Description

Technical Field

[0001] This invention relates to the field of industrial air conditioning technology, specifically to an industrial energy-saving air conditioner. Background Technology

[0002] Direct-injection industrial air conditioners achieve temperature control over a long range by outputting direct airflow. However, when moving air along the path of the direct airflow, the surrounding air mainly moves towards the direct airflow in an "L" shape, resulting in weak agitation of the air around the path and an inability to quickly mix hot and cold air. This is especially true around the air outlet. Although the high-speed flow of the direct airflow can accelerate the movement of hot air around the outlet, the speed of the direct airflow is greatest at the outlet, resulting in the worst diffusion of cold air from the outlet. Consequently, the temperature reduction rate at the outlet is smaller than that around the direct airflow path, leading to a poor overall temperature reduction effect. To address these issues, traditional solutions often employ a relatively large number of air conditioning units, with the units opening to the left to improve air circulation efficiency. However, this approach is not only energy-intensive but also significantly increases equipment costs and maintenance expenses due to the large number of units. Therefore, there is a need for an air conditioner that can make the shape of the output airflow not limited to direct airflow. While meeting the temperature influence over a long range, it can also accelerate the exchange efficiency of hot and cold air at the outlet and improve the agitation effect of the air around the movement path under direct airflow, thereby achieving a more efficient and energy-saving environmental regulation effect and reducing the number of air conditioning units. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an industrial energy-saving air conditioner that can effectively solve the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an industrial energy-saving air conditioner, comprising a casing, a compressor, a condenser, an evaporator, an expansion valve, and a refrigerant delivery pipe. The casing contains, from bottom to top, three mounting cavities: a first mounting cavity, a second mounting cavity, and a third mounting cavity. A second ventilation hole is provided on the casing to connect the second mounting cavity with the external space of the casing. An exhaust air channel is provided between the second and third mounting cavities. An air distribution channel is provided within the third mounting cavity, connecting the exhaust air channel and the external space of the casing. Air from outside the casing is drawn into the air distribution channel through the exhaust air channel and the second ventilation hole and cooled by the evaporator. The air distribution channel is used to deliver cold air into the external space of the casing in the form of a direct airflow, a spiral airflow of type one, or a spiral airflow of type two, with the spiral directions of spiral airflow of type one and spiral airflow of type two being opposite.

[0005] Preferably, the air distribution channel includes an installation sleeve, an outer pipe, and an inner pipe. The installation sleeve is fixedly installed between the outer circumferential surface of the outer pipe and the air extraction channel, and the inner cavity of the installation sleeve is connected to the inner cavity of the outer pipe. The inner pipe is axially slidably installed inside the outer pipe, and one end of the inner pipe is sealed by an end plate. The outer circumferential surface of the inner pipe is connected to a first conduit and a second conduit in sequence from near to far from the end plate. The inner pipe reciprocates axially, so that the first conduit and the second conduit are alternately connected to the inner cavity of the installation sleeve.

[0006] Preferably, a connecting pipe is fixedly installed inside the mounting sleeve on the side near the exhaust air channel. The inner cavity of the connecting pipe connects the air outlet of the exhaust air channel and the inner cavity of the mounting sleeve. A spring is provided between the mounting sleeve and the connecting pipe, with one end of the spring axially protruding from the connecting pipe and fixedly connected to multiple push rods. The ends of the multiple push rods away from the spring are all inclined towards the center and are jointly fixedly connected to a central tube. One end of the central tube extends into the connecting pipe, and an adjusting block is fixedly sleeved on its outer circumference. The spring is in a pre-compressed state.

[0007] Preferably, a central shaft is provided at the center of the inner tube, which extends along the central axis of the inner tube and is stationary relative to the inner tube; a spacer is fitted on the outer circumference of the central shaft, which consists of a straight tube part and a tapered part; wherein, the tip of the tapered part points to the end plate and is fixedly connected to the central shaft between the first and second conduits, and a through hole is provided on the tapered part at the position corresponding to the second conduit; a diversion tube is coaxially arranged in the inner tube located between the first and second conduits.

