Embodiment 1

[0040] Such as figure 1 As shown, the present invention discloses an adjustment device for the circulation volume of air-conditioning refrigerant. On the basis of the structure in which the original main throttling device 7 of the air-conditioning refrigerant circulation system is respectively connected to the liquid inlet pipe 1 and the liquid outlet pipe 5, the present invention makes the following improvements : The regulating device is connected in parallel with the main throttling device 7 in the refrigerant circulation system. The regulating device includes a solenoid valve 2, an auxiliary throttling device 6 and a liquid storage tank 4. The solenoid valve 2 and the auxiliary throttling device 6 are connected in series through a connecting pipe. The connecting pipe between the solenoid valve 2 and the auxiliary throttling device 6 communicates with the liquid storage tank 4 .

[0041] In this embodiment, the solenoid valve 2 and the auxiliary throttling device 6 are sequ...

Embodiment 2

[0052] This embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, at least two sets of adjustment devices are used in the adjustment method of the air-conditioning refrigerant circulation amount, specifically, there are at least two sets of adjustment devices in the adjustment method of the present invention, different The solenoid valve 2 in the regulating device has different preset solenoid valve opening values ​​and / or different preset solenoid valve closing values; the regulating system of the air-conditioning refrigerant circulation amount of the present invention includes at least two groups of regulating devices connected in parallel, at least two The regulating device is connected in series between the liquid inlet pipe 1 and the liquid outlet pipe 5 .

[0053] More specifically, the present invention is provided with a solenoid valve 2 at the front end of the liquid storage tank 4. For the convenience of description, in this embo...

Abstract

The invention discloses an adjustment device, system and method for the refrigerant circulation quantity of an air conditioner. The adjustment device comprises an electromagnetic valve, an auxiliary throttling device and a liquid storage tank. The adjustment system comprises a control device, a pressure acquisition device and the adjustment device. The adjustment method comprises the following steps that firstly, the current pressure values of any positions in a connecting pipe between an outlet of a compressor and a throttling valve are acquired; secondly, if the current pressure values are larger than a preset electromagnetic valve opening value, the third step is executed; and thirdly, the electromagnetic valve is opened, so that part of refrigerants are made to flow into the liquid storage tank automatically, the refrigerant circulation quantity of the air conditioner is reduced, and then the first step is executed. The adjustment device is connected with a main throttling device in a refrigerant circulation system in parallel. According to the adjustment device, system and method for the refrigerant circulation quantity of the air conditioner, the circulation quantity of refrigerants in the refrigerant system of the air conditioner is adjusted through the liquid storage tank, and the optimal matching between the refrigerant circulation quantity of an air conditioner system and the operating condition of the air conditioner is achieved.

Description

technical field [0001] The present invention relates to the technical field of air-conditioning manufacturing, and more specifically, the present invention relates to a device, system and method for adjusting the circulating volume of air-conditioning refrigerant. Background technique [0002] Generally speaking, existing air conditioners have both cooling and heating functions. For the air-conditioning refrigerant circulation system, under the two different working conditions of cooling and heating, the demand for refrigerant of the air conditioner is different. [0003] However, for existing air conditioners, once the air conditioner is delivered from the factory, the volume of refrigerant circulating in the air conditioner refrigerant circulation system is fixed. If you want to increase or decrease the volume of refrigerant circulated in the air conditioner refrigerant circulation system, you must disassemble the air conditioner. It is very inconvenient for users to add ...
