Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial air conditioning, in particular to an industrial energy-saving air conditioner. BACKGROUND

[0002] The direct injection type industrial air conditioner realizes temperature influence on a long range by outputting direct air flow, but when driving the air around the moving path, the surrounding air mainly moves along the "L" shaped track to the direct air flow, so that the stirring effect on the air around the moving path is weak, and the mixing of cold and hot air flow cannot be realized quickly, especially around the air outlet, although the flow speed of the hot air around the air outlet can be accelerated by the high-speed flow of the direct air flow, but because the speed of the direct air flow is the largest at the air outlet, the diffusion effect of the cold air around the air outlet is also the worst, so that the temperature reduction speed at the air outlet and the temperature reduction speed around the moving path of the direct air flow are both small, resulting in poor overall temperature reduction effect. In order to solve the above problems, the traditional scheme usually adopts the mode of arranging relatively enough air conditioning equipment and opening the left air conditioning equipment to improve the air circulation efficiency, but this mode not only has high energy consumption, but also causes the equipment cost and maintenance cost to increase greatly due to too many equipment. Therefore, an air conditioner is needed, which can make the form of the output air flow not limited to direct air flow, can accelerate the air exchange efficiency of the air outlet, improve the stirring effect of the air around the moving path under the direct air flow, so as to realize more efficient and energy-saving environmental regulation effect, and realize the reduction of air conditioning equipment.

[0017] The technical solutions in the embodiments of the present application will be apparently and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without any creative work fall within the protection scope of the present application.

[0018] Please refer to Figures 1 to 8 As shown in the drawings, the present application provides an industrial energy-saving air conditioner, which comprises a casing 1. The casing 1 is internally provided with an installation cavity one 101, an installation cavity two 102 and an installation cavity three 103 from bottom to top. The casing 1 is provided with a ventilation hole one 104 and a ventilation hole two 105, and is embedded with a wind distribution pipe 10. The ventilation hole one 104 is communicated with the installation cavity one 101, so as to realize the communication between the installation cavity one 101 and the outside space of the casing 1. The ventilation hole two 105 is communicated with the installation cavity two 102, so as to realize the communication between the installation cavity two 102 and the outside space of the casing 1. The inlet of the wind distribution pipe 10 extends into the installation cavity three 103, and the outlet of the wind distribution pipe 10 is exposed outside the casing 1. The outside air of the casing 1 can enter the installation cavity two 102 through the ventilation hole two 105, and the air in the installation cavity one 101 and the outside air of the casing 1 form an air circulation through the ventilation hole one 104.

[0019] The wind distribution pipe 10 and the casing 1 form a spherical pair, so that the outlet direction of the wind distribution pipe 10 can be adjusted by rotating the wind distribution pipe 10.

[0020] The compressor 2, the condenser 3 and the expansion valve 5 are installed in the installation cavity 1, wherein the condenser 3 is matched with the vent 104; the evaporator 4 is installed in the installation cavity 2 near the vent 105; the refrigerant delivery pipe is installed between the installation cavity 1 and the installation cavity 2, and the air guide hole is arranged between the installation cavity 2 and the installation cavity 3; the compressor 2, the condenser 3, the expansion valve 5, the evaporator 4 and the refrigerant delivery pipe jointly form a refrigerant circulation pipeline to cool the air entering the installation cavity 2; the cold air in the installation cavity 2 is sprayed out of the casing 1 through the air guide hole and the air distribution pipe 10 to realize the agitation and temperature adjustment of the air outside the casing 1.

[0021] The fan 6, the rectifier assembly 7, the shunt assembly 8 and the air distribution assembly 9 are arranged in the installation cavity 3. The air inlet of the fan 6 is embedded in the air guide hole and extends downward into the installation cavity 2, and the air outlet of the fan 6 is communicated with the rectifier assembly 7 to jointly form an air suction and delivery channel.

[0022] When the air outside the casing 1 is temperature-adjusted, the compressor 2 drives the refrigerant circulation, and the refrigerant in the evaporator 4 cooperates with the fan 6 to suck the air outside the casing 1 into the installation cavity 2 and the rectifier assembly 7 through the vent 105 and cool the sucked air; the condenser 3 is used to release the heat absorbed by the refrigerant from the evaporator 4. The cold air in the installation cavity 2 enters the rectifier assembly 7 under the action of the fan 6, then sequentially passes through the shunt assembly 8, the air distribution assembly 9 and the air distribution pipe 10, and then enters the space outside the casing 1 to be temperature-adjusted.

[0023] It should be noted that in the above technical solution, the fan 6 and the rectifier assembly 7 are each provided at least one and the same number, each fan 6 is connected with one rectifier assembly 7 to form an independent air suction and delivery channel; The shunt assembly 8, the air distribution assembly 9 and the air distribution pipe 10 are each provided at least one and the same number, and each shunt assembly 8 is connected with one air distribution assembly 9 and one air distribution pipe 10 to form an independent air distribution channel; The number ratio of the air suction and delivery channel to the air distribution channel is 1:N, wherein N can be 1, 2, 3 or 4. The specific configuration is as follows.

