Usually, this condensate will be collected through the water collection pan at the bottom of the fan and discharged through the drain pipe, resulting in a large waste of condensate resources. Utility Model Content

[0004] In view of this, the present invention provides a condensate recovery and utilization system for central air conditioning to solve the problem of a large amount of condensate water wasting resources during the use of central air conditioning.

The cold radiant water receiving tray is provided with an overflow branch pipe, which is connected to the overflow pipe.

[0009] Optionally, the atomizing structure includes an atomizing container and an atomizing generator. The atomizing container includes a second inlet and a second outlet. The second inlet is connected to the liquid outlet pipeline, and the second outlet is connected to the indoor air supply duct through an atomizing channel. The atomizing generator is disposed inside the atomizing container.

[0010] Optionally, the atomizer is a piezoelectric ceramic.

[0011] Optionally, the impurity removal structure includes: The filtration structure includes a first filter tank and a second filter tank; A disinfection structure, located downstream of the filtration structure, includes an ultraviolet disinfector.

[0012] Optionally, a liquid level sensor is installed inside the water storage container.

[0013] Optionally, the water storage container is provided with a water inlet, which is connected to an external water source through a water inlet pipe, and the water inlet pipe is provided with a water inlet valve.

[0014] Optionally, a liquid pump is installed on the delivery pipe, and a humidifying pump is installed on the liquid outlet pipe.

[0015] Beneficial effects: 1. The condensate recovery and utilization system for central air conditioning provided by this utility model includes: a conveying pipe, a radiant cooling unit, a water storage container, and a humidification unit. One end of the conveying pipe is connected to the condensate pan of the central air conditioning system. The radiant cooling unit is located downstream of the conveying pipe and includes a first inlet and a first outlet, with the first inlet connected to the other end of the conveying pipe. The water storage container includes a liquid inlet and a liquid outlet, with the first outlet connected to the liquid inlet. The humidification unit includes a liquid outlet pipe, and a purification structure and an atomizing structure disposed on the liquid outlet pipe, with the outlet end of the atomizing structure connected to the indoor air supply duct of the central air conditioning system.

[0016] During summer operation, the condensate in the central air conditioning system's condensate pan has cooling capacity. The condensate is drained from the pan via a delivery pipe and flows through the delivery pipe into the radiant cooling unit via the first inlet. Heat exchange occurs between the condensate and the radiant cooling unit, providing auxiliary cooling to the room. The condensate then flows through the first outlet and inlet into a storage container. During winter operation, the condensate in the storage container flows along the outlet pipe and passes through a purification structure before entering the atomizing structure. The atomizing structure converts the condensate into atomized gas, which enters the indoor air duct through the outlet and travels with the hot air in the duct to humidify the indoor environment and improve indoor air comfort.

[0017] Therefore, the condensate recovery and utilization system provided by this utility model can use the cooling capacity of condensate for auxiliary cooling in summer through the cold radiation unit, reducing the waste of cooling capacity, and can also use condensate to humidify the room in winter through the atomization unit, which greatly reduces the waste of condensate resources.

[0018] 2. The condensate recovery and utilization system for central air conditioning provided by this utility model includes a radiant cooling coil. Along the flow direction of the condensate, one end of the radiant cooling coil has a first inlet, and the other end has a first outlet. The condensate flows within the radiant cooling coil, where heat exchange occurs. The radiant cooling coil radiates cooling energy into the room for auxiliary cooling. After the heat exchange is complete, the condensate is discharged through the first outlet into a storage container for storage.

[0019] 3. The condensate recovery and utilization system for central air conditioning provided by this utility model has a discharge pipe connected to the first outlet, which is connected to the liquid inlet. The discharge pipe can be arranged according to the position of the radiant coil and the water storage container, improving the flexibility of the water storage container's placement.