[0008] Preferably, the first conduit is a round tube, the second conduit has a long elliptical cross-section and extends along the axial direction of the inner tube, and the inner diameter of the first conduit is larger than the inner diameter of the second conduit.

[0009] Preferably, when conduit one is connected to the mounting sleeve, the spring pushes the push rod to contact the inner surface of conduit one, and inserts the central tube into the inner cavity of the outer tube between the end plate and the inner tube; when conduit two is connected to the mounting sleeve, the spring pushes the push rod to contact the inner surface of conduit two, and inserts the central tube into the inner cavity of the inner tube between the diverter tube and the spacer, so that the adjusting block closes the annular cavity between the central tube and the connecting tube.

[0010] Preferably, a spiral channel one is formed between the straight tube section and the central axis, a spiral channel two is formed between the straight tube section and the inner tube, and a spiral channel three is formed between the diverter tube, the central axis and the conical section; the end of the diverter tube near the second guide tube opens outward in a funnel shape.

[0011] Preferably, the rotation direction of the first spiral channel is opposite to that of the second spiral channel; the rotation direction of the third spiral channel is the same as that of the second spiral channel.

[0012] Compared with the prior art, the present invention provides an industrial energy-saving air conditioner, which has the following beneficial effects: 1. By setting duct one and duct two on the inner tube, and duct one and duct two can alternately connect to the air outlet of the diversion component; by setting spiral channels one and two coaxially arranged inside the inner tube, with spiral channels one and spiral channels one rotating in opposite directions; and by setting an air distribution duct between the inner tube and the outer casing. When air is supplied through the first duct, the second spiral channel outputs spiral airflow to the outside of the casing. The spiral airflow quickly stirs the hot air around the air outlet, achieving rapid mixing of hot and cold air around the air outlet, thereby achieving rapid reduction of the temperature around the air outlet. When air is supplied through duct two, air can enter both spiral channel one and spiral channel two, and the air intake of both can be adjusted. In this case, spiral airflow can be output from spiral channel one and spiral channel two simultaneously with the same air flow rate. The two spiral airflows dissolve into each other in the air distribution duct to form a direct airflow that is ejected from the air distribution duct, and the direct airflow is used to achieve a long-range temperature effect. Alternatively, the air flow rate output from spiral channel one can be much greater than the air flow rate output from spiral channel two to achieve spiral airflow that is in the same direction as the spiral channels when it is output to the outside of the casing. This spiral airflow is also used to quickly stir the hot air around the air outlet.

[0013] 2. By alternately outputting direct airflow and spiral airflow in the same direction as the spiral channel, the direct airflow is used to push the spiral airflow away from the air outlet quickly, and the spiral airflow is used to stir the hot air around the moving path, thereby improving the stirring effect of the air around the moving path under the direct airflow.

[0014] 3. As described above, this invention outputs both direct airflow and spiral airflow. The direct airflow satisfies the temperature influence over a long range, while the spiral airflow enhances the temperature reduction effect around the air outlet. Furthermore, by alternating the output of direct and spiral airflows, the agitation effect of the air around the moving path under the direct airflow is improved, thereby achieving a more efficient and energy-saving environmental regulation effect and reducing the need for air conditioning equipment.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 8 As shown, this invention provides an industrial energy-saving air conditioner, including a housing 1. Inside the housing 1, from bottom to top, are arranged mounting cavities 101, 102, and 103. The housing 1 has ventilation holes 104 and 105, and a distribution duct 10 is embedded therein. Ventilation hole 104 communicates with mounting cavity 101, enabling communication between mounting cavity 101 and the external space of the housing 1; ventilation hole 105 communicates with mounting cavity 102, enabling communication between mounting cavity 102 and the external space of the housing 1; the inlet of the distribution duct 10 extends into mounting cavity 103, and the outlet of the distribution duct 10 protrudes from the housing 1. External air can enter mounting cavity 102 through ventilation hole 105, and the air in mounting cavity 101 and external air can circulate through ventilation hole 104.

