Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a traction type air conditioning unit. Background Art

[0002] See the attached drawings in the specification Fig.10 , is a schematic diagram of the heat exchange structure of a traditional air conditioner. The traditional air conditioner indoor unit is composed of a motor, a fan 60, a heat exchanger 4, an electric control box, a shell, etc. The main working principle is that under the control of the electric control box, the motor drives the fan 60 to operate, and the operation of the fan 60 drives the air flow to form wind, and the wind is sent into the room after passing through the cold and hot water coolers, thereby realizing cooling or heating the room.

[0003] Traditional air conditioners use fans to supply air and exchange heat, and the noise of air conditioners comes entirely from the noise generated by the operation of the fans. The higher the fan speed, the greater the noise, which greatly affects people's normal work and life comfort.

[0004] At the same time, the air that traditional air conditioners heat through the heat exchanger is a one-time circulating air, that is, the air is returned from the room and then directly sent to the room through the heat exchanger. If the load required by the room is large and the air supply volume is certain, the refrigerant temperature of the heat exchanger must be lowered to meet the room load requirements. Lowering the temperature of the heat exchanger will increase the load of the outdoor unit, thereby increasing energy consumption.

[0005] The fan is driven by an electric motor, which needs to run continuously. Continuous operation places high demands on the motor, resulting in relatively high costs, shortened motor life, and high energy consumption.

[0006] Therefore, the prior art needs to be further developed. Summary of the invention

[0007] The purpose of the present invention is to overcome the above technical deficiencies and provide a traction-type air-conditioning unit to solve the technical problems of high noise and high energy consumption in the air supply form of the traditional air-conditioning indoor unit in the related technology.

[0011] Furthermore, a duct opening for connecting the duct to the air storage chamber is provided at the first end of the duct. The duct opening is provided on the inner wall of the shell. The duct opening is arranged opposite to the air supply port. The air supply port is connected to the air storage chamber through the duct opening.

[0012] Furthermore, the heat exchanger is arranged at the opening of the air duct, and the shape of the heat exchanger matches the shape of the opening of the air duct so as to perform heat exchange on the air flow passing through the opening of the air duct.

[0013] Furthermore, the traction-type air-conditioning unit includes a return air switch component, which is arranged at the return air outlet; the return air switch component has a closed state for blocking the return air outlet and an open state for avoiding the return air outlet. When the wind pressure in the air storage chamber is positive pressure, the return air switch component is in a closed state, and when the wind pressure in the air storage chamber is negative pressure, the return air switch component is in an open state.

[0014] Furthermore, the traction-type air-conditioning unit includes an air supply switch component, which is arranged at the air supply outlet; the air supply switch component has a closed state for blocking the air supply outlet and an open state for avoiding the air supply outlet. When the wind pressure in the air storage chamber is positive pressure, the air supply switch component is in an open state, and when the wind pressure in the air storage chamber is negative pressure, the air supply switch component is in a closed state.

[0015] Furthermore, the return air switch component includes a plurality of louvers, the plurality of louvers are located inside the air duct, and the plurality of louvers are rotatably connected to the outer wall of the shell.

[0016] Furthermore, the air supply switch component includes a plurality of louvers, the plurality of louvers are located outside the shell, and the plurality of louvers are rotatably connected to the outer wall of the shell.

[0017] Furthermore, the shell includes a plurality of shells, and the plurality of shells are together enclosed to form an outer shell.

[0018] Furthermore, the lifting component is movably arranged along the height direction of the shell, and the air storage chamber is located at the bottom of the inner cavity. When the lifting component rises, the wind pressure in the air storage chamber is negative pressure, and when the lifting component descends, the wind pressure in the air storage chamber is positive pressure.

[0019] Furthermore, the traction type air conditioning unit comprises an upper limiter and a lower limiter respectively located at two ends of the shell, the upper limiter is used to limit the lifting component when it rises, and the lower limiter is used to limit the lifting component when it descends.

