Problems solved by technology

[0002] At present, the adjustment of the indoor temperature of the air conditioner is generally realized through the frequency of the compressor, the speed of the fan or the opening of the throttle valve, so that the indoor ambient temperature reaches the set temperature, but the coordination between the various operating parameters of the air conditioner is not good. Good, and without controlling the indoor humidity and airflow speed, the comfort inside the room cannot meet the requirements, affecting the comfort of users

Embodiment 1

[0045] The physiological functions of the human body, such as heat balance function, temperature regulation, endocrine system, and digestive organs, are comprehensively affected by various meteorological factors. Human comfort (SSD) is a commonly used method to characterize human comfort in daily life. It mainly depends on three indicators: temperature, humidity and wind speed. Temperature is the main indicator, and humidity and wind speed are auxiliary indicators.

[0046] The calculation formula is:

[0047] SSD=(1.818T+18.18)(0.88+0.002F)+(T-32) / (45-T)-3.2V+18.2;

[0048] In the formula, SSD is the human comfort index, T is the indoor temperature, F is the relative humidity, and V is the wind speed.

[0049] The indoor temperature is generally detected by the temperature sensor at the return air outlet of the air conditioner, and the temperature detected by an infrared sensor or a wearable smart device can also be used as the indoor temperature.

[0050] The relative humidi...

Embodiment 2

[0105] The invention also discloses a control device, which includes a memory, a processor, and an air conditioner control program stored in the memory and operable on the processor. When the air conditioner control program is executed by the processor The steps of the method for controlling the operation of the inverter air conditioner described in Embodiment 1 are realized.

[0106] The present invention also discloses an air conditioner, which includes the above-mentioned control device.

Abstract

The invention provides a variable frequency air conditioner operation control method and device and an air conditioner. The variable frequency air conditioner operation control method comprises the following steps: S1, the air conditioner enters an automatic control mode, and human body comfort related parameters in an action space of the air conditioner are obtained; S2, a set temperature Tsetting is obtained, and a human body comfort index adjusting stage enters; S3, the SSD value is calculated, if SSD is larger than or equal to ssd1 and smaller than or equal to ssd2, T setting is not changed, and otherwise, T setting is adjusted; S4, if F is larger than or equal to f1 and smaller than or equal to f2, the T evaporator target is not changed, and otherwise, the T evaporator target is adjusted; S5, if V is larger than or equal to v1 and smaller than or equal to v2, the rotating speed of a motor is not changed, otherwise, the rotating speed of the motor is adjusted; and S6, the air conditioner is controlled to operate according to the output motor rotating speed, the T evaporator and the T evaporator target, and after the operation time is Q, the step S3 is executed. Through a SSD formula, the temperature, the relative humidity and the airflow speed in the room are continuously adjusted, so that the SSD value, the relative humidity and the wind speed are within the comfortable range, the body feeling is good, and the comfort degree is high.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an operation control method, a control device and an air conditioner of an inverter air conditioner. Background technique [0002] At present, the adjustment of the indoor temperature of the air conditioner is generally realized through the frequency of the compressor, the speed of the fan or the opening of the throttle valve, so that the indoor ambient temperature reaches the set temperature, but the coordination between the various operating parameters of the air conditioner is not good. Good, and if the indoor humidity and airflow speed are not controlled, the comfort inside the room will not meet the requirements, which will affect the comfort of users. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [00...
