Description

Technical Field

[0001] This application relates to the technical field of heat pump systems, and in particular to an air conditioning heat pump system based on a dynamic landscape water system. Background Technology

[0002] With the development of modern commercial real estate, high-end hotels, and large public buildings, large-scale outdoor landscape water features (such as waterfalls, fountains, and cascades) have become a standard feature for enhancing the ecological value and aesthetics of buildings. Simultaneously, these buildings typically have independent large-scale central air conditioning (heat pump) systems to meet indoor heating and cooling needs. However, existing systems have the following significant drawbacks in practical engineering applications:

[0003] Energy isolating itself leads to double waste: traditional landscape water systems are only used for ornamental purposes, and their water pumps consume a lot of electricity while running around the clock without generating any additional energy benefits; while traditional air conditioning systems (such as air-cooled heat pumps or cooling tower water-cooled units) consume huge amounts of electricity when dissipating heat in summer, and the cooling towers occupy a large area, have high operating noise, and easily generate a lot of water mist, which seriously damages the overall landscape design of the building.

[0004] Traditional air conditioners have extremely low energy efficiency under extreme conditions: In the extreme cold of winter or the extreme heat of summer, the large temperature difference between the outdoor air and the traditional air source heat pump can cause abnormal condensing or evaporating pressures, resulting in a sharp decline in the unit's coefficient of performance (COP) and even frequent shutdowns. Furthermore, in the core areas of modern large buildings or data centers, there is still a significant demand for cooling in winter. Forcing traditional systems to operate with compressors during winter can easily lead to equipment failure and result in persistently high energy consumption. Summary of the Invention

[0005] In order to achieve a three-in-one integration of "landscape appreciation + energy utilization + energy conservation and consumption reduction" and realize a win-win situation for environmental protection and economy, this application provides an air conditioning heat pump system based on dynamic landscape water system.

[0006] This application provides an air conditioning heat pump system based on a dynamic landscape water system, which adopts the following technical solution:

[0007] An air conditioning heat pump system based on a dynamic landscape water system includes:

[0008] A dynamic landscape water system module, comprising an outdoor landscape pool, wherein the landscape pool is equipped with a landscape release end;

[0009] The heat pump main unit module is located in an outdoor machine room. The heat pump main unit module includes an evaporator, a condenser, a compressor, and a throttling device, which together form a heat pump circulation loop.

[0010] An indoor terminal module, comprising air conditioning heating and cooling terminals installed in an indoor building;

[0011] A water-heat exchange circuit includes an intermediate heat exchanger, which is located in the machine room. A first water circuit is provided between the intermediate heat exchanger and the dynamic landscape water system module. A second water circuit is provided between the intermediate heat exchanger and the heat pump host module. A third water circuit is provided between the intermediate heat exchanger and the indoor terminal module.

[0012] The intelligent control module includes multiple sensors and a controller. The sensors are respectively installed on the landscape water pool, the heat pump main unit module, the indoor terminal module, and the water-heat exchange circuit to collect the operating parameters of each module. The controller is electrically connected to the dynamic landscape water system module, the heat pump main unit module, the indoor terminal module, and the sensors to control the coordinated operation of each module based on the parameters collected by the sensors.

[0013] By adopting the above technical solutions, the energy island of traditional air conditioning systems and landscape water systems operating independently is broken. The landscape pool and the water flow of the landscaping are used as natural cooling towers or low-temperature heat sources for the heat pump system. The source-side decoupling of the water system is achieved by using an intermediate heat exchanger. While eliminating the defects of traditional cooling towers such as large footprint, high noise, and damage to appearance, the kinetic energy released at the landscaping end is reused, the overall energy efficiency ratio of the system is improved, and intelligent synergy between landscape viewing and energy saving is achieved.

[0014] Optionally, the first water circuit is an outdoor landscape heat absorption and exhaust circuit. A first water pump is installed in the landscape pool. The first water circuit is sequentially fluidly connected to the landscape pool, the first water pump, the primary side of the intermediate heat exchanger, and the landscape release end, and finally flows back to the landscape pool, forming an open circulating medium link.

