Study On Energy Saving Mode Of Air Conditioning Behavior Based On Heat Tolerance

China is a big country in construction.With the development of building industry,the huge building energy consumption has attracted the attention of people from all walks of life.Although the energy saving building design standards have more and more strict requirements on the energy saving of buildings and electrical appliances,the energy consumption of buildings varies greatly due to the different behaviors and lifestyles of residents.This has led a growing number of researchers to recognize the importance of occupant behavior in building energy efficiency.The extensive popularization of air conditioning makes the energy consumption of air conditioning occupy a large proportion in the total energy consumption of buildings.However,habitant is right of air conditioning unreasonable use consumes a lot of energy consumption not only,and reduced human body to adapt ability,appeared even "air conditioning disease".Therefore,in order to reduce the energy consumption of air conditioning and avoid the health problems caused by long-term use of air conditioning,from the perspective of behavioral energy saving and human thermal health,it is necessary to reasonably establish human thermal comfort standards,properly play the thermal tolerance of human body,and take behavioral regulation as far as possible to achieve the purpose of cooling.Based on the above problems,the following studies are carried out in this paper.Firstly,from the perspective of behavioral energy saving and thermal health,an evaluation method of human thermal tolerance is developed.Then,10 men and 10 women were selected for laboratory study.A total of 5 experimental conditions(28/30/32/34/36℃)were set to investigate the subjective responses and physiological parameters under different behavior regulation modes(no regulation/electric fan/fan/wet towel).The results show that the thermal tolerance temperature without regulation is28.47℃,the thermal tolerance temperature of wet towel is 30.34℃,the thermal tolerance temperature of low grade fan is 29.84℃,the thermal tolerance temperature of fan is29.78℃,the thermal tolerance temperature of high grade fan is 31.13℃,and the thermal tolerance temperature of middle grade fan is 30.93℃.In the study condition,the body temperature of the subjects increases with the increase of air temperature,but the overall range of change is small.Heart rate,diastolic blood pressure and systolic blood pressure did not change with air temperature.In hot environment,appropriately increasing wind speed can reduce people’s thermal sensation and humidity sensation,and improve people’s satisfaction.With the increase of temperature,the cooling effect of fan behavior is better than that of unregulated behavior,which shows that people can adjust their behavior autonomously when adapting to the thermal environment.The behavior of wet towel has a certain cooling effect,but when the temperature exceeds 32℃,the evaporation heat dissipation will be affected,and the human body will feel more muggy and less comfortable.Finally,conduct a questionnaire survey on air conditioning behavior in Xi ’an area,and get the typical air conditioning behavior pattern in this area.On this basis,the energy saving effect of the air conditioning behavior mode based on human thermal tolerance in air conditioning behavior energy saving is verified.The results show that different behavior regulation can improve the temperature tolerance of human body in different degrees.When air conditioning is used for cooling,the improvement of thermal tolerance temperature can improve the tolerance temperature of air conditioning,shorten the service time of air conditioning,and achieve the purpose of reducing energy consumption of air conditioning.