[0020] 4. The condensate recovery and utilization system for central air conditioning provided by this utility model further includes a condensate drip tray in the radiant cooling unit, which is located below the radiant cooling coil. Considering that condensation may occur when the radiant cooling coil comes into contact with the air, the condensate drip tray can collect the condensate dripping from the radiant cooling coil, thereby preventing the condensate from dripping directly onto the room or the building ceiling.

[0021] The water storage container is equipped with an overflow port, which is connected to an overflow pipe. The radiant cooling water tray is equipped with an overflow branch pipe, which is connected to the overflow pipe. When there is too much condensate in the water storage container, the condensate will enter the overflow pipe through the overflow port and then be discharged into the drain pipe. When there is too much condensate in the radiant cooling water tray, the condensate in the radiant cooling water tray can enter the overflow pipe through the overflow branch pipe. If the liquid in the water storage container is insufficient, the water in the radiant cooling water tray can enter the water storage container through the overflow pipe and overflow port. If the liquid in the water storage container is excessive, the water in the radiant cooling water tray will directly enter the drain pipe and be discharged.

[0022] 5. The condensate recovery and utilization system for central air conditioning provided by this utility model includes an atomizing structure comprising an atomizing container and an atomizing generator. The atomizing container includes a second inlet and a second outlet. The second inlet is connected to a liquid outlet pipe, and the second outlet is connected to an indoor air supply duct through an atomizing channel. The atomizing generator is disposed inside the atomizing container. The atomizing container can receive clean condensate after impurity removal. When humidification is required, the atomizing generator operates, converting the condensate in the atomizing container into atomized gas. The atomized gas enters the indoor air supply duct through the second outlet and the atomizing channel, where it mixes with hot air and enters the room together.

[0023] 6. The condensate recovery and utilization system for central air conditioning provided by this utility model uses a piezoelectric ceramic as the atomizer. When energized, the piezoelectric ceramic generates tiny, high-frequency mechanical vibrations, which exert force on the condensate in the atomizing container, causing the condensate to break into tiny droplets. The droplets gradually fill the atomizing container and are discharged into the atomizing channel through the second outlet.

[0024] 7. The condensate recovery and utilization system for central air conditioning provided by this utility model includes a filtration structure and a disinfection structure. The filtration structure includes a first filter tank and a second filter tank. The disinfection structure is located downstream of the filtration structure and includes an ultraviolet sterilizer. The filtration structure can filter impurities in the condensate, and the disinfection structure can disinfect the condensate. Specifically, the condensate passes sequentially through the first filter tank, the second filter tank, and the ultraviolet sterilizer, so that the clean and sterile condensate enters the atomizing container.

[0025] 8. The condensate recovery and utilization system for central air conditioning provided by this utility model includes a liquid level sensor installed in the water storage container. The liquid level sensor can be used to detect the amount of liquid stored in the water storage container. In summer, this allows excess condensate to be drained from the water storage container when the liquid level is high. In winter, this allows water to be added to the water storage container when the liquid level is low, ensuring that atomized humidification can be performed.

[0026] 9. The condensate recovery and utilization system for central air conditioning provided by this utility model has a water inlet on the water storage container, which is connected to an external water source through a water supply pipe, and a water supply valve is installed on the water supply pipe. In winter, when the liquid level in the water storage container is insufficient, the water supply valve is opened, and external water enters the water storage container through the water supply pipe and the water inlet.

[0027] 10. The condensate recovery and utilization system for central air conditioning provided by this utility model includes a liquid pump installed on the delivery pipe and a humidifying pump installed on the outlet pipe. The liquid pump provides power to the condensate in the delivery pipe, facilitating its flow within the cold radiant unit. When humidification is required, the humidifying pump provides power to the water flow in the outlet pipe, allowing the water to pass through a purification structure and enter the atomizing structure.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a condensate recovery and utilization system for central air conditioning, including: a delivery pipe 1, a cold radiation unit 3, a water storage container 4, and a humidification unit.