[0015] By adopting the above technical solution, an open outdoor landscape heat absorption and exhaust circuit is constructed. During summer cooling, the release end of the landscape (such as waterfalls and fountains) achieves efficient evaporative cooling and heat dissipation through large-area contact between water flow and outdoor air. During winter heating, the huge sensible and latent heat of the landscape water body is used as a stable heat source, making full use of the natural heat capacity of the water body and the dynamic water vapor exchange during the landscape construction process, which greatly improves the heat exchange efficiency.

[0016] Optionally, the second water circuit is a source-side transport circuit of the main unit. A second water pump is provided between the intermediate heat exchanger and the heat pump main unit module. The second water circuit is sequentially fluidly connected to the source water outlet of the heat pump main unit module, the second water pump, the secondary side of the intermediate heat exchanger, and the source water inlet of the heat pump main unit module, forming a first closed-loop circulation medium link.

[0017] By adopting the above technical solution, a first closed-loop circulation medium link is constructed on the source side of the main unit. Since outdoor landscape water usually contains impurities such as mud, sand, and algae, the dirty water (first water circuit) and clean water (second water circuit) are physically isolated through the intermediate heat exchanger, which ensures the cleanliness of the condenser / evaporator pipeline inside the heat pump main unit module, avoids scaling and corrosion of core high-value equipment, and extends the service life of the heat pump main unit module.

[0018] Optionally, the third water circuit is an indoor terminal heating and cooling load circuit. A third water pump is provided between the heat pump host module and the indoor terminal module. The third water circuit is sequentially fluidly connected to the terminal outlet of the heat pump host module, the third water pump, the indoor terminal module, and the terminal inlet of the heat pump host module, forming a second closed-loop circulation medium link.

[0019] By adopting the above technical solution, a second closed-loop circulation medium link is constructed, which stably delivers standard chilled water or hot water processed by the heat pump host module to the indoor terminal module, ensuring the rapid response of indoor heating and cooling loads and the accuracy of temperature control. At the same time, the indoor pipeline and the outdoor machine room pipeline are isolated under operating conditions, ensuring the quietness and comfort of the indoor environment.

[0020] Optionally, the air conditioning heat pump system further includes an intelligent anti-interruption and anti-blockage bypass link, which is installed in the first water circuit and includes:

[0021] A landscape bypass pipeline is connected in parallel between the inlet and outlet of the primary side of the intermediate heat exchanger.

[0022] The first valve group is located at the connection between the first water circuit and the landscape bypass pipeline.

[0023] A differential pressure sensor is configured to detect the pressure difference between the inlet and outlet water on the primary side of the intermediate heat exchanger.

[0024] By adopting the above technical solution, when impurities or leaves in the landscape water cause blockage on the primary side of the intermediate heat exchanger and the differential pressure sensor detects an abnormal differential pressure, the landscape bypass pipeline can be automatically opened. This design can prevent the first water pump from being damaged by pressure buildup or the pipeline from bursting, and can also ensure that the ornamental water flow of the outdoor landscape water system is continuous, thereby improving the fault tolerance and operational reliability of the system under harsh working conditions.

[0025] Optionally, the air conditioning heat pump system further includes a natural cooling bypass link, which is connected between the second water circuit and the third water circuit. The natural cooling bypass link includes a natural cooling water supply pipe and a natural cooling water return pipe. The natural cooling water supply pipe is connected in parallel between the secondary side outlet of the intermediate heat exchanger and the indoor terminal module. The natural cooling water return pipe is located between the indoor terminal module and the secondary side inlet of the intermediate heat exchanger. Both the natural cooling water supply pipe and the natural cooling water return pipe are equipped with a second valve group.

[0026] By adopting the above technical solution, during the transitional season or winter, when the indoor core area (such as the data center or the inner commercial area) still has a cooling demand and the outdoor landscape water temperature is extremely low, the system can shut down the heat pump host module and open the natural cooling supply / return water pipeline, allowing the cold landscape water to directly replace the heat of the third water circuit through the intermediate heat exchanger. This completely solves the problem of traditional air conditioners easily shutting down when forced to cool in winter, achieving extremely significant energy-saving effects.