[0022] Furthermore, the lifting component includes: a lifting plate, the shape of which matches the shape of the shell; and a sealing ring, which is sleeved on the circumference of the lifting plate and abuts against the inner wall of the shell. Beneficial effects: 1. By pulling the lifting component to move in a preset direction within the inner cavity, the air storage cavity can be compressed or the volume of the air storage cavity can be expanded, thereby changing the wind pressure in the air storage cavity and connecting the air storage cavity with the return air port or the air supply port. By setting a heat exchanger, the return air flow or the air supply air flow can be heat exchanged. When the air storage cavity is connected with the return air port, the air flow enters the air storage cavity through the return air port for heat exchange and temporary storage. When the air storage cavity is connected with the air supply port, the air flow that has completed the heat exchange in the air storage cavity is supplied through the air supply port, thereby realizing the heat exchange and air supply functions of the air conditioner.

[0023] 2. Through the above arrangement, the return air outlet is kept away from the supply air outlet, and the supply air outlet and the return air outlet are respectively located at the two ends of the shell. The air flow enters from one end of the shell and is then sent out from the other end of the shell, thereby increasing the air exchange effect inside the room and increasing the air supply efficiency and heat exchange efficiency of the traction air-conditioning unit.

[0024] 3. The traction motor of the present invention only needs to work during the ascending process of the lifting plate, and relies on gravity to achieve operation during the descending process. No traction motor power is required, that is, the traction motor does not need to work, which can save the energy consumption of the motor. The traction motor does not need to work all the time, so the traction motor heat is reduced, the running time is reduced, the motor service life can be increased, the motor development requirements are reduced, the cost is saved, and the energy consumption of the air conditioner is reduced.

[0025] 4. Both the return air flow and the supply air flow can pass through the heat exchanger, so that the supply air and the return air share a heat exchanger, and the air flow undergoes secondary heat exchange, which increases the heat exchange efficiency of the traction air-conditioning unit. Compared with traditional air-conditioning, the refrigerant temperature can be appropriately lowered under the condition of unchanged load, thereby reducing the load of the outdoor unit, achieving energy saving, and solving the technical problem of high energy consumption of air-conditioning units in the prior art.

[0026] 5. The traction air conditioner in the present invention can be set in the middle of the room, or can be set next to the wall, or integrated with the wall, that is, the inside of the wall is hollowed out as the inner cavity, and the wall is used as the shell.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] According to an embodiment of the present invention, a traction air conditioning unit is provided. Figures 1 to 11 , including: a shell 10, an inner cavity 20 is formed inside the shell 10, and a return air port 11 and an air supply port 12 are arranged on the shell 10; a lifting component 2, the lifting component 2 is arranged inside the shell 10 to form an air storage chamber 3 inside the inner cavity 20, and a heat exchanger 4 for heat exchange of air flow is arranged in the air storage chamber 3, and the lifting component 2 is movably arranged in a preset direction in the inner cavity 20 to connect the air storage chamber 3 with the return air port 11 or the air supply port 12 by changing the wind pressure in the air storage chamber 3.

[0032] It should be noted that the heat exchanger 4 adopts the working principle of a conventional air conditioner, and a refrigerant is normally introduced into the heat exchanger 4 , and the airflow can perform heat exchange when passing through the heat exchanger 4 .

[0033] By pulling the lifting component 2 to move in the inner cavity 20 along a preset direction, the air storage chamber 3 can be compressed or the volume of the air storage chamber 3 can be expanded, thereby changing the wind pressure in the air storage chamber 3 and connecting the air storage chamber 3 with the return air port 11 or the air supply port 12. By setting the heat exchanger 4, the return air flow or the air supply air flow can be heat exchanged. When the air storage chamber 3 is connected with the return air port 11, the air flow enters the air storage chamber 3 through the return air port 11 for heat exchange and temporary storage. When the air storage chamber 3 is connected with the air supply port 12, the air flow that has completed the heat exchange in the air storage chamber 3 is supplied through the air supply port 12, thereby realizing the heat exchange and air supply functions of the air conditioner. The fan air supply form is replaced by the traction air supply form, which reduces the running speed of the motor, avoids the noise and energy consumption caused by the continuous operation of the fan driving the fan blades, reduces the running noise of the air conditioner, and solves the technical problems of high noise and high energy consumption in the traditional air supply form of the indoor unit of the air conditioner in the related technology.

