As shown in fig. 2, the present disclosure also provides a comprehensive application method of high-temperature condensed water based on the comprehensive application device of high-temperature condensed water of the present disclosure, which includes the following steps:
whether the water level in the condensed water storage tank 1 is larger than a preset output water level or not and whether the water level in the condensed water storage tank 1 is larger than a boiler utilization water level or not are judged, and the boiler utilization water level is higher than the preset output water level. The preset output water and the boiler utilization water level can be flexibly set according to actual requirements. The water level in the condensed water storage tank 1 reaches the preset output water level first and then reaches the boiler utilization water level.
When the water level in the condensed water storage tank 1 is not more than the preset output water level, it indicates that the amount of water in the condensed water storage tank 1 is insufficient and there is no condensed water output condition. The condensate return valve 19, the water heating solenoid main valve 7 and the condensate high-pressure valve 23 are all closed at this time to prevent the condensate in the condensate storage tank 1 from entering the application step.
If the water level in the condensed water storage tank 1 is higher than the preset output water level and the water level in the condensed water storage tank 1 is higher than the boiler utilization water level, the condensed water direct-return valve 19 is opened and the condensed water high-pressure valve 23 and the water heating electromagnetic main valve 7 are closed, so that the condensed water in the condensed water storage tank 1 flows through the condensed water pressurizing pump 6, the condensed water direct-return valve 19, the softened water tank 20 and the boiler water inlet pump 21 from the water outlet in sequence and enters the boiler 22.
When the water level in the condensate storage tank 1 is greater than the preset output water level and the water level in the condensate storage tank 1 is greater than the boiler utilization water level, it indicates that the condensate in the condensate storage tank 1 is close to the maximum reserve level thereof. To avoid the condensate overflow waste, the condensate in the condensate storage tank 1 may enter the boiler 22. That is, the condensate return valve 19 is opened and the condensate high-pressure valve 23 and the water heating solenoid main valve 7 are closed, so that the condensate in the condensate storage tank 1 flows through the condensate pressurizing pump 6, the condensate return valve 19, the softened water tank 20 and the boiler water inlet pump 21 in sequence from the water outlet and finally enters the boiler 22.
If the water level in the condensed water storage tank 1 is higher than the preset output water level and the water level in the condensed water storage tank 1 is lower than the boiler utilization water level, whether the temperature and humidity value of an air supply port of the air conditioner is lower than the preset temperature and humidity value and whether the temperature in the condensed water storage tank 1 is higher than the output temperature are judged. The output temperature may be, for example, 50 ℃.
When the water level in the condensate storage tank 1 is higher than the preset output water level and the water level in the condensate storage tank 1 is lower than the boiler utilization water level, it indicates that the condensate in the condensate storage tank 1 is not enough to meet the requirement of the boiler 22, but the condensate in the condensate storage tank 1 is available. At this time, whether the temperature and humidity of the air flow in the air-conditioning air box need to be adjusted or not can be judged.
When the temperature and humidity value of the air supply port of the air conditioner is not less than the preset temperature and humidity value and the temperature in the condensed water storage tank 1 is lower than the output temperature, the comprehensive application device of the high-temperature condensed water does not meet the condition of supplying and heating air to the air supply port of the air conditioner, and the condensed water pressure pump 6 can be closed.
If the temperature and humidity value of the air supply port of the air conditioner is smaller than the preset temperature and humidity value and the temperature in the condensed water storage tank 1 is higher than the output temperature, it is shown that the comprehensive application device of the high-temperature condensed water meets the condition of supplying and heating air to the air conditioner port, the condensed water pressure pump 6 is opened, the condensed water direct return valve 19 is closed, and the condensed water high-pressure valve 23 and the water heating electromagnetic main valve 7 are opened, so that the condensed water in the condensed water storage tank 1 flows through the condensed water pressure pump 6 from the water outlet 102 and then respectively enters the water heater mechanism and the air conditioner bellows spraying mechanism, and the air supply heating is performed on the air conditioner by the water heater mechanism, and the air flow in the air conditioner bellows is subjected to hot.