[0027] Optionally, the landscaping release end is provided with a built-in spray pipe, which is connected to the first water pump. The landscaping release end is provided with a water outlet box, and a water flow regulating cover is connected to one side of the water outlet box. The built-in spray pipe is connected to one end of the water flow regulating cover, and water baffles are provided at both ends of the water flow regulating cover. The water baffles are slidably disposed in the water outlet box.

[0028] By adopting the above technical solutions, the outflow pattern of the landscape water system can be dynamically changed according to the real-time heat dissipation / heat absorption needs of the heat pump system. The combination of the water flow regulating cover and the baffle plate makes the outlet width adjustable. When the heat exchange load is high, the outlet width is increased to form a wider waterfall curtain, increasing the contact area between water and air and improving heat exchange performance; when the load is low, it is reduced, presenting a variety of landscape visual effects while saving energy and improving the applicability of the heat pump system.

[0029] Optionally, the water volume regulating cover includes a fixed part, a first expansion part, and a second expansion part. The fixed part is fixedly disposed on one side of the water volume regulating cover, and the first expansion part and the second expansion part are slidably disposed on both sides of the fixed part. The water volume regulating cover is provided with an adjusting component for driving the first expansion part and the second expansion part to move.

[0030] The adjustment assembly includes a bidirectional screw, which is disposed on one side of the water outlet box. The bottom surfaces of the first expansion and the second expansion are each provided with a connecting block, and the bidirectional screw is threadedly connected to the connecting block.

[0031] By adopting the above technical solution, when it is necessary to adjust the width of the waterfall water curtain, first rotate the bidirectional screw. The bidirectional screw drives the first expansion section and the second expansion section to expand to both sides or retract to the middle through the connecting block, thereby realizing the symmetrical and synchronous adjustment of the width of the landscape water curtain and improving the stability of the waterfall water curtain width adjustment.

[0032] Optionally, the bottom surface of the water outlet box is provided with a flow stabilizing groove, the flow stabilizing groove includes a bottom plate and a folding part, the bottom surface of the baffle plate is provided with an elastic sealing part, the elastic sealing part is slidably connected to the flow stabilizing groove, and the water outlet box is provided with a transmission component for cooperating to drive the folding part to extend.

[0033] By adopting the above technical solution, when the water volume in the outlet box increases and the water curtain widens, in order to avoid irregular splashing (damaging the landscape effect) caused by excessive water flow velocity, the bottom elastic sealing part and folding part can be extended to expand the volume of the flow stabilizing channel. Increasing the volume can effectively reduce the water flow velocity, play the role of energy dissipation and flow stabilization, ensure the smoothness and elegance of the waterfall landscape, and at the same time help to ensure the maximum contact area between the waterfall water curtain and the air, thus improving the heat exchange performance.

[0034] Optionally, the transmission assembly includes a bevel gear steering group and a transmission belt group. The bevel gear steering group is disposed on one side of the water outlet box. One end of the bidirectional screw is coaxially connected to the input end of the bevel gear steering group. A lifting block is fixedly connected to one side of the base plate. A transmission screw is rotatably disposed on one side of the water outlet box. The transmission screw is threaded through the lifting block. One end of the transmission belt group is coaxially connected to the output end of the bevel gear steering group via a coupling shaft. The other end of the transmission belt group is coaxially connected to the end of the transmission screw.

[0035] By adopting the above technical solution, the "horizontal width adjustment" of the bidirectional screw and the "vertical depth (volume) adjustment" of the transmission screw are cleverly linked through the steering of the bevel gear steering group and the synchronous transmission of the transmission belt group. By simply controlling the rotation of the bidirectional screw, the water curtain width can be expanded while the flow stabilizing channel automatically descends and expands, achieving a perfect adaptive match between the heat exchange area (width) and the flow stabilizing effect (depth). Ultimately, this helps to ensure the maximum contact area between the waterfall water curtain and the air, thereby improving the heat exchange performance.

[0036] In summary, this application includes the following beneficial technical effects:

[0037] This application completely abandons the traditional, energy-intensive, space-consuming, and aesthetically unappealing cooling towers. It cleverly utilizes outdoor waterfalls, fountains, and other dynamic landscape water features as heat sinks or heat sources for the air conditioning heat pump system. In the hot summer, the large-area atomization and evaporation of water droplets during the cascading water process removes heat; in winter, the stable heat capacity of the large water volume extracts heat. This achieves a win-win situation for both aesthetic appeal and air conditioning heat exchange, significantly reducing the overall building's operating energy consumption.