[0034] In the traction air conditioning unit of this embodiment, see Figure 1 The shell 10 includes a shell 1, an air supply port 12 and an air return port 11 are respectively arranged at two ends of the shell 1 along a preset direction, and the air supply port 12 is arranged opposite to the air storage chamber 3, wherein the traction air-conditioning unit includes an air duct 13, a first end of the air duct 13 is connected to the air storage chamber 3, and a second end of the air duct 13 is connected to the return air port 11.

[0035] Through the above arrangement, the return air outlet 11 is kept away from the air supply outlet 12, and the air supply outlet 12 and the return air outlet 11 are respectively located at the two ends of the shell 1. The air flow enters from one end of the shell 1 and is then sent out from the other end of the shell 1, thereby increasing the air exchange effect inside the room 30 and increasing the air supply efficiency and heat exchange efficiency of the traction air-conditioning unit.

[0036] In some embodiments, the return air outlet 11 is located at the top of the shell 1, that is, below the ceiling 301, and the supply air outlet 12 is located at the bottom of the shell 1. The shutters 51 of the supply air outlet 12 face into the room 30, so that the air circulates between the ceiling and the floor of the room 30, thereby increasing the air supply efficiency of the traction air-conditioning unit.

[0037] In the traction air conditioning unit of this embodiment, see Figure 1 and Figure 2 The shell 1 is hollow inside, and the air duct 13 is arranged inside the shell 1. Specifically, the air duct 13 is arranged inside the shell 1, which can simplify the structure of the shell 1 and the traction air conditioning unit, reduce the overall thickness of the shell 10, and avoid occupying too much indoor space.

[0038] In the traction air conditioning unit of this embodiment, see Figure 2The first end of the air duct 13 is provided with an air duct opening 14 for communicating the air duct 13 with the air storage chamber 3. The air duct opening 14 is provided on the inner wall 101 of the housing 1. The air duct opening 14 is arranged opposite to the air supply port 12. The air supply port 12 is communicated with the air storage chamber 3 through the air duct opening 14. Through the above arrangement, after the air supply airflow in the air storage chamber 3 enters the air duct opening 14, it passes through a part of the air duct 13 and then is supplied through the air supply port 12, so that the air supply port 12 is communicated with the air storage chamber 3 through a part of the air duct 13, thereby simplifying the air duct structure.

[0039] In the traction air conditioning unit of this embodiment, see Figure 2 The heat exchanger 4 is arranged at the air duct opening 14, and the shape of the heat exchanger 4 matches the shape of the air duct opening 14, so as to perform heat exchange on the airflow passing through the air duct opening 14. Through the above arrangement, both the return airflow and the supply airflow can pass through the heat exchanger 4, so that the supply air and the return air share the same heat exchanger 4, simplifying the structure of the air conditioner. The return airflow 40 in the air duct 13 enters the air storage chamber 3 for temporary storage after passing through the heat exchanger 4 for one heat exchange, and the supply airflow 50 in the air storage chamber 3 passes through the heat exchanger 4 for a second heat exchange and then supplies air through the air supply port 12, so that the airflow undergoes a second heat exchange, increasing the heat exchange efficiency of the traction air conditioning unit. Under the condition of unchanged load, compared with the traditional air conditioner, the refrigerant temperature can be appropriately reduced, thereby reducing the load of the external unit, achieving energy saving, and solving the technical problem of high energy consumption of the air conditioning unit in the prior art.