[0019] A spherical pair is formed between the air distribution duct 10 and the housing 1, and the outlet direction of the air distribution duct 10 can be adjusted by rotating the air distribution duct 10.

[0020] The compressor 2, condenser 3, and expansion valve 5 are installed in the first mounting cavity 101, with the condenser 3 cooperating with the first ventilation hole 104; the evaporator 4 is installed in the second mounting cavity 102 near the second ventilation hole 105; a refrigerant delivery pipe is installed between the first mounting cavity 101 and the second mounting cavity 102, and an air guide hole is provided between the second mounting cavity 102 and the third mounting cavity 103; the compressor 2, condenser 3, expansion valve 5, evaporator 4, and refrigerant delivery pipe together form a refrigerant circulation pipeline to cool the air entering the second mounting cavity 102; the cold air in the second mounting cavity 102 is ejected from the casing 1 through the air guide hole and the air distribution pipe 10, realizing the agitation and temperature regulation of the air outside the casing 1.

[0021] The mounting cavity 103 houses a fan 6, a rectifier assembly 7, a distributor assembly 8, and a distributor assembly 9. The air inlet of the fan 6 is embedded in the air guide hole and extends downward into the mounting cavity 102. The air outlet of the fan 6 is connected to the rectifier assembly 7, forming a combined air extraction and supply channel. The air outlet of the rectifier assembly 7 is connected to the distributor assembly 8. The distributor assembly 8, the distributor assembly 9, and the distributor duct 10 are sequentially connected, forming a combined air distribution channel. This air distribution channel connects the air extraction and supply channel to the external space of the housing 1.

[0022] When regulating the temperature of the air outside the casing 1, the compressor 2 drives the refrigerant circulation. The refrigerant in the evaporator 4 works in conjunction with the fan 6 to draw the air outside the casing 1 into the mounting cavity 102 and the rectifier assembly 7 through the second ventilation hole 105, and cools the drawn-in air. The condenser 3 is used to release the heat absorbed by the refrigerant from the evaporator 4. The cold air in the mounting cavity 102 enters the rectifier assembly 7 under the action of the fan 6, and then passes through the distribution assembly 8, the air distribution assembly 9 and the air distribution duct 10 in sequence, and then enters the external space of the casing 1 for temperature regulation.

[0023] It should be noted that in the above technical solution, at least one fan 6 and one rectifier 7 are provided, and the number is the same. Each fan 6 is connected to one rectifier 7 to form an independent air extraction channel. Each of the diversion component 8, air distribution component 9, and air distribution duct 10 is provided at least once and in equal quantities. Each diversion component 8 is connected to an air distribution component 9 and an air distribution duct 10 to form an independent air distribution channel. The ratio of exhaust air ducts to distribution air ducts is 1:N, where N can be 1, 2, 3, or 4. The specific configuration is as follows.

[0024] When the number of exhaust air ducts is 1 and the number of distribution air ducts is also 1, only one distribution air duct 8 is installed on one rectifier assembly 7, and the two are fixedly connected by bolts. Cold air is ejected from the casing 1 through a single distribution air duct; in this case, the layout of the exhaust air ducts, distribution air ducts, and casing 1 can be found in [reference needed]. Figure 1 , Figure 2 and Figure 3 .

[0025] When the number of exhaust air channels is 1 and the number of distribution air channels is 2, there are two installation methods between the rectifier assembly 7 and the distribution assembly 8. Firstly, the two distribution assemblies 8 are bolted to both sides of the rectifier assembly 7, allowing cold air to be distributed from both sides of the rectifier assembly 7 to the two distribution air channels. Secondly, two flow splitting components 8 are installed on the same side of the rectifier component 7 through a connector, so that the cold air in the rectifier component 7 is split into two air distribution channels through the connector; the connector is a combination of bolts and tee pipes, and one opening of the tee pipe is connected to the rectifier component 7, and the other two openings are connected to the two air distribution channels respectively, so as to realize the splitting of cold air.