[0024] When the number of the air suction and delivery channel is 1 and the number of the air distribution channel is also 1, only one shunt assembly 8 is installed on one rectifier assembly 7, and the two are fixedly connected by bolts. The cold air is sprayed out of the casing 1 through a single air distribution channel; in this case, the layout of the air suction and delivery channel, the air distribution channel and the casing 1 can be referred to Figure 1 ,Figure 2 and Figure 3 .

[0025] When the number of air extraction and supply channels is 1 and the number of air distribution channels is 2, the installation mode between the rectifying assembly 7 and the distributing assembly 8 has the following two modes. One is that two distributing assemblies 8 are respectively installed on the two sides of the rectifying assembly 7 by bolts, so that the cold air can be distributed from the two sides of the rectifying assembly 7 to the two air distribution channels; The other is that two distributing assemblies 8 are installed on the same side of the rectifying assembly 7 by a connecting piece, so that the cold air in the rectifying assembly 7 is distributed to the two air distribution channels through the connecting piece. The connecting piece is a combination of a bolt and a tee pipe, and one opening of the tee pipe is connected with the rectifying assembly 7, and the other two openings are respectively connected with the two air distribution channels, so as to realize the distribution of the cold air.

[0026] When the number of air extraction and supply channels is 1 and the number of air distribution channels is 3, one of the distributing assemblies 8 is installed on one side of the rectifying assembly 7 by a bolt, and the other two distributing assemblies 8 are installed on the other side of the rectifying assembly 7 by a connecting piece.

[0027] When the number of air extraction and supply channels is 1 and the number of air distribution channels is 4, the four air distribution channels are grouped in pairs, and are respectively installed on the two sides of the rectifying assembly 7 by two connecting pieces.

[0028] When the number of air extraction and supply channels is greater than 2, the combination mode with the air distribution channels can refer to the configuration principle when the number of air extraction and supply channels is 1, which will not be described herein.

[0029] As a further description of the above technical solution, as shown in Figure 4 The rectifying assembly 7 includes a rectifying shell 71, the bottom end of the rectifying shell 71 is fixedly connected with the shell of the fan 6, a spiral air duct 72 is arranged in the rectifying shell 71, a guide air hole one 73 is formed in the bottom end of the rectifying shell 71, the guide air hole one 73 is used as the air inlet of the rectifying assembly 7 to communicate the outside opening of the spiral air duct 72 with the air outlet of the fan 6, and the two ends of the rectifying shell 71 are respectively provided with guide air holes two 74 corresponding to the center positions of the spiral air duct 72. The two guide air holes two 74 can be used as the air outlets of the rectifying assembly 7.

[0030] The cold air sent by the fan 6 flows along the spiral air duct 72, and then is discharged from the rectifying shell 71 through the guide air holes two 74. The cold air discharged from the air outlet of the fan 6 is rectified and reversed by the spiral air duct 72.

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

[0032] As a further description of the above technical solution, as shown in Figure 5 and Figure 6As shown, the flow distribution assembly 8 comprises a flange ring 81, one end of which is fixedly installed on the rectifier shell 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 exposes the connecting pipe 82; the inner cavity of the mounting sleeve 83 is communicated with the air guide hole two 74 through the central hole of the flange ring 81 and the inner cavity of the connecting pipe 82; A spring 86 is arranged between the mounting sleeve 83 and the connecting pipe 82, one end of which axially exposes the connecting pipe 82 and is fixedly connected with a connecting ring 88; a plurality of jacks 85 are fixedly connected with the connecting ring 88 away from the spring 86, one end of each of the plurality of jacks 85 away from the connecting ring 88 is inclined to the center, and a central pipe 84 is fixedly connected with the plurality of jacks 85.

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

[0034] It should be noted that when only one air guide hole two 74 is communicated with the central hole of the flange ring 81, the air guide hole two 74 serves as the air outlet of the rectifier assembly 7, and the other air guide hole two 74 is sealed by the sealing plate.

[0035] As further illustrated in Figure 3 , Figure 5 , Figure 6 and Figure 7 , the air distribution assembly 9 comprises an outer pipe 91, an inner pipe 93 and a lead screw 94.

[0036] One end of the outer pipe 91 is fixedly connected with a mounting plate 92, and the mounting plate 92 is fixedly connected with the machine shell 1; the other end of the outer pipe 91 is connected with the air distribution pipe 10 through the hose 11, so as to communicate the inner cavity of the outer pipe 91 with the inner cavity of the air distribution pipe 10; the outer circumferential surface of the outer pipe 91 is fixedly connected with the mounting sleeve 83, and the inner cavity of the mounting sleeve 83 is communicated with the inner cavity of the outer pipe 91.

