[0002] Currently, air conditioners on the market are generally divided into air-cooled and water-cooled types. Air-cooled air conditioners have fewer cooling components, a simpler system, and lower manufacturing costs, but they have lower energy efficiency ratios, poorer cooling performance, and higher power consumption. Water-cooled air conditioners, on the other hand, have more cooling components, a more complex system, and higher manufacturing costs, but they have higher energy efficiency ratios, better cooling performance, and lower power consumption. However, their water systems require a large footprint, have high maintenance costs, and a high failure rate. If a malfunction occurs, the air conditioner cannot function properly, affecting daily life and industrial production, indicating lower reliability. Therefore, there is an urgent need for an air conditioner that can improve cooling efficiency, ensure reliability, and have lower manufacturing costs. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1The present invention provides an energy-saving air conditioner, which includes a cooling device and a refrigeration device 40. The cooling device and the refrigeration device 40 are connected. Both the cooling device and the refrigeration device 40 are key components for achieving temperature regulation. The cooling device is usually used to blow out hot air, and the refrigeration device 40 is usually used to blow out cold air.

[0028] It should be noted that in the air conditioning system, the refrigerant circulates between the cooling device and the refrigeration device 40. When the refrigerant passes through the cooling device, it releases heat, which cools the high-temperature and high-pressure refrigerant gas and turns it into a liquid state, thus achieving heating. When the refrigerant passes through the refrigeration device 40, it absorbs heat, and the low-pressure and low-temperature refrigerant liquid evaporates into a gas, thereby lowering the indoor temperature and achieving cooling.

[0029] Please see Figure 2 The cooling device includes a fan 10, a condenser 20, and an energy-saving module 30. The condenser 20 has a cooling coil 201 for supplying refrigerant flow, and the air intake of the fan 10 faces the cooling coil 201. The energy-saving module 30 includes a water tank 301 and a water outlet pipe 302. The water outlet pipe 302 is connected to the water tank 301 and connected to the condenser 20. The water outlet pipe 302 is used to cool the cooling coil 201.

[0030] In practical applications, a cooling coil 201 is formed inside the condenser 20. The refrigerant flows within the cooling coil 201. Typically, the refrigerant enters the cooling coil 201 in a high-temperature, high-pressure gaseous state, and needs to condense into a liquid state when it flows out of the cooling coil 201. During this process, the condenser 20 needs to dissipate heat rapidly, thereby enabling the refrigerant in the cooling coil 201 to condense into a liquid quickly, improving cooling efficiency.

[0031] Therefore, this application includes a fan 10 and an energy-saving module 30. The fan 10 is typically installed on one side of the condenser 20, with its air intake facing the cooling coil 201. Accelerated airflow is used to improve the heat dissipation efficiency of the condenser 20. The airflow across the surface of the condenser 20 carries away the heat released by the refrigerant, further accelerating heat dissipation. Simultaneously, the energy-saving module 30 includes a water tank 301 and a water outlet pipe 302. The water outlet pipe 302 is connected to the condenser 20. The liquid medium (water) in the water tank 301 flows to the condenser 20 through the water outlet pipe 302. The liquid medium (water) flowing through the condenser 20 absorbs the heat released by the refrigerant, further improving the heat dissipation efficiency of the condenser 20.

[0032] It is understood that the water outlet pipe 302 can achieve cooling by spraying water onto the surface of the condenser 20, or by exchanging heat with the cooling coil 201. This application does not limit the cooling method of the water outlet pipe 302.

[0033] Compared to existing technologies, this application combines air cooling and water cooling. In the water cooling system, the liquid medium (water) can directly exchange heat with the cooling coil 201. Compared to air cooling, the heat transfer coefficient is higher during liquid-solid heat exchange, resulting in better heat exchange and significantly improving the device's heat dissipation efficiency. When the ambient temperature is high, both cooling methods operate simultaneously to reduce the condensation temperature, lower power consumption, and achieve energy savings. Furthermore, this device has a low manufacturing cost and good economic efficiency. When the ambient temperature is not high, only the fan 10 needs to be operated, saving costs. Moreover, if the water cooling system fails, the device can still continue to operate using the air cooling system, greatly improving its practicality and preventing production and daily life disruptions due to water cooling failures, thus enhancing the device's reliability.

