Split-type energy-saving air conditioners mainly consist of an indoor unit and an outdoor unit.

The drive mechanism rotates the turntable to adjust the angle of the indoor unit. When the position of the indoor unit needs to be adjusted during maintenance, the drive device rotates the turntable, which in turn drives the indoor unit, which is fixed by a fixing mechanism, to rotate synchronously, thereby adjusting the angle of the indoor unit. An airbag assembly is provided on the outer circumference of the turntable, and the airbag assembly is equipped with air jet nozzles. When the turntable rotates, the turntable drives the air jet nozzles through the airbag assembly to clean the indoor unit. The nozzles clean the area of ​​the indoor unit after rotation, thereby ensuring the cleanliness of the indoor unit surface and improving the convenience and cleanliness of maintenance.

[0022] 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.

[0023] When repairing an air conditioner indoor unit, two methods are commonly used. The first method involves keeping the indoor unit mounted on the wall and having the repairman use a ladder or chair to align himself with the unit for repair. The second method involves removing the indoor unit from the wall and placing it on the ground for repair.

[0024] The first method involves repair personnel using ladders or other tools, which puts them in mid-air, making it difficult to change or retrieve tools and posing a safety risk. The second method requires repair personnel to frequently move the indoor unit for repositioning, resulting in high labor intensity. Both methods are time-consuming and labor-intensive, leading to low efficiency in air conditioner repair.

[0025] like Figures 1 to 11 As shown, an energy-saving air conditioner and its maintenance platform include: like Figure 1 An energy-saving air conditioner includes: a compressor, a condenser, a throttling valve, a heat exchanger, a dry cooler, and a bypass valve connected together; the compressor, condenser, throttling valve, and heat exchanger are connected in sequence and cyclically; the heat exchanger is connected to the dry cooler and the bypass valve respectively, and the dry cooler and the bypass valve are connected to each other; Specifically, the system connects to the heat exchanger via a dry cooler and a bypass valve, thereby enabling switching between mechanical refrigeration mode, natural cold source mode, and hybrid mode.

[0026] In this embodiment, the compressor is a magnetic levitation centrifugal compressor; Specifically, the magnetic levitation centrifugal compressor uses variable frequency soft start technology, which has an extremely low starting current, minimal impact on the power grid, and allows more equipment to start simultaneously. At the same time, because there is no problem of reduced heat exchange efficiency due to oil contamination, the cooling capacity does not decrease during long-term operation and can maintain a continuous and stable cooling capacity.

[0027] In this embodiment, the heat exchanger uses small-diameter copper tubes; Specifically, small-diameter copper tubes can significantly increase the heat exchange area per unit volume and improve efficiency. By adopting a 5mm copper tube solution, the overall cost can be reduced by about 6%, and the refrigerant consumption can be reduced by up to 26%.

[0028] In this embodiment, the throttle valve is an electronic expansion valve; Specifically, it can adjust the refrigerant flow in real time and accurately according to the air conditioner's operating status, thereby achieving the best energy-saving effect and temperature control accuracy.

[0029] Figure 1This is a schematic diagram of the energy-saving air conditioner frame of the present invention. The diagram illustrates the main components of the energy-saving air conditioner. In mechanical refrigeration mode, the compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas. The high-temperature, high-pressure refrigerant gas enters the outdoor condenser and releases a large amount of heat to the outdoor air. After becoming a high-pressure liquid, it enters the expansion valve. The expansion valve cools and depressurizes the refrigerant, turning it into a low-temperature, low-pressure liquid refrigerant. The low-temperature, low-pressure liquid refrigerant enters the indoor evaporator. The indoor hot air passes through the evaporator, and the refrigerant inside the evaporator absorbs heat from the air, evaporating from liquid to gas, thereby carrying away the heat from the room and making the blown air colder. After the evaporated low-temperature, low-pressure gaseous refrigerant passes through the gas-liquid separator to remove the internal liquid refrigerant, it will be sucked back into the compressor. At this time, chilled water flows directly into the heat exchanger through the bypass valve, exchanges heat with the refrigerant in the heat exchanger, and then flows out. In natural cooling mode, the high-energy-consuming compressor is turned off. At this time, the chilled water flows out through the dry cooler. The dry cooler dissipates the heat carried by the chilled water to the outside. After cooling down, it re-enters the heat exchanger to exchange heat with the refrigerant. Hybrid mode: The compressor operates for mechanical refrigeration. At this time, the chilled water is pre-cooled by the dry cooler. After the return water is pre-cooled, it flows into the heat exchanger for further cooling, thereby reducing the power of the compressor and reducing losses.

