In this paper, temperature fluctuation in the room which was tested in which environment is built by the domestic air conditioner Different air conditioning set temperature may cause different temperature fluctuation in each position. From the subjective assessment results it can be known that, under the thermal comfort environment condition, the biggest acceptable temperature fluctuation is obtained and is 0.6 °C in summer and 0.8 °C in winter. In summer working condition, temperature fluctuation in each test point is compared with the acceptable temperature fluctuation (0.6 °C) and then the satisfaction rate for each working condition can be obtained. The test results show that the highest satisfaction rate about temperature fluctuation is 94% when the indoor air temperature is about 26 °C. Air temperature higher or lower than 26 °C will reduce the satisfaction rate about temperature fluctuation. Working condition in the winter, using the same method, the satisfaction rate about temperature fluctuation for each working condition can be obtained, it is higher than the summer, it can reach to 90% in every working condition. It is because that tester wears a lot of clothes in winter, the clothes can reduce the body’s sensitivity to the environment temperature changes. Test results are matched well with subjective assessment. The research in this article can provide basis for thermal comfort evaluation of typical residential air conditioning room and also can guide the design of air condition system in order to ensure the thermal comfort of the room. |