[0034] Please see Figure 2 and Figure 3 The water outlet pipe 302 includes a first pipe 3021 and a second pipe 3022. The first pipe 3021 is connected to the water tank 301 and the second pipe 3022 respectively. The second pipe 3022 is connected to the top of the condenser 20. The second pipe 3022 has multiple water outlets 30221 on the side facing the condenser 20. The water outlets 30221 are used to spray water onto the outer surface of the condenser 20.

[0035] In practical applications, the first pipe 3021 is used to guide the liquid medium (water) in the water tank 301 to the second pipe 3022. The second pipe 3022 has an outlet 30221. The liquid medium (water) is sprayed out from the outlet 30221 and sprayed onto the outer surface of the condenser 20. Since the second pipe 3022 is located at the top of the condenser 20, the liquid medium (water) flows from the top to the bottom of the condenser 20. During this process, the liquid medium (water) can more easily carry away the heat released by the refrigerant in the cooling coil 201, thereby accelerating the condensation speed of the refrigerant and improving the cooling efficiency.

[0036] Please refer to it again. Figure 2 The energy-saving module 30 includes a water supply pipe 303, which is connected to the water tank 301, and the water supply pipe 303 is used to connect to an external water source.

[0037] In practical applications, when the energy-saving module 30 is working for a long time, the liquid medium (water) in the water tank 301 is continuously consumed. In order to avoid affecting the normal operation of the energy-saving module 30, it is necessary to replenish the liquid medium (water) in the water tank 301. Therefore, a water supply pipe 303 is provided. The water supply pipe 303 is connected to an external water source, such as a faucet. The external water source replenishes the liquid medium (water) in the water tank 301 through the water supply pipe 303 to ensure that the energy-saving module 30 can work normally.

[0038] Please refer to it again. Figure 2The energy-saving module 30 includes a switch 304, which is connected to the water supply pipe 303 and located inside the water tank 301. The switch 304 is used to shut off the water supply pipe 303. An overflow port 3011 is provided on the top of the water tank 301.

[0039] In practical applications, the water supply pipe 303 is connected to a switch 304, and the switch 304 can be located inside the water tank 301. When an external water source fills the water tank 301 with liquid medium (water) through the water supply pipe 303, the switch 304 senses that the water tank 301 is full and immediately shuts off the water supply pipe 303 to prevent the liquid medium (water) in the water tank 301 from overflowing, causing water waste and environmental pollution.

[0040] Meanwhile, an overflow port 3011 can be opened on the top of the water tank 301. When the liquid medium (water) in the water tank 301 is full, the excess liquid medium (water) can flow out through the overflow port 3011 to avoid the liquid medium (water) from overflowing and causing environmental pollution.

[0041] It should be noted that the switch 304 can adopt a structure such as a float switch, and this application does not limit it in this regard.

[0042] Please refer to it again. Figure 2 The energy-saving module 30 also includes a water pump 305, which is connected to the water outlet pipe 302. The water pump 305 is used to drive the liquid in the water tank 301 to flow to the water outlet pipe 302.

[0043] In practical applications, to accelerate the flow of the liquid medium (water), a water pump 305 can be installed. The water pump 305 provides power to make the liquid medium (water) in the water tank 301 flow to the outlet pipe 302 more quickly, effectively promoting the circulation of the liquid medium (water). This allows for faster heat absorption from the condenser 20, accelerating the cooling effect of the cooling coil 201. The water pump 305 can be any other device with similar function, and this application does not limit its use.

[0044] It is understandable that the device may also omit the water pump 305 and instead place the water tank 301 above the condenser 20, allowing the liquid medium (water) in the water tank 301 to flow to the outlet pipe 302 by gravity, thus achieving a similar effect.

