Description

Technical Field

[0001] The present disclosure relates to the field of heating, ventilation and air conditioning, and in particular to an outdoor refrigeration pavilion device in summer. Background Art

[0002] The threat posed by heat waves to humans is increasing dramatically worldwide, especially in urban areas. Bus commuters and outdoor workers such as road workers and construction workers, who often need to work for long periods of time outdoors in high temperatures, are more likely to face the dual impacts of the urban heat island effect and heat waves. Therefore, ensuring the safety and comfort of the outdoor environment in cities is particularly important during heat waves. Although traditional outdoor shade pavilions can provide a certain degree of protection in outdoor environments, their actual safety benefits and thermal comfort are often unsatisfactory when dealing with heat waves. Natural cooling alone can no longer meet people's expectations for a comfortable outdoor environment. Although a concept of outdoor active cooling has emerged, traditional air-conditioning systems have many limitations in outdoor applications, and traditional air-conditioning has extremely demanding requirements on energy consumption. Therefore, pavilion devices based on evaporative cooling technology show their potential as an effective alternative. Summary of the invention

[0007] Furthermore, the conical top surface can be set to a shading angle as needed to adapt to the sunlight angle at different times and seasons.

[0022] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0023] Implementation Example 1

[0024] like Figure 1As shown, a summer outdoor cooling pavilion device includes: a base 1, a support column 2, a conical top surface 3, a spray device 4, a radiation plate heat exchanger 5, a water pipe 6, a water pump 7, a water replenishing device 8, a solar panel 9, a battery 10, a cable 11, and a passive radiation cooler 12. The base 1 is set on the ground and supports the conical top surface 3 through the support column 2. The spray device 4 is set above the outer side of the support column 2 and surrounds the support column 2, and is connected to the radiation plate heat exchanger 5 through the water pipe 6. The radiation plate heat exchanger 5 is set on the inner surface of the conical top surface 3 for cooling the inside of the pavilion, and is connected to the passive radiation cooler 12 through the water pipe 6. The passive radiation cooler 12 is set on the outer surface of the conical top surface 3, and is connected to the water pump 7 and the water replenishing device 8 through the water pipe 6. Its principle is mainly to dissipate heat to the outer space in the form of long-wave radiation, thereby reducing the temperature of the inner space of the pavilion. The solar panel 9 is set on the outer surface of the conical top surface 3 and is connected to the battery 10 through the cable 11. The battery 10 is arranged inside the conical top surface 3 and is connected to the water pump 7 through a cable 11 .

[0025] In some embodiments, the conical top surface 3 can be set to a shading angle according to the local summer sun altitude angle.

[0026] In some embodiments, the solar panel 9 is installed in the direct sunlight area of ​​the conical top surface 3 to improve the efficiency of solar power generation.

[0027] In some embodiments, the internal pipelines of the radiation plate heat exchanger 5 are composed of water pipes 6, and the internal design is a multi-layer distribution structure to improve the heat exchange efficiency.

[0028] In some embodiments, a forced ventilation device may be appropriately installed on the inner top of the pavilion to promote upward and downward air circulation, so as to enhance the cooling effect and further optimize the thermal comfort in the pavilion.

[0029] In some embodiments, the water pipe 6 is made of copper pipe to improve its heat exchange efficiency during the refrigeration process, and is used to connect the evaporative cooling device or the spray device 4, the water pump 7, the water replenishment device 8 and the radiation plate heat exchanger 5, and the exposed part in the middle is covered with insulation material.

[0030] In some embodiments, the base 1 is designed with a water collecting tank, and the gap between the water collecting tank and the base is filled with insulation material to collect cold water after cooling the spray device 4. This improves the cold storage capacity of the water collecting tank, thereby improving the overall use effect of the pavilion device while reducing its volume.

[0031] In some embodiments, the water pump 7 is disposed on the water pipe to provide power for the operation of the refrigerant water, and the energy required is provided by the battery.

[0032] In some embodiments, the water replenishment device 8 can be replaced by a water tank or directly by a water source near the pavilion to ensure that there is sufficient water in the device and reduce the impact of water loss during the process.

[0033] In some embodiments, the outer surface coating of the support column 2 uses a hydrophilic material to ensure that the water sprayed by the water spray device can form a stable water film on the surface of the support column to improve the heat exchange efficiency. In some embodiments, the coating uses a nano titanium dioxide (TiO2) coating, which can provide extremely high surface energy, making water molecules easy to diffuse and evaporate, which is conducive to forming a stable water film on the coating and promoting water evaporation to reduce the temperature of the water film and improve the cooling effect. In addition, nano TiO2 can also give the coating additional functions such as antibacterial and anti-pollution.

[0034] In some embodiments, the cable 11 is a DC cable to ensure safety and efficiency.

[0035] In some embodiments, the interior of the passive radiation cooler 12 is composed of a water pipe, and the passive radiation cooler 12 is coated with a radiation cooling coating, such as an aluminum coating suitable for high thermal radiation, a black body coating suitable for rapid cooling, and an aluminum oxide or aluminum nitride coating suitable for high temperature environments. The coating has high reflectivity and low thermal radiation capability. The passive radiation cooler 12 is installed on the north side of the top surface of the pavilion to ensure that it avoids direct sunlight, improves space radiation efficiency, and enhances the cooling effect.

[0036] Specifically, when the outside environment temperature rises in summer, the water in the pipe inside the radiation plate heat exchanger 5 begins to absorb heat. After absorbing heat, the temperature of the water rises and is transferred to the spray device 4 through the water pipe. The spray device 4 sprays the water in the water pipe in the form of water mist, forming a liquid film on the outer surface of the support column 2 while fully contacting with the dry and cold air outside. The hot water in the system is cooled by the principle of evaporation and heat absorption. The cooled cold water enters the water collection tank set inside the base 1, and the cold water is pumped into the passive radiation cooler 12 by the water pump on the water pipe connected to the water collection tank to provide power, and the excess heat in the cold water is dissipated to the outer space in the form of long-wave radiation, so that the cold water is further cooled, and then the cold water with a lower temperature enters the radiation plate heat exchanger 5, completing the heat cycle and forming a closed-loop system. In addition, the design of the support column 2 ensures that there is a good gas channel on its surface, so that the hot water coming out of the radiation plate heat exchanger 5 can be effectively cooled in the external environment, continuously providing a good cooling effect; an adjustable controller and a temperature monitoring device can also be set to continuously monitor the temperature changes in the pavilion, and automatically adjust the flow rate of the refrigerant water according to different conditions of the external environment to ensure that the system is in the best operating state.

[0037] In order to further optimize the implementation effect of the present disclosure, on the basis of the above content, some angles may be added or forced ventilation devices may be appropriately installed when installing the radiation plate heat exchanger to enhance the comfort of people in the pavilion.

[0038] The above is only a preferred embodiment of the present disclosure. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the concept of the present disclosure, which all belong to the protection scope of the present disclosure.