[0040] It can be understood that by setting the air duct opening 14 and the air duct 13, the air intake and the air supply share a set of air duct openings 14 and the air duct 13, and a heat exchanger 4 is set at the air duct opening 14, so that the function of secondary heat exchange can be achieved. During the return air and air supply process, the air is heat exchanged through the heat exchanger 4. The heat exchange efficiency of the heat exchanger is higher. Under the condition of unchanged load, compared with traditional air conditioners, the refrigerant temperature can be appropriately lowered, thereby reducing the load of the outdoor unit and achieving energy saving.

[0041] In addition, the air supply port 12 is arranged at one end of the air storage chamber 3 and the heat exchanger 4, which can reduce the heat loss of the air supply flow after heat exchange and ensure the heat exchange effect of the air conditioner.

[0042] Specifically, the heat exchanger 4 is located at the bottom of the inner cavity 20 of the outer shell 10, surrounding the entire inner wall 101. That is, when the outer shell is a quadrilateral, the inner walls of the four shells 1 are all equipped with heat exchangers 4. The size of the heat exchanger can be designed according to the load requirements and the size of the inner wall.

[0043] In the traction air conditioning unit of this embodiment, see Figure 1 and Figure 3The traction air conditioning unit includes a return air switch component 5, which is arranged at the return air port 11; the return air switch component 5 has a closed state for blocking the return air port 11 and an open state for avoiding the return air port 11. When the wind pressure in the air storage chamber 3 is positive pressure, the return air switch component 5 is in a closed state, and when the wind pressure in the air storage chamber 3 is negative pressure, the return air switch component 5 is in an open state. Through the above arrangement, the return air port 11 can match the travel state of the lifting component 2. When the wind pressure in the air storage chamber 3 is negative pressure, the return air port 11 is opened, the air supply port 12 is closed, and the return air flow 40 enters the air storage chamber 3 for heat exchange and temporary storage.

[0044] In the traction air conditioning unit of this embodiment, see Figure 2 and Figure 4 The traction air conditioning unit includes an air supply switch component 6, which is arranged at the air supply port 12; the air supply switch component 6 has a closed state for blocking the air supply port 12 and an open state for avoiding the air supply port 12. When the wind pressure in the air storage chamber 3 is positive pressure, the air supply switch component 6 is in the open state, and when the wind pressure in the air storage chamber 3 is negative pressure, the air supply switch component 6 is in the closed state. Through the above arrangement, the air supply port 12 can match the travel state of the lifting component 2. When the wind pressure in the air storage chamber 3 is positive pressure, the air supply port 12 is opened, the return air port 11 is closed, and the air supply airflow 50 leaves the air storage chamber 3 for air supply.

[0045] In the traction air conditioning unit of this embodiment, see Figure 1 and Figure 3 The return air switch component 5 includes a plurality of shutters 51, which are located inside the air duct 13, and are all rotatably connected to the outer wall 102 of the housing 1. Specifically, the return air switch component 5 is a shutter-type air outlet, which is fixed on the outer wall inside the air duct 13, and the rotation direction of the plurality of shutters 51 is toward the inside of the air duct 13. When the air storage chamber 3 is under negative pressure, the air duct 13 is also under negative pressure, and the shutters 51 of the return air switch component 5 are driven by the external airflow to rotate, so that the return air outlet 11 is opened. When the air storage chamber 3 is under positive pressure, the air duct 13 is also under positive pressure, and the shutters 51 of the return air switch component 5 rotate under the action of gravity and positive pressure, so that the return air outlet 11 is closed, thereby realizing that the return air outlet 11 can be automatically opened or closed according to the wind pressure.

[0046] Specifically, see Figure 3 The shutter 51 is installed on the outer wall 102 through a rotating shaft, and bearings 512 are fixed at both ends of the rotating shaft 511.

[0047] In some embodiments, a filter component is provided at the return air port 11 for filtering the return air flow and filtering out dust and impurities in the air, thereby improving the cleanliness of the air flow entering the air storage chamber 3 .

