[0055] The intermediate connection mechanism includes a condensate booster pump 6 and a water-heating electromagnetic main valve 7. The two ends of the condensate booster pump 6 are respectively connected to the water outlet 102 and the water-heating electromagnetic main valve 7. When the water-heating electromagnetic main valve 7 is opened, the intermediate connection mechanism is in a connected state. When the water-heating electromagnetic main valve 7 is closed, the intermediate connection mechanism is in a disconnected state.

[0056] The water heater mechanism includes a first water heater 8, a second water heater 9, a third water heater 10, a first water heating solenoid valve 11, a second water heating solenoid valve 12, a third water heating solenoid valve 13, a fourth water heating solenoid valve 14, a fifth water heating solenoid valve 15, a sixth water heating solenoid valve 16, a water heater water outlet manifold 17 and a water outlet temperature detection unit 18.

[0057] The first water heater 8, the second water heater 9 and the third water heater 10 are connected in parallel, and one end of the first water heater 8, the second water heater 9 and the third water heater 10 connected in parallel is connected to the water heater electromagnetic main valve 7, and the other end of the first water heater 8, the second water heater 9 and the third water heater 10 connected in parallel is provided with a water heater water outlet manifold 17. Each water heater can be used to heat the air supply of the air conditioner, and the cooling water heated by the water heater air supply can enter the water heater water outlet manifold 17 to discharge the water heater circulation application device of the high-temperature condensed water.

[0058] The first water-heating solenoid valve 11 is arranged at one end of the water outlet of the first water heater 8. The second water-heating solenoid valve 12 and the third water-heating solenoid valve 13 are respectively arranged at one end of the water inlet and one end of the water outlet of the second water heater 9. The fourth water-heating solenoid valve 14 is arranged at one end of the water inlet of the third water heater 10. The two ends of the fifth water-heating solenoid valve 15 are respectively connected to the pipe between the first water heater 8 and the first water-heating solenoid valve 11 and the pipe between the second water heater 9 and the second water-heating solenoid valve 12. The two ends of the sixth water-heating solenoid valve 16 are respectively connected to the pipe between the second water heater 9 and the third water-heating solenoid valve 13 and the pipe between the third water heater 10 and the fourth water-heating solenoid valve 14. The outlet water temperature detection unit 18 is installed on the water heater outlet manifold 17. The water inlet of the above-mentioned water heater refers to the side of the water heater adjacent to the water-heating solenoid main valve 7, and the water outlet of the water heater refers to the side of the water heater adjacent to the water heater outlet manifold 17.

[0059] By controlling the on and off of the first water heating solenoid valve 11, the second water heating solenoid valve 12, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14, the fifth water heating solenoid valve 15 and the sixth water heating solenoid valve 16, the working state of each water heater (i.e. whether to heat the air supply to the air-conditioning outlet) can be controlled, thereby adjusting the temperature and humidity of the air-conditioning supply outlet.

[0060] The boiler utilization mechanism includes a boiler pipeline electromagnetic valve 19, a softened water tank 20, a boiler water inlet pump 21 and a boiler 22. The boiler pipeline electromagnetic valve 19, the softened water tank 20, the boiler water inlet pump 21 and the boiler 22 are connected in sequence. The boiler pipeline electromagnetic valve 19 is connected to the end of the water heater outlet manifold 17. The condensed water flowing out of the water heater outlet manifold 17 has residual temperature and is softened water, so it can enter the boiler 22 for utilization.

[0061] The condensate return mechanism includes a return pipe 23 and a return solenoid valve 24. The two ends of the return pipe 23 are respectively connected to the end of the water heater outlet manifold 17 and the return port 105. The return solenoid valve 24 is installed on the return pipe 23. When the temperature of the condensate flowing out of the water heater outlet manifold 17 is high, it can flow back to the condensate storage tank 1, thereby replenishing the condensate in the condensate storage tank 1. The condensate return mechanism is arranged in parallel with the boiler utilization mechanism to determine whether to enter the condensate return mechanism or the boiler utilization mechanism according to the temperature of the condensate flowing out of the water heater outlet manifold 17.

