Specific embodiments

[0019] The following combines the drawings with relevant embodiments to illustrate the implementation manners of the present invention. The implementation manners of the present invention are not limited to the following embodiments, and the relevant necessary components involved in the present invention should be regarded as well-known technologies in the technical field, which can be known and mastered by those skilled in the technical field.

[0020] An in-row air conditioner refrigeration system that can operate for a long time, comprising an outdoor unit 1 and an indoor unit 2 connected to the outdoor unit 1. The indoor unit 2 includes a chassis 3. Inside the chassis 3, a filter 4, a condenser 5, and a circulation fan 6 are sequentially arranged in the air inlet and outlet direction. A self-cleaning and dust-removing circulation system is also provided inside the chassis 3. The self-cleaning and dust-removing circulation system consists of an execution group 7 and a resource group 8. The execution group 7 is composed of a filter cleaning part 9 arranged at the filter 4, a condenser cleaning part 10 arranged at the condenser 5, a circulation fan cleaning part 11 arranged at the circulation fan 6, a space cleaning part one 12 and a space cleaning part two 13 in two adjacent spaces. The resource group 8 is composed of a cleaning liquid device 14 and a waste liquid recovery device 15 arranged inside the chassis 3. Each component of the execution group 7 is connected to each other through a controllable valve 16 to form a passage, and each component is independently connected to the resource group 8. The execution group 7 realizes its own independent operation or coordinated operation through the controllable valve 16.

[0021] The specific implementation process and principle of the present invention are as follows:

[0022] In the present invention, the execution group 7 is composed of 5 relatively independent filter cleaning parts 9, condenser cleaning parts 10, circulation fan cleaning parts 11, space cleaning part one 12, and space cleaning part two 13. After the above components are in a relatively connected state through the controllable valve 16, they are then connected to the cleaning liquid device 14 through the controllable valve 16. The cleaning liquid device 14 can selectively pump the cleaning liquid into any one of the above components, or allow the cleaning liquid to be pumped into all the components in the execution group 7 while also allowing a passage inside them, simplifying the output mode of the cleaning liquid device 14, and at the same time enabling the components of each execution group 7 to work synchronously, maintaining the internal cleaning environment of the indoor unit 2 of the in-row air conditioner as much as possible, so that it can work for a longer time. The waste liquid recovery device 15 can uniformly recover and then uniformly process the waste liquid after the above components are cleaned, effectively improving the waste liquid treatment efficiency.

[0023] Among them, it is particularly necessary to specify the space cleaning part 12 and the space cleaning part 13. The arrangement of the above structure enables them to dynamically clean the space between the filter 4 and the condenser 5 and the space between the condenser 5 and the circulation fan 6. The reason for this setting is that when the in-row air conditioner is operating, at least 70% of the suspended substances or particles are not adsorbed on the internal structure during one cycle and then enter the air again for circulation. After repeated circulation, it causes the internal structure of the in-row air conditioner to become dirty. If this part of the suspended substances can be intercepted during the flow, the cleaning difficulty of the components can be greatly reduced. Therefore, the setting of the space cleaning part 12 and the space cleaning part 13 can effectively extend the existence time of the internal cleaning environment of the indoor unit 2, thereby indirectly extending the operating time of the refrigeration system of the in-row air conditioner, which is very convenient and ingenious.

[0024] Through the setting of the above structure, the maintenance time and maintenance labor cost of the in-row air conditioner for maintenance personnel can be greatly reduced, the operating efficiency of the in-row air conditioner can be improved, and the server room can provide sufficient data service support in a good and stable working environment for a longer time.

[0025] Combined with Figure 1 and Figure 2 As shown, as one of the preferred embodiments of the present invention, the filter cleaning part 9 includes an atomizing nozzle 90 connected to the cleaning liquid device 14, a heater 91 arranged in the spraying direction of the atomizing nozzle 90, and a heat-conducting fin 92 connected to the filter 4 and facing the atomizing nozzle 90. The filter 4 is arranged obliquely toward the side of the atomizing nozzle 90.

