Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an ultra-high temperature heat-resistant air conditioner. Background Art

[0002] As industrial production continues to develop towards high precision and high productivity, the ambient temperature in special operating environments such as the areas around blast furnaces in the metallurgical industry, casting stations in foundries, and melting furnaces in glass processing has been rising year by year due to the continuous heat release of equipment, highly enclosed spaces, and limited heat dissipation conditions. Therefore, air-conditioning equipment is required to have strict technical requirements that far exceed those in conventional environments. Specifically, air conditioners must have excellent heat resistance, and their external components must maintain stable operation under the dual effects of their own heat generation and high ambient temperature to avoid accelerated aging or functional failure due to insufficient heat resistance of materials, ensuring continuous and reliable environmental protection for industrial production.

[0003] At present, air-conditioning technology suitable for conventional environments has exposed significant technical limitations under ultra-high temperature conditions. In terms of heat exchange technology, traditional air conditioners mostly adopt a single-group heat exchanger design, which has a limited heat exchange area and a lack of targeted optimization of the heat dissipation structure. Hot air flow is prone to form eddies and accumulation in the machine body, resulting in a sharp drop in heat exchange efficiency as the ambient temperature rises, making it difficult to meet the heat dissipation needs in ultra-high temperature environments. At the same time, the heat dissipation method of existing air conditioners is single, mainly relying on natural air convection. In a dry and hot environment, the heat dissipation capacity of the air is greatly attenuated, and the heat generated by the heat exchanger cannot be quickly discharged, thereby restricting the continuous operation of the refrigeration system. Although some air conditioners It has a simple spray cooling function, but can only rely on an external water supply system, which not only increases operating costs, but also has application limitations in industrial scenarios with water shortages. In terms of refrigeration power system technology, traditional air conditioners generally adopt a single compressor configuration, and its rated operating parameters are difficult to adapt to the high load requirements in ultra-high temperature environments. When the ambient temperature exceeds the design threshold, the compressor needs to be in full-power operation for a long time, and the compression ratio increases significantly, resulting in excessively high exhaust temperature, which will not only accelerate the aging of the motor winding insulation, but may also cause increased wear due to overheating of mechanical components, seriously shortening the service life of the compressor and making it impossible to guarantee the continuity of industrial production.

[0015] (3) Beneficial effects

[0018] 2. By setting up dual compressors, the air conditioner can flexibly adjust the operating load according to the ambient temperature to meet different cooling needs. While ensuring the cooling effect, it is beneficial to save energy. When the ambient temperature is at an ultra-high temperature, the two compressors are controlled to run at the same time, thereby reducing the operating power of the compressor and avoiding overload of the compressor, which causes the temperature to be too high and thus affects the service life. At the same time, the breathable plate enhances air circulation and further improves the heat dissipation effect. The first drying filter and the second drying filter can effectively remove moisture and impurities in the refrigerant, avoiding moisture freezing and clogging the pipes during the refrigerant circulation process, and impurities causing wear on components such as the compressor, thereby protecting the refrigerant system and extending the service life of the equipment.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 2 、 Figure 5 、 Figure 6 and Figure 7, which is the first embodiment of the present invention, provides an ultra-high temperature heat-resistant air conditioner, including a base plate 1, an external machine frame 2 is provided on the surface of the base plate 1, a first heat exchanger 5 and a second heat exchanger 6 are provided inside the external machine frame, and two vents 3 are provided on the top of the external machine frame 2, and a fixing frame 32 is provided at the lower end of the two vents 3, one side of the fixing frame 32 is fixedly connected to the middle partition 7, the lower end of the middle partition 7 is fixedly connected to the surface of the base plate 1, and a temperature sensor 21 is installed on the surface of the middle partition 7, and the fixing frame 32 is fixedly connected to the middle partition 7. A water guide plate 33 is provided on the surface, and a collecting box 26 is provided at the lower end of the water guide plate 33. The inner wall of the collecting box 26 is fixedly connected with an inclined panel 27. A filter groove 28 is provided on the surface of the inclined panel 27. The lower end of the filter groove 28 is provided with a first filter layer 29, a second filter layer 30 and a third filter layer 31. One side of the third filter layer 31 is connected to a water storage cylinder 22. A water pump 23 is installed inside the water storage cylinder 22. The output end of the water pump 23 is fixedly connected to a water pipe 24, and the top of the water pipe 24 is fixedly connected to a spray pipe 25.

[0031] Specifically, the first filter layer 29 is filled with anthracite, the second filter layer 30 is filled with quartz sand, the second filter layer 30 is filled with activated carbon, the angle between the fixed frame 32 and the horizontal line is 15 degrees, the number of water guide plates 33 is set to multiple groups, and multiple groups of water guide plates 33 are stacked on each other, and a cooling fan 20 is provided above the fixed frame 32, and the cooling fan 20 is installed on the top of the inner wall of the external frame 2.