When the temperature and humidity value of the air supply air inlet of the air conditioner is smaller than the preset temperature and humidity value and the temperature in the condensed water storage tank 1 is higher than the output temperature, it is indicated that the temperature and the humidity of the air flow in the air conditioner air box need to be adjusted, and the temperature of the condensed water in the condensed water storage tank 1 can meet the requirements of the air conditioner. At this time, the condensate return valve 19 is closed and the condensate high-pressure valve 23 and the water heating solenoid main valve 7 are opened, so that the condensate in the condensate storage tank 1 can enter the water heater mechanism and the air box spraying mechanism of the air conditioner and be utilized.
The condensed water entering the spraying mechanism of the air-conditioning air box can flow through the condensed water high-pressure valve 23, the condensed water high-pressure filter 24 and the hot mist humidifier 25 in sequence, so that the air flow in the air-conditioning air box is subjected to hot mist humidification and heating.
For part of the condensed water entering the water heater mechanism, in order to improve the utilization efficiency, whether the temperature of the air flow in the air conditioning box needs to be increased and whether the water level in the condensed water storage tank 1 can meet the temperature increase requirement can be further judged. Therefore, when the temperature and humidity value of the air supply outlet of the air conditioner is smaller than the preset temperature and humidity value and the temperature in the condensed water storage tank 1 is higher than the output temperature, the difference value between the preset temperature value and the temperature value of the air supply outlet of the air conditioner is calculated, the water level of the condensed water storage tank 1 is obtained, and the water heating electromagnetic main valve 7 is controlled to be opened and closed according to the difference value between the preset temperature value and the temperature value of the air supply outlet of the air conditioner and the water level of the condensed water storage.
Specifically, the opening and closing of the water heating electromagnetic main valve is controlled according to the difference value between the preset temperature value and the air supply air inlet temperature value of the air conditioner and the water level of the condensed water storage tank 1 as follows:
and if the difference value between the preset temperature value and the temperature value of the air supply air inlet of the air conditioner is less than 1.5 ℃ and/or the water level of the condensed water storage tank 1 is less than 1.6m, closing the water heating electromagnetic main valve 7.
When the difference value between the preset temperature value and the temperature value of the air supply opening of the air conditioner is less than 1.5 ℃ and/or the water level of the condensed water storage tank 1 is less than 1.6m, the fact that the air flow in the air conditioner box does not need to be heated or the water level of the condensed water storage tank 1 is low is indicated. At this time, the water heating solenoid main valve 7 is closed, and the condensed water is prohibited from entering the water heater mechanism.
If the difference value between the preset temperature value and the air supply air inlet temperature value of the air conditioner is larger than 1.5 ℃ and the water level of the condensed water storage tank 1 is larger than 1.6m, the water heating electromagnetic master 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 work according to the difference value between the preset temperature value and the air supply air inlet temperature value of the air conditioner and the water level of the condensed water storage tank 1.
When the difference value between the preset temperature value and the temperature value of the air supply opening of the air conditioner is larger than 1.5 ℃ and the water level of the condensed water storage tank 1 is larger than 1.6m, the fact that the temperature of air in the air conditioner box needs to be increased and the water amount in the condensed water storage tank 1 has output conditions is indicated, the water heating electromagnetic main valve 7 can be opened at the moment, water in the condensed water storage tank 1 can flow to each water heater, and the temperature of the air supply opening of the air conditioner is adjusted through supplying air and heating for the air conditioner opening. The working states of the first water heater 8, the second water heater 9 and the third water heater 10 in the disclosure can be flexibly selected according to actual needs.
