Throttle valve adjusting device, debugging system and debugging method

Abstract

The invention provides a throttle valve adjusting device, a debugging system and a debugging method. The throttle valve adjusting device comprises a valve seat and a seal connector, wherein a containing cavity used for containing a valve element is arranged in the valve seat, the seal connector is detachably connected with the valve seat in a sealed manner, and the valve element is replaced through disassembly of the seal connector. Due to the arranged valve seat, the containing cavity and the seal connector, the valve element is detachably sealed in the containing cavity in a replaceable manner, and replacement operation of the valve element is easy, rapid and convenient; and in this way, the operation efficiency of replacement is improved beneficially, and the debugging efficiency is improved beneficially. Besides, a throttle valve is arranged to be used as a valve element, throttle valves of different specifications can be used as the valve element to be installed in the containing cavity, and it is achieved that the throttle valves of different specifications can be replaced in the debugging process. By the adoption of the throttle valve adjusting device, it is achieved that the throttle valve is used for debugging in the air conditioner performance debugging process, the throttle valves are used for throttling in the batch production process beneficially, and the matching performance of batch production is improved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning experiment tooling, and in particular relates to a throttle valve adjusting device, a debugging system with the throttle valve adjusting device, and a debugging method of the debugging system. Background technique [0002] In the refrigeration industry, especially in the air-conditioning industry, a new product has to go through several stages when it comes to the market, among which the performance of the initial prototype is an important stage. Refrigeration and heating, as the basic functions of air conditioners, are one of the key assessment indicators in the performance matching stage. In order to achieve the specified cooling and heating capacity and energy efficiency target values, the performance matching debugging stage often needs to control the flow rate of the refrigerant in the refrigeration cycle system of the product. Adjust in order to achieve the best capacity and energy ...

AI Technical Summary

Problems solved by technology

[0003] In the process of air conditioner development performance matching and debugging in the air conditioning industry, it is often necessary to use an external throttling device to adjust the refrigerant flow of the system. At present, air conditioner manufacturers often use capillary tubes or electronic expansion valves for performance matching in the product development process. Capillary tubes mainly The refrigerant flow rate is adjusted through the length and inner diameter. Therefore, capillary tubes with different lengths and inner diameters need to be replaced in the performance matching stage to adjust the flow rate. The disadvantage of this device is that it is necessary to prepare a variety of capillary tubes with different lengths and inner diameters for debugging.

Flow adjustment with electronic expansion valve requires corresponding electrical control system to match, and the cost of electronic expansion valve is relatively high

In batch air-conditioning products, in addition to using capillary tubes and electronic expansion valves, more and more air-conditioning manufacturers use throttle valves for throttling in air-conditioning products due to cost and control reasons, while using capillary tubes or electronic expansion valves When the electronic expansion valve is matched and turned into mass production, it is necessary to use a throttle valve for equivalent throttling conversion. At present, there is no relevant calculation formula and empirical data, which brings difficulties to equivalent conversion.
