In this embodiment, the first temperature control air conditioner 131 is arranged on the side inner wall of the first incubation room 110 and close to the upper inner wall of the first incubation room 110, thereby making the temperature control effect of the first temperature control air conditioner 131 on the first incubation room 110 better, reducing energy consumption, and reducing test cost. In addition, the first temperature control air conditioner 131 is arranged opposite to the first water tank 120, thereby avoiding the first water tank 120 from hindering the maintenance work of the first temperature control air conditioner 131. The electric energy consumed by the first temperature control air conditioner 131 is set as W1.
[0047] In this embodiment, the radiation refrigeration module 140 is arranged at the top of the first incubation room 110, and the two ends of the radiation refrigeration module 140 are respectively communicated with the first water tank 120 through pipelines, thereby making the liquid in the first water tank 120 circulate and flow between the first water tank 120 and the radiation refrigeration module 140. Part of the pipeline is arranged in the first incubation room 110, and the other part of the pipeline is arranged outside the first incubation room 110, and the outer wall of the pipeline arranged outside the first incubation room 110 is provided with a temperature insulation layer, thereby ensuring that the temperature in the first incubation room 110 is balanced as much as possible by the radiation refrigeration module 140 and the first temperature control air conditioner 131. The temperature insulation layer can avoid heat loss from the pipeline wall surface.
[0048] The radiation refrigeration module 140 includes a bearing bracket 141, a reflector 142, an anti-convection frame 143, and a plurality of cooling pipelines 144. The bearing bracket 141 includes a plurality of bearing rods arranged in sequence with gaps between adjacent bearing rods, thereby reducing the manufacturing cost and increasing the bearing area of the bearing bracket 141.
[0049] The reflector 142 is arranged on the upper surface of the bearing bracket 141 facing away from the first incubation room 110. The reflector 142 has wave crests and wave troughs, and the arrangement direction of the wave crests and wave troughs is consistent with the arrangement direction of the bearing rods. Further, a plurality of cooling pipelines 144 are arranged between adjacent two wave crests of the reflector 142. The surface of the cooling pipeline 144 is provided with a radiation refrigeration material for radiation refrigeration of the liquid in the cooling pipeline 144.
[0050] Further, the two ends of the plurality of cooling pipes 144 are respectively provided with an inlet pipe 145 and an outlet pipe 146, one end of the outlet pipe 146 is in communication with the first water tank 120, the inlet pipe 145 and the outlet pipe 146 are in communication with the other ends which are opposite to each other and the first water tank 120, and one end of the plurality of cooling pipes 144 is in communication with the inlet pipe 145 and the other end of the plurality of cooling pipes 144 is in communication with the outlet pipe 146, so as to ensure that the liquid flows into the plurality of cooling pipes 144, passes through the radiation refrigeration, and then flows into the first water tank 120 from the outlet pipe 146.
[0051] In order to detect the change of water temperature and know the water temperature in real time, and avoid the equipment damage caused by the experiment completion, in the embodiment, the water temperature sensor 147 is arranged at the other end of the inlet pipe 145 and the outlet pipe 146, so as to detect the change of water temperature in real time, ensure that the liquid reaches the specified temperature after being cooled, and confirm the normal operation of the radiation refrigeration module 140.
[0052] The anti-convection frame 143 is arranged along the bearing support 141, and then the anti-convection space is formed, so as to ensure that the bearing support 141 is in a sealed state except the space directly above, further, the sealing glue is filled between the components of the anti-convection frame 143, the PE film 148 is arranged in the space directly above the anti-convection frame 143, the PE film 148 is connected with the anti-convection frame 143, and the waterproof seal is arranged at the connection, so as to ensure the sealing property and waterproof property of the radiation refrigeration module 140.
[0053] The outer surface of the anti-convection frame 143 is preferably made of white non-heat-absorbing material, so as to avoid that the anti-convection frame 143 absorbs too much light heat, and then affects the refrigeration effect of the radiation refrigeration module 140.
