Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a solar absorption refrigeration device used in deserts. Background Art

[0002] A desert mainly refers to a barren area where the ground is completely covered with sand, plants are very scarce, rain is rare, and the air is dry. The desert has sufficient sunlight, and the temperature is usually high during the day and low at night.

[0003] Some scientific research or experiments need to be carried out in the desert. Due to the desert environment, living conditions are relatively poor, especially when the temperature is high during the day, the living place needs to be cooled. However, due to the limitations of conditions, conventional refrigeration and cooling equipment is difficult to use in the desert. Even if it can be used, the construction cost is high and it is difficult to be widely used.

[0004] Currently, there are also solar absorption refrigeration devices for deserts, for example, patent number CN201620213437.8, the patent name is a self-cleaning solar thermoacoustic refrigeration device for desert areas, which includes a second glass tube, the top of the second glass tube is connected to the resonance tube, and a second thermoacoustic stack is provided in the top of the second glass tube, and a first thermoacoustic stack is provided on the top of the resonance tube, and the first thermoacoustic stack is provided in the first glass tube with a closed top; a solar concentrator is fixed outside the second glass tube so that the lower part of the second thermoacoustic stack is located at the focus of the solar concentrator, and a hot water exchange water pipe is provided outside the top of the second glass tube. By using a concave mirror as a solar energy collection device, it can collect circulating cooling water, which can be used for plant dripping and daily life water, saving water resources; the whole device is divided into multiple sections by two thermoacoustic piles, and the thermoacoustic piles are in contact with the outside world, so that the fluid can directly pass through the inside of the thermoacoustic piles, thereby enhancing heat exchange, so that the cold end can achieve better thermoacoustic effect, and improve the utilization rate of cold energy, saving energy. Although the above device can use solar energy for cooling, due to the strong wind and sand in the desert, it is easy to cover the concave mirror used as a solar energy collection device, resulting in reduced work efficiency and extremely inconvenient cleaning.

[0032] like Figure 1-Figure 6 As shown, a solar absorption refrigeration device for deserts comprises a house 1, wherein an absorption refrigeration assembly 2, a cooling tower 3, a hot water tank 4 and a storage battery 5 are arranged in the house 1, the absorption refrigeration assembly 2 is connected to the hot water tank 4 and the cooling tower 3, and solar photovoltaic panels 6 and solar thermal collectors 7 are laid on both sides of the top of the house 1, respectively, the solar photovoltaic panels 6 are connected to the storage battery 5 through a photovoltaic controller 8, and the solar thermal collector 7 is connected to the absorption refrigeration assembly 2 and the hot water tank 4. In this embodiment, both sides of the top of the house 1 are arranged obliquely, and solar energy can be converted into electrical energy through the solar photovoltaic panels 6, and transported to the storage battery 5 through the photovoltaic controller 8 for storage, so as to be used in various electrical equipment, and water can be heated through the solar thermal collector 7, and hot water can be transported to the absorption refrigeration assembly 2, and the absorption refrigeration assembly 2 is driven by hot water for refrigeration, and cold air or cold water is transported to the carrier to realize the refrigeration function, and the used hot water is transported to the hot water tank 4, and the hot water tank 4 is connected to the solar thermal collector 7, thereby forming a circulation production of hot water;

[0033] A first cleaning component 9 is provided on the top of the roof 1 and on one side close to the solar photovoltaic panel 6, and a second cleaning component 10 is provided on the top of the roof 1 and on one side close to the solar thermal collector 7. Both the first cleaning component 9 and the second cleaning component 10 are installed on a driving mechanism 11, and the driving mechanism 11 is installed on the top of the roof 1. The driving mechanism 11 can drive the first cleaning component 9 to move along the surface of the solar photovoltaic panel 6, and drive the second cleaning component 10 to move along the surface of the solar thermal collector 7, thereby cleaning the sand and dust accumulated on the surface of the solar photovoltaic panel 6 and the surface of the solar thermal collector 7, thereby ensuring the working efficiency of the solar photovoltaic panel 6 and the solar thermal collector 7.

