All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] The following detailed description of the features and performance of the overall performance environment simulation cabin structure and system of this application, in conjunction with embodiments, provides further insight into the specifics.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, this application embodiment provides an overall performance environment simulation cabin structure, which includes a main support structure 100, a driving system 110 connected to the main support structure 100, a wind box 120 connected to the bottom of the driving system 110, an annular enclosure membrane 130, an annular track 150 connected to the bottom of the driving system 110, four spaced-apart suspension mechanisms 140 and an environmental control device 200. The main support structure 100 serves as the load-bearing frame of the overall performance environment simulation chamber and can be a steel frame. Two trolley tracks 190 are respectively installed at both ends of the top inner wall of the main support structure 100. The trolley system 110 is rotatably mounted on the two trolley tracks 190 at both ends, allowing it to move along the tracks for lifting test objects such as residences and other auxiliary equipment. The air box 120, as an air distribution static pressure box, is fixedly connected to the bottom of the trolley system 110 and can move with it. The bottom of the air box 120 is connected to spaced-apart air outlets 121, spaced-apart rain nozzles 122, and spaced-apart snow nozzles 123. The enclosure membrane 130 is made of a soft, airtight composite material with good thermal insulation properties (such as thermal insulation tarpaulin, aerogel composite membrane, etc.). The enclosure membrane 130 is located below the wind box 120, and its bottom edge can be sealed to the ground. Thus, the wind box 120, the enclosure membrane 130, and the ground together form a closed test chamber 131. The aforementioned air outlet 121, rain nozzle 122, and snow nozzle 123 are all connected to the top of the test chamber 131 to regulate the internal climate environment of the test chamber 131.

[0027] Four hanging mechanisms 140 (e.g., winches or electric hoists) are slidably connected at their upper ends to the annular track 150, and at their lower ends to the top edge of the enclosure membrane 130. The four hanging mechanisms 140 drive the enclosure membrane 130 to rise and fall. When installing or removing the test object, the hanging mechanisms 140 lift the enclosure membrane 130 upwards and fold or retract it. Simultaneously, the trolley system 110 carries the bellows 120, the hanging mechanisms 140, and the enclosure membrane 130 to the waiting area, thus creating unobstructed space for the hoisting of the test object and solving the problems of large volume and difficult transportation and installation of traditional rigid simulation chambers. The hanging mechanisms 140 can move circumferentially along the annular track 150 and the enclosure membrane 130, allowing the position of the hanging points of the hanging mechanisms 140 to be adjusted according to actual needs when retracting or unfolding the enclosure membrane 130. This makes the lifting and lowering of the enclosure membrane 130 more stable and controllable, and facilitates tensioning or folding of the enclosure membrane 130.

[0028] The environmental control device 200 includes a temperature and humidity control device 210 and a rain and snow preparation device 220. The temperature and humidity control device 210 extracts air with low temperature stratification and uniform humidity from the bottom of the test chamber 131, adjusts the temperature and humidity, and then sends it into the top air box 120, which is then evenly distributed into the test chamber 131 through the air outlet 121. The rain and snow preparation device 220 delivers pressurized water to the rain nozzle 122 to simulate rainfall, and delivers pre-cooled water and compressed air to the snow nozzle 123 to spray ice crystals to simulate snowfall.

[0029] In this embodiment, the temperature and humidity control device 210 includes two temperature and humidity control boxes 211, a refrigeration device 230, and a closed cooling tower 240. Two temperature and humidity control boxes 211 are respectively located on both sides of the enclosure membrane 130. Each temperature and humidity control box 211 has an air inlet 212 and an air outlet 213 at one end and the top, respectively. Inside the temperature and humidity control box 211, there is an evaporator 214, a heater 215, a humidifier 216, and a blower 217 arranged sequentially between the air inlet 212 and the air outlet 213. The air inlet 212 is connected to the bottom of the test chamber 131 through a return air pipe 218. The air outlet 213 of the blower 217 is connected to the air box 120 through a blower pipe. The air at the bottom of the test chamber 131 passes sequentially through the return air pipe 218, the air inlet 212, the evaporator 214, the heater 215, the humidifier 216, the blower 217, the air outlet 213, and the blower pipe into the air box 120. The condenser 231 of the refrigeration equipment 230 is connected to the evaporator 214 through a refrigerant pipeline to form a compression refrigeration cycle. The condenser 231 and the closed cooling tower 240 are connected by cooling water pipes to form a cooling water circulation to remove the heat of condensation. Considering that the evaporator 214 is prone to frosting under low temperature conditions (such as during snowfall simulation), an electric defroster 219 is also connected to the evaporator 214 for timed or automatic defrosting.