[0030] like Figures 2 to 11 As shown, an energy-saving air conditioner repair platform includes: a lifting platform 1, a turntable 2, a fixing mechanism 3, a drive device 4, an airbag assembly 5, and a jet nozzle 6; the lifting platform 1 has an adjustment cavity 11, the turntable 2 is installed in the adjustment cavity 11, the turntable 2 has a fixing cavity 21, the fixing mechanism 3 is installed in the fixing cavity 21, the fixing mechanism 3 is used to fix the indoor unit, the drive device 4 is provided below the turntable 2, the drive device 4 is used to drive the turntable 2 to rotate and adjust the angle of the indoor unit, the airbag assembly 5 is provided on the outer circumference of the turntable 2, the airbag assembly 5 is provided with a jet nozzle 6, when the turntable 2 rotates, the turntable 2 drives the jet nozzle 6 to spray air to clean the indoor unit through the airbag assembly 5; Specifically, the lifting platform 1 has an adjustment cavity 11. The lifting platform 1 adjusts its height via an electric push rod to accommodate maintenance personnel of different heights. The lifting platform 1 consists of a base plate, an electric push rod, and a platform. The electric push rod is fixedly installed between the base plate and the platform. The lifting platform 1 adjusts its height by sliding the platform using the electric push rod. Simultaneously, casters (not shown in the figure) are installed on the base plate to move the lifting platform 1. Furthermore, a magnetic plate can be installed on the outside of the adjustment cavity 11 of the lifting platform 1 to magnetically attract screws, metal clips, and other parts during the disassembly of the indoor unit, thus securing the parts to the lifting platform 1 and preventing loss. A turntable 2 is installed inside the adjustment cavity 11, and a fixing cavity 21 is provided on the turntable 21. A fixing mechanism 3 is installed inside the fixing cavity 21 to fix the indoor unit. The fixing mechanism 3 is used to fix indoor units of different horsepower, ensuring the stability of the air conditioner indoor unit during maintenance and facilitating disassembly. By fixing indoor units of different horsepower, the lifting platform 1 can achieve the desired height adjustment. The high-performance maintenance platform features a drive unit 4 located beneath the turntable 2. This drive unit 4 rotates the turntable 2 to adjust the indoor unit's angle. During maintenance, when the indoor unit's position needs adjustment, the drive unit 4 rotates the turntable 2, which in turn rotates the indoor unit, which is fixed by the fixing mechanism 3. This allows for angle adjustment, avoiding frequent position adjustments or moving of the indoor unit by maintenance personnel, reducing workload and improving efficiency. An airbag assembly 5 is located on the outer circumference of the turntable 2, with air nozzles 6 mounted on it. When the turntable 2 rotates, the airbag assembly 5 drives the air nozzles 6 to clean the indoor unit. Similarly, when the drive unit 4 rotates the turntable 2, the airbag assembly 5 drives the nozzles to clean the area after the indoor unit has rotated, ensuring the cleanliness of the indoor unit's surface. This enhances the convenience and cleanliness of maintenance. After the indoor unit is removed and placed on the turntable 2, secured by the fixing mechanism 3, multiple rotations of the turntable 2 are used to initially clean the dust before further maintenance.

[0031] In this embodiment, the fixing mechanism 3 includes a fixed motor 31, a driving gear 32, a driven rack 33, and a fixing plate 34. The fixed motor 31 is installed in the fixing cavity 21, and the driving gear 32 is fixedly installed on the fixed motor 31. The driving gear 32 is rotatably installed in the fixing cavity 21, and driven racks 33 are obliquely symmetrically arranged on both sides of the driving gear 32. The driven rack 33 has a broken line structure 331, and the fixing plate 34 is fixedly installed on the driven rack 33. The fixing plate 34 is slidably installed on the turntable 2. The turntable 2 is provided with lifting protrusions 22. Specifically, when placing the indoor unit, the maintenance personnel align it with the lifting protrusion 22, creating a gap between the bottom of the indoor unit and the surface of the turntable 2. This facilitates the disassembly of the indoor unit's casing, improving maintenance efficiency. After the indoor unit is placed, the personnel start the fixing motor 31. The fixing motor 31 rotates forward, driving the drive gear 32 to rotate. When the drive gear 32 rotates, it drives two driven racks 33 to slide in the center. The driven racks 33 drive the fixing plate 34 to move synchronously. The fixing plate 34 fixes both sides of the indoor unit, thus completing the fixing of the indoor unit. Preferably, the fixing plate 34 is equipped with a pressure sensor, and the fixing effect of the indoor unit is determined by monitoring the data from the pressure sensor.