[0062] The water heater circulation application device for high-temperature condensate water disclosed in the present invention stores condensate water in a storage mechanism, and the condensate water can be supplied to the water heater mechanism through an intermediate connecting mechanism, and controlled to heat the air supply for air conditioning by supplying water to each water heater of the water heater mechanism. Moreover, the condensate water after being used by the water heater can flow back to the condensate storage tank 1 or the boiler 22, effectively ensuring the collection and utilization of high-temperature condensate water.

[0063] In one embodiment of the water heater circulation application device of high-temperature condensate water disclosed in the present invention, in order to improve the utilization efficiency of high-temperature condensate water, the sewage outlet 103 and the exhaust outlet 104 are respectively located at two ends of the condensate water storage tank 1.

[0064] In one embodiment of the water heater circulation application device of high-temperature condensate water disclosed in the present invention, in order to improve the utilization efficiency of high-temperature condensate water, the distance between the water inlet 101 and the storage filter unit 2 along the central axis direction of the condensate storage tank 1 is greater than the distance between the water outlet 102 and the storage filter unit 2 along the central axis direction of the condensate storage tank 1. The distance between the water inlet 102 and the storage filter unit 2 along the central axis direction of the condensate storage tank 1 is smaller than the distance between the return port 105 and the storage filter unit 2 along the central axis direction of the condensate storage tank 1, and the distance between the return port 105 and the storage filter unit 2 along the central axis direction of the condensate storage tank 1 is greater than the distance between the water outlet 102 and the storage filter unit 2 along the central axis direction of the condensate storage tank 1.

[0065] In one embodiment of the water heater circulation application device of high-temperature condensate water disclosed in the present invention, in order to improve the utilization efficiency of high-temperature condensate water, the storage tank water level detection unit 4 is located below the storage tank temperature detection unit 5 .

[0066] Furthermore, the storage tank water level detection unit 4 and the storage tank temperature detection unit 5 are both located above the water outlet 102 .

[0067] In one embodiment of the water heater circulation application device of the high-temperature condensate disclosed in the present invention, in order to improve the utilization efficiency of the high-temperature condensate, the storage mechanism further includes a silk-making reel condensate pump 25 and a power air-conditioning condensate pump 26. The silk-making reel condensate pump 25 and the power air-conditioning condensate pump 26 are connected to the water inlet 101 through a pipeline. In a specific implementation, the silk-making reel condensate pump 25 and the power air-conditioning condensate pump 26 can be arranged in parallel.

[0068] like Figure 2 As shown, the present disclosure also provides a water heater circulation application method of high-temperature condensate water based on the water heater circulation application device of the present disclosure, comprising the following steps:

[0069] It is determined whether the temperature and humidity value of the air supply outlet of the air conditioner is less than the preset temperature and humidity value and whether the temperature in the condensate storage tank 1 is higher than the output temperature. The output temperature may be 50°C, for example.

[0070] When the temperature and humidity values ​​of the air conditioning outlet are not less than the preset temperature and humidity values ​​and the temperature in the condensate storage tank 1 is lower than the output temperature, it means that the water heater circulation application device of the high-temperature condensate does not meet the conditions for heating the air conditioning outlet, and the condensate booster pump 6 can be turned off.

[0071] If the temperature and humidity value of the air-conditioning air supply outlet is less than the preset temperature and humidity value and the temperature in the condensate storage tank 1 is higher than the output temperature, it indicates that the water heater circulation application device of the high-temperature condensate meets the conditions for heating the air supply outlet of the air-conditioning, and the condensate booster pump 6 is turned on. At this time, it can be further judged whether the air flow in the air-conditioning box needs to be heated and whether the water level in the condensate storage tank 1 can meet the heating demand. Therefore, when the temperature and humidity value of the air-conditioning air supply outlet is less than the preset temperature and humidity value and the temperature in the condensate storage tank 1 is higher than the output temperature, the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is calculated, and the water level of the condensate storage tank 1 is obtained, so as to control the opening and closing of the water heating electromagnetic main valve 7 according to the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet and the water level of the condensate storage tank 1. By controlling the opening and closing of the water heating electromagnetic main valve 7, the on-off of the intermediate connecting mechanism can be controlled.

