Referring to fig. 3, an embodiment of the present disclosure provides a control method for a dual evaporator air conditioner, including the steps of:
s301: and obtaining a first wind shield of the first fan and a second wind shield of the second fan.
And S302, under the condition that the first wind gear is larger than the second wind gear, correcting the current operating frequency of the compressor according to the first wind gear and the second wind gear to obtain a target operating frequency, and correcting the current opening of the second regulating valve to obtain a target opening.
And S303, judging whether the target running frequency of the compressor is less than the current running frequency.
And S304, under the condition that the target operation frequency of the compressor is less than the current operation frequency, adjusting the operation frequency of the compressor according to the target operation frequency, and after a first preset time period, adjusting the opening of the second adjusting valve according to the target opening.
Here, the first preset duration is in a range of [1min, 3min ], such as 1min (minute), 2min, 3 min. When the operation frequency of the compressor is reduced, the opening degree of the regulating valve is also reduced in order to ensure the proper exhaust temperature and heat exchange efficiency of the air conditioner. Therefore, if the opening of the second regulating valve is reduced first, the pressure of the air conditioning system is increased, the exhaust temperature of the air conditioning system is increased, and high-temperature exhaust protection may occur, which may cause an abnormal situation. Therefore, when the target operation frequency of the compressor is smaller than the current operation frequency, the opening degree of the second regulating valve is regulated after the first preset time of the operation frequency of the compressor is regulated according to the target operation frequency, and the operation reliability of the double-evaporator air conditioner can be improved.
And S305, under the condition that the target operation frequency of the compressor is greater than the current operation frequency, adjusting the opening of the second adjusting valve according to the target opening, and after a second preset time, adjusting the operation frequency of the compressor according to the target operation frequency.
Here, the second preset time period has a value range of [30s, 80s ], for example, 30s (second), 40s, 50s, 60s, 70s, 80 s. When the running frequency of the compressor needs to be increased, the opening degree of the second regulating valve is regulated first, so that the phenomenon of high-temperature protection of exhaust gas caused by the fact that the system pressure is increased due to the fact that the compressor is increased in frequency can be effectively reduced.
In the embodiment of the disclosure, by optimizing the operation frequency control of the compressor of the dual-evaporator air conditioner and the flow control of the evaporator positioned at the low-wind-level air outlet, the uniformity of the air outlet temperature of the two air outlets of the dual-evaporator air conditioner can be improved, and the use experience of a user is improved; meanwhile, the occurrence of the exhaust high-temperature protection phenomenon caused by the rise of the system pressure due to the rise of the frequency of the compressor is effectively reduced by limiting the operation frequency of the compressor and the adjusting sequence of the opening of the second adjusting valve, and the operation reliability of the double-evaporator air conditioner can be improved.
