Description

Technical Field

[0001] This application relates to the field of heating, ventilation and air conditioning equipment technology, specifically to the field of a high-efficiency air conditioning condenser system. Background Technology

[0002] In high-load operating environments such as industrial plants, data centers, and communication base stations, the outdoor condenser of an air conditioning system is constantly exposed to high temperatures, and its heat dissipation performance directly affects the overall energy efficiency and lifespan of the equipment. In particular, during the high temperatures of summer or in enclosed spaces, the ambient temperature often approaches or even exceeds the condensing temperature, leading to a reduction in the heat exchange temperature difference and a significant decrease in heat dissipation efficiency.

[0003] In such operating conditions, common improvement measures include optimizing the condenser installation layout or using spray cooling. However, these methods are easily constrained by the installation environment, resulting in limited installation space and inconvenient maintenance. Especially in industrial scenarios where multiple outdoor units are centrally located, there is a lack of a compact, efficient cooling solution that requires no external water source, has low maintenance costs, and can operate sustainably.

[0004] Therefore, there is an urgent need for a new type of air conditioning condenser system that can achieve stable and efficient spray cooling without relying on external water supply under limited installation space conditions, while taking into account energy saving and engineering feasibility. Summary of the Invention

[0005] This application proposes a high-efficiency condenser system for air conditioning to improve the energy efficiency and operational reliability of refrigeration systems.

[0006] To achieve the above objectives, the present application adopts the following technical solution: This application proposes an air conditioning high-efficiency condenser system, including an outdoor condenser installed on a bracket and a water tank for recovering condensate from the indoor evaporator; It also includes a booster pump connected to the water tank at the water inlet, a spray head installed on the upper end of the outdoor condenser, a spray water supply circuit connecting the booster pump and the spray head, and a solenoid valve installed on the spray water supply circuit for controlling the opening and closing of the spray head. It also includes a water collection tank located below the outdoor condenser for collecting the return water after spraying, and the water collection tank is connected to the water tank through a water collection channel.

[0007] In this way, by recycling the condensate from the indoor unit as the spray water source, water resources can be self-circulated without relying on external water supply; by utilizing the height difference created by the bracket installation, the return water in the collection tank can flow back to the water tank naturally through the collection water path, achieving gravity return, eliminating the need for a return water pump, reducing energy consumption and failure rate; combined with a solenoid valve, on-demand spraying can be achieved, improving the system's energy efficiency and operational reliability.

[0008] In some possible implementations, the water tank includes a condensate chamber and a recovery water chamber that are separated from each other. The condensate chamber is used to store condensate from the indoor evaporator, and the recovery water chamber is used to receive and temporarily store spray return water from the collection tank.

[0009] In some possible implementations, a filter is provided on the water inlet path of the condensate chamber.

[0010] In some possible implementations, a check valve is provided downstream of the filter.

[0011] In some possible implementations, a water level sensor is provided inside the condensate chamber.

[0012] In some possible implementations, a partition is provided between the condensate chamber and the recovery water chamber, and a sedimentation zone for settling impurities is formed at the bottom of the recovery water chamber.

[0013] In some possible implementations, the upper part of the partition is provided with a filter screen for filtering the supernatant in the recovery water chamber and allowing it to flow into the condensate water chamber.

[0014] In some possible implementations, the upper part of the water recovery chamber is provided with an overflow port for draining excess water from the system.

[0015] In some possible implementations, the bottom of the water collection tank has an inclined structure. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0019] Please refer to Figure 1As shown in the figure, an embodiment of this application provides an air conditioning high-efficiency condenser system, including an outdoor condenser 2 installed on a bracket 21, and a water tank for recovering condensate produced by the indoor evaporator 1. The water tank performs multiple functions including condensate collection, return water sedimentation, and purification circulation.

[0020] During system operation, the low-temperature condensate generated by the indoor evaporator 1 during cooling is transported through a conduit and condensate collection circuit 100 to the condensate chamber 3 of the water tank. To ensure the cleanliness of the water entering the system, the condensate undergoes preliminary filtration through filter 11 before entering the condensate chamber 3 to remove large particulate impurities such as dust and fibers carried in the air. A check valve 12 is installed downstream of filter 11 to prevent backflow of water in the pipeline.

[0021] It also includes a booster pump 31, whose inlet is connected to the condensate chamber 3. The outlet of the booster pump 31 is connected to the spray water supply circuit 200, which extends to the top of the outdoor condenser 2 and is connected to the spray head 33 located on the upper part of the outdoor condenser 2. The spray water supply circuit 200 is equipped with a solenoid valve 32, which can be independently opened and closed according to the operating status of the outdoor condenser 2 or the ambient temperature signal, thereby achieving the purpose of on-demand spraying and energy-saving operation. That is, each outdoor condenser 2 is independently equipped with a solenoid valve 32.

[0022] The spray head 33 evenly sprays low-temperature water mist onto the fin surface of the outdoor condenser 2, significantly reducing its surface temperature by utilizing the heat absorption effect of water evaporation, improving heat exchange efficiency, thereby reducing condensing pressure and compressor load, and improving the overall energy efficiency ratio.

[0023] The return water after spraying is collected by a water collection tank 41 located below the outdoor condenser 2. The bottom of the water collection tank 41 is inclined, with a drain outlet at the lowest point to ensure that the accumulated water can be drained quickly, preventing the growth of microorganisms or the generation of odors. The water collection tank 41 is connected to the water tank's recovery water chamber 4 via a water collection passage 300. Because the installation height of the bracket 21 makes the water collection tank 41 higher than the water tank, the return water can flow naturally into the recovery water chamber 4 by gravity, achieving pump-free gravity-flow return water, effectively reducing system energy consumption and failure risk.

[0024] The recovery water chamber 4 and the condensate water chamber 3 are physically separated by a partition 45. A sedimentation zone 42 is formed at the bottom of the recovery water chamber 4, where the spray return water settles, allowing impurities such as silt and dust to settle naturally. Preferably, the sedimentation zone 42 can be provided with a slope or V-shaped structure, which facilitates the accumulation of suspended solids towards the center or low point, making subsequent centralized cleaning and maintenance easier. A filter screen 44 is provided on the upper part of the partition 45. The supernatant in the recovery water chamber 4 flows slowly into the condensate water chamber 3 through this filter screen 44, completing the passive purification and recycling of water quality. The filter screen 44 can be made of common filter materials such as PP cotton, and its two sides can be clamped and fixed using perforated stainless steel mesh, etc., without specific limitations.

[0025] To ensure stable system operation, a water level sensor 34 is installed in the condensate chamber 3 to monitor water level changes in real time. When the water level is lower than the set threshold, the control system can automatically shut off the booster pump 31 or some solenoid valves 32 to stop or reduce the spray circulation and prevent equipment damage caused by dry pump operation.

[0026] In addition, the upper part of the water recovery chamber 4 is equipped with an overflow port 43. When the water intake of the system increases abnormally or the drainage is not smooth, the excess water can be discharged through the overflow port 43 to prevent the water tank from overflowing and ensure the safety of the system.

[0027] In this embodiment, the indoor unit condensate is recycled as the spray water source, realizing the self-circulation of water resources without relying on external water supply; the return water in the water collection tank 41 is naturally returned to the water tank through the collection water circuit 300 by utilizing the height difference formed by the bracket installation, realizing gravity return, eliminating the need to configure a return water pump, reducing energy consumption and failure rate; combined with the solenoid valve 32, on-demand spraying can be realized, improving the system's energy efficiency and operational reliability.

[0028] As stated above, this case protects a high-efficiency air conditioning condenser system, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
