[0002] In summer, air conditioners are essential equipment for cooling rooms. The outdoor unit of an air conditioner is the main part of the air conditioner system for heat dissipation, and its heat dissipation capacity directly affects the refrigeration efficiency of the air conditioner. Due to the high outdoor environmental temperature in summer, in order to provide more cold air volume, it is necessary to increase the fan power to better cool the gaseous refrigerant, which leads to an increase in the operating energy consumption of the air conditioner. Moreover, the high temperature also often causes the compressor and fin heat exchanger of the outdoor unit of the air conditioner to operate at a higher temperature, affecting the performance of the air conditioner; on the other hand, during the refrigeration process of the air conditioner, the indoor unit of the air conditioner generates a large amount of condensate water. The temperature of the condensate water generated by the indoor unit of the air conditioner is generally between 11 and 13 °C, which is much lower than the outdoor temperature. However, the condensate water of the indoor unit of the air conditioner is usually directly discharged without recycling, resulting in a waste of energy.

Specific embodiments
[0018] The utility model provides an air-conditioning condensate recovery and utilization device. To make the purpose, technical solution and effects of the utility model clearer and more definite, the following examples are given with reference to the attached drawings for further detailed description of the utility model. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

Therefore, it cannot be understood as a limitation to the present utility model. In addition, "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.
[0020] Please refer to Figure 1 , the present utility model provides an air-conditioning condensate recovery and utilization device, which includes an air-conditioning indoor unit drain pipe 3 and a spray pipe 4. The air-conditioning indoor unit drain pipe 3 is used to discharge the condensate generated during the operation of the air-conditioning indoor unit 1 into the spray pipe 4. The spray pipe 4 is arranged in the air-conditioning outdoor unit 2 and is used to spray condensate on the fin heat exchanger 9 of the air-conditioning outdoor unit 2 to cool it down. The air-conditioning indoor unit drain pipe 3 can be directly connected to the spray pipe 4 to directly discharge the condensate generated by the air-conditioning indoor unit 1 into the spray pipe 4, and then directly spray it onto the fin heat exchanger 9 of the air-conditioning outdoor unit 2. However, since the speed of condensate generation by the air-conditioning indoor unit 1 is relatively slow, if it is directly discharged into the spray pipe 4 for spraying, the water pressure in the spray pipe 4 will be insufficient, affecting the spraying effect and thus the heat dissipation effect. Therefore, preferably, an intermediate water collection container can be arranged between the air-conditioning indoor unit drain pipe 3 and the spray pipe 4. First, the condensate generated by the air-conditioning indoor unit 1 is collected and stored to a certain amount, and then transported to the spray pipe 4 for spraying to ensure that the water pressure in the spray pipe 4 can meet the requirements of spraying and cooling. The condensate sprayed by the spray pipe 4 onto the fin heat exchanger 9, part of which absorbs the heat of the fin heat exchanger 9 and turns into gas and evaporates into the ambient air, and the remaining part will flow down along the fin heat exchanger 9 and be collected for reuse.
[0021] Furthermore, for the air conditioner condensate water recycling device described above, it further includes an air conditioner outdoor unit chassis 5. The output end of the air conditioner indoor unit drain pipe 3 is connected to the air conditioner outdoor unit chassis 5. The air conditioner outdoor unit chassis 5 serves as an intermediate water collection container and is used to store the condensate water generated during the operation of the air conditioner indoor unit 1. In this embodiment, the air conditioner outdoor unit chassis 5 is obtained by structurally modifying the housing of the air conditioner outdoor unit 2. As long as it can store a certain amount of water, does not leak, and does not affect the use of other working components of the air conditioner outdoor unit 2 and other basic requirements of the housing, the specific structure of the air conditioner outdoor unit chassis 5 is not specifically limited. The air conditioner outdoor unit chassis 5 not only collects and stores the condensate water discharged from the air conditioner indoor unit drain pipe 3, but also collects the water flowing down after the spray pipe 4 sprays onto the fin heat exchanger 9, realizing the recycling of condensate water and saving energy.