[0033] One end of the delivery pipe 1 is connected to the condensate pan 201 of the central air conditioner. The condensate pan 201 can be the condensate pan 201 on the indoor unit 2.

[0034] The cold radiation unit 3 is located downstream of the conveying pipe 1 and includes a first inlet 31 and a first outlet 32. The first inlet 31 is connected to the other end of the conveying pipe 1.

[0035] The water storage container 4 includes an inlet 41 and an outlet 42, with the first outlet 32 ​​connected to the inlet 41.

[0036] The humidification unit includes a liquid outlet pipe 51, a cleanup structure 53 and an atomizing structure 52 installed on the liquid outlet pipe 51, and the outlet end of the atomizing structure 52 is connected to the indoor air supply pipe 202 of the central air conditioner.

[0037] During summer operation, the condensate in the central air conditioning condensate pan 201 has cooling capacity, typically at a temperature of 10°C to 20°C, and can serve as a cold source for radiant cooling. The condensate is discharged from the condensate pan 201 via the delivery pipe 1 and flows through the first inlet 31 into the radiant cooling unit 3. Heat exchange occurs between the condensate and the radiant cooling unit 3, providing auxiliary cooling to the room. The condensate then flows through the first outlet 32 ​​and the liquid inlet 41 into the storage container 4. During winter operation, the condensate in the storage container 4 flows along the liquid outlet pipe 51 and passes through the impurity removal structure 53 into the atomizing structure 52. The atomizing structure 52 converts the condensate into atomized gas, which enters the indoor air supply duct 202 through the outlet end and travels with the hot air in the duct to humidify the indoor environment and improve indoor air comfort.

[0038] It should be noted that humidification is generally not required in summer, so the condensate can be stored in water storage container 4 for later use.

[0039] Therefore, the condensate recovery and utilization system provided by this utility model can use the cooling capacity of the condensate to assist in cooling in summer through the cold radiation unit 3, reducing the waste of cooling capacity. It can also use the condensate to humidify the room in winter through the atomization unit, which greatly reduces the waste of condensate resources.

[0040] like Figure 2 and Figure 3 As shown, in this embodiment, the cold radiation unit 3 includes a cold radiation coil 33. Along the flow direction of the condensate, one end of the cold radiation coil 33 is provided with a first inlet 31, and the other end is provided with a first outlet 32. The condensate flows inside the cold radiation coil 33, and heat exchange occurs between the condensate and the cold radiation coil 33. The cold radiation coil 33 radiates cold energy into the room for auxiliary cooling. After the heat exchange is completed, the condensate is discharged into the water storage container 4 through the first outlet 32 ​​for storage.

[0041] The radiant cooling coil 33 can be made of copper to enhance heat exchange. The selection of the radiant cooling coil 33 can be determined according to the actual situation and is not limited here. An insulation layer can be applied to the outside of the delivery pipe 1 to avoid heat loss and prevent condensation.

[0042] like Figure 2 As shown, the first outlet 32 ​​is connected to a discharge pipe, which is connected to the liquid inlet 41. The discharge pipe can be arranged according to the positions of the cold radiant coil 33 and the water storage container 4, thereby improving the flexibility of the arrangement of the water storage container 4.

[0043] In one alternative embodiment, the water storage container 4 can be a sealed water storage tank. The outer wall of the sealed water storage tank is provided with an inlet 41 and an outlet 42. The discharge pipe can be extended into the water storage container 4 through the inlet 41 to improve the sealing performance.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, the cold radiation unit 3 also includes a cold radiation water receiving tray 34, which is disposed below the cold radiation coil 33. Considering that condensation may occur when the cold radiation coil 33 comes into contact with the air, the cold radiation water receiving tray 34 can collect the condensate dripping from the cold radiation coil 33, thereby preventing the condensate from dripping directly onto the room or the building ceiling.