[0034] like Figure 5 As shown, the absorption refrigeration assembly 2 includes a generator 201, a condenser 202, an evaporator 203 and an absorber 204, the generator 201 is connected to the solar collector 7, the hot water tank 4, the condenser 202 and the absorber 204, the condenser 202 is connected to the cooling tower 3 and the evaporator 203, the evaporator 203 is connected to the load 12 and the absorber 204, the load 12 is mainly cold air or cold water, and the absorber 204 is connected to the generator 201 and the cooling tower 3;

[0035] Specifically, in this embodiment, the generator 201 contains a lithium bromide solution, and the hot water heated by the solar collector 7 flows into the generator 201 to heat the lithium bromide solution, so that the water in the lithium bromide solution evaporates into refrigerant steam and enters the condenser 202. The refrigerant steam undergoes a phase change and liquefaction in the condenser 202, releasing heat. The cooling water of the cooling tower 3 is connected to the condenser 202 to cool the condenser 202. The liquefied refrigerant steam passes through the throttle valve and enters the evaporator 203 to expand and evaporate, and then changes phase to gas again, and absorbs the heat of the cooled space, thereby cooling the cold air or cold water. The temperature is lowered and refrigerated, and then the gaseous refrigerant vapor enters the absorber 204. At the same time, the cooling water of the cooling tower 3 is also connected to the absorber 204 to cool the absorber 204. After the water in the lithium bromide solution in the generator 201 evaporates, the lithium bromide solution gradually concentrates from a dilute solution to a high-concentration lithium bromide solution, and the concentrated solution is transported to the absorber 204 through a throttle valve. In the absorber 204, the gaseous refrigerant vapor is absorbed by the concentrated high-concentration lithium bromide solution, and the high-concentration lithium bromide solution becomes a dilute solution again and is transported back to the lithium bromide generator 201, thereby forming a cycle.

[0036] like Figure 1-Figure 4As shown, the first cleaning component 9 and the second cleaning component 10 both include a mounting block 901, which is mounted on the driving mechanism 11, and a cleaning plate 902 is mounted on one end of the mounting block 901 facing the solar photovoltaic panel 6 and the solar thermal collector 7, and the cleaning plate 902 is movably mounted in a mounting hole 903 set on the mounting block 901, and a spring 904 is provided between the cleaning plate 902 and the inner wall of the mounting hole 903, and a side of the cleaning plate 902 away from the spring 904 is densely covered with cleaning hairs 905, and the sand and dust accumulated on the solar photovoltaic panel 6 and the solar thermal collector 7 can be cleaned by the cleaning hairs 905, and the elasticity of the cleaning plate 902 is increased by providing the spring 904, so that the cleaning hairs 905 can be closely attached to the solar photovoltaic panel 6 and the solar thermal collector 7 no matter how worn they are.

[0037] like Figure 1-Figure 3 As shown, the driving mechanism 11 includes a driving frame 1101 located on both sides of the top of the roof 1, and a driving plate 1102 is movably installed on the driving frame 1101, and the mounting block 901 is installed on the driving plate 1102. A driving screw 1103 is threadedly penetrated on the driving plate 1102. Specifically, a screw nut is installed on the driving plate 1102, and the screw nut is threadedly connected with the driving screw 1103. The driving screws 1103 are arranged opposite to each other and are rotatably installed on the first fixing seat 1104, and the first fixing seat 1104 is installed on the top of the roof 1;

[0038] The two driving screws 1103 shown are both equipped with bevel gears 1105 at one end close to the top of the roof 1, and a bevel gear plate 1106 is meshed between the two bevel gears 1105. The bevel gear plate 1106 is installed on the output shaft of the driving motor 1107, and the driving motor 1107 is installed on the support frame 1108. The support frame 1108 is installed on the top of the roof 1. The driving motor 1107 can drive the bevel gear plate 1106 to rotate, and the bevel gear plate 1106 drives the two bevel gears 1105 to rotate synchronously through gear meshing. The bevel gear 1105 drives the driving screw 1103 to rotate, and the driving screw 1103 drives the driving plate 1102 to move along the driving frame 1101 during the rotation. Since the first cleaning component 9 and the second cleaning component 10 are installed on the driving plate 1102, the first cleaning component 9 and the second cleaning component 10 are driven to clean the dust on the surface of the solar photovoltaic panel 6 and the solar thermal collector 7.