[0048] In the traction air conditioning unit of this embodiment, see Figure 2 and Figure 4 The air supply switch component 6 includes a plurality of shutters 51, which are located outside the housing 1, and are all rotatably connected to the outer wall 102 of the housing 1. Specifically, the air supply switch component 6 is a shutter-type air outlet, which is installed on the outer wall located outside the housing 1, and the rotation direction of the plurality of shutters 51 is toward the outside of the housing 1. When the air storage chamber 3 is under positive pressure, the shutters 51 of the air supply switch component 6 are pushed by the air supply airflow 50 of the air storage chamber 3 to rotate, so that the air supply outlet 12 is opened. When the air storage chamber 3 is under negative pressure, the shutters 51 of the air supply switch component 6 rotate under the action of gravity and negative pressure, so that the air supply outlet 12 is closed, thereby realizing that the air supply outlet 12 can be automatically opened or closed according to the wind pressure.

[0049] Specifically, see Figure 4 The shutter 51 is installed on the outer wall 102 through a rotating shaft, and bearings are fixed at both ends of the rotating shaft.

[0050] In the traction air conditioning unit of this embodiment, see Figure 1 The shell 1 includes multiple shells, and the multiple shells 1 together form an outer shell 10.

[0051] It can be understood that each shell 1 is provided with structures such as return air outlet 11, supply air outlet 12 and air duct 13. When the lifting component 2 is lifted or lowered, it can drive the air outlets or air ducts on all shells 1 to work at the same time, thereby improving the air supply efficiency of the traction air-conditioning unit.

[0052] Specifically, the overall shape of the outer shell 10 can be designed to be circular, quadrilateral or polygonal. The traction air conditioner in the present invention can be set in the middle of the room, or can be set next to the wall, or can be integrated with the wall, that is, the inside of the wall is hollowed out as the inner cavity 20, and the wall is used as the shell 1. The traction air-conditioning unit in the present invention has high flexibility and can hide the overall structure in the room 30, with high aesthetics.

[0053] In some embodiments, see Fig.11 , Fig.11 1 is a top view of the housing 10 when the overall shape of the housing 10 is a quadrilateral. When the housing 10 is a quadrilateral, it includes four shells 1 , and the four shells 1 are mutually enclosed to form the housing 10 .

[0054] In some embodiments, when the traction air-conditioning unit is integrated with a wall, or replaces the wall as a part of the room, sound insulation cotton can be laid on the shell 1 to further reduce the noise of the air-conditioning operation.

[0055] In the traction air conditioning unit of this embodiment, see Figure 1The lifting component 2 is movably arranged along the height direction of the housing 10, and the air storage chamber 3 is located at the bottom of the inner chamber 20. When the lifting component 2 rises, the wind pressure in the air storage chamber 3 is negative pressure, and when the lifting component 2 falls, the wind pressure in the air storage chamber 3 is positive pressure. Through the above arrangement, the lifting component 2 moves along the height direction of the housing 10.

[0056] It can be understood that the traction motor 82 of the present invention only needs to work during the ascending process of the lifting plate 21, and operates by gravity during the descending process, and does not require the power of the traction motor 82, that is, the traction motor 82 does not need to work, which can save the energy consumption of the motor. The traction motor 82 does not need to work all the time, so the heat generation of the traction motor 82 is reduced, the operating time is reduced, the service life of the motor can be increased, the motor development requirements are reduced, the cost is saved, and the energy consumption of the air conditioner is reduced.

[0057] In the traction air conditioning unit of this embodiment, see Figure 1 The traction air conditioning unit includes an upper limiter 71 and a lower limiter 72 respectively located at both ends of the housing 1. The upper limiter 71 is used to limit the lifting component 2 when it rises, and the lower limiter 72 is used to limit the lifting component 2 when it descends. Specifically, the upper limiter 71 and the lower limiter 72 are respectively fixed to the inner wall 101. When the lifting component 2 reaches the upper limiter 71, the traction motor 82 stops working. When the lifting component 2 reaches the lower limiter 72, the traction motor 82 starts working.