[0045] The water storage container 4 is equipped with an overflow port 43, which is connected to an overflow pipe 431. The radiant cooling water receiving pan 34 is equipped with an overflow branch pipe 341, which is connected to the overflow pipe 431. When there is too much condensate in the water storage container 4, the condensate will enter the overflow pipe 431 through the overflow port 43, and then be discharged into the drain pipe 6. When there is too much condensate in the radiant cooling water receiving pan 34, the condensate in the radiant cooling water receiving pan 34 can enter the overflow pipe 431 through the overflow branch pipe 341. If the liquid in the water storage container 4 is insufficient, the water in the radiant cooling water receiving pan 34 can enter the water storage container 4 through the overflow pipe 431 and the overflow port 43. If the liquid in the water storage container 4 is excessive, the water in the radiant cooling water receiving pan 34 will directly enter the drain pipe 6 for discharge.

[0046] In one optional embodiment, an electric switch valve can be installed on the drain pipe 6. When the water storage container 4 is insufficient, the electric switch valve closes, and the condensate in the cold radiation water receiving pan 34 can enter the water storage container 4 through the overflow pipe 431 and the overflow port 43. If the water outflow from the water storage container 4 is excessive, the electric switch valve opens, and the water overflowing from the water storage container 4 and the water in the cold radiation water receiving pan 34 can be directly discharged from the drain pipe 6.

[0047] In one alternative implementation, the downstream of the drain pipe 6 can be connected to a water point such as a toilet or mop sink, further conserving water resources.

[0048] like Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, the atomizing structure 52 includes an atomizing container 522 and an atomizing generator 523. The atomizing container 522 includes a second inlet and a second outlet. The second inlet is connected to the liquid outlet pipe 51, and the second outlet is connected to the indoor air supply duct 202 through the atomizing channel 521. The atomizing generator 523 is disposed inside the atomizing container 522. The atomizing container 522 can be filled with clean condensate after impurity removal. When humidification is required, the atomizing generator 523 operates, converting the condensate in the atomizing container 522 into atomized gas. The atomized gas enters the indoor air supply duct 202 through the second outlet and the atomizing channel 521, where it mixes with hot air and enters the room together.

[0049] In one embodiment, the second outlet may be equipped with a fan 524, which blows the liquid mist in the atomizing container 522 into the atomizing channel 521, and then into the indoor air supply duct 202 to accelerate the humidification efficiency.

[0050] In one embodiment, a humidifying pump 511 is provided on the liquid outlet pipe 51. The humidifying pump 511 is located between the water storage container 4 and the impurity removal structure 53. The humidifying pump 511 can provide power for the flow of condensate in the liquid outlet pipe 51.

[0051] like Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the atomizer 523 is a piezoelectric ceramic. When energized, the piezoelectric ceramic generates tiny, high-frequency mechanical vibrations, which exert force on the condensate in the atomizing container 522, causing the condensate to break into tiny droplets. The droplets gradually fill the atomizing container 522 and are discharged into the atomizing channel 521 through the second outlet.

[0052] like Figure 2 , Figure 4 and Figure 6 As shown, in this embodiment, the impurity removal structure 53 includes a filtration structure and a disinfection structure. The filtration structure includes a first filter tank 532 and a second filter tank 533. The disinfection structure is located downstream of the filtration structure and includes an ultraviolet sterilizer 54. The filtration structure can filter impurities in the condensate, and the disinfection structure can disinfect the condensate. Specifically, the condensate passes sequentially through the first filter tank 532, the second filter tank 533, and the ultraviolet sterilizer 54, so that the clean and sterile condensate enters the atomizing container 522. The ultraviolet sterilizer 54 may include a disinfection chamber, an inlet, and an outlet. The condensate passes sequentially through the inlet, the disinfection chamber, and the outlet to complete the disinfection process. The filtered condensate is disinfected in the disinfection chamber using ultraviolet light with a wavelength of 254 nanometers. The specific structure of the ultraviolet sterilizer 54 can be found in common ultraviolet sterilizers and will not be described in detail here.

