As a widely used device in modern buildings and industries, air conditioning units play a key role in regulating indoor temperature and humidity.

[0003] The novel waste heat recovery device for air conditioning units, disclosed in Publication No. CN219841642U, includes a heat exchange cylinder with a top cover fixed to its upper surface. A first air collection chamber is provided at the lower end of the top cover, and a second air collection chamber is provided on the inner surface of the lower end of the heat exchange cylinder. This device adopts a vertical structure with multiple sets of heat-conducting pipes distributed. The scraping plates are interlocked and movable to scrape away scale, which can be completely removed. The threaded rod and scraping plates are built-in, eliminating the need for openings and preventing heat loss. However, current air conditioning units generate heat during use, which is usually directly discharged into the surrounding environment. This not only causes a great waste of energy and low waste heat utilization rate, but also causes thermal pollution to the surrounding environment. Furthermore, the dry air can cause dry skin, throat discomfort, and may also lead to static electricity and other problems that affect operation.

[0004] Therefore, it is necessary to design an air conditioning unit that can recover and reuse the heat generated by the operation of the air conditioning unit during heating, while condensing it into water and spraying it out to humidify the incoming air, thereby reducing energy consumption, improving waste heat utilization, improving air quality, and reducing environmental pollution. Summary of the Invention

[0005] To overcome the shortcomings of current air conditioning units that generate heat during operation, which is usually directly discharged into the surrounding environment, resulting in significant energy waste, low waste heat utilization, thermal pollution, and dry air causing skin dryness, throat discomfort, and static electricity that can affect operation, this invention provides an air conditioning unit that can recover and utilize the heat generated by the air conditioning unit during heating, while simultaneously condensing it into water that is sprayed out to humidify the incoming air, thereby reducing energy consumption, improving waste heat utilization, improving air quality, and reducing environmental pollution.

The air conditioning unit body is provided with a recovery component for recovering and utilizing the heat generated during the operation of the air conditioning unit body. The lower right side of the air conditioning unit body is provided with a humidification component for spraying out condensed water to humidify the air.

[0007] Furthermore, a return air vent is located on the upper right side of the air conditioning unit.

The upper right part of the air conditioning unit is connected to the cover, the connecting pipe is connected to the cover, the suction fan is connected to the lower left inner side of the connecting pipe, the insulation pipe is connected to the lower right part of the connecting pipe, the insulation pipe is connected to the air conditioning unit and the air inlet pipe, and multiple partitions are connected to the air inlet pipe, the two upper partitions are both connected to the insulation pipe.

[0009] Furthermore, the cover is wider at the bottom and narrower at the top.

[0010] Furthermore, the humidification component includes a base, a liquid storage tank, a water pump, a spray frame, and spray nozzles. The base is connected to the lower right side of the air conditioning unit body. The base is connected to the insulation pipe. The liquid storage tank is connected to the base. The lower partition is connected to the liquid storage tank. The water pump is connected to the right side of the liquid storage tank. The spray frame is connected to the water pump. The spray frame is connected to the air inlet pipe. Multiple spray nozzles are connected to the spray frame, and all spray nozzles pass through the air inlet pipe.

[0011] Furthermore, the nozzles are evenly distributed along the air inlet duct.

[0012] The beneficial effects of this utility model are as follows: This utility model heats the room by allowing air to enter the air conditioning unit, while simultaneously drawing out heat through a fan. The hot air then enters the insulation pipe, where it condenses into water due to the temperature difference and falls into the liquid storage tank for collection. The water is then sprayed out from the nozzle to humidify the air. This allows the heat generated by the air conditioning unit during heating to be recovered and reused, while the condensed water sprayed out humidifies the incoming air, reducing energy consumption, improving waste heat utilization, improving air quality, and reducing environmental pollution.
