Description

Technical Field

[0001] This utility model relates to the field of condenser equipment technology, specifically a split air conditioner condensate water recovery and utilization system. Background Technology

[0002] An air conditioner is an air temperature regulating device, mainly composed of a compressor, condenser, evaporator, high-pressure exhaust pipe, and low-pressure return pipe. The air conditioner condenser is often used to cool the high-temperature outdoor gas. During summer operation, air conditioners produce a large amount of condensate. When the outdoor temperature is too high, the condensing temperature rises, the heat exchange efficiency between the condenser and the outside decreases, the exhaust temperature and pressure of the air conditioner compressor rise, the compressor load increases, and the power increases, leading to a decrease in the air conditioner's energy efficiency ratio. In severe cases, this may cause the compressor's protector to trip, shutting down the air conditioner and affecting user experience. Prolonged operation in such a high-temperature environment can easily cause the compressor motor coils to overheat, reducing their lifespan and eventually leading to the burnout of the compressor motor coils. Therefore, Chinese Patent CN202835594U discloses an air conditioner condenser cooling device, including an atomizing controller. The atomizing controller includes a housing, which is divided into upper and lower parts. The upper part is a water storage tank, and the lower part is an electrical compartment. The water storage tank and the electrical compartment are separated by a partition. The upper part of the water storage tank has a water inlet, which is connected to one end of a water inlet hose. The other end of the water inlet hose is connected to the condensate drain outlet of the air conditioner evaporator. The upper part of the water storage tank also has an overflow outlet, which is connected to an overflow connection pipe. The electrical compartment contains a solenoid valve. The partition has an opening, through which the inlet of the solenoid valve passes and connects to the upper water storage tank. The outlet of the solenoid valve is connected to one end of an outlet connection pipe, and the other end of the outlet connection pipe is connected to an atomizing nozzle. The atomizing nozzle is fixedly installed on the outdoor unit of the air conditioner and is aimed at the condenser tube of the air conditioner condenser. This utility model improves the heat exchange efficiency between the condenser and the outside environment, reduces the load on the air conditioner compressor, improves the air conditioner's energy efficiency ratio, saves energy by more than 2.8%, and extends the service life of the air conditioner compressor.

[0003] However, in practical applications, the above-mentioned device still has the following shortcomings: due to the fixed position of the atomizing nozzle, the water mist sprayed onto the condenser is not uniform, resulting in excessive water mist condensing and dripping at the position directly in front of the atomizing nozzle, while there is no water mist at the position far away from the atomizing nozzle, and the cooling effect is not ideal; in addition, the water condensed from large droplets flowing out of the air conditioner outdoor unit can easily corrode the bolts used to install the air conditioner outdoor unit, posing a certain safety hazard. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a split-type air conditioner condensate water recovery and utilization system that can uniformly cool the condenser, achieve better cooling effect, and avoid the occurrence of large droplets of condensate dripping, making it safer and more reliable to use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A split-type air conditioner condensate water recovery and utilization system includes an outdoor unit, a condenser installed inside the outdoor unit, and an indoor evaporator installed indoors. The indoor evaporator is equipped with a drain pipe. The system is characterized by: a water collection box fixed inside the outdoor unit; a main mist outlet pipe extending into the water collection box at its top; a horizontal pipe connected to the bottom of the main mist outlet pipe; multiple mist outlet branch pipes whose tops are connected to the horizontal pipe; and an ultrasonic atomizer installed at the bottom inner side of the water collection box. Each mist outlet branch pipe has at least two atomizing tubes, and the multiple atomizing tubes are arranged in a matrix. An overflow pipe is provided on one side of the middle section, with one end of the overflow pipe extending out of the outdoor unit of the air conditioner. The outlet end of the connecting water pipe is connected to the water collection box. A mist pump is provided on the main mist outlet pipe. The mist outlet end of the ultrasonic atomizer is positioned upwards. The water inlet end of the overflow pipe is higher than the mist outlet end of the ultrasonic atomizer but lower than the mist inlet end of the main mist outlet pipe. The top end of the main mist outlet pipe extends to above the liquid surface of the water collection box. The output end of the atomizing pipe is positioned directly opposite the condenser. Both ends of the horizontal pipe and the bottom end of the mist outlet branch pipe are sealed. The outlet end of the connecting water pipe is staggered from the mist inlet end of the main mist outlet pipe.

[0007] Furthermore, the height difference between the mist outlet end of the ultrasonic atomizer and the water inlet end of the overflow pipe is in the range of 45-55 mm.

[0008] Furthermore, the height difference between the top of the main mist outlet pipe and the top wall of the water collection box is 5-10mm, and the top of the main mist outlet pipe is higher than the water inlet end of the overflow pipe.

[0009] Furthermore, a drain pipe connecting to the interior of the air conditioner is provided on one side of the bottom of the outdoor unit.

[0010] Furthermore, it also includes a level gauge installed in the water collection box, one end of which is connected to a water inlet pipe inside the water collection box, a controller connected to a power supply, and a temperature sensor installed on the condenser. The water outlet height of the water inlet pipe is the same as that of the overflow pipe. A water inlet valve is installed on the water inlet pipe. The mist pump, ultrasonic atomizer, level gauge, water inlet valve, and temperature sensor are all electrically connected to the controller.