[0053] like Figure 2 , Figure 4 and Figure 6 As shown, in one optional embodiment, the impurity removal structure includes a filter box 531, a first filter tank 532 and a second filter tank 533 placed in the filter box, an outlet pipe 51 connected to the top opening of the first filter tank 532, a connecting pipe 534 provided between the bottom of the first filter tank 532 and the second filter tank 533, and the top opening of the second filter tank 533 communicating with the downstream of the outlet pipe 51. The first filter tank 532 contains a quartz sand filter element, and the second filter tank 533 contains an activated carbon filter element.

[0054] Condensate enters from the top of the first filter tank 532, and then passes through a quartz sand filter, a connecting pipe 534, and an activated carbon filter for filtration. Afterward, it flows downstream from the top opening of the second filter tank 533 to the outlet pipe 51, thus completing the filtration and impurity removal process. First, the quartz sand filter removes large particulate impurities, and then the activated carbon filter removes small molecule pollutants. This structure allows for graded impurity removal, improving the impurity removal effect.

[0055] like Figure 2 and Figure 7 As shown, in this embodiment, a liquid level sensor 45 is installed inside the water storage container 4. The liquid level sensor 45 can be used to detect the amount of liquid stored in the water storage container 4. In summer, this allows excess condensate to be drained from the water storage container 4 when the liquid level is high. In winter, it allows water to be added to the water storage container 4 when the liquid level is low, ensuring that atomized humidification can be performed. Figure 2 and Figure 7 As shown, in this embodiment, the water storage container 4 is equipped with a water inlet, which is connected to an external water source via a water supply pipe 44. A water supply valve 441 is installed on the water supply pipe 44. In winter, when the liquid level in the water storage container 4 is insufficient, the water supply valve 441 opens, allowing external water to enter the water storage container 4 through the water supply pipe 44 and the water inlet. Figure 1 As shown, in this embodiment, a liquid pump 11 is installed on the delivery pipe 1. The liquid pump 11 can provide power for the condensate in the delivery pipe 1, so that the condensate can flow in the cold radiation unit 3. The liquid pump 11 can be a booster pump.

[0056] like Figure 1 and Figure 2As shown, in this embodiment, the condensate recovery and utilization system also includes a control box 7. The control box 7 is connected to the electrical equipment of the condensate recovery and utilization system and is used to control the operation of each electrical device. For example, the control box 7 is electrically connected to the liquid pump 11, the atomizer 523, the humidifier pump 511, the liquid level sensor 45, and the water supply valve 441. In addition, a humidity sensor 203 can be installed on the indoor unit 2. The humidity sensor 203 is electrically connected to the control box 7. A drain valve 61 is installed on the drain pipe 6. The drain valve 61 is an electrically operated valve and is electrically connected to the control box 7.

[0057] For example, the liquid level sensor 45 can detect the liquid level information in the water storage container 4. The control box 7 controls the opening and closing of the water replenishment valve 441 based on the liquid level information. In winter, when the liquid level information indicates that the water storage in the water storage container 4 is insufficient, the control box 7 controls the water replenishment valve 441 to open and replenish the water tank with water from an external water source.

[0058] Specifically, in summer, if the liquid level detected by the liquid level sensor 45 reaches or exceeds the first preset height, the drain valve 61 of the drain pipe 6 is opened. The first preset height can be the height corresponding to the overflow port 43 or a height lower than the overflow port 43, depending on the actual situation. In winter, if the liquid level detected by the liquid level sensor 45 reaches or falls below the second preset height, the water supply valve 441 is opened, and water is supplied to the water storage container 4 through the water supply pipe 44.

[0059] The humidity sensor 203 can be used to detect indoor humidity information. The control box 7 controls the humidification unit to work based on the humidity information. In winter, when the humidity information indicates that the indoor humidity is too low, the control box 7 controls the humidification pump 511 and the atomizer 523 to work.

[0060] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