[0026] When the number of exhaust air channels is 1 and the number of distribution air channels is 3, one of the diversion components 8 is installed on one side of the rectifier component 7 by bolts, and the other two diversion components 8 are installed on the other side of the rectifier component 7 by connectors.

[0027] When the number of exhaust air channels is 1 and the number of distribution air channels is 4, the four distribution air channels are grouped in pairs and installed on both sides of the rectifier assembly 7 through two connectors.

[0028] When the number of exhaust air channels is greater than 2, the combination of exhaust air channels with distribution air channels can refer to the configuration principle when the number of exhaust air channels is 1, which will not be repeated in this article.

[0029] As a further explanation of the above technical solution, such as Figure 4 As shown, the rectifier assembly 7 includes a rectifier housing 71. The bottom end of the rectifier housing 71 is fixedly connected to the housing of the fan 6. A spiral air duct 72 is provided inside the rectifier housing 71. An air guide hole 73 is provided at the bottom end of the rectifier housing 71. The air guide hole 73 serves as the air inlet of the rectifier assembly 7, connecting the outer opening of the spiral air duct 72 with the air outlet of the fan 6. Air guide holes 74 are provided at both ends of the rectifier housing 71 at positions corresponding to the center position of the spiral air duct 72. Both air guide holes 74 can be used as air outlets of the rectifier assembly 7.

[0030] The cold air supplied by fan 6 flows along spiral duct 72 and then exits through air guide hole 74 from rectifier housing 71. Spiral duct 72 rectifies and reverses the cold air discharged from the outlet of fan 6.

[0031] It should be noted that, in order to reduce the noise when cold air flows along the spiral duct 72, flexible sound-absorbing panels can be attached to the wall of the spiral duct 72.

[0032] As a further explanation of the above technical solution, such as Figure 5 and Figure 6As shown, the diversion assembly 8 includes a flange ring 81. One end of the flange ring 81 is fixedly installed on the rectifier housing 71 by bolts or connectors. The other end of the flange ring 81 is coaxially fixed with a connecting pipe 82 and a mounting sleeve 83. The mounting sleeve 83 is located outside the connecting pipe 82 and axially protrudes from the connecting pipe 82. The inner cavity of the mounting sleeve 83 is connected to the air guide hole 74 through the central hole of the flange ring 81 and the inner cavity of the connecting pipe 82. A spring 86 is provided between the mounting sleeve 83 and the connecting pipe 82, with one end of the spring 86 axially protruding from the connecting pipe 82 and fixedly connected to the connecting ring 88; a plurality of push rods 85 are fixedly connected to the end of the connecting ring 88 away from the spring 86, and the ends of the plurality of push rods 85 away from the connecting ring 88 are all inclined toward the center and are jointly fixedly connected to the central pipe 84; one end of the central pipe 84 extends toward the connecting pipe 82 and an adjusting block 87 is fixedly sleeved on its outer circumference.

[0033] The other end of the spring 86 abuts against the flange ring 81; the spring 86 is in a pre-compressed state; the elastic deformation of the spring 86 allows the central tube 84 to move axially, and drives the adjusting block 87 to move into or out of the connecting tube 82, thereby closing or opening the annular cavity between the outer circumferential surface of the central tube 84 and the inner circumferential surface of the connecting tube 82. When the annular cavity is open, the air in the connecting tube 82 is discharged through the annular cavity and the inner cavity of the central tube 84; when the annular cavity is closed, the air in the connecting tube 82 is discharged through the inner cavity of the central tube 84.

[0034] It should be noted that when only one air guide hole 74 is connected to the center hole of the flange ring 81, the air guide hole 74 serves as the air outlet of the rectifier assembly 7, while the other air guide hole 74 is sealed by the sealing plate.