[0039] like Figure 1-Figure 2As shown, the driving frame 1101 includes two guide rods 11011 arranged opposite to each other, and the two guide rods 11011 are respectively arranged at the two ends of the roof 1, and the two guide rods 11011 slide through the driving plate 1102. Specifically, a guide sleeve is installed on the driving plate 1102, and the guide rod 11011 slides through the guide sleeve. The driving screw 1103 is located between the two guide rods 11011, and both ends of the guide rod 11011 are installed on the second fixed seat 11012, and the second fixed seat 11012 is installed on the top of the roof 1, and the driving plate 1102 is moved and guided by the guide rod 11011.

[0040] like Figure 1 and Figure 4 As shown, the mounting block 901 is of a T-shaped structure, and a T-shaped slot matching the mounting block 901 is provided on the driving plate 1102. The mounting block 901 is slidably installed in the T-shaped slot, and both ends are fixed by end plates 1109. By setting the T-shaped slot and the mounting block 901 of the T-shaped structure, the installation is convenient.

[0041] For ease of understanding, the working process of this embodiment is given below:

[0042] like Figure 1-Figure 6 As shown, the refrigeration process:

[0043] The generator 201 contains a lithium bromide solution. The hot water heated by the solar collector 7 flows into the generator 201, heats the lithium bromide solution, and evaporates the water in the lithium bromide solution into refrigerant vapor, which then enters the condenser 202. The refrigerant vapor undergoes a phase change and liquefies in the condenser 202, releasing heat. The cooling water of the cooling tower 3 is connected to the condenser 202, and cools the condenser 202. The liquefied refrigerant vapor passes through the throttle valve and enters the evaporator 203 to expand and evaporate, and then changes phase to a gaseous state again, and absorbs the heat of the cooled space, thereby cooling the cold air or cold water. After cooling, the gaseous refrigerant vapor enters the absorber 204. At the same time, the cooling water of the cooling tower 3 is also connected to the absorber 204 to cool the absorber 204. After the water in the lithium bromide solution in the generator 201 evaporates, the lithium bromide solution gradually concentrates from a dilute solution to a high-concentration lithium bromide solution, and the concentrated solution is transported to the absorber 204 through a throttle valve. In the absorber 204, the gaseous refrigerant vapor is absorbed by the concentrated high-concentration lithium bromide solution, and the high-concentration lithium bromide solution becomes a dilute solution again and is transported to the lithium bromide generator 201 again, thereby forming a cycle;

[0044] Cleaning process:

[0045] The output shaft of the driving motor 1107 rotates, and drives the bevel gear plate 1106 to rotate synchronously. The bevel gear plate 1106 drives the bevel gear 1105 to rotate synchronously through gear meshing. During the rotation of the bevel gear 1105, the driving screw 1103 is driven to rotate synchronously. During the rotation of the driving screw 1103, the driving plate 1102 is driven to move axially along the guide rod 11011. Since the first cleaning component 9 and the second cleaning component 10 are respectively installed on the driving plate 1102, the first cleaning component 9 and the second cleaning component 10 are driven to move on the surface of the solar photovoltaic panel 6 and the solar collector 7, and the dust attached to the surface is cleaned by the cleaning bristles 905.

[0046] In summary, the utility model provides a solar absorption refrigeration device for use in the desert, which can use solar energy for refrigeration and power generation in the desert, and can conveniently clean the sand and dust accumulated on the solar photovoltaic panels and solar thermal collectors, with high refrigeration and power generation efficiency.
