Problems solved by technology

According to research, thermal comfort is not only related to temperature, but other factors need to be considered, such as humidity, wind speed, radiant temperature, human metabolic rate, fabric thermal resistance, etc. The mode regulates the temperature and cannot take into account other factors, so it is naturally difficult to truly meet the comfort needs

experiment example 1

[0082] Please also refer to figure 2 and Figure 5 , taking the predicted average voting index as the temperature sensitivity index I, which is a function of six variables such as air temperature, relative humidity, wind speed, average radiant temperature, clothing worn by the user or the thermal resistance of fabrics such as bedding, and human metabolic rate. Therefore, the temperature sensitivity index I is calculated by taking fabric thermal resistance and human metabolic rate as the user parameter value Pu, and air temperature, relative humidity, wind speed, and average radiation temperature as the environmental state parameter value Pe. User A’s clothes are short-sleeved shorts, the bed is a mattress plus a summer mat, and the quilt is covered with a thin quilt. Generally speaking, the body surface coverage of user A’s bed and quilt is about 60%. The thermal resistance is 0.282℃·m 2 / W). According to sleep time and basal metabolic rate data, it is estimated that user ...

experiment example 2

[0084] Continuing from Experiment 1, assume that there is an electric fan in the use environment, and the control of the electric fan only has two options of on and off. Assume that the average wind speed on the body surface of user A is estimated to be about 0.2m / s when the electric fan is turned on, and the average wind speed of user A when the electric fan is off The average wind speed on the body surface is still set at 0.1m / s. At this time, the controllable parameters affecting the environmental state parameter value Pe in the temperature-sensing index I become two kinds of wind speed and air temperature, so in this case, the control module 40 will control all possibilities of the two controllable parameters of wind speed and air temperature. Calculate the parameter combination of the situation one by one to find the parameter combination that makes the temperature index closest to the optimal temperature index. Set at 26°C and run the fan.

Abstract

A sleeping environment control system and method includes sensing a condition of environment to obtain a value of an environmental condition parameter, and then generating a value of a thermal sensation indicator according to the value of the environmental condition parameter. A physiological status of a user is sensed to obtain a value of a physiological status parameter. After a plurality of values of the thermal sensation indicator and a plurality of values of the physiological status parameter are collected, a regression analysis is performed to obtain a best value of the thermal sensationindicator according to the plurality of values of the thermal sensation indicator and the plurality of values of the physiological status parameter. A value of an environmental condition setting parameter is adjusted according to the best value of the thermal sensation indicator.

Description

technical field [0001] The invention relates to the field of environment control, in particular to a sleep environment control system and a control method thereof. Background technique [0002] Generally speaking, almost everyone has the experience of waking up from cold or hot. According to research, 60% of air-conditioning users in Hong Kong, which has a subtropical climate and uses reinforced concrete to build houses, said they had woken up during sleep. According to research, thermal comfort is not only related to temperature, but other factors need to be considered, such as humidity, wind speed, radiant temperature, human metabolic rate, fabric thermal resistance, etc. The mode regulates the temperature and cannot take into account other factors, so it is naturally difficult to truly meet the comfort needs. [0003] On the other hand, the phenomenon of cold awakening or hot awakening shows that sleep is not unresponsive to warm environmental conditions, but how to def...