[0035] As a further explanation of the above technical solution, such as Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the air distribution assembly 9 includes an outer tube 91, an inner tube 93, and a lead screw 94.

[0036] One end of the outer tube 91 is fixedly connected to the mounting plate 92, which is fixedly connected to the housing 1; the other end of the outer tube 91 is connected to the air distribution pipe 10 through the flexible hose 11, which connects the inner cavity of the outer tube 91 with the inner cavity of the air distribution pipe 10; the outer circumferential surface of the outer tube 91 is fixedly connected to the mounting sleeve 83, and the inner cavity of the mounting sleeve 83 is connected to the inner cavity of the outer tube 91.

[0037] The inner tube 93 is coaxially disposed inside the outer tube 91 and forms an axial sliding connection with the outer tube 91; the outer circumferential surface of the inner tube 93 is connected to the first conduit 901 and the second conduit 902, and the first conduit 901 is located between the mounting plate 92 and the second conduit 902; the first conduit 901 and the second conduit 902 are alternately connected to the mounting sleeve 83 by sliding the inner tube 93.

[0038] When conduit 1 901 is connected to the mounting sleeve 83, spring 86 pushes push rod 85 to contact the inner surface of conduit 1 901 and inserts central tube 84 into the inner cavity of outer tube 91 between end plate 931 and inner tube 93; when conduit 2 902 is connected to the mounting sleeve 83, spring 86 pushes push rod 85 to contact the inner surface of conduit 2 902 and inserts central tube 84 into the inner cavity of inner tube 93.

[0039] The first conduit 901 is a circular tube, and the second conduit 902 has an elongated elliptical cross-section and extends axially along the inner tube 93. The inner diameter of the first conduit 901 is larger than the inner diameter of the second conduit 902, so that the depth to which the central tube 84 is inserted into the inner tube 93 through the inner cavity of the first conduit 901 is greater than the depth to which it is inserted through the second conduit 902. When the central tube 84 is inserted into the inner cavity of the inner tube 93 through the second conduit 902, the adjusting block 87 closes the annular cavity. Figure 8 As shown.

[0040] A guide groove is provided on the inner circumferential surface of the outer tube 91. The guide groove extends along the axial direction of the outer tube 91. Both guide tube 901 and guide tube 902 are located in the guide groove to guide the axial sliding of the inner tube 93.

[0041] A lead screw 94 is positioned at the center of the outer tube 91 and extends along the central axis of the outer tube 91. One end of the lead screw 94 extends into the inner tube 93, and a central shaft 95 is screwed onto its outer circumference. The central shaft 95 extends along the central axis of the inner tube 93 and is relatively stationary relative to the inner tube 93. The other end of the lead screw 94 protrudes from the outer tube 91 and passes through and is rotatably connected to the mounting plate 92. A motor 12 for driving the lead screw 94 to rotate is mounted on the mounting plate 92. The motor 12 is connected to the lead screw 94 via a synchronous pulley and synchronous belt transmission assembly. By rotating the lead screw 94 forward and backward, the central shaft 95 and the inner tube 93 reciprocate axially along the central axis of the outer tube 91, thereby enabling the first conduit 901 and the second conduit 902 to alternately communicate with the inner cavity of the mounting sleeve 83.

[0042] A spacer 96 is fitted on the outer circumference of the central shaft 95. The spacer 96 consists of a straight tube section and a tapered section. The tip of the tapered section points to the mounting plate 92 and is fixedly connected to the central shaft 95 between the first guide tube 901 and the second guide tube 902. A through hole 903 is provided on the tapered section at the position corresponding to the second guide tube 902. The straight tube section extends away from the mounting plate 92, and a spiral channel 1 is formed between the straight tube section and the central shaft 95. A spiral channel 2 is formed between the straight tube section and the inner tube 93. The spiral direction of the first spiral channel is opposite to that of the second spiral channel. A diverter tube 97 is coaxially arranged in the inner tube 93 between the first conduit 901 and the second conduit 902. The end of the diverter tube 97 near the second conduit 902 opens outward in a funnel shape, and a spiral channel three is formed between the diverter tube 97, the central shaft 95 and the conical part. The spiral channel three rotates in the same direction as the spiral channel two. An air acceleration chamber is formed between the diverter tube 97 and the inner tube 93.

