Problems solved by technology

[0002] In the traditional air conditioner industry, adjusting the output capacity of the air conditioner is mainly realized by changing the operating frequency of the air conditioner compressor. During the heating process, the indoor temperature is generally compared with the target indoor temperature set by the user to judge whether it is necessary to shut down. However, when this method is used for control, due to the unevenness of the indoor air flow, the output of the air conditioner in the actual situation The wind needs a certain period of time to exchange heat with the indoor environment. Therefore, when cooling, it is easy to cause the actual indoor temperature to be lower than the target indoor temperature. When heating, the actual indoor temperature is likely to be higher than the target indoor temperature Overheating of temperature, whether it is too cold or too hot, affects the user experience and causes energy waste

Embodiment 1

[0090] In the existing technology, when the air conditioner is running, it is determined whether the compressor is stopped according to the target indoor temperature set by the user and the current actual indoor temperature. However, the air conditioner detects the indoor temperature through the sensor of the air return port of the air conditioner, due to the lag of heat transfer However, when the temperature of the return air outlet is equal to the target indoor temperature, the room is already in a state of overcooling or overheating, that is, the indoor temperature is often overcooled or overheated, resulting in reduced user experience and wasting power. To solve the above problems, the present application proposes a control method for an air conditioner compressor, such as figure 1 As shown, the method proposed in this application includes:

[0091] The detection step is to obtain the target indoor temperature, the first indoor temperature and the air outlet temperature of...

Embodiment 2

[0131] In order to better illustrate the beneficial effects of the present application, a preferred embodiment is proposed below.

[0132] In this embodiment, after the user sets the target indoor temperature of the air conditioner, it is assumed that it is in cooling mode, the air conditioner is turned on, and the absolute value ΔT of the difference between the target indoor temperature and the current indoor temperature (second indoor temperature) is detected 3 , according to ΔT 3 Determine the frequency of the air conditioner compressor (reference operating frequency). For example, the frequency of the compressor can be set to five frequency blocks, and different frequency blocks correspond to different frequencies, which are UHF f 5 , medium and high frequency f 4 , high frequency f 3 , middle and low frequency f 2 and low frequency f 1 , and then determine the reference operating frequency according to the rules shown in Table 1, and control the air conditioner to run...

Abstract

The invention provides an air conditioner compressor control method and device and an air conditioner. The air conditioner compressor control method comprises the steps that detecting is conducted, specifically, the target indoor temperature, the first indoor temperature and the air conditioner air exhaust temperature when the air conditioner operates in the set mode are obtained; computing is conducted, specifically, the first difference value between the target indoor temperature and the first indoor temperature is determined, and the second difference value between the air conditioner air exhaust temperature and the first indoor temperature is determined; and adjusting is conducted, specifically, the target operation frequency of a compressor is determined according to the first difference value and the second difference value, and the compressor is adjusted to the target operation frequency, wherein the larger the absolute value deltaT1 of the first difference value is and / or the larger the absolute value deltaT2 of the second difference value is, the higher the target operation frequency is. Accordingly, the problems that in the prior art, the indoor temperature is adjusted tobe too low in the refrigerating mode and too high in the heating mode, thus, energy consumption is high, and the user experience is poor are solved.
