Title:
FLUORINE DEFICIENCY DETERMINATION METHOD AND CONTROL METHOD FOR AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2020/134103
Kind Code:
A1
Abstract:
The present invention relates to the technical field of air conditioning, and aims to solve the problems of not being able to easily and accurately determine fluorine deficiency in existing air conditioners and not being able to adaptively adjust the operation state of air conditioners according to the degree of fluorine deficiency. Hence, the present invention provides a fluorine deficiency determination method and control method for an air conditioner. The control method comprises the following steps: obtaining air outlet temperatures at a first air outlet and a second air outlet, and calculating the temperature difference therebetween; comparing the temperature difference with a preset temperature difference threshold; and adjusting the opening degree of an expansion valve according to the comparison result. According to the control method provided by the present invention, the opening degree of the expansion valve can be automatically adjusted according to the temperature comparison result, the fluorine flow is compensated to enhance the cooling or heating efficiency of an air-conditioning system, so as to realize self-adaptive adjustment of the air conditioner, thereby guaranteeing the cooling or heating efficiency of the system in a slight fluorine deficiency and effectively reducing energy consumption. The fluorine deficiency determination method provided by the present invention ensures higher accuracy of the determination result and easier implementation.