Detailed Implementation

[0044] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0045] See Figure 1 and Figure 2 An air conditioning heat pump system based on a dynamic landscape water system includes:

[0046] The dynamic landscape water system module 1 includes a landscape pool 2, which is constructed outdoors. A landscape release end 3 is fixedly installed within the landscape pool 2. This release end 3 is configured as a rockery fountain, with embedded nozzles 4 forming a waterfall with a drop of 0.8 to 2.0 meters. This drop design breaks the water flow into fine droplets or mist, significantly increasing the contact area between the water and air, and greatly enhancing the evaporative cooling effect.

[0047] The heat pump main unit module 5 is housed in a machine room 6 built outdoors. The heat pump main unit module 5 is fixedly installed in the machine room 6. The heat pump main unit module 5 mainly includes an evaporator, a condenser, a compressor, and a throttling device, and these four components form a heat pump circulation loop. In this embodiment, a variable frequency water-source heat pump unit is used, with a rated operating noise ≤55dB and a comprehensive energy efficiency ratio (COP) of 4.0-5.5.

[0048] Indoor terminal module 7 includes air conditioning heating and cooling terminal 44, which is installed indoors and is used to receive the cooling or heating output from heat pump main unit module 5 to achieve indoor temperature regulation.

[0049] The water heat exchange circuit 8 includes an intermediate heat exchanger 9, which is fixedly installed in the machine room 6. The intermediate heat exchanger 9 is fixedly connected to the dynamic landscape water system module 1 via a first water circuit 10, the intermediate heat exchanger 9 is fixedly connected to the heat pump host module 5 via a second water circuit 11, and the intermediate heat exchanger 9 is fixedly connected to the indoor terminal module 7 via a third water circuit 12.

[0050] The intelligent control module 13 includes sensors and a controller. Multiple sensors are fixedly installed on the landscape water tank 2, the heat pump main unit module 5, the indoor terminal module 7, and the water-heat exchange circuit 8, respectively, to collect the operating parameters of each module. The controller is installed indoors and is electrically connected to the dynamic landscape water system module 1, the heat pump main unit module 5, the indoor terminal module 7, and each sensor, controlling the coordinated operation of each module based on the parameters collected by the sensors.

[0051] The air conditioning heat pump system, based on the high specific heat capacity of water, relies on a physically isolated architecture consisting of the first water circuit 10, the second water circuit 11, and the third water circuit 12. Under the overall coordination of the intelligent control module 13, it achieves dynamic energy conversion between the natural landscape and the cooling and heating loads of the building's interior. Specific operating conditions are as follows:

[0052] During summer (indoor cooling mode), the indoor terminal module 7 absorbs the building's indoor heat load, and the heated air conditioning return water enters the evaporator of the heat pump main unit module 5 through the third water circuit 12. At this time, the compressor of the heat pump main unit module 5 operates, extracting heat from the third water circuit 12 to produce low-temperature chilled water, which is then returned to the indoor cooling system. Simultaneously, the extracted heat is transferred to the second water circuit 11 in the condenser. The medium in the second water circuit 11, carrying high-temperature waste heat, enters the intermediate heat exchanger 9 and exchanges heat with the first water circuit 10 at the wall surface, transferring heat to the first water circuit 10. During this process, because the second water circuit 11 is a closed, pure medium, it effectively prevents the precision heat exchanger inside the heat pump main unit module 5 from being contaminated by outdoor impurities. The landscape water in the first water circuit 10, which has absorbed the system's waste heat, is pumped to the built-in nozzle 4 embedded in the outdoor artificial mountain and flows out from the landscape release end 3, forming a waterfall with a drop of 0.8 to 2.0 meters. During the fall, the water flow is forcibly broken into fine droplets or mist, and its contact area with the outdoor air increases exponentially. At this time, the water flow efficiently dissipates heat to the outdoor atmosphere through sensible heat exchange and a strong evaporative cooling effect (latent heat release). The cooled water falls back into the landscape pool 2, completing the natural cycle of cooling and heat dissipation.