[0054] In the embodiment, please refer to Figures 1-12 The second measurement assembly 200 includes a second heat preservation room 210, a second water tank 220, a second temperature control module 230 and a radiation refrigeration module 140, the outer wall of the second heat preservation room 210 is provided with a temperature insulation material, so as to ensure that the temperature in the second heat preservation room 210 is constant during the experiment, further, the second water tank 220 and the second temperature control module 230 are arranged in the second heat preservation room 210, the second water tank 220 contains liquid, and the liquid can be tap water, deionized pure water, cooling liquid or non-conductive liquid, etc., in the embodiment, the second water tank 220 contains tap water, so as to reduce the experimental cost.
[0055] The second water tank 220 can be arranged at any position in the second heat preservation room, in the embodiment, the second water tank 220 is arranged close to the inner wall of the side of the second heat preservation room 210, so as to provide enough installation space for the remaining experimental components.
[0056] The second temperature control module 230 comprises a second temperature control air conditioner 231 and a second air conditioner electric energy meter 232, and the second temperature control air conditioner 231 and the second air conditioner electric energy meter 232 are electrically connected to each other. The second electric energy meter is used to record and display the electric energy consumed by the second temperature control air conditioner 231 during operation. The second temperature control air conditioner 231 can be arranged at any position in the second heat preservation room 210. In the embodiment, the second temperature control air conditioner 231 is arranged on the inner wall of the side of the second heat preservation room 210 and close to the upper inner wall of the second heat preservation room 210, so that the temperature control effect of the second temperature control air conditioner 231 on the second heat preservation room 210 is better, thereby reducing the energy consumption and the test cost. In addition, the second temperature control air conditioner 231 is arranged opposite to the second water tank 220, thereby avoiding the obstruction of the second water tank 220 to the maintenance work during the maintenance of the second temperature control air conditioner 231. The electric energy consumed by the second temperature control air conditioner 231 is denoted as W2.
[0057] In the embodiment, the contrast module 240 is arranged on the top of the second heat preservation room 210, and the two ends of the contrast module 240 are respectively communicated with the second water tank 220 through pipelines, so that the liquid in the second water tank 220 circulates and flows between the second water tank 220 and the contrast module 240. A part of the pipeline is arranged in the second heat preservation room 210, and the other part of the pipeline is arranged outside the second heat preservation room 210, and the outer wall of the pipeline arranged outside the second heat preservation room 210 is provided with a temperature insulation layer, so as to ensure that the temperature of the liquid is stable and will not cause damage to the workers.
[0058] The contrast module 240 comprises a contrast bearing support 241, a contrast mirror 242, a contrast anti-convection frame 243 and a plurality of contrast cooling pipelines 244. The contrast bearing support comprises a plurality of contrast bearing rods 241a. The two ends of the plurality of contrast cooling pipelines 244 are respectively provided with a contrast liquid inlet pipeline 245 and a contrast liquid outlet pipeline 246. The upper end of the contrast anti-convection frame 243 is provided with a contrast PE film 248. The contrast liquid inlet pipeline 245 and the contrast liquid outlet pipeline 246 are respectively provided with a contrast water temperature sensor 247. The contrast bearing support 241, the contrast mirror 242, the contrast anti-convection frame 243 and the plurality of contrast cooling pipelines 244 in the contrast module 240 are respectively identical in structure to the bearing support 141, the mirror 142, the anti-convection frame 143 and the cooling pipeline 144 of the radiation refrigeration module 140. The only difference is that the contrast cooling pipeline 244 in the contrast module 240 is not provided with a radiation cooling coating, and therefore will not be described in detail.
[0059] The first measuring assembly 100 further comprises a first infusion pump 170 and a first liquid delivery pump 180, and the second measuring assembly 200 further comprises a second infusion pump 270 and a second liquid delivery pump 280, the first infusion pump 170 and the first liquid delivery pump 180 are oppositely arranged at two ends of the first water tank 120, and the second infusion pump 270 and the second liquid delivery pump 280 are oppositely arranged at two ends of the second water tank 220, thereby providing power for liquid circulation, wherein one end of the first liquid delivery pump 180 is provided with a first liquid delivery pump electric energy meter 181, and one end of the second liquid delivery pump 280 is provided with a second liquid delivery pump electric energy meter 281.
