Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning energy-saving control, in particular to an energy-saving control device for a factory air-conditioning. Background Art

[0002] Industrial air conditioning refers to air-conditioning equipment that provides environmental temperature, humidity, and cleanliness guarantees for the reliable operation of industrial product production processes or industrial process equipment. For example, constant temperature and humidity air conditioners used to ensure the normal operation of equipment in electrical control rooms, special air conditioners for high-temperature environments used in mobile bridge cranes in steelmaking workshops, low-temperature unit air conditioners used in meat processing workshops, etc., all belong to industrial air conditioners.

[0003] The announcement number is CN216132023U, a factory air-conditioning system for each workshop, including a rectangular closed cavity, an air inlet is arranged on the side wall close to the ground at one end of the length direction of the rectangular closed cavity, and an air outlet is opened on the top surface of the other end. Along the length direction of the rectangular closed cavity, a first cavity, a second cavity, a third cavity, a fourth cavity and a fifth cavity are arranged in sequence. When the factory air-conditioning is in operation, it is necessary to absorb the outside air into the inside of the outdoor unit, and then condense and cool the absorbed air through the hydraulic condenser inside the outdoor unit. This cooling method will accumulate a large amount of high-temperature heat source around the outdoor unit of the factory air-conditioning. When the outdoor unit of the factory is in operation again, it will absorb the outside air for cooling and convert the high-temperature gas into low-temperature gas, which will greatly increase the energy consumption.

[0004] In the current existing technology, when the air conditioner is in operation, it needs to absorb the outside air into the outside unit, and then condense and cool the absorbed air through the hydraulic condenser inside the outside unit. However, the existing factory air-conditioning outdoor units are all located at the top of the factory building. When condensing and converting hot air, the heat source generated will increase and accumulate around the outdoor unit, so that the temperature absorbed into the inside of the outdoor unit will be higher than the normal temperature, and the energy required will be higher than the normal consumption, which will cause a certain amount of resource waste. Moreover, when the cold air guide pipe is guiding cold air, the output end of the guide pipe is closest to the factory air-conditioning outdoor unit, so that the temperature at this position is closest to the temperature when the factory air-conditioning outdoor unit discharges cold air, and a large amount of low-temperature cold air will accumulate at this position. The accumulation of low-temperature cold air will cause the problem of low-temperature waste.

[0005] Therefore, in order to solve the above problems, a factory air-conditioning energy-saving control device is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Specific examples are given below.

[0027] See also Figure 1 - Figure 6The utility model provides an energy-saving control device for a factory air conditioner, comprising an outdoor unit 11 for the factory air conditioner and a cold water square pipe 12 fixedly mounted on the bottom surface of the outdoor unit 11 for the factory air conditioner, a support frame 13 symmetrically fixedly mounted on the surfaces of both sides of the outdoor unit 11 for the factory air conditioner and the cold water square pipe 12, a guide square pipe 14 fixedly mounted on the surface of the other side of the outdoor unit 11 for the factory air conditioner, a drainage pipe 141 fixedly connected to the inner wall surface of the guide square pipe 14, a bell mouth 142 is provided on the top surface of the drainage pipe 141, a discharge pipe 143 is provided on the inner wall surface of the guide square pipe 14 and at the bottom edge position of the drainage pipe 141, a double-layer hollow box 2 144 is fixedly mounted on the back side of the guide square pipe 14, and one end of the drainage pipe 141 and the bell mouth 142 respectively pass through the guide square pipe 14 and extend to the upper and lower inner walls of the double-layer hollow box 2 144, An exhaust pipe 2 146 and an air intake pipe 2 145 are fixedly connected to the outer surface of the core box 2 144, and one end of the air intake pipe 2 145 and the exhaust pipe 2 146 are respectively connected to the drainage pipe 141 and the drain pipe 143 on the inner wall of the double-layer hollow box 2 144; a double-layer hollow box 126 is fixedly connected to the outer surface of the cold water square tube 12, and an air intake pipe 127 and an exhaust pipe 128 are respectively fixedly connected to the outer surface of the double-layer hollow box 126, and the other ends of the air intake pipe 127 and the exhaust pipe 128 are connected to the air intake pipe 2 145 and the double-layer hollow box 126; a U-shaped cooling pipe 123 is fixedly connected to the inner wall of the cold water square tube 12, and both ends of the U-shaped cooling pipe 123 pass through the cold water square tube 12 and extend to the interior of the double-layer hollow box 126 to be connected to the air intake pipe 127 and the exhaust pipe 128;

[0028] During operation, the factory air-conditioning outdoor unit 11 cooperates with the factory air-conditioning outdoor unit 11 to inject the cooled low-temperature cold air into the interior of the guide square tube 14. The high-speed flowing low-temperature cold air will contact the bell mouth 142 on the top surface of the guide tube 141, and the opened bell mouth 142 will be used to inject the rapidly downward-flowing airflow into the interior of the guide tube 141. Under the subsequent push of the low-temperature gas, the air flow inside the guide tube 141 will pass through the double-layer hollow box 2 144 and the air intake pipe 2 145, and then flow into the air intake pipe 1 127, the double-layer hollow box 1 126 and the interior of the U-shaped cooling tube 123. When the low-temperature cold air contacts the U-shaped cooling tube 123, it will quickly absorb the heat source on the surface of the U-shaped cooling tube 123, and then quickly reduce the surface temperature of the U-shaped cooling tube 123, so that the high-temperature air flowing inside the cold water square tube 12 contacts the surface of the U-shaped cooling tube 123, and the heat exchange cooling is used. The high-temperature gas inside the water square tube 12 is quickly cooled; the gas after absorbing heat will be re-injected into the double-layer hollow box 126 and the exhaust pipe 128 under the push of the subsequent low-temperature gas. As the gas is continuously pushed, the low-temperature gas will be re-injected into the interior of the discharge pipe 143. The downward vertical angle of the discharge pipe 143 is used to inject the gas after absorbing heat into the interior of the guide square tube 14, and mix with the low-temperature gas inside to cool it. At the same time, the push of the gas can accelerate the fluidity of the gas inside the guide square tube 14, so that the low-temperature gas accumulated at the inlet of the guide square tube 14 can flow quickly, avoiding the output end of the guide tube being closest to the factory air-conditioning outdoor unit so that the temperature at this position is closest to the temperature when the factory air-conditioning outdoor unit discharges cold air, and a large amount of low-temperature cold air will be accumulated at this position, and the accumulation of low-temperature cold air will cause waste of low-temperature gas.