[0022] Furthermore, for the air conditioner condensate water recycling device described above, a submersible pump 6 is provided inside the air conditioner outdoor unit chassis 5. The output end of the submersible pump 6 is connected to a water delivery pipe 7, and the water delivery pipe 7 is connected to the spray pipe 4. The submersible pump 6 is used to pump the condensate water stored in the air conditioner outdoor unit chassis 5 into the spray pipe 4. Due to the height difference between the air conditioner outdoor unit chassis 5 and the spray pipe 4, the condensate water located in the air conditioner outdoor unit chassis 5 needs to rely on the kinetic energy provided by the submersible pump 6 to reach the spray pipe 4, and thus the condensate water obtains potential energy to spray onto the fin heat exchanger 9 below the spray pipe 4. In this embodiment, the output end of the water delivery pipe 7 is connected to a non-end position of the spray pipe 4.
[0023] For the air conditioner condensate water recycling device described above, a water level switch 8 is further provided in the air conditioner outdoor unit chassis 5. The water level switch 8 is connected to the submersible pump 6 in a controlled manner and is used to detect the water level of the condensate water in the chassis to control the start and stop of the submersible pump 6. In this embodiment, the water level switch 8 preferably selects an electronic liquid level switch and can be installed horizontally or vertically according to the water storage capacity of the air conditioner outdoor unit chassis 5. When the condensate water collected in the air conditioner outdoor unit chassis 5 reaches a certain water level, it will trigger the water level switch 8 to close the circuit, thereby controlling the submersible pump 6 to start working and pumping the condensate water in the air conditioner outdoor unit chassis 5 towards the spray pipe 4; when the condensate water collected in the air conditioner outdoor unit chassis 5 decreases and drops to a certain water level, it triggers the water level switch 8 to open the circuit, and the submersible pump 6 stops working and no longer pumps water to the spray pipe 4.
[0024] As an optimization, in the air-conditioning condensate water recycling device, the spray pipe 4 is located at the top of the fin heat exchanger 9 of the outdoor unit 2 of the air conditioner, and the spray pipe 4 is arranged horizontally as a whole in accordance with the installation posture of the fin heat exchanger 9. Since the fin heat exchanger 9 of the outdoor unit 2 of the air conditioner is installed inside the outdoor unit 2 of the air conditioner like a wall, the spray pipe 4 is arranged at the top of the fin heat exchanger 9 and laid along the length of the fin heat exchanger 9. The sprayed condensate water flows downwards on the surface of the fin heat exchanger 9, so that the spraying area of the condensate water can cover the entire fin heat exchanger 9 as much as possible, and the spraying is more accurate, realizing the optimization of the heat dissipation effect.
[0025] In the air-conditioning condensate water recycling device, a plurality of spray holes 10 are provided on the spray pipe 4. The plurality of spray holes 10 penetrate through the side wall of the spray pipe 4 and are arranged in an array along the length direction of the spray pipe 4. In this embodiment, the plurality of spray holes 10 face downwards directly at the fin heat exchanger 9. The distance between every two adjacent spray holes 10 is preferably a small distance, so as to arrange as many spray holes 10 as possible, thereby increasing the spraying coverage area of the condensate water; the aperture of each spray hole 10 is much smaller than the inner diameter of the spray pipe 4 and the inner diameter of the water delivery pipe 7, ensuring that the water pressure in the spray pipe 4 can meet the requirement for each spray hole 10 to spray out condensate water.
[0026] In summary, by arranging the spray pipe 4 on the outdoor unit 2 of the air conditioner, the present utility model transports the condensate water generated by the indoor unit 1 of the air conditioner into the spray pipe 4, achieving the purpose of recycling the condensate water for heat dissipation of the outdoor unit 2 of the air conditioner:
[0027] Advantage 1: Recycling water resources, reducing the energy consumption of air-conditioning operation, and saving energy and protecting the environment;
[0028] Advantage 2: Improving the heat exchange efficiency of the fin heat exchanger 9 and extending its service life.
[0029] It can be understood that for those of ordinary skill in the art, equivalent replacements or changes can be made according to the technical solution of the present utility model and its inventive concept, and all such changes or replacements should fall within the protection scope of the appended claims of the present utility model.
