Embodiment 1

[0025] This embodiment provides an air conditioner defrosting method, which is applied to a multi-fan air conditioner. A multi-fan air conditioner generally has an upper air outlet and a lower air outlet. This method is used to ensure that the above-mentioned multi-fan air conditioner is in the defrosting mode. , to reduce the impact on the indoor temperature and ensure the comfort of the user. What needs to be explained here is that this method is based on the technical improvement given by the air-conditioning hot gas bypass defrosting principle in the prior art. At the same time, before entering the defrosting process , the multi-fan air conditioner is placed in the heating mode of the user's use stage, such as figure 1 Shown is a flow chart of the air conditioner defrosting method provided in this embodiment. The method includes the following steps:

[0026] S1: Obtain the current indoor ambient temperature. The air conditioner is equipped with a temperature control devic...

Embodiment 2

[0053] This embodiment provides an air conditioner, including: a compressor, an indoor heat exchanger, an outdoor heat exchanger, an upper air outlet, a lower air outlet, and a controller.

[0054] The controller is used to implement the method for defrosting the multi-fan air conditioner in the first embodiment above. The controller includes one or more processors 11 and memory 12, Figure 6 A processor 11 is taken as an example.

[0055] The controller may also include: an input device 13 and an output device 14 .

[0056] The processor 11, the memory 12, the input device 13 and the output device 14 can be connected via a bus or in other ways, Figure 6 Take connection via bus as an example.

[0057] The processor 11 may be a central processing unit (Central Processing Unit, CPU). Processor 11 can also be other general-purpose processors, digital signal processor (Digital Signal Processor, DSP), application specific integrated circuit (Application Specific Integrated Cir...

Abstract

The invention provides a multi-fan air conditioner defrosting method and an air conditioner. The air conditioner defrosting method is used for a multi-fan air conditioner, and comprises the steps of acquiring a current indoor ambient temperature; calculating the difference value Delta T between the current indoor ambient temperature and a user preset ambient temperature; comparing the Delta T witha preset temperature difference value Delta T0 under a hot air defrosting condition to determine whether a hot air defrosting condition is satisfied or not; and if the hot air defrosting condition issatisfied, at the time, reducing the air outlet amount per unit time of an upper air outlet and a lower air outlet, and making the air outlet amount per unit time of the upper air outlet less than the air outlet amount per unit time of the lower air outlet to enter a defrosting mode. According to the multi-fan air conditioner defrosting method and the air conditioner, the problems of great indoorambient temperature fluctuation and poor body sense of user caused during defrosting process of the air conditioner are solved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a multi-fan air conditioner defrosting method and an air conditioner. Background technique [0002] When the heat pump air conditioner is used in a low-temperature and high-humidity area, when it is running in the heating mode, the outdoor heat exchanger is prone to frost, which requires periodic defrosting. Due to the frequent operation of frosting and defrosting, the heat output is discontinuous, resulting in poor comfort of heating and defrosting. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art that the indoor heat supply of the air conditioner is discontinuous in the defrosting mode, resulting in large fluctuations in the indoor temperature and poor physical sensation of the human body, thereby providing a multi-fan air conditioner defrosting method and air co...