[0011] The beneficial effects of this utility model are:

[0012] In practical applications, condensate from the indoor evaporator is collected in a water collection box via a connecting water pipe. Since the inlet of the overflow pipe is higher than the outlet of the ultrasonic atomizer but lower than the inlet of the main mist outlet pipe, the ultrasonic atomizer atomizes the water above the liquid surface in the collection box. The water mist above the liquid surface is extracted through the main mist outlet pipe and the mist pump, and then sprayed onto the condenser through a horizontal pipe, mist outlet branch pipes, and multiple atomizing pipes arranged in a matrix, resulting in uniform cooling of the condenser. This invention provides uniform cooling of the condenser, resulting in better cooling performance and preventing large droplets from condensing and dripping, making it safer and more reliable to use.

[0017] like Figure 1 and Figure 2As shown, a split-type air conditioner condensate water recovery and utilization system includes an outdoor unit 1, a condenser 2 installed inside the outdoor unit 1, and an indoor evaporator installed indoors. The indoor evaporator is equipped with a connecting water pipe 3 for drainage. The system is characterized by: a water collection box 4 fixed inside the outdoor unit 1; a main mist outlet pipe 5 extending into the water collection box 4 at its top; a horizontal pipe 6 connected to the bottom of the main mist outlet pipe 5; multiple mist outlet branch pipes 7 whose tops are connected to the horizontal pipe 6; an ultrasonic atomizer 8 installed at the bottom inner side of the water collection box 4; each mist outlet branch pipe 7 having at least two atomizing pipes 9; and the multiple atomizing pipes 9 arranged in a matrix. The water collection box 4 contains... An overflow pipe 10 is provided on one side of the unit, with one end of the overflow pipe 10 extending out of the outdoor unit 1 of the air conditioner. The outlet end of the connecting water pipe 3 is connected to the water collection box 4. A mist pump 11 is provided on the main mist outlet pipe 5. The mist outlet end of the ultrasonic atomizer 8 is set upwards. The water inlet end of the overflow pipe 10 is higher than the mist outlet end of the ultrasonic atomizer 8 and lower than the mist inlet end of the main mist outlet pipe 5. The top end of the main mist outlet pipe 5 extends to above the liquid surface of the water collection box 4. The output end of the atomizing pipe 9 is set directly opposite the condenser 2. Both ends of the transverse pipe 6 and the bottom end of the mist outlet branch pipe 7 are sealed. The outlet end of the connecting water pipe 3 is staggered from the mist inlet end of the main mist outlet pipe 5.

[0018] The condensate generated by the indoor evaporator is collected in the water collection box 4 by connecting water pipe 3. Since the water inlet of the overflow pipe 10 is higher than the mist outlet of the ultrasonic atomizer 8 and lower than the mist inlet of the main mist outlet pipe 5, the ultrasonic atomizer atomizes the water above the liquid surface in the water collection box 4. The water mist above the liquid surface is extracted by the main mist outlet pipe 5 and the mist pump 11, and sprayed onto the condenser through the horizontal pipe 6, the mist outlet branch pipe 7 and the multiple atomizing pipes 9 distributed in a matrix, so that the condenser is cooled evenly. This utility model can cool the condenser evenly, with better cooling effect, and can also avoid the situation of large liquid droplets condensing and dripping water, making it safer and more reliable to use.

[0019] like Figure 1 and Figure 2 As shown, the height difference between the mist outlet end of the ultrasonic atomizer 8 and the water inlet end of the overflow pipe 10 is 45-55mm. In this embodiment, when the height difference between the mist outlet end of the ultrasonic atomizer 8 and the water inlet end of the overflow pipe 10 is 45-55mm, the liquid level in the water collection box 4 is maintained at 45-55mm above the mist outlet plate of the ultrasonic atomizer 8, thus ensuring the misting effect of the ultrasonic atomizer 8.

[0020] like Figure 1 and Figure 2As shown, the height difference between the top of the main mist outlet pipe 5 and the top wall of the water collection box 4 is 5-10mm, and the top of the main mist outlet pipe 5 is higher than the water inlet end of the overflow pipe 10. In this embodiment, when the height difference between the top of the main mist outlet pipe 5 and the top wall of the water collection box 4 is 5-10mm, and the top of the main mist outlet pipe 5 is higher than the water inlet end of the overflow pipe 10, the main mist outlet pipe 5 can remove the water mist above the liquid surface through the mist pump 11, and no excess water will enter the main mist outlet pipe 5.

[0021] like Figure 1 and Figure 2 As shown, a drain pipe 12 is provided on one side of the bottom of the outdoor unit 1, which connects to the interior of the outdoor unit 1. In this embodiment, when too much liquid condensed on the condenser 2 drips down, it can be discharged from the drain pipe 12. The lowest atomizing pipe 9 is higher than the water inlet end of the drain pipe 12.

[0022] like Figure 1 and Figure 2 As shown, it also includes a level gauge 14 installed in the water collection box 4, one end of which is connected to a water inlet pipe 13 inside the water collection box 4, a controller connected to a power supply, and a temperature sensor installed on the condenser 2. The water outlet height of the water inlet pipe 13 is the same as that of the overflow pipe 10. A water inlet valve is provided on the water inlet pipe 13. The mist pump 11, ultrasonic atomizer 8, level gauge 14, water inlet valve, and temperature sensor are all electrically connected to the controller. In this embodiment, during use, the outer end of the water inlet pipe 13 is connected to a tap water pipe. When the water inlet pipe 3 is low, the level gauge 14 detects that the liquid level in the water collection box 4 is lower than a preset value, and the controller controls the water inlet valve to open, allowing tap water to replenish the water collection box 4. When the level gauge 14 detects that the liquid level in the water collection box 4 is sufficient, the controller controls the water inlet valve to close. When the temperature sensor detects that the temperature of the condenser 2 is too high, the controller controls the mist pump 11 and ultrasonic atomizer 8 to produce mist.

[0023] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by the spirit of this utility model.
