Technical Field

[0001] The utility model relates to the technical field of controlled refrigeration in subways, in particular to a solar evaporative cooling air-conditioning system suitable for subway corridors. Background Art

[0002] Nowadays, more and more cities in my country are starting to build subways. Subway entrances and supermarkets are usually connected by corridors, which are exposed outdoors for pedestrians to pass through. In the hot summer, the temperature of outdoor subway corridors is high because they are exposed outdoors for a long time. Generally, there is no cooling equipment in subway corridors, and pedestrians feel unbearable heat when walking through them.

[0003] In addition, the outdoor subway corridors are not very airtight. If traditional mechanical refrigeration and air conditioning are used for cooling, the energy consumption will be high, the cold loss will be huge, the cooling effect will not be obvious, and the loss of refrigerants such as Freon will also cause environmental pollution. Summary of the invention

[0004] The purpose of this utility model is to solve the problem that outdoor subway corridors are exposed to the outdoors for a long time, the temperature is high, and pedestrians feel hot and unbearable when walking through them. When traditional mechanical refrigeration and air conditioning is applied in this place, the energy consumption is large, the cold loss is huge, the cooling effect is not obvious, and the loss of refrigerants such as Freon will also cause environmental pollution. A solar evaporative cooling air conditioning system suitable for subway corridors is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions.

[0007] An outdoor subway corridor, wherein the outdoor subway corridor is a gate arch structure, wherein a passage is formed inside the gate arch structure and a light-illuminating area is formed outside the gate arch structure, wherein one end of the passage forms an entrance and the other end is connected to a subway building;

[0008] A solar power generation panel, wherein the solar power generation panel is installed in the illumination area;

[0009] an air conditioning unit, the air conditioning unit being disposed inside the passage, between the subway building and the entrance, and communicating with an air inlet passing through the passage;

[0010] An inverter is assembled on the top inner wall of the channel and is communicatively connected with the air conditioning unit.

[0011] As a further improvement of the utility model, it also includes an assembly component, the door arch structure forms an inclined surface, along the inclined surface or the side of the solar panel, one is provided with a plurality of assembly buckles, and the other is provided with a plurality of assembly slots matching therewith.

[0012] As a further improvement of the present invention, from the inner wall of the channel to the center of the channel, the air conditioning unit includes a cold source component, an air duct, a fan and an air outlet connected in sequence.

[0013] As a further improvement of the present invention, the cold source component includes a packing structure arranged near the inner wall of the channel, and a water channel component formed along the packing structure, the water channel component provides a water source, and the water source is used to humidify the packing structure to form a cooling airflow.

[0014] As a further improvement of the utility model, the water circuit assembly includes a circulating water tank located below the packing structure, a circulating water pump close to the circulating water tank, and a water distributor located above the packing structure. The water distributor forms a pipeline with the circulating water pump and the circulating water tank through a water pipe.

[0015] As a further improvement of the present invention, the air conditioning unit also includes an assembly shell, the cross-section of the assembly shell is a rectangular cross-section with different lengths and widths, and the side length of the assembly shell along the length direction of the channel is greater than the side length toward the center of the channel.

[0016] As a further improvement of the present invention, the height of the assembly shell is L, the length of the assembly shell is greater than or equal to 4L, and the width of the assembly shell is greater than or equal to 2L.

[0017] As a further improvement of the present invention, there are at least two fans, the two fans are arranged side by side along the length direction of the channel, and the air outlets of the fans are arranged toward the center of the channel.

[0018] As a further improvement of the utility model, a filter net is also included. Perforations are provided at positions corresponding to the outdoor subway corridor and the air inlet. The filter net covers the perforations and is fixed to the outer periphery of the perforations.

[0019] As a further improvement of the present invention, there are a plurality of solar panels and air inlets, and the air inlets and solar panels are arranged in a matrix along the length of the channel, and the number of solar panels is greater than the number of air inlets.

