Control method of portable air conditioner, portable air conditioner and control device

Abstract

The invention discloses a control method of a portable air conditioner, the portable air conditioner and a control device. The control method comprises the steps that in the operation process of the portable air conditioner, if it is determined that the portable air conditioner is switched from a highest air gear to a lowest air gear, the indoor environment temperature is obtained; and when the indoor environment temperature is larger than or equal to a preset temperature threshold value, the rotating speed of an inner draught fan and the operation frequency of a compressor are controlled to be synchronously reduced, the rotating speed of an outer draught fan is controlled to be delayed to be reduced, and the inner draught fan and the outer draught fan finish the speed reduction action at the same time. According to the control method of the portable air conditioner, the portable air conditioner and the control device, therefore, if it is determined that the portable air conditioner is switched from the highest air gear to the lowest air gear, when the indoor environment temperature is larger than or equal to the preset temperature threshold value, the rotating speed of the inner draught fan and the operation frequency of the compressor are controlled to be synchronously reduced, the pressure in a portable air conditioner system can be rapidly reduced, and then the rotating speed of the outer draught fan is controlled to be reduced; therefore, the pressure in the portable air conditioner system cannot rebound and rise, and the protective shutdown of the portable air conditioner when a user lowers the air gear can be avoided.

Description

technical field [0001] The present invention relates to the field of air conditioners, in particular to a control method for a portable air conditioner, a computer-readable storage medium, a portable air conditioner and a control device for the portable air conditioner. Background technique [0002] Portable air conditioners are used in many scenarios due to their portability and compactness, such as outdoors, kitchens and offices. Portable air conditioners generally have multiple windshields. Users generally choose different windshields in different scenarios. For example, in office scenarios, users generally choose silent windshields, while in outdoor or kitchen scenarios, users generally choose the strongest windshields. Or users will choose different windshields according to their needs in the same scene. [0003] In related technologies, users will inevitably switch between different windshields during the use of the portable air conditioner, for example, controlling t...

[0004] Moreover, during the gear switching process, the pressure in the portable air conditioner system drops slowly, and the pressure in the portable air conditioner system tends to rebound and rise after the pressure drops. At the same time, the portable air conditioner makes a lot of noise, which affects the comfort of the portable air conditioner. sex
