Control method and system for improving comfort of air conditioner sleeping mode

Abstract

The invention discloses a control method and system for improving the comfort of an air conditioner sleeping mode. The control method comprises the following steps that the gender and/or the age groupof a user are detected; the outdoor air temperature, the indoor air temperature and the indoor air humidity are collected in real time, the average of the outdoor air temperature and the indoor air temperature is set as the average radiation temperature, and a target temperature value is calculated by substituting clothing heat resistance, air velocity parameters and human body metabolic rate parameters into a PMV equation, wherein the clothing heat resistance and the air velocity parameters are preset by an air conditioner; and the frequency and operating mode of a compressor are adjusted through a 0.1-DEG C precise temperature control technology, and thus the temperature is adjusted to the target temperature. The precise target temperature value can be calculated through a fitting function, real-time precise adjustment can be achieved, and the heat comfort of the user under the sleeping state is significantly improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a control method and system for improving the comfort of an air conditioner in sleep mode. Background technique [0002] There are two ways to adjust the sleep mode of the existing air conditioner, the traditional sleep curve and pmv parameter control. The traditional sleep curve is generally obtained through a large number of medical experiments, and the corresponding comfortable temperature is set according to the user type, sleep time and relative humidity, but often The variation range of this comfortable temperature during 0.5h or 1h sleep time does not exceed 0.5 degrees Celsius, which makes it impossible to accurately and continuously realize a good comfortable sleep temperature change based on the existing temperature control technology. [0003] Although the general air conditioner is in the low wind speed cooling state when it is running in the slee...

[0002] There are two ways to adjust the sleep mode of the existing air conditioner, the traditional sleep curve and pmv parameter control. The traditional sleep curve is generally obtained through a large number of medical experiments, and the corresponding comfortable temperature is set according to the user type, sleep time and relative humidity, but often The range of change of this comfortable temperature in 0.5h or 1h sleep time does not exceed 0.5 degrees Celsius, which makes it impossible to accurately and continuously achieve a good comfortable sleep temperature change based on the existing temperature control technology

[0003] Although the general air conditioner is in the low wind speed cooling state when it is running in the sleep mode, it will still continue to dehumidify the room due to the low evaporation temperature of the indoor heat exchanger. Changes (awakening period, light sleep period, deep sleep period and rapid eye movement period), and changes in outdoor temperature at night will cause changes in various parameters in the pmv equation, such as average radiation temperature, etc. At this time, only indoor temperature and humidity are considered The pmv value calculated due to changes cannot accurately reflect the comfortable feel...