[0030] The snow and rain preparation device 220 includes a snow and rain preparation box 221 and an air-cooled chiller unit 222, a cold water tank 223, a pure water tank 224, and an air compressor 225 installed inside it. The air-cooled chiller unit 222 is connected to the cold water tank 223 to form a circulation system, used to pre-cool the water in the cold water tank 223 to near freezing point (e.g., 1°C). The outlet of the cold water tank 223 is connected to each snow nozzle 123 through a first pressurization pump 226 and insulated pipes. The air compressor 225 is connected to each snow nozzle 123 through high-pressure air pipes. After the pre-cooled water and high-pressure air are mixed in the snow nozzle 123, they rapidly expand, atomize, and crystallize to form artificial snow crystals that are sprayed out to simulate snowfall. The pure water tank 224 is connected to each snow nozzle 122 through a second pressurization pump 227 and pipes to provide pure water for simulating rainfall.

[0031] To simulate lateral rain (such as simultaneous wind and rain), lateral sprinklers 180 are also provided on both sides of the inner wall of the enclosure membrane 130. The pure water tank 224 is connected to each lateral sprinkler 180 through the second booster pump 227 to spray water laterally.

[0032] To ensure uniform airflow and prevent excessive local wind speed from affecting the heat exchange state of the test object surface, the bottom of the air box 120 is provided with air outlet areas 124 arranged at intervals along its width. Each air outlet area 124 is provided with air inlets 121 arranged at intervals. The air inlets 121 are preferably perforated plates or nozzles, while the bottom perimeter of the test chamber 131 or the ground is provided with return air inlets connected to return air pipes 218, forming an airflow organization mode of "top air supply and bottom return air", which ensures the uniformity of the temperature and humidity field in the test chamber 131, and the indoor wind speed can be controlled below 0.2m / s, without affecting the steady-state heat transfer of the test object surface.

[0033] When testing the overall performance environment simulation chamber structure provided in this application embodiment, the entire residential building or large building component to be tested is first hoisted to the working platform inside the main support structure 100 by the crane system 110. Then, the crane system 110 moves to the top of the test chamber 131, and the hoisting mechanism 140 is activated to slowly lower the protective membrane 130 gathered at the top to the ground and seal it to form a closed test chamber 131. The environmental control device 200 is activated according to the required simulated climatic conditions. The temperature and humidity control device 210 draws air from the bottom of the test chamber 131 through the return air pipe 218. After cooling and dehumidifying by the evaporator 214, precise heating by the heater 215, and humidification by the humidifier 216, the air with regulated temperature and humidity is sent into the air box 120 by the air supply fan 217 and evenly delivered into the test chamber 131 through the air outlet 121 at the bottom of the air box 120. When rain or snow is required, the rain / snow preparation device 220 is activated, supplying water to the top rain nozzle 122 and side nozzles 180 via the pure water tank 224 and the second pressurizing pump 227 to simulate rainfall; and supplying pre-cooled water and compressed air to the snow nozzle 123 via the cold water tank 223, the first pressurizing pump 226, and the air compressor 225 to simulate snowfall. When sunshine is required, the top irradiation lamp 160 and the side irradiation lamp 170 are turned on to simulate solar radiation at different angles. Through the above coordinated control, the complex natural environment of high temperature, low temperature, high humidity, dryness, rain, snowfall, solar radiation, and different wind speed combinations can be accurately reproduced within the test chamber 131. Throughout the entire test cycle, key parameters such as the temperature of the inner and outer surfaces of the building envelope, heat flux density, air tightness, condensation, energy consumption, temperature and humidity uniformity, and fresh air efficiency of the indoor air conditioning system can be monitored in real time. This enables a true and direct verification of the overall performance of the building. At the same time, it is convenient to use the hanging mechanism 140 to drive the lifting of the building envelope 130 and the moving and adjusting of the test chamber 131 by the accompanying vehicle system 110.

[0034] This application also provides an overall performance environment simulation system, which includes the overall performance environment simulation cabin structure described above.