[0037] The inner pipe 93 is coaxially arranged in the outer pipe 91 and axially slidably connected with the outer pipe 91; the outer circumferential surface of the inner pipe 93 is communicated with a guide pipe one 901 and a guide pipe two 902, and the guide pipe one 901 is located between the mounting plate 92 and the guide pipe two 902; the guide pipe one 901 and the guide pipe two 902 are alternately communicated with the mounting sleeve 83 by sliding the inner pipe 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. The shunt pipe 97 is coaxially arranged in the inner pipe 93 inner cavity between the conduit one 901 and the conduit two 902, the shunt pipe 97 is outwardly flared to a trumpet mouth shape near one end of the conduit two 902, and the shunt pipe 97, the central shaft 95 and the tapered portion form a spiral channel three; the spiral direction of the spiral channel three is the same as that of the spiral channel two; the air acceleration cavity is formed between the shunt pipe 97 and the inner pipe 93.

[0043] The mounting plate 92 is provided with an air hole, the end plate 931 is fixedly connected to one end of the inner pipe 93 facing the mounting plate 92, and the end plate 931 is screwed with the outer surface of the screw rod 94; the air hole is used for connecting the outer pipe 91 inner cavity between the end plate 931 and the mounting plate 92 with the external environment, so as to facilitate the axial sliding of the inner pipe 93.

[0044] The air distribution mode of the air distribution channel is as follows: Before air distribution, the conduit one 901 is communicated with the mounting sleeve 83, the central pipe 84 and the top rod 85 are inserted into the inner pipe 93 inner cavity through the conduit one 901 under the pushing of the spring 86, and the top rod 85 abuts against the inner surface of the conduit one 901, the central pipe 84 extends to the region between the shunt pipe 97 and the end plate 931, and the annular cavity between the central pipe 84 and the connecting pipe 82 is in an open state; When air is supplemented, the cold air from the air suction and conveying channel enters the inner pipe 93 through the annular cavity and the central pipe 84 inner cavity, part of the cold air enters the spiral channel three between the shunt pipe 97 and the central shaft 95 to form the spiral airflow three, and the other part of the cold air enters the air acceleration cavity between the shunt pipe 97 and the inner pipe 93 to form the high-speed airflow; after the high-speed airflow comes out of the air acceleration cavity, it quickly passes through the region between the straight pipe portion and the shunt pipe 97, and then quickly enters the spiral channel two to form the spiral airflow two; in the process of passing through the region between the straight pipe portion and the shunt pipe 97, the high-speed airflow drives the spiral airflow three into the spiral channel two by using Bernoulli effect, so that the airflow from the spiral channel two enters the air distribution pipe 10 in a high-speed and spiral state, and then enters the space outside the casing 1 to agitate and temperature-regulate the air outside the casing 1; In the air supplement process, the motor 12 drives the screw rod 94 to rotate, drives the end plate 931, the center shaft 95 and the inner tube 93 to move to one side of the mounting plate 92, drives the top rod 85 to move to the flange ring 81, drives the center tube 84 to move into the inner cavity of the mounting sleeve 83 completely, compresses the spring 86, then the inner tube 93 continues to move to one side of the mounting plate 92, moves the duct two 902 to communicate with the mounting sleeve 83, the spring 86 drives the top rod 85 and the center tube 84 to insert into the inner tube 93 through the duct two 902, and the top rod 85 abuts against the inner surface of the center tube 84, the adjusting block 87 closes the annular cavity between the center tube 84 and the connecting tube 82, the center tube 84 extends into the inner cavity of the inner tube 93 between the shunt tube 97 and the spacer sleeve 96, the cold air from the air suction and supply channel enters the inner cavity of the inner tube 93 between the shunt tube 97 and the spacer sleeve 96 through the inner cavity of the center tube 84, a part of the cold air enters the spiral channel one through the through hole 903 to form the spiral airflow one, and the other part of the cold air enters the spiral channel two to form the spiral airflow two, the spiral airflow one and the spiral airflow two are merged in the air distribution pipe 10 to form the straight airflow, and the straight airflow acts on the space outside the shell 1. When the center tube 84 is located in the duct two 902, the motor 12 drives the inner tube 93 to move, the duct two 902 moves axially relative to the center tube 84, the relative position between the center tube 84 and the through hole 903 is adjusted, the air flow entering the spiral channel one and the air flow entering the spiral channel two are adjusted, and when the air flow entering the spiral channel one is much larger than the air flow entering the spiral channel two, the spiral airflow two is converted into the spiral airflow one in the air distribution pipe 10, so that the air flow from the air distribution pipe 10 is only the spiral airflow one, and the air outside the shell 1 is stirred and temperature adjusted.

[0045] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