[0053] During winter (indoor heating mode), the water in the landscape pool 2 acts as a large natural energy harvester, absorbing low-grade heat energy from the outdoor air or surrounding soil. This portion of the landscape water containing low-grade heat energy is sent to the intermediate heat exchanger 9, transferring heat to the second water circuit 11. After absorbing low-grade heat energy, the medium in the second water circuit 11 enters the evaporator of the heat pump main module 5. The compressor of the heat pump main module 5 starts, consuming a small amount of electrical energy to "pump" the extracted low-grade heat energy to a higher temperature, and releases the high-temperature heat to the third water circuit 12 at the condenser. The third water circuit 12 delivers the prepared high-temperature hot water to the indoor terminal module 7, dissipating heat to regulate the indoor temperature.

[0054] During transitional seasons or winter when there is a core area cooling demand (free cooling condition), some large buildings still experience significant cooling needs in their core areas (such as data center 6 and densely populated conference rooms) during winter. In this case, the intelligent control module 13 controls the compressor of the heat pump main unit module 5 to stop operating. The water in the outdoor landscape pool 2 naturally forms low-temperature chilled water due to the extremely low winter temperatures and the evaporation from the waterfall. This natural cooling energy is transported to the intermediate heat exchanger 9 via the first water circuit 10, and then through the second water circuit 11 and the third water circuit 12, before being directly delivered to the indoor terminal module 7 for cooling. This condition achieves true "zero compressor power consumption" cooling, consuming only a small amount of water pump operating power, greatly reducing system energy consumption.

[0055] During operation under any of the above conditions, the controller in the intelligent control module 13 acquires real-time temperature, differential pressure, and flow data from various sensors. When the indoor load increases, the controller increases the frequency of the inverter compressor in the heat pump main unit module 5 and simultaneously increases the head and flow rate of the water pump in the dynamic landscape water system module 1 to increase the waterfall's flow rate and enhance heat exchange. When the indoor temperature reaches the set value, the controller automatically reduces the system's operating frequency and even slows down the waterfall's flow rate to maintain only a basic visual effect, thereby achieving a precise dynamic balance between building energy consumption and outdoor landscape effects.

[0056] For details, see Figure 1 The first water circuit 10 is specifically an outdoor landscape heat absorption and exhaust circuit. A first water pump 14 is installed in the landscape pool 2. The first water circuit 10 is sequentially connected to the landscape pool 2, the first water pump 14, the primary side of the intermediate heat exchanger 9, and the landscape release end 3, and finally flows back to the landscape pool 2, thus forming an open circulating medium link.

[0057] During summer cooling, the first water pump 14 enables the landscaping release end 3 to come into large-area contact with the outdoor air through the waterfall flow, achieving efficient evaporative cooling and heat dissipation. During winter heating, the huge sensible and latent heat of the landscape water body is used as a stable heat source, making full use of the natural heat capacity of the water body and the dynamic water vapor exchange during the landscaping process, thus greatly improving the heat exchange efficiency.

[0058] For details, see Figure 1 The second water circuit 11 is specifically a source-side transport circuit of the main unit. The intermediate heat exchanger 9 and the heat pump main unit module 5 are fixedly connected by a second water pump 15. The second water circuit 11 is sequentially fluidly connected to the source water outlet of the heat pump main unit module 5, the second water pump 15, the secondary side of the intermediate heat exchanger 9, and the source water inlet of the heat pump main unit module 5, thereby forming a first closed-loop circulation medium link.

[0059] In practical applications, the landscape pool 2 often contains impurities such as silt and algae. At this time, the intermediate heat exchanger 9 has the function of physically isolating dirty water from clean water, ensuring the cleanliness of the condenser or evaporator pipes inside the heat pump main unit module 5, avoiding scaling and corrosion of core high-value equipment, and extending the service life of the heat pump main unit module 5.

[0060] For details, see Figure 1 The third water circuit 12 is specifically an indoor terminal heating and cooling load circuit. A third water pump 16 is fixedly connected between the heat pump host module 5 and the indoor terminal module 7. The third water circuit 12 is sequentially fluidly connected to the terminal outlet of the heat pump host module 5, the third water pump 16, the indoor terminal module 7, and the terminal inlet of the heat pump host module 5, thereby forming a second closed-loop circulation medium link.