[0026] In the present invention, through the action of the heater 91, the cleaning liquid sprayed by the atomizing nozzle 90 becomes hot aerosol, so that it can better come into full contact with the filter 4. Under the action of the heat-conducting fin 92, it condenses into water droplets. The water droplets will dissolve part of the stains and finally fall into the waste liquid recovery device 15 to achieve the cleaning of the filter 4. The inclined arrangement is conducive to the flow of the condensed water and is not easy to accumulate in one place, which is convenient for maintaining a certain cleanliness inside the chassis 3.

[0027] Combined with Figure 1 and Figure 3 As shown, as one of the preferred embodiments of the present invention, the condenser cleaning part 10 includes a high-pressure spray gun 100 connected to the cleaning liquid device 14, a slide rail moving device 101 connected to the high-pressure spray gun 100, a grid-shaped reduction plate 102 fixedly connected below the slide rail moving device 101 and communicating with the waste liquid recovery device 15, and a servo telescopic motor 103 for driving the grid-shaped reduction plate 102 to move in the horizontal direction.

[0028] In the present invention, the high-pressure spray gun 100 moves within a certain track range through the slide rail moving device 101, and can wash most areas of the condenser 5 as much as possible. After a part of the waste liquid flowing down is carried by the grid-shaped reduction tray one 102, it then flows into the waste liquid recovery device 15 below. The grid-shaped reduction tray one 102 is a disc-shaped body with a grid shape and a certain depth, which can carry a part of the liquid and let another part of the liquid flow away along the grid, thus playing a role in controlling the flow rate of the waste liquid, so that it will not all flow downward and cause the waste liquid recovery device 15 to be overloaded. The servo telescopic motor one 101 can control the above structure to extend or retract from the chassis 3, so as to minimize the impact on the fresh air flow when not working.

[0029] Combined with Figure 1 and Figure 4 As shown in the figure, as one of the preferred embodiments of the present invention, the circulating fan cleaning part 11 includes an atomizing nozzle two 110 connected to the cleaning liquid device 14, a grid-shaped reduction tray two 111 arranged below the atomizing nozzle two 110 and communicating with the waste liquid recovery device 15, and a servo telescopic motor two 112 for driving the grid-shaped reduction tray two 111 to move horizontally.

[0030] In the present invention, the atomizing nozzle two 110 can make water or cleaning liquid in a mist form contact with the circulating fan 6 without causing impact. After adhering and condensing into water droplets, they flow downward. After a part of the waste liquid flowing down is carried by the grid-shaped reduction tray two 111, it then flows into the waste liquid recovery device 15 below. The grid-shaped reduction tray two 111 is also a disc-shaped body with a grid shape and a certain depth. The servo telescopic motor two 112 can control the above structure to extend or retract from the chassis 3, so as to minimize the impact on the fresh air flow when not working.

[0031] Combined with Figure 1 and Figure 5 As shown in the figure, as one of the preferred embodiments of the present invention, both the space cleaning part one 12 and the space cleaning part two 13 include a single-axis motor 17 arranged on the inner wall of the chassis 3, a swing arm 18 connected to the output shaft of the single-axis motor 17, a double-axis motor 19 arranged at the free end of the swing arm 18, a movable arm 20 arranged at the output end of the double-axis motor 19, and a receiving groove 21 arranged on one side of the single-axis motor 17 and communicating with the waste liquid recovery device 15 and a spraying head 22 connected to the cleaning liquid device 14. An insulating inner shell 23 and a conductive outer shell 24 are sleeved on the movable arm 20. The conductive outer shell 24 does not contact the movable arm 20, and the conductive outer shell 24 is connected by a line to an electrostatic generator 25 arranged in the chassis 3.

[0032] In the present invention, the structural feature of the space cleaning unit 12 or the space cleaning unit 13 lies in that the movement of the swing arm 18 is controlled by a single-axis motor 17 to enable the overall structure to swing out or retract from the accommodation groove 21, so as to achieve the working state and the storage state. In particular, the storage state can minimize the wind resistance. In the working state, after the swing arm 18 swings out, the output end of the double-axis motor 19 is connected to the movable arm 20. Preferably, the movable arm 20 should be connected to the output end of the double-axis motor 19 through a servo motor. In this way, the servo motor is used to change the attitude of the movable arm 20, and the double-axis motor 19 drives the overall rotation of the movable arm 20, so that the movable arm 20 can continuously perform spatial movement in the space through which the fresh air passes. Based on the above movement mode, in this structure, by using the conductive outer shell 24, it can be charged with a certain intensity of static electricity under the action of the electrostatic generator 25, so as to adsorb the suspended particles in the fresh air, while the insulating inner shell 23 can keep the conductive outer shell 24 in a relatively stable working environment, so that it will not affect the normal operation of other components of the indoor unit 2. After adsorbing the particles, through the single-axis motor 17, the double-axis motor 19 and the movable arm 20, the whole will be stored in the accommodation groove 21. After removing the static electricity, the surface particles are rinsed by the spray head 22 and finally flow into the waste liquid recovery device 15 along the space in the chassis 3.