In one embodiment of the method for comprehensively applying the high-temperature condensed water, 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 a difference between a preset temperature value and an air supply outlet temperature value of the air conditioner and a water level of the condensed water storage tank 1 as follows:
and if the difference value between the preset temperature value and the temperature value of the air supply air inlet of the air conditioner is more than 7.5 ℃ and the water level of the condensed water storage tank 1 is more than 3m, closing the fifth water heating electromagnetic valve 15 and the sixth water heating electromagnetic valve 16.
When the difference value between the preset temperature value and the temperature value of the air supply opening of the air conditioner is larger than 7.5 ℃ and the water level of the condensed water storage tank 1 is larger than 3m, the temperature increasing requirement of the air flow in the air conditioner box is large and the water amount in the condensed water storage tank 1 is sufficient. In order to enable the high-temperature condensed water to rapidly increase the air supply temperature of the air conditioner, the fifth water heating electromagnetic valve 15 and the sixth water heating electromagnetic valve 16 are closed, the high-temperature condensed water sequentially passes through the water outlet 102, the condensed water pressure pump 6 and the water heating electromagnetic master valve 7 and respectively enters the first water heater 8, the second water heater 9 and the third water heater 10, and the air supply of the air conditioner is heated through the first water heater 8, the second water heater 9 and the third water heater 10.

And if the difference value between the preset temperature value and the temperature value of the air supply air inlet of the air conditioner is more than 7.5 ℃ and the water level of the condensed water storage tank 1 is less than 3m and more than 1.7m, closing the third water heating electromagnetic valve 13, the fourth water heating electromagnetic valve 14 and the fifth water heating electromagnetic valve 15.
When the difference value between the preset temperature value and the temperature value of the air supply opening of the air conditioner is larger than 7.5 ℃ and the water level of the condensed water storage tank 1 is smaller than 3m and larger than 1.7m, the fact that the temperature of the air supply opening of the air conditioner needs to be increased is shown to be large. In order to make full use of the high-temperature condensed water to quickly raise the air supply temperature of the air conditioner, the third water heating electromagnetic valve 13, the fourth water heating electromagnetic valve 14 and the fifth water heating electromagnetic valve 15 are closed, and the high-temperature condensed water sequentially passes through the water outlet 102, the condensed water pressure pump 6 and the water heating electromagnetic main valve 7 and respectively enters the first water heater 8 and the second water heater 9. The high-temperature condensed water entering the first water heater 8 heats the air supplied by the air conditioner, passes through the first water heating electromagnetic valve 11, and then is converged into the water heater water outlet collecting pipe 17 to leave the water heater mechanism. The high-temperature condensed water entering the second water heater 9 heats the air supply of the air conditioner, then enters the third water heater 10 through the sixth water heater electromagnetic valve 16 to heat the air supply of the air conditioner, and the water flowing out of the third water heater 10 converges to the water heater water outlet collecting pipe 17 and leaves the water heater mechanism.
And if the difference value between the preset temperature value and the temperature value of the air supply air inlet of the air conditioner is more than 5 ℃ and less than 7.5 ℃ and the water level of the condensed water storage tank 1 is more than 1.7m, closing the first water heating electromagnetic valve 11, the second water heating electromagnetic valve 12, the third water heating electromagnetic valve 13 and the fourth water heating electromagnetic valve 14.
When the difference value between the preset temperature value and the temperature value of the air supply air inlet of the air conditioner is more than 5 ℃ and less than 7.5 ℃ and the water level of the condensed water storage tank 1 is more than 1.7m, the temperature of the air supply air inlet of the air conditioner needs to be raised not too much. In order to fully utilize the high-temperature condensed water to raise the air supply temperature of the air conditioner, the first water heating electromagnetic valve 11, the second water heating electromagnetic valve 12, the third water heating electromagnetic valve 13 and the fourth water heating electromagnetic valve 14 are closed, the high-temperature condensed water sequentially passes through the water outlet 102, the condensed water pressure pump 6 and the water heating electromagnetic master valve 7, enters the first water heater 8 to heat the air supply of the air conditioner, leaves the first water heater 8, and sequentially enters the second water heater 9 and the third water heater 10 to heat the air supply of the air conditioner. The water flowing from the third water heater 10 flows to the water heater outlet manifold 17 and leaves the water heater mechanism.
