Embodiment Construction

[0047] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. For example, although the fourth fitting formula of the frequency-up speed of the compressor in the specific implementation is v y = kT ao +b is shown as an example, but the form of this fitting formula is not static, and those skilled in the art can adjust it according to needs, so as to adapt to specific applications. For example, the fourth fitting formula can also be v y =k Tao +b(0

[0048] First of all, it needs to be explained that generally air conditioners include indoor units and outdoor units. The indoor units are equipped with indoor heat exchangers and indoor fans. , The compressor is equipped with an electric heater ...

Abstract

The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioner in a heating mode. By adoption of the control method of the air conditioner inthe heating mode, the problems of poor universality and poor user experience of an existing control method of an air conditioner are solved. The control method of the air conditioner in the heating mode comprises the steps that the outdoor environment temperature and the outdoor environment humidity are obtained; when the outdoor environment temperature is lower than or equal to a temperature threshold, the preheating time of an electric heater is calculated according to a first fitting formula; the closing speed of an expansion valve is calculated according to a second fitting formula; the advanced start time of an outdoor fan is calculated according to a third fitting formula; the frequency increase speed of a compressor is calculated according to a fourth fitting formula; the electricheater, the expansion valve and the outdoor fan are controlled to operate; and when the electric heater / expansion valve / outdoor fan meets set conditions, the frequency of the compressor is controlledto be increased at the frequency increase speed. By adoption of the control method of the air conditioner in the heating mode, the universality of the air conditioner can be improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for controlling an air conditioner in a heating mode. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality of life, and this requirement is particularly evident in household appliances. Taking an air conditioner as an example, in order to meet the needs of users for rapid heating and thus bring users a comfortable experience, when the existing air conditioner is just turned on, the frequency of the compressor is generally increased to a higher frequency (such as frequency to the maximum operating frequency). In the process of the compressor rapidly rising to high frequency, in order to ensure normal oil return, the compressor is usually forced to continue running at a certain or certain fixed frequency (oil return frequency) for a period of time, and continue to increase the frequency...