[0061] During the above process, the standard chilled water or hot water processed by the heat pump host module 5 is stably delivered to the air conditioning heating and cooling terminal 44 of the indoor terminal module 7, ensuring the rapid response of indoor heating and cooling loads and the accuracy of temperature control. At the same time, the indoor pipelines and the outdoor machine room 6 pipelines are isolated under operating conditions, ensuring the quietness and comfort of the indoor environment.

[0062] For details, see Figure 1 The air conditioning heat pump system also includes an intelligent anti-interruption and anti-blockage bypass link, which is connected to the first water circuit 10 and includes:

[0063] Landscape bypass pipe 17 is connected in parallel between the inlet and outlet of the primary side of the intermediate heat exchanger 9.

[0064] The first valve group 18 is fixedly connected to the connection point between the first water circuit 10 and the landscape bypass pipeline 17, and the first valve group 18 is electrically connected to the controller.

[0065] Differential pressure sensor 19 is configured to detect the pressure difference between the inlet and outlet water on the primary side of the intermediate heat exchanger 9.

[0066] Since the landscape pool 2 often contains impurities or leaves, when these impurities or leaves cause blockage on the primary side of the intermediate heat exchanger 9 and the differential pressure sensor 19 detects an abnormal differential pressure, the landscape bypass pipe 17 can be automatically opened by the controller. This setting can prevent the first water pump 14 from being damaged by pressure buildup or the pipe from bursting, while ensuring the continuous flow of ornamental water in the outdoor landscape water system, thus improving the system's fault tolerance and operational reliability under harsh conditions.

[0067] See Figure 1 To further improve the energy-saving effect of the air conditioning heat pump system, the system also includes a natural cooling bypass link, which is fixedly connected between the second water circuit 11 and the third water circuit 12. The natural cooling bypass link includes a natural cooling water supply pipe 20 and a natural cooling water return pipe 21. The natural cooling water supply pipe 20 is connected in parallel between the secondary outlet of the intermediate heat exchanger 9 and the indoor terminal module 7. The natural cooling water return pipe 21 is fixedly connected between the indoor terminal module 7 and the secondary inlet of the intermediate heat exchanger 9. Both the natural cooling water supply pipe 20 and the natural cooling water return pipe 21 are fixedly connected to a second valve group 22, which is electrically connected to the controller.

[0068] In practical applications, indoor core areas (such as data centers and internal commercial areas) still have cooling needs during transitional seasons or winter. When the water temperature of the outdoor landscape pool 2 is extremely low, the system can shut down the heat pump main unit module 5 and open the natural cooling water supply pipeline 20 and the natural cooling water return pipeline 21, allowing the cold landscape water to directly replace the heat of the third water circuit 12 through the intermediate heat exchanger 9. This completely solves the problem of traditional air conditioners easily shutting down during winter cooling, achieving extremely significant energy-saving effects.

[0069] See Figure 2 and Figure 3 The width of the waterfall's outlet affects its heat exchange efficiency with the air. Therefore, an internal nozzle 4 is embedded in the waterfall's release end 3. One end of the internal nozzle 4 is fixedly connected to the first water pump 14. The waterfall's release end 3 also has an outlet box 23 embedded within it. A water flow regulating cover 24 is fixedly connected to the rear side of the outlet box 23, and the other end of the internal nozzle 4 is fixedly connected to the water flow regulating cover 24. Water baffles 25 are fixedly connected to both ends of the front side of the water flow regulating cover 24, and the water baffles 25 are slidably and sealingly connected within the outlet box 23.

[0070] When the first water pump 14 is started, the water flows into the water flow regulating cover 24 through the built-in nozzle 4. Under the restriction of the baffle plate 25, the water flows into the water outlet box 23, and then sprays out from the water outlet box 23 to form a waterfall shape. Finally, it is collected in the landscape pool 2, and so on.

[0071] See Figure 3 To facilitate adjustment of the waterfall's width, the water flow regulating cover 24 includes a fixed part 26, a first expansion part 27, and a second expansion part 28. The fixed part 26 is centrally and fixedly connected to the rear side of the water flow regulating cover 24. The first expansion part 27 and the second expansion part 28 are slidably connected to both sides of the fixed part 26. Two baffle plates 25 are fixedly connected to the first expansion part 27 and the second expansion part 28, respectively.