[0045] Please see Figure 4 The energy-saving module 30 also includes a return pipe 306, which is connected to the water tank 301. The return pipe 306 has a return port 3061, which is located at the bottom of the condenser 20. The return port 3061 is used to collect water from the outer surface of the condenser 20.

[0046] In practical applications, when the second pipe 3022 sprays water onto the outer surface of the condenser 20, the water will fall off the condenser 20 after flowing over its outer surface. In order to save water resources and prevent the water falling from the condenser 20 from overflowing and affecting the environment, this application provides a return pipe 306 on one side of the condenser 20. The return port 3061 of the return pipe 306 is located at the bottom of the condenser 20 to collect the water falling off the condenser 20 and return it to the water tank 301 to replenish the liquid medium (water) in the water tank 301.

[0047] Please see Figure 5 The refrigeration device 40 includes an evaporator 401, which has a flow channel inside. The flow channel is connected to the cooling coil 201, and the refrigerant flows between the flow channel and the cooling coil 201 in sequence to achieve the conversion between gaseous and liquid states.

[0048] Please refer to it again. Figure 4 The refrigeration device 40 also includes a condensate pipe 402, which is connected to the water tank 301. The condensate pipe 402 is used to collect the condensate formed on the evaporator 401.

[0049] It should be noted that the refrigerant is in a low-temperature liquid state when it flows through the evaporator 401. Therefore, the surface temperature of the evaporator 401 is lower than the external ambient temperature. When the outside air comes into contact with the surface of the evaporator 401, it liquefies and forms condensate.

[0050] In order to collect condensate, this application provides a condensate pipe 402, which can be set below the evaporator 401 to facilitate the collection of condensate formed on the evaporator 401, and then guide the condensate to the water tank 301 to replenish the liquid medium (water) in the water tank 301. On the one hand, it saves water resources, and on the other hand, the condensate temperature is low, which can reduce the temperature of the liquid medium (water) and achieve a better cooling effect.

[0051] Please see Figure 6 The water outlet pipe 302 includes multiple third pipes 3023, which are connected to the condenser 20. The multiple third pipes 3023 are arranged at intervals along the height direction of the condenser 20. The third pipes 3023 are used to cool the cooling coil 201.

[0052] In some other embodiments, the water outlet pipe 302 can also achieve the cooling effect in other ways. For example, the water outlet pipe 302 includes multiple third pipes 3023. Along the height direction of the condenser 20, the multiple third pipes 3023 can be inserted into the condenser 20 in sequence at intervals. The multiple third pipes 3023 simultaneously cool the cooling coil 201, which greatly improves the cooling effect.

[0053] Please refer to it again. Figure 6Along the height of the condenser 20, the third pipe 3023 and the cooling coil 201 are alternately arranged. In practical applications, the condenser 20 can form multiple sequentially connected cooling coils 201 along the height direction. A third pipe 3023 is arranged between two adjacent cooling coils 201. That is to say, each cooling coil 201 has a third pipe 3023 on both sides. The third pipes 3023 on both sides cool the cooling coil 201, which accelerates the heat dissipation efficiency of the cooling coil 201, allowing the refrigerant to dissipate heat and turn into a liquid state more quickly.

[0054] In one embodiment, the third pipe 3023 can be attached to the cooling coil 201 to achieve heat exchange through heat transfer, thereby achieving a cooling effect. In this way, the liquid medium (water) in the third pipe 3023 does not flow out, protecting the environment and saving water resources.

[0055] In one embodiment, the third pipe 3023 has a water outlet 30221 on the side facing the cooling coil 201. The third pipe 3023 sprays liquid medium (water) onto the outer surface of the cooling coil 201. The flow of liquid medium (water) carries away the heat of the cooling coil 201, achieving a cooling effect. In this way, the liquid medium (water) can directly contact the outer surface of the cooling coil 201, reducing the heat transfer medium and enhancing the heat dissipation effect.

[0056] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0057] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

[0058] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0059] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
