The widespread use of air conditioners leads to high electricity consumption, which is not conducive to sustainable development. Existing energy-saving air conditioners on the market are generally more expensive than ordinary air conditioners, which makes them difficult to promote and apply.

[0016] The utility model provides an air conditioner self-condensing water cooling structure, which solves the problem of high energy consumption or high cost of existing air conditioners, reduces energy consumption, improves energy utilization efficiency, and realizes sustainable utilization of resources at a low cost.
[0017] See also Figure 1 The present invention provides an air conditioner self-condensation water cooling structure according to one embodiment, which can be applied to the common air conditioner types currently. The air conditioner includes an air conditioner indoor unit 1 and an air conditioner outdoor unit 2. The relevant specific structure is not described here in detail. The air conditioner indoor unit 1 is connected to a condensation water drain pipe 3, a filter 4 is connected to the condensation water drain pipe 3, and a horizontally arranged water sponge 5 is sealed at the end of the condensation water drain pipe 3. The water sponge 6 is filled in the water sponge 5. The end of the water sponge 5 is closed, and a plurality of drainage holes 7 are provided on the lower side of the water sponge 5. An air conditioner outdoor unit evaporator 8 is provided in the casing of the air conditioner outdoor unit 2, and the water sponge 5 is located directly above the air conditioner outdoor unit evaporator 8. When the present solution is working, as the air conditioner is used, the condensation water first enters the filter 4 through the condensation water drain pipe 3 for filtration, and then enters the water sponge 5. The water sponge 6 allows the condensation water to flow out evenly from the drainage holes 7 and drip onto the air conditioner outdoor unit evaporator 8, which has a cooling effect, thereby reducing the consumption of electric energy in disguise.
[0018] More specifically, the filter 4 comprises a vertically arranged filter tube, similar to a plastic bottle, with openings at the top and bottom ends serving as the water inlet and outlet, respectively. These openings are sealed to the pipeline to form a continuous condensate drain pipe 3. The filter tube is filled with a filter sponge 9 or other porous material to provide a filter. Since only larger solid impurities need to be filtered out, a relatively low-cost sponge is preferred.
[0019] The watering pipe 5 is a hard pipe similar to a threading pipe. In this solution, a sponge is set inside and small holes are directly opened in the pipe body to achieve a uniform watering effect at a very low cost. Figure 1 、 Figure 2 This is a schematic diagram only. In practice, the sprinkler pipe 5 can be a thinner tube that matches the condensate drain pipe 3 to facilitate connection and reduce the amount of water that can be retained, facilitating the dripping of condensate. The drain holes 7 can be smaller diameter holes drilled using an electric drill. The length of the sprinkler pipe 5 matches the length of the air conditioner's outdoor evaporator 8, and the drain holes 7 are evenly distributed along the length of the sprinkler pipe 5 so that the dripping condensate covers the entire length of the air conditioner's outdoor evaporator 8 as much as possible. In some common air conditioning systems, the outdoor evaporator 8 has a heat dissipating fin structure and is located along the back and one side of the air conditioner's housing. The fan, compressor, etc. are located in the rest of the housing. Alternatively, the sprinkler pipe 5 can be located above the outdoor evaporator 8. For example, if the outdoor evaporator 8 is curved, the sprinkler pipe 5 can be shaped similarly. The condensate drips onto the heat dissipating fin structure.
[0020] Preferably, a liquid level control boosting system can be added to more effectively enhance the air conditioning condensate self-cooling system. Specifically, in the condensate drain pipe 3, a water tank 10 and a boosting pump 11 are connected downstream of the filter 4. A liquid level sensor 12 is provided on the water tank 10 and connected to the boosting pump 11. Filtered condensate first enters the water tank 10. When the amount of condensate is high, the liquid level sensor 12 detects that the liquid level in the water tank 10 is above a set value, automatically controlling the boosting pump 11 to start, pressurizing the water in the water tank 10 and discharging it through the drain hole 7.
[0021] A refrigerant pipe 13 is also connected between the air conditioner indoor unit 1 and the air conditioner outdoor unit 2. The refrigerant pipe 13 is usually a hard copper pipe. The condensate drain pipe 3 can be a soft water pipe for flexible connection. The condensate drain pipe 3 and the refrigerant pipe 13 are arranged side by side, for example, fixed by a band, so that the structure is more stable and neat. The top of the box body of the air conditioner outdoor unit 2 usually has a cover ( Figure 1 、 Figure 2(The figure shows the schematic diagram after removing the cover plate.) In this solution, the cover plate is installed after the water pipe 5 is installed and fixed to protect the internal structure. Based on this solution, a new energy-saving air conditioning structure can be formed, and it can also be used as an additional accessory product for retrofitting existing air conditioning equipment.
[0022] In summary, energy conservation and emission reduction have become urgent tasks. This new air conditioner self-condensation cooling structure utilizes the air conditioner's own condensation water to cool the outdoor unit evaporator, thereby achieving energy conservation and consumption reduction, helping to improve energy efficiency and achieve sustainable resource utilization. Air conditioners using this solution are estimated to reduce energy consumption by approximately 10%-20%. Furthermore, this solution is simple in structure and low in cost, making it suitable for widespread application.