[0060] When the test is performed, the liquid in the first water tank 120 and the second water tank 220 flows through the radiation refrigeration module 140 and the control module 240 respectively through the pipeline, and then enters the first incubation room 110 and the second incubation room 210 respectively, thereby cooling the first incubation room 110 and the second incubation room 210, and the first temperature control air conditioner 131 and the second temperature control air conditioner 231 respectively perform auxiliary temperature control, so that the temperature in the first incubation room 110 and the second incubation room 210 is constant and consistent, finally, the readings of the first air conditioner electric energy meter 132 and the second air conditioner electric energy meter 232 are read, and the energy consumed by the first temperature control air conditioner 131 to maintain the temperature is W1, and the energy consumed by the second temperature control air conditioner 231 is W2, due to the radiation refrigeration module 140, the temperature of the liquid flowing through the first incubation room 110 is low, so the cooling effect is consumed, therefore the energy consumed by the first temperature control air conditioner 131 to maintain the first incubation room 110 is less than that of the second temperature control air conditioner 231, and the reason for the difference in energy consumption is that the liquid flowing through the radiation refrigeration module 140 is cooled by radiation refrigeration, and the temperature of the liquid flowing through the control module 240 is different, and the energy consumed by the radiation refrigeration module 140 to cool the liquid in it is consistent with the difference between the energy consumed by the first temperature control air conditioner 131 and the second temperature control air conditioner 231, here, the energy consumed by the radiation refrigeration module 140 to cool the liquid is W 制冷, W 制冷 = W2-W1.
[0061] The temperature in the first incubation room 110 and the second incubation room 210 is consistent with or has a small difference with the temperature of the liquid that has not been cooled.
[0062] The water quantity in the first water tank 120 and the second water tank 220 is consistent.
[0063] The heating power of the first heating element 150 and the second heating element 250 is consistent.
[0064] Supposing that the time of the test is t, the area of the refrigeration coating in the radiation refrigeration module 140 is S, and the radiation refrigeration power P, then according to the power calculation formula, the radiation refrigeration power P = W 制冷 t -1 S -1= (W2 - W1) t -1 S -1 .
[0065] Further, when the second holding room 210 is maintained, the energy consumed by the second temperature control air conditioner 231 is the total amount of energy consumed to reduce the second holding room 210 to the specified temperature, and the radiation cooling efficiency η = W 制冷 / W2, and the radiation cooling efficiency η is further obtained.
[0066] It should be understood that the liquid consumes part of the energy when flowing through the pipeline, and is affected by external environmental temperature and other related factors, thereby dissipating part of the energy. If the liquid is lower during the test, the energy consumed during the radiation cooling is lower, thereby resulting in a lower difference in the energy consumed by the first temperature control air conditioner 131 and the second temperature control air conditioner 231, and the above formula P = W 制冷 t -1 S -1 = (W2 - W1) t -1 S -1 It can be seen that the energy lost by the liquid due to external influences has a greater impact on the final measurement result.
[0067] Therefore, in order to make the measurement result more accurate, in some embodiments, the first measurement assembly 100 further includes a first heating element 150 and a first heating electric energy meter 160 electrically connected to each other, the first heating element 150 is arranged in the holding room, and the two ends of the heating element are respectively communicated with the first water tank 120 and the radiation cooling module 140 through the pipeline.
[0068] The second measurement assembly 200 further includes a second heating element 250 and a second heating electric energy meter 260 electrically connected to each other, the second heating element 250 is arranged in the holding room, and the two ends of the heating element are respectively communicated with the second water tank 220 and the control module 240 through the pipeline.