[0072] Specifically, the opening and closing of the water heating electromagnetic main valve is controlled according to the difference between the preset temperature value and the temperature value of the air supply outlet of the air conditioner and the water level of the condensate storage tank 1 as follows:

[0073] If the difference between the preset temperature value and the air supply outlet temperature of the air conditioner is less than 1.5°C and / or the water level of the condensate storage tank 1 is less than 1.6m, the water heating electromagnetic main valve 7 is closed.

[0074] When the difference between the preset temperature value and the air outlet temperature of the air conditioner is less than 1.5°C and / or the water level of the condensate storage tank 1 is less than 1.6m, it means that the air flow in the air conditioner does not need to be heated, or the water level of the condensate storage tank 1 is low. At this time, the water heating electromagnetic main valve 7 is closed to prevent condensate from entering the water heater mechanism.

[0075] If the difference between the preset temperature value and the temperature value of the air-conditioning supply air outlet is greater than 1.5°C and the water level of the condensate storage tank 1 is greater than 1.6m, the water heating electromagnetic main valve 7 is opened, and at least one of the first water heater 8, the second water heater 9 and the third water heater 10 is controlled to operate according to the difference between the preset temperature value and the temperature value of the air-conditioning supply air outlet and the water level of the condensate storage tank 1.

[0076] When the difference between the preset temperature value and the temperature value of the air supply outlet of the air conditioner is greater than 1.5°C and the water level of the condensate storage tank 1 is greater than 1.6m, it indicates that the air flow in the air conditioner needs to be heated and the water volume in the condensate storage tank 1 meets the output conditions. At this time, the water heating electromagnetic main valve 7 can be opened to allow the water in the condensate storage tank 1 to flow to each water heater, and the temperature of the air supply outlet of the air conditioner is adjusted by heating the air supply to the air conditioner outlet. The working states of the first water heater 8, the second water heater 9 and the third water heater 10 in the present disclosure can be flexibly selected according to actual needs.

[0077] In one embodiment of the water heater circulation application method of high-temperature condensate, at least one of the first water heater 8, the second water heater 9 and the third water heater 10 is controlled to work as follows according to the difference between the preset temperature value and the temperature value of the air supply outlet of the air conditioner and the water level of the condensate storage tank 1:

[0078] If the difference between the preset temperature value and the air supply outlet temperature of the air conditioner is greater than 7.5° C. and the water level of the condensate storage tank 1 is greater than 3 m, the fifth water heating solenoid valve 15 and the sixth water heating solenoid valve 16 are closed.

[0079] When the difference between the preset temperature value and the temperature value of the air supply outlet of the air conditioner is greater than 7.5°C and the water level of the condensate storage tank 1 is greater than 3m, it indicates that the air flow in the air conditioner box needs to be heated up greatly and the amount of water in the condensate storage tank 1 is sufficient. In order to make the high-temperature condensate quickly increase the air supply temperature of the air conditioner, close the fifth water heating solenoid valve 15 and the sixth water heating solenoid valve 16, and the high-temperature condensate passes through the water outlet 102, the condensate booster pump 6 and the water heating solenoid main valve 7 in turn, and enters the first water heater 8, the second water heater 9 and the third water heater 10 respectively, and heats the air supply of the air conditioner through the first water heater 8, the second water heater 9 and the third water heater 10. The water flowing out of the first water heater 8, the second water heater 9 and the third water heater 10 converges to the water heater outlet manifold 17 and leaves the water heater mechanism.

[0080] If the difference between the preset temperature value and the air supply outlet temperature of the air conditioner is greater than 7.5°C and the water level of the condensate storage tank 1 is less than 3m and greater than 1.7m, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14 and the fifth water heating solenoid valve 15 are closed.

