Embodiment 1
[0036] Such as figure 1 As shown, the first aspect of the present invention provides a control method for an air conditioning system, including:
[0037] S102: Based on the heating mode of the air conditioning system, obtain the system operating parameters within the preset oil return period, the accumulated operating time corresponding to the system operating parameters, and the outdoor ambient temperature;
[0038] S104: Based on the end of the preset oil return cycle, and when the system operating parameters, accumulated operating time, and outdoor ambient temperature all meet the heating oil return conditions, control the air conditioning system to perform oil return in the heating mode.
[0039] The control method of the air-conditioning system provided by the present invention monitors and acquires the system operating parameters of the air-conditioning system in a preset oil return cycle in real time when the air-conditioning system is operating in the heating mode, and...
Embodiment 2
[0045] On the basis of the first embodiment above, a compressor oil return model is established according to the system operating parameters of the air conditioning system and the corresponding oil level change data of the compressor.
[0046] In this embodiment, the oil return model of the compressor is a correspondence between system operating parameters and time thresholds of the air conditioning system. Specifically, according to the rated parameter characteristics of the compressor of the air conditioning system, the oil discharge rate of the compressor and the model of the air conditioning system under different operating parameters are obtained through theoretical calculation, and the oil return model of the compressor is obtained through multiple experimental tests and verifications. As well as theoretical calculations, the actual system operating parameters of the air conditioning system and a time threshold corresponding to the current parameters can be obtained throu...
Embodiment 3
[0057] On the basis of any of the above embodiments, the heating oil return condition further includes: the difference between the low pressure saturation temperature of the air conditioning system and the outdoor ambient temperature is greater than or equal to a preset threshold.
[0058] In this embodiment, when an oil return cycle ends, the low-pressure saturation temperature of the air conditioning system is compared with the outdoor ambient temperature at this time. If the difference is greater than or equal to a preset threshold, it is judged that the oil return cycle ends When , the low-pressure saturation temperature of the air-conditioning system and the outdoor ambient temperature meet the heating oil return conditions of the air-conditioning system. Specifically, the temperature difference between the low-pressure saturation temperature of the air-conditioning system and the outdoor ambient temperature is very small, and there will be no frosting, otherwise it is eas...