[0032] In this embodiment, the driving device 4 includes a rotary motor 41, a driving gear 42, and a driving gear ring 43; the rotary motor 41 is fixedly connected to the lifting platform 1, and the output end of the rotary motor 41 extends into the adjustment cavity 11 and is fixedly connected to the driving gear 42; the driving gear 42 is rotatably mounted in the adjustment cavity 11, and a driving gear ring 43 is provided on one side of the driving gear 42; the driving gear ring 43 is coaxially mounted with the lifting platform 1, and the driving gear ring 43 is fixedly mounted with the turntable 2; Specifically, when the indoor unit needs to be rotated, the rotary motor 41 starts and drives the drive gear 42 to rotate synchronously. The drive gear 42 drives the drive gear ring 43 to rotate synchronously. The drive gear ring 43 drives the turntable 2 to rotate. The rotation drives the fixed mechanism 3 installed on it and the indoor unit to rotate synchronously, so that the area to be repaired faces the repair personnel.

[0033] In this embodiment, the airbag assembly 5 includes a compression cam 51, a compression plate 52, a compression airbag 53, an air outlet valve 54, an air inlet valve 55, an air intake nozzle 56, and a collection box 57. The compression cam 51 is located in the adjustment cavity 11 and is fixedly connected to the turntable 2. The compression plate 52 is provided on the outer circumference of the compression cam 51. The compression plate 52 is slidably installed in the adjustment cavity 11. The compression plate 52 is provided with a compression arc surface 521 that cooperates with the compression cam 51. A reset point is provided on the compression arc surface 521. The inclined surface 522 has a compression airbag 53 on the outer circumference of the compression plate 52. The compression airbag 53 is slidably installed in the adjustment cavity 11. An air outlet valve 54 and an air inlet valve 55 are respectively installed at both ends of the compression airbag 53. The air outlet valve 54 and the air inlet valve 55 extend through the adjustment cavity 11. The air outlet valve 54 is fixedly installed with the jet nozzle 6, and the air inlet valve 55 is fixedly connected with the suction nozzle 56. The suction nozzle 56 is located in the collection box 57, and the collection box 57 is fixedly installed on the lifting platform 1. Specifically, the extrusion cam 51 is located in the adjustment cavity 11 and is fixedly connected to the turntable 2; an extrusion plate 52 is provided on the outer circumference of the extrusion cam 51; the extrusion plate 52 is slidably installed in the adjustment cavity 11, and an extrusion arc surface 521 that cooperates with the extrusion cam 51 is provided on the extrusion plate 52; an extrusion air bladder 53 is provided on the outer circumference of the extrusion plate 52. When the turntable 2 rotates, it drives the extrusion cam 51 to rotate synchronously. The protrusion of the extrusion cam 51 slides along the extrusion arc surface 521 of the extrusion plate 52, and the thickness of the extrusion plate 52 gradually increases along the arc surface, thereby gradually reducing the gap between the extrusion plate 52 and the extrusion cam 51. In turn, the protrusion pushes the extrusion plate 52 along the direction of the extrusion air bladder 53. The sliding distance gradually increases; a reset slope 522 is provided on the extrusion arc surface 521. The reset slope 522 is used to reset the extrusion cam. When the rotation distance of the extrusion cam 51 exceeds the extrusion arc surface 521 of the extrusion plate 52, the extrusion cam 51 can be rotated to continue rotating forward to adjust to the required angle, or the extrusion cam 51 can be reversed. The extrusion cam 51 pushes the extrusion plate 52 to slide through the reset slope 522, thereby realizing the reverse angle adjustment. The extrusion airbag 53 is slidably installed in the adjustment cavity 11. An air outlet valve 54 and an air inlet valve 55 are respectively installed at both ends of the extrusion airbag 53. The air outlet valve 54 and the air inlet valve 55 extend through the adjustment cavity 11. The air outlet valve 54 and the air inlet valve 55 are connected to the air jet. The nozzle 6 is fixedly installed. After the compression airbag 53 is compressed, the gas inside the compression airbag 53 can only be ejected through the exhaust valve 54 and the jet nozzle 6. The curvature of the compression airbag is at least the same as the angle of rotation of the entire indoor unit through the jet nozzle; thereby cleaning the dust on the indoor unit, reducing dust during maintenance, ensuring the breathing safety of maintenance personnel, and at the same time, removing dust from the indoor unit facilitates subsequent disassembly and maintenance. The intake valve 55 is fixedly connected to the suction nozzle 56; the suction nozzle 56 is located in the collection box 57, which is fixedly installed on the lifting platform 1. When the compression cam 51 rotates clockwise to the top of the compression arc surface 521 of the compression plate 52, the rotating electric... When the machine 41 reverses and drives the turntable 2 to reverse, the extrusion cam 51 no longer extrudes and pushes the extrusion plate 52, the pressure on the extrusion airbag 53 decreases, and outside air enters the extrusion airbag 53 through the intake nozzle 56 along the intake valve 55. The extrusion airbag 53 inflates and resets, pushing the extrusion plate 52 to reset. At the same time, the intake nozzle 56 sucks the dust blown off by the air jet nozzle 6 into the collection box 57, ensuring the cleanliness of the turntable 2 surface, ensuring the comfort of maintenance, and realizing the unification of the maintenance area and the cleaning area. When performing maintenance on this area, it is first cleaned through the air jet nozzle 6 to ensure the cleanliness of the area, thereby improving the comfort and convenience of maintenance and improving maintenance efficiency.