[0081] When the difference between the preset temperature value and the temperature value of the air-conditioning air outlet is greater than 7.5°C and the water level of the condensate storage tank 1 is less than 3m and greater than 1.7m, it indicates that the temperature of the air-conditioning air outlet needs to be increased. In order to make full use of the high-temperature condensate to quickly increase the air-conditioning air supply temperature, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14 and the fifth water heating solenoid valve 15 are closed, and the high-temperature condensate passes through the water outlet 102, the condensate booster pump 6 and the water heating solenoid main valve 7 in turn, and enters the first water heater 8 and the second water heater 9 respectively. The high-temperature condensate entering the first water heater 8 is heated by the air-conditioning air supply and passes through the first water heating solenoid valve 11, and then merges into the water heater outlet manifold 17 and leaves the water heater mechanism. The high-temperature condensate entering the second water heater 9 is heated by the air conditioning supply air, and then passes through the sixth water heating solenoid valve 16 to enter the third water heater 10 to heat the air conditioning supply air. The water flowing out of the third water heater 10 converges to the water heater outlet manifold 17 and leaves the water heater mechanism.

[0082] If the difference between the preset temperature value and the air supply outlet temperature of the air conditioner is greater than 5°C and less than 7.5°C and the water level of the condensate storage tank 1 is greater than 1.7m, close the first water heating solenoid valve 11, the second water heating solenoid valve 12, the third water heating solenoid valve 13 and the fourth water heating solenoid valve 14.

[0083] When the difference between the preset temperature value and the temperature value of the air-conditioning air outlet is greater than 5°C and less than 7.5°C and the water level of the condensate storage tank 1 is greater than 1.7m, it indicates that the temperature of the air-conditioning air outlet does not need to be increased too much. In order to make full use of the high-temperature condensate to increase the air-conditioning air temperature, close the first water heating solenoid valve 11, the second water heating solenoid valve 12, the third water heating solenoid valve 13 and the fourth water heating solenoid valve 14. The high-temperature condensate passes through the water outlet 102, the condensate booster pump 6 and the water heating solenoid main valve 7 in turn, enters the first water heater 8 to heat the air-conditioning supply, leaves the first water heater 8, and enters the second water heater 9 and the third water heater 10 in turn to heat the air-conditioning supply. The water flowing out of the third water heater 10 flows to the water heater outlet manifold 17 and leaves the water heater mechanism.

[0084] If the difference between the preset temperature value and the air supply outlet temperature of the air conditioner is greater than 3°C and less than 5°C and the water level of the condensate storage tank 1 is greater than 1.7m, close the first water heating solenoid valve 11, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14 and the fifth water heating solenoid valve 15.

[0085] When the difference between the preset temperature value and the temperature value of the air-conditioning air outlet is greater than 3°C and less than 5°C and the water level of the condensate storage tank 1 is greater than 1.7m, it indicates that the temperature of the air-conditioning air outlet does not need to be increased much. In order to make full use of the high-temperature condensate to increase the air-conditioning air temperature, close the first water heating solenoid valve 11, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14 and the fifth water heating solenoid valve 15. The high-temperature condensate passes through the water outlet 102, the condensate booster pump 6 and the water heating solenoid main valve 7 in turn, enters the second water heater 9 to heat the air-conditioning air, and then enters the third water heater 10 to heat the air-conditioning air. The water flowing out of the third water heater 10 flows to the water heater outlet manifold 17 and leaves the water heater mechanism.

[0086] If the difference between the preset temperature value and the air supply outlet temperature of the air conditioner is greater than 1.5°C and less than 3°C and the water level of the condensate storage tank 1 is greater than 1.7m, close the second water heating solenoid valve 12, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14, the fifth water heating solenoid valve 15 and the sixth water heating solenoid valve 16.

[0087] When the difference between the preset temperature value and the temperature value of the air-conditioning air outlet is greater than 1.5°C and less than 3°C and the water level of the condensate storage tank 1 is greater than 1.7m, it indicates that the temperature of the air-conditioning air outlet needs to be increased less. In order to increase the air-conditioning air supply temperature, close the second water heating solenoid valve 12, the third water heating solenoid valve 13, the fourth water heating solenoid valve 14, the fifth water heating solenoid valve 15 and the sixth water heating solenoid valve 16. The high-temperature condensate passes through the water outlet 102, the condensate booster pump 6 and the water heating solenoid main valve 7 in turn, enters the first water heater 8 to heat the air-conditioning air supply, and the water flowing out of the first water heater 8 flows to the water heater outlet manifold 17 and leaves the water heater mechanism.