[0029] Further, such as Figures 1 to 6 As shown, a baffle plate 121 arranged on the bottom edge of the U-shaped cooling tube 123 is fixedly connected to the inner wall of the cold water square tube 12, and a guide chute 124 is provided on the edge of one end of the baffle plate 121 at the entrance of the cold water square tube 12. A sealing rubber ring 122 is fixedly connected to the inner wall of the cold water square tube 12, and the inner wall of the sealing rubber ring 122 is detachably mounted on the outer surface of one end of the U-shaped cooling tube 123. A filter box 125 is movably sleeved on the inner wall of the cold water square tube 12. There is a honeycomb plate that is movably attached to the outer surface of the filter box 125, and a hydraulic brake 111 is provided on one side surface of the factory air-conditioning outdoor unit 11 and at the top edge position of the cold water square pipe 12. The output end of the hydraulic brake 111 is fixedly connected to a filter screen plate 112 that is movably overlapped on the edge position of the inlet of the factory air-conditioning outdoor unit 11. An air guide pipe 113 arranged on the outer surface of the filter screen plate 112 is fixedly installed on the outer surface of the output end of the hydraulic brake 111, and the other end of the air guide pipe 113 is fixedly connected to the top surface of the cold water square pipe 12.

[0030] During operation, it cooperates with the factory air-conditioning outdoor unit 11 to absorb the outside air, and the strong suction force will absorb the air from one end of the air duct 113, and cooperate with one end of the cold water square pipe 12 to recover the air escaped from the factory building, and guide the absorbed gas into the inside of the cold water square pipe 12. The flowing gas will contact the U-shaped cooling pipe 123 inside the cold water square pipe 12. The low temperature environment on the surface of the U-shaped cooling pipe 123 will interact with the flowing gas as a heat source, and the cooled gas will flow into the inside of the filter box 125 for dust filtration. The filtered low-temperature gas will pass through the air duct 113 and enter the inside of the factory air-conditioning outdoor unit 11. At this time, the low-temperature gas will be mixed with the high-temperature air from the outside absorbed by the factory air-conditioning outdoor unit 11 for cooling. The cooled high-temperature gas will gradually tend to the normal outdoor temperature, greatly reducing the energy consumption.

[0031] Working principle: Cooperate with the factory air-conditioning outdoor unit 11 to inject the cooled low-temperature cold air into the interior of the guide square tube 14, and the high-speed flowing low-temperature cold air will contact the bell mouth 142 on the top surface of the guide tube 141. The opened bell mouth 142 is used to inject the rapidly downward-flowing airflow into the interior of the guide tube 141. Under the subsequent push of the low-temperature gas, the air inside the guide tube 141 will pass through the double-layer hollow box 2 144 and the interior of the intake pipe 2 145, and then flow into the interior of the intake pipe 1 127, the double-layer hollow box 1 126 and the U-shaped cooling tube 123. When the low-temperature cold air contacts the U-shaped cooling tube 123, it will quickly absorb the heat source on the surface of the U-shaped cooling tube 123, thereby quickly reducing the surface temperature of the U-shaped cooling tube 123, so that the high-temperature air flowing inside the cold water square tube 12 contacts the surface of the U-shaped cooling tube 123, and the high-temperature air inside the cold water square tube 12 is quickly cooled by heat exchange;

[0032] The heat-absorbing gas is then pushed by the subsequent low-temperature gas to be re-injected into the double-layer hollow box 126 and the exhaust pipe 128. As the gas is continuously pushed, the low-temperature gas is re-injected into the interior of the drainage pipe 143. The downward vertical angle of the drainage pipe 143 is used to inject the heat-absorbing gas into the interior of the guide square tube 14, where it mixes with the low-temperature gas inside and is cooled. At the same time, the push of the gas can accelerate the flow of the gas inside the guide square tube 14, causing the low-temperature gas accumulated at the entrance of the guide square tube 14 to flow rapidly.

[0033] Cooperate with the factory air-conditioning outdoor unit 11 to absorb the outside air, and the strong suction force will absorb the air at one end of the air duct 113, cooperate with one end of the cold water square pipe 12 to recover the air escaped from the factory building, and guide the absorbed gas into the inside of the cold water square pipe 12. The flowing gas will contact the U-shaped cooling pipe 123 inside the cold water square pipe 12. The low temperature environment on the surface of the U-shaped cooling pipe 123 will interact with the flowing gas as a heat source. The cooled gas will flow into the inside of the filter box 125 for dust filtration. The filtered low-temperature gas will pass through the air duct 113 and enter the inside of the factory air-conditioning outdoor unit 11. At this time, the low-temperature gas will be mixed with the high-temperature air absorbed by the factory air-conditioning outdoor unit 11 to cool down. The cooled high-temperature gas will gradually tend to the normal outdoor temperature, greatly reducing the energy consumption.
