Air conditioner and its control method and control device

Abstract

The invention discloses a control method and device of an air conditioner and the air conditioner. The method comprises the steps that the indoor environment temperature T1 is detected in real time after the air conditioner is started; the air conditioner is controlled to continuously run for the first preset time, and the indoor environment temperature obtained after the air conditioner continuously runs for the first preset time is recorded as T1Comp-one; according to the indoor environment temperature T1Comp-one, the running frequency of a compressor in the air conditioner is adjusted to be preset frequency; the compressor is controlled to continuously run for the second preset time at the preset frequency, and the indoor environment temperature obtained after the compressor continuously runs for the second preset time at the preset frequency is recorded as T1Comp-two; according to the indoor environment temperature T1Comp-two, the running frequency of the compressor is adjusted so that the indoor environment temperature T1 is in the preset temperature interval. According to the control method, the air conditioner can run in the energy-saving and comfortable state, and therefore the energy-saving and comfortable effect is achieved better.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method, a control device and an air conditioner with the control device. Background technique [0002] In the related art, the control method of the inverter air conditioner usually uses the user's set temperature and the indoor ambient temperature as control parameters, and controls the operating frequency of the compressor in the air conditioner according to the difference between the set temperature and the indoor ambient temperature. For example, when the indoor ambient temperature is equal to or lower than the set temperature, the operating frequency of the compressor of the inverter air conditioner is continuously reduced to the lowest operating frequency. [0003] In order to improve the energy efficiency of the inverter air conditioner, there is also a control method for the inverter air conditioner, which is to control the operating fr...

AI Technical Summary

Problems solved by technology

[0004] However, in the above two methods, the operating frequency of the compressor is usually low or high during the entire operation of the air conditioner, which cannot achieve better energy-saving effects and affects comfort.

Especially household frequency conversion air conditioners with a large number of horses, such as household frequency conversion cabinets, are used in the living room and have a large application area. Consumers generally have the habit of shutting down after starting up for a certain period of time (such as 4 hours). Therefore, in such occasions Under such circumstances, the existing technical solutions cannot achieve the purpose of energy saving and comfort
