Study On The Thermal Comfort Of Split Fabric Air Conditioner

With development of society and technology,more and more energy has been used efficiently.Meanwhile,people have a higher pursuit of the quality of life,especially the environment in the working and living areas.In order to solve this problem,this paper uses numerical simulation,experiment and questionnaire to study the impact of a split fabric air conditioner on human comfort.Through numerical simulation of the indoor temperature and speed of ordinary air conditioners,split fabric air conditioner with different rows of holes,different positions of outlets,and different installation positions of split fabric air conditioner to analyze the impact on human thermal comfort.Finally,through the experiment to study the comfort of the split fabric air conditioner,compared the results with the simulation,and investigate people’s degree of comfort satisfaction about the split fabric air conditioner with questionnaire.The following conclusions can be drawn:(1)The split fabric air conditioner makes the distribution gradient of temperature smaller,the distribution of velocity is more uniform,and the thermal comfort of the human’s activity area is even,there is also no blowing feeling.In contrast,ordinary air conditioners make indoor person feels a greater blowing sensation,and the thermal discomfort is obvious.(2)The three-row-hole spilt fabric air conditioner has uniform distribution of temperature and speed when air is supplied in room,and the human has no blowing sensation,also the thermal comfort is better;the single-row-hole spilt fabric air conditioner makes the head of the huaman a strong feeling of blowing,also thermal uncomfortable;double-row-hole spilt fabric air conditioner makes the indoor temperature higher and speed lower,although the distribution of temperature and velocity are uniform,it also makes the human thermal uncomfortable.(3)When the fabric duct of the split fabric air conditioner is installed in the middle-top of the room,the distribution of the temperature and speed are more evenly,and the human have a good thermal comfort with no sense of blowing,when the fabric duct is installed on the side of the top,the indoor temperature is relatively high,The air speed is lower,although there is no blowing sensation,but the human feel thermal uncomfortable.(4)Compared with the numerical simulation,the data of the experiment has a slightly higher temperature and a lower speed,but there is also a lower blowing sensation and better thermal comfort.(5)The result of the questionnaire shows that most people are satisfied with the split fabric air conditioner.Although someone is not satisfied,they also think that they can receive the split fabric air conditioner.On the whole,the split fabric air conditioner meets the comfort requirements of most people.
