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
[0087] Embodiment 3 discloses an air conditioner, and the air conditioner includes the device for detecting the remaining amount of refrigerant as disclosed in Embodiment 2. Based on the refrigerant residual detection device, the air conditioner can detect the refrigerant residual of the unit in real time during the operation of the unit, so that it is convenient for users or maintenance personnel to know the refrigerant status of the unit at any time, and at the same time report for the user's failure Or the troubleshooting work of maintenance personnel provides a favorable factor.