[0088] By using this method of controlling the operation of the first water heater 8, the second water heater 9 and the third water heater 10, the utilization efficiency of the high-temperature condensed water can be more effectively improved and the waste of the high-temperature condensed water can be avoided.

[0089] Further, in order to more effectively avoid the waste of high-temperature condensate, the specific steps of controlling at least one of the first water heater 8, the second water heater 9 and the third water heater 10 to work according to the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet and the water level of the condensate storage tank 1 are judged in sequence according to the arrangement order. That is, if the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is not greater than 7.5°C and the water level of the condensate storage tank 1 is not greater than 3m, then it is judged whether the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is greater than 7.5°C and whether the water level of the condensate storage tank 1 is less than 3m and greater than 1.7m. If the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is not greater than 7.5°C and the water level of the condensate storage tank 1 is not less than 3m and greater than 1.7m, then it is judged whether the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is greater than 5°C and less than 7.5°C and whether the water level of the condensate storage tank 1 is greater than 1.7m. If the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is not greater than 5°C and less than 7.5°C and the water level of the condensate storage tank 1 is not greater than 1.7m, then determine whether the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is greater than 3°C and less than 5°C and whether the water level of the condensate storage tank 1 is greater than 1.7m. If the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is not greater than 3°C and less than 5°C and the water level of the condensate storage tank 1 is not greater than 1.7m, then determine whether the difference between the preset temperature value and the temperature value of the air-conditioning air supply outlet is greater than 1.5°C and less than 3°C and whether the water level of the condensate storage tank 1 is greater than 1.7m. Finally, the appropriate flow mode of high-temperature condensate in the water heater mechanism is obtained.

[0090] In one embodiment of the water heater circulation application method of high-temperature condensate water, the water heater circulation application method of high-temperature condensate water further includes the following steps:

[0091] The temperature of the condensed water in the water heater outlet manifold 17 is detected by the outlet water temperature detection unit 18 .

[0092] It is determined whether the temperature of the condensed water in the water outlet manifold 17 of the water heater is higher than 60° C. and the water level of the condensed water storage tank 1 is lower than 2.3 m.

[0093] If the temperature of the condensate in the water heater outlet manifold 17 is higher than 60°C and the water level in the condensate storage tank 1 is lower than 2.3m, open the return solenoid valve 24 and close the boiler pipeline solenoid valve 19 to return the condensate flowing out of the water heater outlet manifold 17 to the condensate storage tank 1.

[0094] When the temperature of the condensed water in the water heater outlet manifold 17 is higher than 60°C and the water level in the condensed water storage tank 1 is lower than 2.3m, it indicates that the residual temperature of the condensed water in the water heater outlet manifold 17 is high, and the water level in the condensed water storage tank 1 is low, and the condensed water in the water heater outlet manifold 17 has the value and need to flow back to the condensed water storage tank 1. At this time, the reflux solenoid valve 24 is opened and the boiler pipeline solenoid valve 19 is closed, that is, the condensed water reflux mechanism is connected, so that the condensed water flowing out of the water heater outlet manifold 17 flows back to the condensed water storage tank 1.

[0095] If the temperature of the condensate in the water heater outlet manifold 17 is lower than 60°C and / or the water level in the condensate storage tank 1 is higher than 2.3m, open the boiler pipeline solenoid valve 19 and close the return solenoid valve 24 to direct the condensate flowing out of the water heater outlet manifold 17 to the boiler 22.

[0096] When the temperature of the condensed water in the water heater outlet manifold 17 is lower than 60°C and / or the water level in the condensed water storage tank 1 is higher than 2.3m, it indicates that the residual temperature of the condensed water in the water heater outlet manifold 17 is low, or the amount of water in the condensed water storage tank 1 is sufficient, and the condensed water in the water heater outlet manifold 17 has no value to flow back to the condensed water storage tank 1. However, the condensed water in the water heater outlet manifold 17 still has residual temperature and is softened water, which has a high economic value. At this time, the boiler pipeline solenoid valve 19 is opened and the reflux solenoid valve 24 is closed, that is, the boiler utilization mechanism is connected, so that the condensed water flowing out of the water heater outlet manifold 17 flows to the softened water tank 20 and finally enters the boiler 22.

It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