[0069] The first heating element 150 and the second heating element 250 respectively heat the liquid flowing out of the first water tank 120 and the second water tank 220, and heat to the same temperature, so that the energy consumed during the radiation cooling is larger, thereby making the difference in the energy consumed by the first temperature control air conditioner 131 and the second temperature control air conditioner 231 larger, thereby making the result smaller when the measurement result is affected by environmental temperature, heat consumed when flowing through the pipeline and other factors, thereby ensuring the accuracy of the measurement result.
[0070] Among them, since the heating temperature of the first heating element 150 and the second heating element 250 is consistent, the temperature of the liquid is consistent, wherein the data measured by the first heating electric energy meter 160 and the second heating electric energy meter 260 are W3 and W4 respectively, therefore W3-W4=0, and the radiation cooling power P = W 制冷 t-1 S -1 = (W2-W1)t -1 S -1 .
[0071] In some embodiments, a first flow meter 190 is arranged on the pipeline between the first liquid feeding pump 180 and the radiant cooling module 140, and a second flow meter 290 is arranged on the pipeline between the second liquid feeding pump 280 and the control module 240. Specifically, the first flow meter 190 is arranged near the liquid inlet end of the radiant cooling module 140, and the second flow meter 290 is arranged near the liquid inlet end of the control module 240, so that the operator can confirm the consistency of the flow of the circulating liquid in the pipelines of the first measuring assembly 100 and the second measuring assembly 200 at any time through the first flow meter 190 and the second flow meter 290, thereby ensuring the accuracy of the measurement results.
[0072] In some embodiments, referring to FIGS. 1, 2 and 3, Figure 1 and Figure 6 the top of the first water tank 120 is in communication with the radiant cooling module 140 through a pipeline, the first heating element 150 is connected to the first water tank 120 near the bottom end, the top of the second water tank 220 is in communication with the control module 240 through a pipeline, and the second heating element 250 is connected to the second water tank 220 near the bottom end, so that the liquid in the first water tank 120 and the second water tank 220 is circulated and flows through, avoiding the influence of the residual liquid in the first water tank 120 and the second water tank 220 on the temperature of the circulating liquid, thereby avoiding the deviation of the measurement results.
[0073] In addition, the liquid can flow from the first water tank 120 and the second water tank 220 to the first heating element 150 and the second heating element 250 under the action of gravity, thereby reducing the energy consumption during the test and saving costs.
[0074] In some embodiments, referring to FIGS. 1, 2 and 3, Figures 7-12The second measuring assembly 200 further comprises a connecting pipeline 400. In actual application of the system, the radiation cooling module 140 is large in area and is heated under sunlight. The connecting pipeline 600 can avoid the pipeline from being heated in the second measuring assembly 200, so that the environmental heat is avoided from being introduced, and the result is more reasonable and accurate. The connecting pipeline 400 is in communication with the pipelines at two ends of the control module 240. One end of the connecting pipeline 400 in communication with the liquid inlet end of the control module 240 is provided with a connecting on-off valve 410 for controlling the liquid to pass through the control module 240. The pipeline at the liquid inlet end of the control module 240 is further provided with a third water flow on-off valve 420 for controlling the liquid to enter the control module 240.

[0077] To sum up, in the embodiment of the application, the first holding room 110 and the second holding room 210 are water-cooled and temperature-controlled by the liquid in the pipeline, wherein the liquid after the radiation refrigeration has a lower temperature and a better water-cooling effect. In addition, the temperature in the first holding room 110 and the second holding room 210 is maintained constant and consistent by the first temperature control air conditioner 131 and the second temperature control air conditioner 231, so that the difference in the power consumed by the first temperature control air conditioner 131 and the second temperature control air conditioner 231 is the heat energy consumed by the radiation of the liquid after the radiation refrigeration. Therefore, the cooling efficiency of the radiation water-cooling system can be obtained by the efficiency calculation formula, and the cooling efficiency of the radiation refrigeration system can be obtained, so that the result of the radiation refrigeration system is data-based and accurate.