[0034] In this embodiment, the collection box 57 includes a box body 571 and a filter bag 572; the box body 571 is fixedly installed on the lifting platform 1, and the box body 571 is provided with an air suction nozzle 56; the filter bag 572 is provided in the direction of the air suction nozzle 56; the filter bag 572 is detachably connected to the box body 571. Specifically, the housing 571 protects the suction nozzle 56 and has a detachable filter bag 572 installed on it. When the suction nozzle 56 sucks in air, it draws the dust on the turntable 2 into the filter bag 572 for collection, thereby ensuring the cleanliness of the surface of the turntable 2. At the same time, the filter bag 572 is replaced after maintenance.

[0035] In this embodiment, a guide plate 5711 is provided on the housing 571; Specifically, the guide plate 5711 is tangent to the filter bag 572. The guide plate 5711 is used to guide the airflow when the suction nozzle 56 draws air, thereby guiding the dust to drift and making it easier for the dust to enter the filter bag 572, improving the dust collection efficiency and ensuring the collection quality.

[0036] When using an energy-saving air conditioner repair platform, the repair personnel place the indoor unit by aligning it with the lifting protrusion 22, and then start the fixing motor 31. The fixing motor 31 rotates forward, which in turn drives the drive gear 32 to rotate. When the drive gear 32 rotates, it drives two driven racks 33 to slide in the middle. The driven racks 33 drive the fixing plate 34 to move synchronously. The fixing plate 34 fixes the two sides of the indoor unit, thereby completing the fixing of the indoor unit. After the indoor unit is fixed, the operator first starts the rotary motor 41 to rotate forward. The rotary motor 41 drives the drive gear 42 to rotate synchronously, which in turn drives the drive gear ring 43 to rotate synchronously. The drive gear ring 43 drives the turntable 2 to rotate, and the turntable 2 drives the indoor unit to rotate along the direction of the jet nozzle 6. At this time, the compression cam 51 rotates synchronously with the turntable 2. The compression cam 51 pushes the compression plate 52 to slide along the direction of the compression airbag 53. The compressed gas inside the compression airbag 53 flows through the air outlet valve 54 and is ejected from the jet nozzle 6. The jet ejected sprays air onto the indoor unit. Cleaning: After the indoor unit has completely passed the jet nozzle 6, the rotary motor 41 reverses, the turntable 2 reverses, and the squeezing cam 51 reverses. The squeezing cam 51 no longer pushes the squeezing plate 52, and the squeezing plate 52 no longer presses the squeezing airbag 53. The suction nozzle 56 draws in air and discharges the air into the squeezing airbag 53 through the air intake valve 55. The squeezing airbag 53 draws in air and pushes the squeezing plate 52 back to its original position. At the same time, the suction nozzle 56 draws the dust on the turntable 2 into the collection box 57. After repeating the above process multiple times to remove most of the dust on the indoor unit, the turntable 2 returns to the center position for maintenance. When the position of the indoor unit needs to be adjusted during maintenance, the rotary motor 41 rotates the turntable 2 to make the adjustment. At the same time, the jet nozzle 6 sprays gas to blow away the parts that need to be repaired and remove residual dust.