[0020] The beneficial effects of the utility model are as follows:

[0021] 1) The solar evaporative cooling air conditioning system of the utility model is applied to outdoor subway corridors, and is particularly suitable for hot summers. In some subway entrance buildings in my country, subway entrances are usually designed with subway corridors (generally crossing roads) leading to shopping malls or other buildings. The subway corridor is not very closed and has a large flow of people. If traditional mechanical refrigeration and air conditioning are used, it is bound to cause serious loss of cold and excessive energy consumption of the unit. The use of the utility model evaporative cooling air conditioning can reduce energy consumption, filter outdoor air, and lower the temperature of the subway corridor, giving pedestrians in the corridor a fresh and cool feeling. Compared with traditional mechanical refrigeration and air conditioning, the application advantages of this air conditioning system are obvious.

[0022] 2) The evaporative cooling air conditioning system suitable for outdoor subway corridors in the utility model is used in combination with a solar power generation system. In the hot summer, subway corridors are exposed outdoors. After being exposed to the sun for a long time, the temperature rises, resulting in an increase in heat in the corridor. The use of solar panels can, on the one hand, use local materials, make full use of outdoor solar energy, and save energy. On the other hand, it can absorb the heat above the corridor and slow down the trend of heat increase in the corridor. This design is highly practical in places where it is inconvenient to use electricity in outdoor subway corridors.

[0023] 3) The evaporative cooling air conditioning system unit in the utility model is arranged in the subway corridor, and the air inlet is arranged outside the corridor. This design has many advantages compared with the unit exposed outside the subway corridor. First, when the unit fails, it is convenient to repair the air conditioning unit; second, after the unit has been in operation for a period of time, it is convenient to replace the filter and filler; third, the unit is prevented from being exposed to the sun, and the heat and moisture exchange occurs in the subway corridor to avoid the loss of cold. In summary, in the dry and hot northwest region of my country with relatively strong winds and sand, this design has obvious advantages and strong practicality.

[0024] 4) In the utility model, two fans are arranged side by side at the air outlet. This design cleverly combines the characteristics of subway corridors. Generally, the length of subway corridors is much greater than their width and height. By designing two fans side by side along the length of the subway corridor, the cross-sectional area of ​​the air inlet and outlet of the evaporative cooling air-conditioning unit can be increased, thereby increasing the air volume and the cooling amount entering the subway corridor. This design is clever and innovative. In the hot summer, the increase in air volume is bound to increase the comfort of pedestrians.

[0025] 5) This evaporative cooling air conditioning system unit adopts a rectangular shape, and the length of the unit is about 4 times the width of the unit; about 2 times the height of the unit. This design has two advantages in the application of subway corridors: on the one hand, it can increase the cross-sectional area of ​​the unit's air inlet and outlet, increase the unit's air volume, and thus increase the cooling capacity in the subway corridor; on the other hand, due to the small width of the unit (about one-fourth of the length; one-half of the height), the unit's footprint is reduced. This design increases the air volume and reduces the footprint without reducing the water storage capacity of the unit's circulating water tank, making it more reasonable and efficient to use in outdoor subway corridors.

[0031] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention. Example

[0032] This embodiment mainly introduces the core components.

[0033] See attached Figure 1-3 As shown, in this embodiment, the solar evaporative cooling air conditioning system suitable for subway corridors is used in an outdoor subway with an outdoor subway corridor, including:

[0034] An outdoor subway corridor 8, wherein the outdoor subway corridor 8 is a gate arch structure, wherein a passage is formed inside the gate arch structure and a light illumination area is formed outside the gate arch structure, wherein one end of the passage forms an entrance and the other end is connected to the subway building;

[0035] A solar power generation panel 7, wherein the solar power generation panel 7 is installed in the illumination area;

[0036] an air conditioning unit, the air conditioning unit being disposed inside the passage, between the subway building and the entrance, and communicating with an air inlet passing through the passage;

[0037] The inverter 9 is assembled on the top inner wall of the passage and is communicatively connected with the air conditioning unit.

