the electronic expansion valve, but can also carry out the on-line fast replacement of the capillary component with the help of the stop valves which are arranged at the two ends of the capillary component, thereby greatly improving the efficiency and the accuracy of the matching of the length of the capillary.

Description

technical field [0001] The invention relates to the field of air conditioner manufacturing, in particular to a quick matching device for the length of a capillary used in an air conditioner, which can quickly and accurately determine the throttling and pressure-reducing capacity of the capillary. Background technique [0002] In the field of air conditioning, especially in the field of central air conditioning, due to the limitations of the fan duct of the air conditioner, for the heat exchanger, the amount of air received by different parts and different flow paths is different, resulting in different heat transfer effects of different flow paths, affecting To improve the capacity and energy efficiency of the air conditioner, it is necessary to accurately determine the length of the capillary of each flow path through adjustment to ensure that the subcooling and superheating degrees of each flow path are consistent. At present, the commonly used debugging method for capilla...