[0072] In addition, the water outlet box 23 is equipped with an adjustment assembly, which includes a bidirectional screw 29. A bracket 30 is fixedly connected to the rear side of the water outlet box 23. The bidirectional screw 29 is rotatably connected to the bracket 30. Connecting blocks 31 are fixedly connected to the bottom surfaces of the first expansion 27 and the second expansion 28, and the two connecting blocks 31 are threaded onto two opposite threads of the bidirectional screw 29. A geared motor 32 is fixedly connected to one side of the bracket 30. The drive shaft of the geared motor 32 is coaxially fixedly connected to one end of the bidirectional screw 29, and the geared motor 32 is electrically connected to the controller.

[0073] When the width of the waterfall surface needs to be adjusted, the controller starts the geared motor 32. The drive shaft of the geared motor 32 drives the bidirectional screw 29 to rotate. At this time, the bidirectional screw 29 drives the first expansion section 27 and the second expansion section 28 to move in opposite directions through the connecting block 31. Under the limiting and adjusting action of the baffle plate 25, the width of the waterfall surface is finally adjusted. This achieves symmetrical and synchronous adjustment of the width of the landscape water curtain.

[0074] It is worth noting that, see Figure 4 and Figure 5 As the width of the waterfall surface increases, incomplete or irregular splashing can easily occur. Therefore, a flow-stabilizing groove 33 is fixedly connected to the bottom surface of the water outlet box 23. The flow-stabilizing groove 33 includes a base plate 34 and a folding part 35. The base plate 34 is fixedly connected to the bottom surface of the water outlet box 23 via the folding part 35. An elastic sealing part 36 is slidably installed on the bottom surface of the baffle plate 25. The elastic sealing part 36 mainly consists of a soft sealing block 37 and a spring 38. The soft sealing block 37 is adapted to the interior of the flow-stabilizing groove 33. Under the action of the spring 38, the soft sealing block 37 rises and falls with the rise and fall of the flow-stabilizing groove 33, thereby achieving a sealing effect.

[0075] In addition, the water outlet box 23 is also equipped with a transmission assembly, which includes a bevel gear steering group 39 and a transmission belt group 40. The bevel gear steering group 39 is fixedly installed on one side of the bracket 30. The bevel gear steering group 39 includes an input end and an output end, and the other end of the bidirectional screw 29 is coaxially and fixedly connected to the input end of the bevel gear steering group 39. A lifting block 41 is fixedly connected to one side of the base plate 34, and a fixing frame 42 is fixedly connected to one side of the water outlet box 23. A transmission screw 43 is rotatably connected inside the fixing frame 42. The transmission screw 43 passes through the lifting block 41 and is threadedly connected to the lifting block 41. The transmission belt group 40 has two connecting ends. One connecting end of the transmission belt group 40 is coaxially and fixedly connected to the output end of the bevel gear steering group 39 through a coupling shaft, and the other connecting end of the transmission belt group 40 is coaxially and fixedly connected to the end of the transmission screw 43.

[0076] It is worth mentioning that the gear ratio of the bevel gear steering assembly 39 is 3, meaning that the input is a small gear and the output is a large gear. This configuration allows the flow stabilizing trough 33 to increase in depth and volume proportionally with the increase in the width of the waterfall surface, achieving a perfect adaptive match between the heat exchange area and the flow stabilization effect.

[0077] When the bidirectional screw 29 rotates, it drives the bevel gear steering assembly 39 to drive the transmission belt assembly 40 through the coupling shaft. The transmission belt assembly 40 drives the transmission screw 43 to rotate, and the transmission screw 43 then drives the bottom plate 34 to rise and fall through the lifting block 41, ultimately changing the depth and volume of the flow stabilizing trough 33.