[0038] In this embodiment, when in use, the air conditioning unit absorbs wind from the external air inlet, and then transfers it into the channel after cooling by the air conditioning unit to achieve cooling in the channel; when setting, the solar power generation panel 7 can be laid as much as possible in the area where the sun appears to form a shade shed to block sunlight in the channel, and then combined with the cooling of the air conditioning unit, multiple birds can be achieved at one stroke.

[0039] In this embodiment, in order to achieve stable assembly of the solar panel, an assembly component is also included. The door arch structure forms an inclined surface. Along the inclined surface or the side of the solar panel, one is provided with a plurality of assembly buckles (not shown in the figure), and the other is provided with a plurality of assembly slots (not shown in the figure) matching therewith. Specifically, a common connection buckle assembly in the prior art is selected, such as a slot body and a buckle assembled with the slot body through a protrusion. Of course, it can also be assembled by screws, etc.

[0040] In this embodiment, in order to better carry out the direction from the inner wall of the channel to the center of the channel, the air conditioning unit includes a cold source component 20, an air duct 3, a fan 5 and an air outlet 6 connected in sequence.

[0041] Furthermore, the cold source component 20 includes a packing structure 2 arranged near the inner wall of the channel, and a water channel component formed along the packing structure 2, the water channel component provides a water source, and the water source is used to humidify the packing structure 2 to form a cooling airflow. In this embodiment, the packing structure is specifically a honeycomb structure, and water enters and flows out through the gaps, and the flowing water is used to cool the air.

[0042] See attached Figure 1-2 As shown, the water circuit assembly includes a circulating water tank 4 located below the packing structure 2, a circulating water pump 12 near the circulating water tank 4, and a water distributor 11 located above the packing structure 2, and the water distributor 11 forms a pipeline with the circulating water pump 12 and the circulating water tank 4 through a water pipe 13. In this embodiment, a circulating pipeline is formed by the water circuit assembly, etc., so that water can continuously flow out and in, and then the low-temperature water is used to achieve cooling of the air in the packing structure 2.

[0043] In this embodiment, the air conditioning unit further comprises an assembly shell 15, the cross section of the assembly shell 15 is a rectangular cross section with different lengths and widths, and the side length of the assembly shell 15 along the length direction of the channel is greater than the side length in the direction toward the center of the channel. In this embodiment, the assembly shell is long along the length direction of the channel, wide along the horizontal cross-sectional direction of the channel, and high along the height direction of the channel.

[0044] Furthermore, if the height of the assembly shell 15 is L, the length of the assembly shell is greater than or equal to 4L, and the width of the assembly shell is greater than or equal to 2L. The assembly shell is constructed in a rectangular shape, and the length of the unit is approximately 4 times the width of the unit; and approximately 2 times the height of the unit. The assembly shell structure in this embodiment has two advantages when applied to subway corridors: on the one hand, it can increase the cross-sectional area of ​​the air inlet and outlet of the unit, increase the air volume of the unit, and thus increase the cooling capacity in the subway corridor; on the other hand, since the width of the unit is relatively small (approximately one-quarter of the length; one-half of the height), the unit footprint is reduced. This design increases the air volume and reduces the footprint without reducing the water storage capacity of the unit's circulating water tank, making it more reasonable and efficient to use in outdoor subway corridors.

[0045] In order to achieve better cooling, there are at least two fans 5, and the two fans 5 are arranged side by side along the length direction of the passage, and the air outlet 6 of the fan 5 is arranged toward the center of the passage. In this embodiment, two fans 5 are arranged side by side at the air outlet. This design cleverly combines the characteristics of the subway corridor, and the length of the subway corridor is generally much greater than the width and height. Designing two fans side by side along the length direction of the subway corridor can increase the cross-sectional area of ​​the air inlet and outlet of the evaporative cooling air-conditioning unit, thereby increasing the air outlet and increasing the amount of cold entering the subway corridor. This design is clever and innovative. In the hot summer, the increase in air outlet is bound to increase the comfort of pedestrians.