[0032] Furthermore, when the ultra-high temperature heat-resistant air conditioner is running, the cooling fan 20 installed on the top of the inner wall of the outer frame 2 is started. Since the fixed frame 32 is at an angle of 15 degrees to the horizontal line, under the action of the cooling fan 20, the hot air flow can be discharged along the gaps between the multiple stacked guide plates. The middle partition 7 separates the internal space of the outer frame 2, so that the spaces where the first heat exchanger 5 and the second heat exchanger 6 are located are independent of each other, avoiding mutual interference of the air flows around the two heat exchangers, and enhancing the heat exchange efficiency between the first heat exchanger 5 and the second heat exchanger 6 and the air. At the same time, on rainy days, rainwater from the outside will be collected by multiple groups of stacked water guide plates 33. The water guide plates 33 guide the water to the fixed frame 32, and the water flows into the collection box 26 along the fixed frame 32. The inclined panel 27 in the collection box 26 plays a guiding role, introducing the water into the filter tank 28. When the water enters the first filter layer 29, the anthracite in the first filter layer 29 reacts with the water. The organic matter and larger suspended solids in the water are filtered and removed, and then the water flows to the second filter layer 30, where the quartz sand in the second filter layer 30 intercepts the fine particles in the water. Then, after the water enters the third filter layer 31, the activated carbon in the third filter layer 31 absorbs the odor and residual impurities in the water to complete the water purification. The purified water enters the water storage cylinder 22. When the temperature sensor 21 detects that the internal temperature of the external frame 2 is too high, the water pump 23 in the water storage cylinder 22 is started through the controller 34, and the purified water is transported to the spray pipe 25 through the water pipe 24. The spray pipe 25 sprays the water on the surface of the first heat exchanger 5 and the second heat exchanger 6 to assist the heat exchanger in dissipating heat. At the same time, the cleaned water can also flow into the collection box 26 to complete the cycle.

[0033] Example 2

[0034] Reference Figure 1 、 Figure 3 and Figure 4 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. A first refrigerant pipe 8 and a second refrigerant pipe 9 are provided inside the external frame 2. One end of the first refrigerant pipe 8 is fixedly connected to the first compressor 10. The first compressor 10 and one end of the second refrigerant pipe 9 are fixedly connected to the second compressor 11. The output ends of the second compressor 11 and the first compressor 10 are both fixedly connected to a flow pipe 12. One end of the two flow pipes 12 is connected to a shunt pipe 13. The two shunt pipes 13 are respectively connected to the first heat exchanger 5 and the second heat exchanger 6.

[0035] Specifically, the output ports of the first heat exchanger 5 and the second heat exchanger 6 are respectively connected to the first outflow pipe 14 and the second outflow pipe 15, one end of the first outflow pipe 14 and the second outflow pipe 15 are respectively connected to the first drying filter 16 and the second drying filter 17, the output ends of the first drying filter 16 and the second drying filter 17 are fixedly connected to the delivery pipe 18, one end of the two delivery pipes 18 is connected to the converging pipe 19, and the outside of the first heat exchanger 5 and the second heat exchanger 6 is provided with a breathable plate 4, which is fixed to the surface of the external frame 2 by bolts. A controller 34 is installed inside the external frame 2, and the controller 34 is electrically connected to the first heat exchanger 5, the second heat exchanger 6, the first drying filter 16, the second drying filter 17, the water pump 23 and the temperature sensor 21.