[0058] In the traction air conditioning unit of this embodiment, see Figure 7 The traction air-conditioning unit includes: a traction wheel 81, which is located on the side of the lifting component 2 away from the air storage chamber 3, and the traction wheel 81 is rotatably arranged. A traction rope is wound around the traction wheel 81, and the traction rope is fixedly connected to the lifting component 2; a traction motor 82, and the traction motor 82 is drivingly connected to the traction wheel 81.

[0059] In some embodiments, a traction drive mechanism such as a traction motor 82 and a traction wheel 81 can be installed on the ceiling 301 of the room 30, and a bearing bracket supports one end of the drive shaft 84 to ensure the balance and stability of the drive shaft 84. A traction wheel 81 is fixed on the drive shaft 84, and the traction wheel 81 is connected to a traction rope 85, and the other end of the traction rope 85 is connected to the lifting plate 21, wherein the size of the traction wheel 81 can be designed according to the actual size of the ceiling space, and the larger the traction wheel 81, the faster the lifting plate 21 rises, and the speed of the synchronous traction motor 82 can be appropriately reduced.

[0060] In the traction air conditioning unit of this embodiment, see Figure 7 The traction air conditioning unit includes an energy storage device 83, which is electrically connected to the rotor of the traction motor 82 so that the energy storage device 83 can recover electrical energy.

[0061] Specifically, during the descent of the lifting plate 21, the traction rope 85 is driven downward, and the traction rope 85 drives the traction wheel 81 to rotate, which directly drives the drive shaft 84 to rotate. The drive shaft 84 extends from the rotor of the traction motor 82, that is, the drive shaft 84 and the rotor of the traction motor 82 are the same component, which synchronously drives the rotor of the traction motor 82 to rotate. The rotation of the rotor of the traction motor 82 generates voltage (generator principle). An energy storage device 83 is added at the end of the traction motor 82 to achieve energy recovery.

[0062] It can be understood that by reverse charging the traction motor 82 and recycling energy, the energy consumption of the traction air-conditioning unit is further reduced.

[0063] Specifically, it also includes an electric control box, and the electric control box 86 is electrically connected to the traction motor 82 and the energy storage device 83 respectively, so as to perform real-time control.

[0064] In the traction air conditioning unit of this embodiment, see Figure 7-8 The lifting component 2 includes: a lifting plate 21, the shape of the lifting plate 21 matches the shape of the housing 10; a sealing ring 22, the sealing ring 22 is sleeved on the circumference of the lifting plate 21, and the sealing ring 22 abuts against the inner wall 101 of the housing 10.

[0065] Specifically, the shape of the lifting plate 21 matches the shape of the outer shell 10 and is slightly smaller than the inner wall size of the outer shell 10. The sealing ring 22 is sleeved on the circumferential side of the lifting plate 21. The sealing ring 22 abuts against the inner wall 101 of the outer shell 10. The sealing ring 22 is elastic, thereby playing a sealing role, separating the air storage chamber 3 from the space above the lifting plate 21, thereby preventing the lifting plate 21 from leaking and affecting the air supply efficiency of the air conditioner.

[0066] In the traction air conditioning unit of this embodiment, see Figure 7-8 The lifting component 2 includes a counterweight block 23, and the counterweight block 23 is fixedly connected to the lifting plate 21.

[0067] Specifically, a counterweight block 23 is fixed to the lifting platform 21, and the counterweight block 23 is used to increase the weight of the lifting platform 21. In the absence of the traction motor 82 driving, the lifting platform 21 can freely drop under the action of gravity.

[0068] Specifically, a lubricating oil layer 25 is also included on the sealing ring 22, so as to reduce the friction between the sealing ring 22 and the inner wall 101. The lubricating oil plays a role of sealing and lubrication, and when the lifting plate 21 moves up and down, smooth operation and good sealing are guaranteed.

[0069] In some embodiments, see Fig. 9A single traction motor can be used to control multiple air conditioners, and a set of traction drive components can be used to jointly drive multiple lifting plates 21, that is, a one-to-many traction air conditioner unit is used, thereby simplifying the equipment cost and improving the energy consumption utilization rate of the equipment.