[0046] In order to improve the quality of air intake, a filter screen 14 is also included. The outdoor subway corridor 8 is provided with a perforation at a position corresponding to the air inlet 1. The filter screen 14 covers the perforation and is fixed to the periphery of the perforation. In this embodiment, the addition of the filter screen 14 blocks impurities and the like from the outside.

[0047] See attached Figure 3 As shown, there are multiple solar panels 7 and air inlets 1, and the air inlets 1 and solar panels 7 are arranged in a matrix along the length direction of the channel, and the number of solar panels 7 is greater than the number of air inlets 1. In this embodiment, the number of solar panels 7 is large, which can cover the illumination area with the largest area, achieving the effect of folding and fully utilizing solar energy. Example

[0048] In this embodiment, the specific use process is introduced.

[0049] The technical solution adopted by the utility model is a solar evaporative cooling air conditioning system suitable for subway corridors. The system is mainly composed of an evaporative cooling air conditioner (i.e., an air conditioning unit), a solar power generation panel 7, an inverter 9, and a battery 10, wherein the solar power generation panel 7 is arranged on the top of the subway corridor, and the evaporative cooling air conditioner, the inverter 9, and the battery 10 are arranged inside the subway corridor. Specifically, the inverter 9 and the battery 10 are arranged close to the side of the passage. Because the inverter and the battery have a certain weight, if they are arranged on the top, too many weighing carriers are required, and once they fall, safety accidents are likely to occur. If they are arranged on the side, they will fall directly from the side and are not likely to injure pedestrians. Furthermore, it can be arranged on the upper part of the air conditioning unit and assembled directly with the assembly shell of the air conditioning unit as the base. ( Figure 1 and 2 It is just a simple illustration to facilitate direct viewing of the two structures. In fact, the inverter 9 and the battery 10 should be arranged at the bottom.)

[0050] In this embodiment, the evaporative cooling air conditioner is provided with an air inlet 1, a filter 14, a packing structure 2, an air duct 3, a fan 5, and an air outlet 6 in sequence according to the flow direction of outdoor air. A water distributor 11 is provided above the packing structure 2, and a circulating water tank 4 is provided below the packing structure 2. The water distributor 11 and the circulating water tank 4 are connected through a circulating water pump 12 and a water pipe 13.

[0051] The technical solution adopted by the utility model is a solar evaporative cooling air conditioning system suitable for subway corridors. The solar evaporative cooling air conditioning system suitable for subway corridors is mainly composed of an evaporative cooling air conditioner, a solar power generation panel 7, an inverter 9, and a battery 10. The air conditioning system is combined with solar power generation to perform air conditioning on outdoor subway corridors in summer.

[0052] The operation mode in this embodiment is: in the hot summer, outdoor fresh air enters the air conditioner through the air inlet 1, and in the filling structure 2, the outdoor fresh air exchanges heat and moisture with the water sprayed by the water distributor 11, and the temperature of the outdoor fresh air is reduced. The cooled outdoor fresh air flows through the air duct 3, the fan 5, and the air outlet 6 respectively, and finally enters the inner side of the outdoor subway corridor 8 to cool down the pedestrians in the corridor.

[0053] (1) Outdoor fresh air working process in evaporative cooling system

[0054] Under the suction action of the fan 6, the outdoor fresh air enters the air conditioner through the air inlet 1, and exchanges heat and moisture with the water sprayed by the water distributor 11 in the filler structure 2. The temperature of the outdoor fresh air is reduced. The cooled outdoor fresh air flows through the air duct 3, the fan 5, and the air outlet 6 respectively, and finally enters the outdoor subway corridor 8.

[0055] (2) Working process of water system in evaporative cooling system

[0056] In the hot summer, the water in the circulating water tank 4 is pumped by the circulating water pump 12 and lifted to the water distributor 11 above the air conditioner through the water pipe 13. After being sprayed by the water distributor 11, the circulating water flows to the filler 2 below the water distributor 11 under the action of gravity. In the filler 2, the circulating water is fully in contact with the outdoor fresh air to exchange heat and moisture. After the heat and moisture exchange, the circulating water flows to the circulating water tank 4 at the bottom of the air conditioner, and the cycle continues.