And if the difference value between the preset temperature value and the temperature value of the air supply air inlet of the air conditioner is more than 3 ℃ and less than 5 ℃ and the water level of the condensed water storage tank 1 is more than 1.7m, closing the first water heating electromagnetic valve 11, the third water heating electromagnetic valve 13, the fourth water heating electromagnetic valve 14 and the fifth water heating electromagnetic valve 15.
When the difference value between the preset temperature value and the temperature value of the air supply opening of the air conditioner is larger than 3 ℃ and smaller than 5 ℃ and the water level of the condensed water storage tank 1 is larger than 1.7m, the temperature of the air supply opening of the air conditioner needs not to be increased greatly. In order to fully utilize the high-temperature condensed water to raise the air supply temperature of the air conditioner, the first water heating electromagnetic valve 11, the third water heating electromagnetic valve 13, the fourth water heating electromagnetic valve 14 and the fifth water heating electromagnetic valve 15 are closed, the high-temperature condensed water sequentially passes through the water outlet 102, the condensed water pressure pump 6 and the water heating electromagnetic main valve 7, enters the second water heater 9 to heat the air supply of the air conditioner, and then enters the third water heater 10 to heat the air supply of the air conditioner. The water flowing from the third water heater 10 flows to the water heater outlet manifold 17 and leaves the water heater mechanism.
And if the difference value between the preset temperature value and the temperature value of the air supply air inlet of the air conditioner is more than 1.5 ℃ and less than 3 ℃ and the water level of the condensed water storage tank 1 is more than 1.7m, closing the second water heating electromagnetic valve 12, the third water heating electromagnetic valve 13, the fourth water heating electromagnetic valve 14, the fifth water heating electromagnetic valve 15 and the sixth water heating electromagnetic valve 16.
And when the difference value between the preset temperature value and the temperature value of the air supply outlet of the air conditioner is more than 1.5 ℃ and less than 3 ℃ and the water level of the condensed water storage tank 1 is more than 1.7m, the temperature of the air supply outlet of the air conditioner needs to be raised slightly. In order to improve the air supply temperature of the air conditioner, the second water heating electromagnetic valve 12, the third water heating electromagnetic valve 13, the fourth water heating electromagnetic valve 14, the fifth water heating electromagnetic valve 15 and the sixth water heating electromagnetic valve 16 are closed, high-temperature condensed water sequentially passes through the water outlet 102, the condensed water pressure pump 6 and the water heating electromagnetic main valve 7, enters the first water heater 8 and heats the air supply of the air conditioner, and water flowing out of the first water heater 8 flows to the water heater water outlet collecting pipe 17 and leaves the water heater mechanism.
By this method of controlling the operations of the first, second, and third water heaters 8, 9, and 10, it is possible to more effectively improve the utilization efficiency of the high-temperature condensed water and to avoid the waste of the high-temperature condensed water.