[0078] Working principle of an air conditioning heat pump system based on a dynamic landscape water system:

[0079] The air conditioning heat pump system, based on the high specific heat capacity of water, relies on a physically isolated architecture consisting of the first water circuit 10, the second water circuit 11, and the third water circuit 12. Under the overall coordination of the intelligent control module 13, it achieves dynamic energy conversion between the natural landscape and the cooling and heating loads of the building's interior. Specific operating conditions are as follows:

[0080] During summer (indoor cooling mode), the indoor terminal module 7 absorbs the heat load from the building's interior. The heated air conditioning return water enters the evaporator of the heat pump main unit module 5 through the third water circuit 12. At this time, the compressor of the heat pump main unit module 5 operates, extracting heat from the third water circuit 12 to produce low-temperature chilled water, which is then returned to the indoor cooling system. Simultaneously, the extracted heat is transferred to the second water circuit 11 in the condenser. The medium in the second water circuit 11, carrying high-temperature waste heat, enters the intermediate heat exchanger 9 and exchanges heat with the first water circuit 10 at the wall surface, transferring heat to the first water circuit 10. During this process, because the second water circuit 11 is a closed, pure medium, it effectively prevents the precision heat exchanger inside the heat pump main unit module 5 from being contaminated by outdoor impurities. The landscape water in the first water circuit 10, which has absorbed the system's waste heat, is pumped to the built-in nozzle 4 embedded in the outdoor artificial hill and flows out from the water outlet box 23, forming a waterfall with a drop of 0.8 to 2.0 meters. During the fall, the water flow is forcibly broken into fine droplets or mist, and its contact area with the outdoor air increases exponentially. At this time, the water flow efficiently dissipates heat to the outdoor atmosphere through sensible heat exchange and a strong evaporative cooling effect (latent heat release). The cooled water falls back into the landscape pool 2, completing the natural cycle of cooling and heat dissipation.

[0081] During winter (indoor heating mode), the water in the landscape pool 2 acts as a large natural energy harvester, absorbing low-grade heat energy from the outdoor air or surrounding soil. This portion of the landscape water containing low-grade heat energy is sent to the intermediate heat exchanger 9, transferring heat to the second water circuit 11. After absorbing low-grade heat energy, the medium in the second water circuit 11 enters the evaporator of the heat pump main module 5. The compressor of the heat pump main module 5 starts, consuming a small amount of electrical energy to "pump" the extracted low-grade heat energy to a higher temperature, and releases the high-temperature heat to the third water circuit 12 at the condenser. The third water circuit 12 delivers the prepared high-temperature hot water to the indoor terminal module 7, dissipating heat to regulate the indoor temperature.

[0082] During transitional seasons or winter when there is a core area cooling demand (free cooling condition), some large buildings still experience significant cooling needs in their core areas (such as data center 6 and densely populated conference rooms) during winter. In this case, the intelligent control module 13 controls the compressor of the heat pump main unit module 5 to stop operating. The water in the outdoor landscape pool 2 naturally forms low-temperature chilled water due to the extremely low winter temperatures and the evaporation from the waterfall. This natural cooling energy is transported to the intermediate heat exchanger 9 via the first water circuit 10, and then through the second water circuit 11 and the third water circuit 12, before being directly delivered to the indoor terminal module 7 for cooling. This condition achieves true "zero compressor power consumption" cooling, consuming only a small amount of water pump operating power, greatly reducing system energy consumption.

[0083] During operation under any of the above conditions, the controller in the intelligent control module 13 acquires real-time temperature, differential pressure, and flow data from various sensors. When the indoor load increases, the controller increases the frequency of the inverter compressor in the heat pump main unit module 5 and simultaneously increases the head and flow rate of the water pump in the dynamic landscape water system module 1 to increase the waterfall's flow rate and enhance heat exchange. When the indoor temperature reaches the set value, the controller automatically reduces the system's operating frequency and even slows down the waterfall's flow rate to maintain only a basic visual effect, thereby achieving a precise dynamic balance between building energy consumption and outdoor landscape effects.

[0084] In summary, this application completely eliminates the need for traditional, energy-intensive, space-consuming, and aesthetically unappealing cooling towers. It cleverly utilizes outdoor waterfalls, fountains, and other dynamic landscape water features as heat sinks or heat sources for the air conditioning heat pump system. In the hot summer, the large-area atomization and evaporation of water droplets during the cascading water process removes heat; in winter, the stable heat capacity of the large water volume extracts heat. This achieves a win-win situation for both aesthetic appeal and air conditioning heat exchange, significantly reducing the overall building's operating energy consumption.

[0085] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