[0036] Furthermore, when cooling is required, the controller 34 controls the first compressor 10 and the second compressor 11 to start according to the temperature signal. The refrigerant generated by the first compressor 10 is transported to the corresponding inlet pipe through the first refrigerant pipe 8, and then enters the first heat exchanger 5 through the diverter pipe 13. The refrigerant generated by the second compressor 11 is transported to the corresponding inlet pipe through the second refrigerant pipe 9, and then enters the second heat exchanger 6 through the diverter pipe 13. After the refrigerant exchanges heat in the first heat exchanger 5 and the second heat exchanger 6, it flows out through the first outflow pipe 14 and the second outflow pipe 15 respectively, and enters the first drying filter 16 and the second drying filter 17. The first drying filter 16 and the second drying filter 17 remove moisture and impurities in the refrigerant. The purified refrigerant is merged into the confluence pipe 19 through the transport pipe 18, completing the refrigerant circulation. (The models of the first compressor 10 and the second compressor 11 are both YW132K1 - 100, used to compress the low-temperature, low-pressure gaseous refrigerant from the evaporator into a high-temperature, high-pressure gaseous refrigerant. The first filter dryer 16 and the second filter dryer 17 are model DML083S and are used to remove moisture and impurities from the refrigerant. In addition, the air permeable plate 4 fixed to the surface of the outer frame 2 by bolts enhances air circulation inside and outside the outer frame 2, further assisting the heat dissipation of the heat exchanger. In addition, the controller 34 can monitor the temperature changes detected by the temperature sensor 21 (the model of the controller 34 is SV-604B-1 , can accurately control the operating status of equipment such as the compressor based on the signal fed back by the temperature sensor 21. The model of the temperature sensor 21 is WZP-230, which is used to monitor the temperature changes inside the external frame 2 in real time and promptly feed back electrical signals) and flexibly adjust the operating status of the first compressor 10 and the second compressor 11. When the ambient temperature is not particularly high, one of the compressors can be controlled to operate to reduce energy consumption. When the ambient temperature is in an ultra-high temperature state, the two compressors are controlled to operate simultaneously, thereby reducing the operating power of the compressor and avoiding overload operation of the compressor, which causes the temperature to be too high and thus affects the service life.

[0037] Working principle: When the ultra-high temperature heat-resistant air conditioner is running, the cooling fan 20 installed on the top of the inner wall of the outer frame 2 is started. Since the fixed frame 32 is at an angle of 15 degrees to the horizontal line, under the action of the cooling fan 20, the hot air flow can be discharged along the gaps between the multiple stacked guide plates. The middle partition 7 separates the internal space of the outer frame 2, so that the spaces where the first heat exchanger 5 and the second heat exchanger 6 are located are independent of each other, avoiding mutual interference of the air flows around the two heat exchangers, and enhancing the heat exchange efficiency between the first heat exchanger 5 and the second heat exchanger 6 and the air; at the same time, on rainy days, rainwater from the outside will be collected by multiple groups of stacked water guide plates 33, and the water guide plates 33 will guide the water to the fixed frame 32. The water flows into the collection box 26 along the fixed frame 32. The inclined panel 27 in the collection box 26 plays a diversion role and introduces the water into the filter tank 28. When the water enters the first filter layer 29, the anthracite in the first filter layer 29 will act on the water. The organic matter and larger suspended solids in the water are filtered and removed, and then the water flows to the second filter layer 30, where the quartz sand in the second filter layer 30 intercepts the fine particles in the water. Then, after the water enters the third filter layer 31, the activated carbon in the third filter layer 31 absorbs the odor and residual impurities in the water, completing the water purification. The purified water enters the water storage cylinder 22. When the temperature sensor 21 detects that the internal temperature of the external frame 2 is too high, the controller 34 starts the water pump 23 in the water storage cylinder 22, and transports the purified water to the spray pipe 25 through the water pipe 24. The spray pipe 25 sprays the water on the surface of the first heat exchanger 5 and the second heat exchanger 6 to assist the heat exchanger in dissipating heat. At the same time, the cleaned water can also flow into the collection box 26 to complete the cycle.When cooling is required, the controller 34 controls the first compressor 10 and the second compressor 11 to start according to the temperature signal. The refrigerant generated by the first compressor 10 is transported to the corresponding inlet pipe through the first refrigerant pipe 8, and then enters the first heat exchanger 5 through the diverter pipe 13. The refrigerant generated by the second compressor 11 is transported to the corresponding inlet pipe through the second refrigerant pipe 9, and then enters the second heat exchanger 6 through the diverter pipe 13. After the refrigerant exchanges heat in the first heat exchanger 5 and the second heat exchanger 6, it flows out through the first outflow pipe 14 and the second outflow pipe 15 respectively and enters the first drying filter 16 and the second drying filter 17. The first drying filter 16 and the second drying filter 17 remove moisture and impurities in the refrigerant. The purified refrigerant is then removed from the heat exchanger, and the purified refrigerant flows through the delivery pipe 18 into the confluence pipe 19, completing the refrigerant cycle. Furthermore, the air permeable plate 4 provided on the surface of the outer frame 2 enhances air circulation inside and outside the outer frame 2, further assisting in heat dissipation by the heat exchanger. Furthermore, the controller 34 can flexibly adjust the operating status of the first compressor 10 and the second compressor 11 based on temperature changes detected by the temperature sensor 21. When the ambient temperature is not particularly high, one of the compressors can be controlled to operate, reducing energy consumption. When the ambient temperature is extremely high, both compressors can be controlled to operate simultaneously, thereby reducing the operating power of the compressors and preventing overloading of the compressors, which would cause them to overheat and affect their service life.