[0043] The mounting plate 92 has an air hole, and an end plate 931 is fixedly connected to one end of the inner tube 93 facing the mounting plate 92. The end plate 931 is screwed to the outer surface of the lead screw 94. The air hole is used to connect the inner cavity of the outer tube 91 between the end plate 931 and the mounting plate 92 with the external environment to facilitate the axial sliding of the inner tube 93.

[0044] The air distribution method of the air distribution channel is as follows: Before air distribution, the conduit 901 is connected to the mounting sleeve 83. The central tube 84 and the push rod 85 are inserted into the inner cavity of the inner tube 93 through the conduit 901 under the push of the spring 86, and the push rod 85 abuts against the inner surface of the conduit 901. The central tube 84 extends to the area between the diversion tube 97 and the end plate 931. The annular cavity between the central tube 84 and the connecting tube 82 is in the open state. During air replenishment, the cold air from the exhaust duct enters the inner tube 93 through the annular cavity and the inner cavity of the central tube 84. Part of the cold air enters the spiral channel three between the split tube 97 and the central shaft 95, forming spiral airflow three. The other part of the cold air enters the air acceleration chamber between the split tube 97 and the inner tube 93, forming high-speed airflow. After exiting the air acceleration chamber, the high-speed airflow quickly passes through the area between the straight pipe and the split tube 97, and then quickly enters the spiral channel two, forming spiral airflow two. During the process of the high-speed airflow passing through the area between the straight pipe and the split tube 97, the Bernoulli effect is used to drive the spiral airflow three into the spiral channel two, so that the airflow from the spiral channel two enters the air distribution duct 10 at high speed and in a spiral state, and then enters the outer space of the casing 1, agitating and regulating the temperature of the air outside the casing 1. During the air replenishment process, the motor 12 drives the lead screw 94 to rotate, causing the end plate 931, central shaft 95, and inner tube 93 to move towards the mounting plate 92, pushing the push rod 85 towards the flange ring 81, causing the central tube 84 to fully enter the inner cavity of the mounting sleeve 83, compressing the spring 86. Then, the inner tube 93 continues to move towards the mounting plate 92, moving the second guide tube 902 to communicate with the mounting sleeve 83. The spring 86 pushes the push rod 85 and the central tube 84 through the second guide tube 902 into the inner tube 93, and makes the push rod 85 abut against the inner surface of the central tube 84. The adjusting block 8... 7. The annular cavity between the central tube 84 and the connecting tube 82 is closed. The central tube 84 extends to the inner cavity of the inner tube 93 between the split tube 97 and the partition 96, so that the cold air coming out of the exhaust air channel enters the inner cavity of the inner tube 93 between the split tube 97 and the partition 96 through the inner cavity of the central tube 84. A part of the cold air enters the spiral channel one through the through hole 903 to form spiral airflow one, and another part of the cold air enters the spiral channel two to form spiral airflow two. Spiral airflow one and spiral airflow two merge with each other in the air distribution pipe 10 to form a direct airflow that acts on the outer space of the casing 1. When the central tube 84 is located at the second conduit 902, the inner tube 93 is moved by the motor 12, causing the second conduit 902 to move axially relative to the central tube 84. This adjusts the relative position of the central tube 84 and the through hole 903, thereby adjusting the airflow rate entering the first spiral channel and the airflow rate entering the second spiral channel. When the airflow rate entering the first spiral channel is much greater than the airflow rate entering the second spiral channel, the second spiral airflow is converted into the first spiral airflow in the air distribution pipe 10, so that the airflow coming out of the air distribution pipe 10 is only the first spiral airflow, which agitates and regulates the temperature of the air outside the casing 1.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