Further, in order to more effectively avoid the waste of the high-temperature condensed water, 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 value between the preset temperature value and the air supply outlet temperature value of the air conditioner and the water level of the condensed water storage tank 1 are sequentially judged according to the arrangement sequence. That is, if the difference between the preset temperature value and the air supply outlet temperature value of the air conditioner is not greater than 7.5 ℃ and the water level of the condensed water storage tank 1 is not greater than 3m, it is determined whether the difference between the preset temperature value and the air supply outlet temperature value of the air conditioner is greater than 7.5 ℃ and the water level of the condensed water storage tank 1 is less than 3m and greater than 1.7 m. And if the difference value between the preset temperature value and the air supply air inlet temperature value of the air conditioner is not more than 7.5 ℃ and the water level of the condensed water storage tank 1 is not less than 3m and is more than 1.7m, judging whether the difference value between the preset temperature value and the air supply air inlet temperature value of the air conditioner is more than 5 ℃ and less than 7.5 ℃ and the water level of the condensed water storage tank 1 is more than 1.7 m. And if the difference value between the preset temperature value and the temperature value of the air supply opening of the air conditioner is not more than 5 ℃ and less than 7.5 ℃ and the water level of the condensed water storage tank 1 is not more than 1.7m, judging whether the difference value between the preset temperature value and the temperature value of the air supply opening of the air conditioner is more than 3 ℃ and less than 5 ℃ and the water level of the condensed water storage tank 1 is more than 1.7 m. And if the difference value between the preset temperature value and the air supply air inlet temperature value of the air conditioner is not more than 3 ℃ and less than 5 ℃ and the water level of the condensed water storage tank 1 is not more than 1.7m, judging whether the difference value between the preset temperature value and the air supply air inlet temperature value of the air conditioner is more than 1.5 ℃ and less than 3 ℃ and the water level of the condensed water storage tank 1 is more than 1.7 m. Finally, the proper flowing mode of the high-temperature condensed water in the water heater mechanism is obtained.
In one embodiment of the method for integrated application of high temperature condensate, the method for integrated application of high temperature condensate further comprises the steps of:
the temperature of the condensed water in the outlet manifold 17 of the water heater is detected by the outlet water temperature detection unit 18.
And judging whether the temperature of the condensed water in the water outlet collecting pipe 17 of the water heater is higher than 60 ℃ or not and the water level of the condensed water storage tank 1 is lower than 2.3m or not.
If the temperature of the condensate in the outlet manifold 17 of the water heater is higher than 60 ℃ and the water level in the condensate storage tank 1 is lower than 2.3m, the return solenoid valve 27 is opened and the boiler line solenoid valve 26 is closed to return the condensate flowing out of the outlet manifold 17 of the water heater to the condensate storage tank 1.
When the temperature of the condensed water in the outlet manifold 17 of the water heater is higher than 60 ℃ and the water level of the condensed water storage tank 1 is lower than 2.3m, it indicates that the residual temperature of the condensed water in the outlet manifold 17 of the water heater is higher, and the water level in the condensed water storage tank 1 is lower, and the condensed water in the outlet manifold 17 of the water heater has the value and need to flow back to the condensed water storage tank 1. At this time, the return solenoid valve 27 is opened and the boiler line solenoid valve 26 is closed, so that the condensate flowing out of the outlet manifold 17 of the water heater is returned to the condensate storage tank 1.
If the temperature of the condensate in the outlet manifold 17 of the water heater is below 60 c and/or the water level in the condensate storage tank 1 is above 2.3m, the boiler line solenoid valve 26 is opened and the return solenoid valve 27 is closed to direct the condensate flowing out of the outlet manifold 17 of the water heater to the demineralized water tank 20. The condensed water entering the softened water tank 20 may eventually enter the boiler 22.
When the temperature of the condensed water in the outlet manifold 17 of the water heater is lower than 60 ℃ and/or the water level of the condensed water storage tank 1 is higher than 2.3m, it indicates that the residual temperature of the condensed water in the outlet manifold 17 of the water heater is low, or the amount of the condensed water in the condensed water storage tank 1 is sufficient, and the condensed water in the outlet manifold 17 of the water heater has no value of flowing back to the condensed water storage tank 1. However, the condensed water in the water collecting pipe 17 of the water heater still has residual temperature and is softened water, so that the water heater has higher economic value. At this point, the boiler line solenoid valve 26 is opened and the return solenoid valve 27 is closed so that the condensate flowing from the water heater outlet manifold 17 flows to the demineralized water tank 20 and finally into the boiler 22.