[0070] It is understandable that the noise of traditional air conditioners is the noise generated by the rotation of the fan. The higher the fan speed, the greater the noise. In the traction air conditioner unit of this embodiment, the positive and negative pressure differences generated by the operation of the lifting plate 21 form wind. The running noise of the traction motor 82 itself is very low, generally around 20 decibels. The friction noise between the lifting plate 21 and the inner wall 101 is very small under the action of lubricating oil, generally around 20-30 decibels. The better the lubrication effect, the smaller the noise. The noise of traditional air conditioners is generally above 30-50 decibels. The greater the air volume, the greater the noise. The overall noise of the air conditioner in the present invention is basically below 30 decibels.

[0071] Calculated based on a floor height of 3 meters, the effective operating height of the lifting plate 21 is 2.5 meters. The air conditioner of the present invention is calculated as a square shape with a side length of 1 meter. Each time the lifting plate 21 completes an ascent and descent, that is, completes a stroke, the air supply volume is about 2.5m³. Assuming a stroke of 5 seconds, the air supply volume per hour is 2.5*3600 / 5=1800m³. It only occupies 1㎡ of space, and each stroke takes 5 seconds to achieve an air volume of 1800m³ / hour. If the stroke time is reduced, a larger air volume will be generated. The actual time used for each stroke of the lifting plate is designed according to the actual size, the number of air conditioners configured, the load demand, the air supply speed, etc.

[0072] The working process of the traction rope air conditioning unit in this embodiment is as follows: See also Figure 5 When the air conditioner is turned on, the traction motor 82 starts, the traction motor 82 drives the traction wheel 81 to rotate, and the traction rope 85 runs upward, pulling the lifting plate 21 to run upward. Because the air storage chambers 3 at the upper and lower parts of the lifting plate 21 are separated by the lifting plate 21, when running upward, the air storage chamber 3 at the lower side of the lifting plate 21 is negative pressure, because the air duct 13 is connected to the lower side of the lifting plate 21, the air duct 13 is also negative pressure, at this time, the shutter 51 of the air supply switch component 6 blocks the air supply port 12 at the air supply switch component 6 under the action of gravity and negative pressure, and the shutter 51 of the return air switch component 5 opens under the action of negative pressure, and the air enters the air duct 13 from the return air port 11 of the return air switch component 5, and then passes through the heat exchanger 4 for heat exchange, and enters the air storage chamber 3 below the lifting plate 21. When the lifting plate 21 rises to the position of the upper limiter 71, the traction motor 82 stops working, and the lifting plate 21 starts to run downward under the action of gravity.

[0073] See also Figure 6When the lifting plate 21 moves downward, the air storage chamber 3 below the lifting plate 21 is at positive pressure, and the air duct 13 is at positive pressure. At this time, the shutter 51 of the return air switch component 5 blocks the return air port 11 of the return air switch component 5 under the action of gravity and positive pressure, and the shutter 51 of the air supply switch component 6 opens under the action of positive pressure. The air in the air storage chamber 3 below the lifting plate 21 passes through the heat exchanger 4 and is sent from the air supply switch component 6 to the room 30. When the lifting plate 21 descends to the position of the lower limiter 72, the traction motor 82 starts to drive the lifting plate 21 to move upward.

[0074] The above actions are repeated for one air conditioning cycle, thus realizing the air supply and heat exchange function of the air conditioning.

[0075] In the traction air-conditioning unit of the present embodiment, the fan air supply form is replaced by the traction air supply form, which reduces the air-conditioning noise, reduces the motor running speed and running time, effectively reduces the air-conditioning energy consumption, extends the motor life, and through the reverse charging of the motor, energy is recycled and utilized, and the heat exchange efficiency is improved through secondary heat exchange through the heat exchanger 4. At the same time, the refrigerant temperature of the heat exchanger can be increased, the load of the external unit can be reduced, and energy saving can be achieved.
