specific Embodiment approach 1

[0037] Specific implementation mode one: combine figure 1 , figure 2 , image 3 , Figure 4 To describe this embodiment, a thermal comfort evaluation system based on a three-dimensional radiation environment provided in this embodiment includes: a data collection terminal 1, a data recording terminal 2, and a data processing terminal 3;

[0038] Such as figure 2 As shown, the data acquisition terminal 1 includes a support frame 1-1, six long-wave radiation flux density sensors 1-4 and six short-wave radiation flux density sensors 1-3; the support frame 1-1 is at the same height H In the six directions of up, down, east, west, south and north, respectively set a long-wave radiation flux density sensor 1-4 and a short-wave radiation flux density sensor 1-3, and a long-wave radiation flux density sensor 1-3 4 and the short-wave radiation flux density sensors 1-3 are respectively used for the collection of long-wave radiation flux density data and short-wave radiation flux d...

specific Embodiment approach 2

[0043] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the four radiation flux density sensors facing up and down (the radiation flux density sensor refers to the long-wave radiation flux density sensor and the short-wave radiation sensor) Flux density sensors, so there are four in total up and down) are located in the middle of the support frame 1-1 in the H height plane, and the other eight radiation flux density sensors facing east, west, south, and north directions are all located in the support frame 1-1 All around and facing outward; this ensures that all radiant flux density sensors will not be blocked and interfered. Among the eight radiant flux density sensors facing east, west, south and north, the distance between any two adjacent ones is between 0.3m and 0.5m; The measured three-dimensional radiation flux density data can represent the requirements of a measuring point under outdoor conditions, and achieve the pur...

specific Embodiment approach 3

[0045] Embodiment 3: The difference between this embodiment and Embodiment 2 is that the height H is 1.1 meters, which meets the measurement height requirement when thermal comfort is studied.

[0046] Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention provides a thermal comfort evaluation system based on a three-dimensional radiation environment and belongs to the technical field of thermal comfort evaluation. The system comprises data acquisition sides, a data recording side and a data processing side. The data acquisition sides are located in the upper, lower, eastern, western, southern and northern directions at the same heightH and are respectively provided with a long-wave radiation flux density sensor and a short-wave radiation flux density sensor; a radiation flux density recording instrument of the data recording sideis used for recording and storing obtained radiation flux density data; meanwhile, the data recording side can set sampling intervals of the data acquisition sides according to the demand; the radiation flux density data obtained from the data recording side is imported into a server of the data processing side through a movable storage module, the server processes the imported radiation flux density data to obtain thermal comfort parameters. The problem is solved that existing thermal comfort evaluation technology is low in accuracy and high in cost. The thermal comfort evaluation system canbe used for thermal comfort evaluation.

Description

technical field [0001] The invention relates to a thermal comfort evaluation system, which belongs to the technical field of thermal comfort evaluation. Background technique [0002] With the continuous development of urbanization and the gradual increase of urban population, the thermal environment and thermal comfort in urban space are the focus of domestic and foreign experts and scholars, and the outdoor radiation environment is an important part and hot issue. The impact of thermal comfort cannot be underestimated. Among them, the average radiation temperature is an important parameter determined by the radiation environment. It plays a key role in measuring the impact of the outdoor radiation environment on thermal comfort, and is also a necessary input for calculating thermal comfort indicators such as physiological equivalent temperature and general thermal climate index. quantity. [0003] At present, there are mainly three methods for calculating the average radi...
