[0002] When the air conditioning unit refrigeration operation enters the oil return mode, the frequency of the variable frequency compressor will change, and the frequency will increase or decrease to the set oil return frequency. The frequency change of the compressor will cause the change of the refrigeration capacity and the dehumidification capacity of the air conditioning unit, which will cause the change of the indoor environment which has reached dynamic balance. For places with high requirements for temperature and humidity, the constant temperature and humidity requirements cannot be met.

[0034] The application will be further described below with reference to the drawings. The following examples are only used to more clearly illustrate the technical solutions of the application, and cannot be used to limit the protection scope of the application.

[0035] Through analysis, the patent application in the background art can effectively realize constant temperature adjustment by adjusting through electric heating, but due to the form of electric heating, the demand for constant humidity cannot be met. The design idea of the present application is to introduce an electrode humidifier into the air conditioning unit, and use the advantage that the electrode humidifier can be quickly adjusted to solve the problem that the humidity is difficult to adjust when the air conditioning unit is in the oil return mode in the refrigeration operation, and the demand for constant temperature and humidity of the air conditioning unit is met through humidity adjustment.

[0036] Embodiment 1

[0037] As Figure 1 shown, the application provides a constant temperature and humidity control method for air conditioning unit, comprising the following steps:

[0038] Step 10, connecting the electrode humidifier to the air conditioning unit.

[0039] Step 20, obtaining the oil return setting frequency P 回油 , the maximum frequency P 最高 and the running frequency P 运行 of the variable frequency compressor in the air conditioning unit.

[0040] Step 30, when the air conditioning unit enters the oil return mode in refrigeration operation, calculating the adjustment parameter A according to the oil return setting frequency P 回油 , the maximum frequency P 最高 and the running frequency P 运行 .

[0041] Step 40, adjusting the output power of the electrode humidifier in the air conditioning unit according to the adjustment parameter A.

[0042] The application can quickly adjust the humidity in the room by adjusting the output power of the electrode humidifier connected in the air conditioning unit, can maximize the maintenance of the temperature and humidity in the room, and ensures the constant temperature and humidity requirement of the air conditioning unit.

[0043] The application will be described below through a specific embodiment.

[0044] Step 10, connecting the electrode humidifier to the air conditioning unit.

[0045] In this step, the output port of the electrode humidifier is installed in the room to realize the gas output in the room, ensure the adjustment of the output in the room, and the controller of the electrode humidifier can be connected with the controller signal in the air conditioning unit to realize the control of the electrode humidifier.

[0046] Step 20, obtaining the oil return setting frequency P 回油 , the maximum frequency P 最高 and the running frequency P 运行 of the variable frequency compressor in the air conditioning unit.

[0047] In this step, the oil return setting frequency P 回油 and the maximum frequency P 最高 are related to the parameters of the variable frequency compressor, which can be obtained by pre-acquisition, and the running frequency P 运行 of the variable frequency compressor is obtained by real-time acquisition through the sensor.

[0048] Step 30, when the air conditioning unit enters the oil return mode in refrigeration operation, calculating the adjustment parameter A according to the oil return setting frequency P 回油, the highest frequency P 最高 and the running frequency P 运行 , the adjustment parameter A is calculated.

[0049] In this step, the expression formula of the adjustment parameter A is:

[0050]

[0051] In the formula, P 回油 represents the oil return set frequency of the variable frequency compressor; P 最高 represents the highest frequency of the variable frequency compressor; P 运行 represents the running frequency of the compressor before oil return; and β represents a set coefficient, and the set coefficient β ranges from 0.7 to 1.4.

[0052] Step 40, adjusting the output power of the electrode humidifier in the air conditioning unit according to the adjustment parameter A.

[0053] The adjustment parameter A is judged, and the output power of the electrode humidifier is adjusted differently according to the adjustment parameter A. When A≤-20%, the output power of the electrode humidifier is controlled to be reduced by 20%; when 20%<A≤-5%, the output power of the electrode humidifier is controlled to be reduced by 10%; when -5%<A<5%, the electrode humidifier maintains the current output power; when 5%≤A<20%, the output power of the electrode humidifier is controlled to be increased by 10%; and when A≥20%, the output power of the electrode humidifier is controlled to be increased by 20%.
