Problems solved by technology

[0002] Existing air-conditioning units do not have special refrigerant balance detection or monitoring devices, and the refrigerant balance of the air-conditioning unit cannot be obtained in real time for users or maintenance personnel to check
[0003] Based on this, when the air conditioning unit fails, such as when the air conditioner is blowing air but not cooling, the user or maintenance personnel cannot know the current refrigerant balance of the air conditioning unit, and cannot determine whether the current fault is caused by insufficient refrigerant. , which ultimately brings unfavorable factors to the user's fault report or maintenance personnel's troubleshooting

Embodiment 1

[0041] Embodiment 1 of the present invention discloses a refrigerant residual detection method, the detection method can be applied to air conditioners, refer to figure 1 , the method may include the following steps:

[0042] S101: Real-time acquisition of preset refrigerant parameter values ​​at preset positions of the air-conditioning unit and preset auxiliary parameter values ​​of the air-conditioning unit.

[0043] Wherein, the preset refrigerant parameter value obtained in real time at the preset position of the air conditioning unit in this step is specifically the current refrigerant density value at the preset position, and the preset auxiliary parameter value obtained in real time includes the current ambient temperature value of the air conditioning unit and the current set temperature value.

[0044] refer to figure 2 In the structural diagram of the air conditioning system shown, in this embodiment, a density sensor is preset at a preset position A on the refrig...

Embodiment 2

[0076] This embodiment discloses a refrigerant residual detection device, refer to image 3 , the device includes a parameter acquisition module 100 , a balance calculation module 200 and a display control module 300 .

[0077] The parameter acquiring module 100 is used to acquire the preset refrigerant parameter value of the preset position of the air conditioning unit and the preset auxiliary parameter value of the air conditioning unit in real time.

[0078] Wherein, the preset refrigerant parameters include the current refrigerant density, and the preset auxiliary parameters include: the current ambient temperature and the current set temperature of the air conditioning unit.

[0079] The parameter acquisition module 100 includes a first acquisition unit, configured to acquire the current refrigerant density value at a preset position in the refrigerant outlet pipe of the compressor in real time through a density sensor.

[0080] The remaining amount calculation module 20...

Embodiment 3

Abstract

The invention discloses a refrigerant allowance detecting method, a refrigerant allowance detecting device and an air conditioner. According to the method, the device and the air conditioner, the method comprises the following steps: obtaining preset refrigerant parameter values which are preset in an air conditioning unit, and preset auxiliary parameter values of the air conditioning unit in real time; and computing, based on the preset refrigerant parameter values and the preset auxiliary parameter values which are obtained in real time, the refrigerant allowance of the air conditioning unit; and finally, controlling and displaying the refrigerant allowance for a user or a maintenance personnel to check. The refrigerant allowance detecting method realizes real-time detection and display of the refrigerant allowance of the air conditioning unit, so that the user or the maintenance personnel knows the refrigerant allowance of the air conditioning unit in real time, and therefore, when the air conditioning unit breaks down, convenience is provided for malfunction service of the user or malfunction elimination of the maintenance personnel.

Description

technical field [0001] The invention belongs to the technical field of parameter detection of air-conditioning units, and in particular relates to a refrigerant residual detection method, device and air conditioner. Background technique [0002] Existing air-conditioning units do not have a special detection or monitoring device for the residual refrigerant of the air-conditioning unit, and cannot obtain the residual refrigerant of the air-conditioning unit in real time for users or maintenance personnel to check. [0003] Based on this, when the air conditioning unit fails, such as when the air conditioner is blowing air but not cooling, the user or maintenance personnel cannot know the current refrigerant balance of the air conditioning unit, and cannot determine whether the current fault is caused by insufficient refrigerant. , which ultimately brings unfavorable factors to the user's fault repair or maintenance personnel's troubleshooting.