[0033] Combined with Figure 1 As shown, as one of the preferred embodiments of the present invention, the cleaning liquid device 14 includes an infusion pump 140 connected to the execution group 7 and a cleaning liquid storage box 141 connected to the infusion pump 140. A fresh water storage bin 142 and a cleaning liquid storage bin 143 are arranged in the cleaning liquid storage box 141, and the cleaning liquid storage box 141 is externally arranged on the chassis 3.

[0034] In the present invention, the infusion pump 140 is preferably connected to the fresh water storage bin 142 and the cleaning liquid storage bin 143 respectively through 2 different electromagnetic on-off valves, and the volume of the fresh water storage bin 142 is larger than that of the cleaning liquid storage bin 143. The cleaning liquid storage bin 143 can store water-soluble cleaning liquid or anhydrous cleaning liquid. By controlling the on-off of the electromagnetic on-off valves and the type of cleaning liquid selected, it can be water cleaning, cleaning liquid cleaning or mixed cleaning, which is very convenient and flexible. The externally arranged cleaning liquid storage box 141 is convenient for replenishing liquid without entering the machine room, which is convenient and efficient.

[0035] Combined with Figure 1 As shown, as one of the preferred embodiments of the present invention, the waste liquid recovery device 15 includes a recovery pump 150 connected to the execution group 7 and a waste liquid bucket 151 connected to the recovery pump 150. The waste liquid bucket 151 is externally arranged on the chassis 3.

[0036] In the present invention, the recovery pump 150 is a pump body that pumps waste liquid towards the waste liquid bucket 151, and it needs to communicate with the condensate water tank of the indoor unit 2. Since the grid-shaped reduction plate one 102, the grid-shaped reduction plate two 111, and the accommodation groove 21 all need to communicate with the condensate water tank and then be pumped by the recovery pump 150 into the waste liquid bucket 151 for storage. Preferably, an electric control valve can be provided between the condensate water tank and the recovery pump 150 to control the amount of water entering the waste liquid bucket 151. The externally arranged waste liquid bucket 151 facilitates the drainage of waste liquid without entering the machine room, which is convenient and efficient.

[0037] Combined with Figure 1 As shown, as one of the preferred embodiments of the present invention, the controllable valve 16 includes a circulation on-off valve 160 provided between the actuator groups 7 and a general on-off valve 161 connected between the actuator groups 7 and the resource group 8.

[0038] In the present invention, specifically, the circulation on-off valve 160 is provided between the components of the actuator group 7, referring to between the atomizing nozzle one 90, the high-pressure spray gun 100, the atomizing nozzle two 110, the spray head 22, the infusion pump 140, and the cleaning liquid storage box 141. This enables the cleaning liquid that has not been completely sprayed out during the execution of any actuator component in the actuator group 7 to flow to the actuator component of the next actuator group 7 for spraying. Substantially, it forms a series structure. The advantage of this is that the overall execution integration degree is relatively high and it is easy to control. When separate cleaning is required, the circulation on-off valve 160 between the actuator groups 7 is closed, and the general on-off valve 161 required for the corresponding actuator component is opened. This can save the consumption of cleaning liquid and electrical energy, and the two can be selected according to the situation.

[0039] The beneficial effects of the present invention are as follows: The structure is reliable and reasonable, with self-cleaning ability, providing a good material basis for long-term operation. The internal environment of the equipment is more stable, and it can effectively purify and reuse the self-cleaning structure by itself. Therefore, the maintenance requirements for the in-row air conditioner by maintenance personnel are reduced, which provides favorable support for the long-term stable operation of the server room.

[0040] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
