Embodiment 1

[0054] In order to achieve a better cooling effect, it is necessary to automatically adjust the ratio of sensible heat to latent heat, that is, the sensible heat ratio, according to the dry bulb temperature and wet bulb temperature of the current indoor environment. The temperature and humidity of the indoor environment should reach the level most suitable for human activities. The existing technology needs to detect the current humidity through the humidity sensor. The humidity sensor is installed at the air inlet panel. Adjusting the overall structure will have a negative impact on the structure of the internal unit of the air conditioner, making its structure complex, which is not conducive to design and production. At the same time, it will reduce the air volume of the incoming air and affect the cooling and heating effects of the air conditioner. Therefore, it is necessary to solve the problem of how to adjust the rotational speed of the inner fan according to the indoor ...

Embodiment 2

[0077] For ease of understanding, an example of the sensible heat ratio control method is provided below for illustration. In practical applications, the preset detection frequency will be set to obtain the temperature of the condensed water at each moment, so as to calculate the average value of the condensed water Temperature, by comparing the average temperature and the indoor ambient temperature with the preset relative humidity table, the indoor ambient humidity can be accurately obtained, avoiding the negative impact caused by the installation of the humidity sensor.

[0078] see figure 2 , Embodiment 2 of the sensible heat ratio control method shown in the embodiment of the present application includes:

[0079] 201. Control the compressor to start according to the preset frequency;

[0080] The preset frequency may be determined according to the outdoor ambient temperature and the preset frequency mapping table, and the outdoor ambient temperature is detected by a te...

Embodiment 3

[0092] For ease of understanding, an example of the sensible heat ratio control method is provided below for illustration. In practical applications, the indoor temperature level includes the first temperature level and the second temperature level. When the indoor temperature level is the first temperature level, The speed of the inner fan of the air conditioner will be adjusted according to the control strategy corresponding to the first temperature level.

[0093] see image 3 , Embodiment 3 of the sensible heat ratio control method shown in the embodiment of the present application includes:

[0094] 301. Comparing the indoor ambient humidity with the preset humidity, and determining whether to adjust the speed of the inner fan according to the comparison result;

[0095] In the embodiment of the present application, the indoor temperature level includes but is not limited to the first temperature level and the second temperature level, and the indoor temperature level ca...

Abstract

The invention relates to a sensible heat ratio control method. The method comprises the steps that a refrigeration mode switching instruction is received, and the indoor environment temperature is obtained; determining an indoor temperature level according to the indoor environment temperature; the operation frequency of a compressor of the air conditioner is monitored, and when the operation frequency reaches the preset frequency, the average temperature of condensate water in a condensate water storage device of the air conditioner within the preset duration is obtained; determining indoor environment humidity according to the average temperature, the indoor environment temperature and a preset relative humidity meter; and the rotating speed of an inner side fan of the air conditioner is adjusted according to the indoor environment humidity and the indoor temperature level. According to the scheme, the indoor environment humidity can be determined under the condition that a humidity sensor is not arranged, so that the rotating speed of the inner side draught fan is adjusted according to the indoor environment humidity and the indoor environment temperature, the effect of controlling the sensible heat ratio is achieved, and the indoor environment temperature and humidity reach the level suitable for human body activities.

Description

technical field [0001] The present application relates to the technical field of air conditioning, in particular to a sensible heat ratio control method and air conditioning electronic equipment. Background technique [0002] When the air conditioner is running in cooling mode, its cooling capacity consists of sensible heat and latent heat. Among them, the sensible heat is used to reduce the dry bulb temperature of the environment, that is, the higher the sensible heat, the greater the proportion of the total cooling capacity. The higher the cooling rate of the indoor environment, the better the cooling effect. Correspondingly, the latent heat is used to condense the moisture in the ambient air, that is, the higher the latent heat is, the larger the proportion of the total cooling capacity is, the faster the moisture in the indoor environment condenses, and the lower the air humidity is. Therefore, in order to achieve a better cooling effect, it is necessary to automaticall...
