Taking the working condition of operating in autumn as an example, the second air inlet window 5 is gradually opened along with the gradual reduction of the ambient temperature until reaching the water cut-off temperature, at the moment, the second air inlet window 5 is completely opened, the spraying device 8 is closed, and the working condition is transited to the working condition in winter. In this transition process, the heat exchange capacity of the air-cooled heat exchange member 2 is gradually improved. Compared with the composite cooler in the prior art, the cold fresh air is introduced into the lower part of the air cooling heat exchange part 2 step by step and is mixed with the saturated humid hot air at the outlet of the evaporative heat exchange part 9, and the ventilation temperature of the mixed air cooling heat exchange part 2 is lower than the temperature of the high humid hot air at the outlet of the evaporative heat exchange part 9. Therefore, the air-cooled heat exchange member 2 takes more heat load than the prior art multiple cooler. Accordingly, the heat load to be taken away by the evaporative heat exchange section 9 is reduced. Meanwhile, as the second air inlet window 5 is gradually opened, the air quantity passing through the evaporative heat exchange part 9 is gradually reduced, the opening degree of the second air inlet window 5 can be intelligently adjusted through the control device according to the change of the ambient temperature, the relative humidity and the like, and the evaporation quantity of the spray water of the evaporative heat exchange part 9 is always in a dynamic minimum value on the premise of ensuring the temperature of the medium outlet in the pipe to be unchanged, so that the aim of saving water for one time is fulfilled. The outlet of the evaporative heat exchange part 9 is provided with a first water receiver 7, and the first water receiver 7 is used for separating water from water drops carried in saturated humid hot air at the outlet of the evaporative heat exchange part 9 and recovering part of water resources. Part of fresh cold air is introduced through the second air inlet window 5, the fresh cold air is mixed with the damp and hot air at the outlet of the evaporative heat exchange component 9 in the fresh air mixing chamber 6, the temperature of the mixed air is reduced, part of condensed water is separated from the damp and hot air, and then the steam and water are separated through the second water collector 4, so that the purpose of secondary water saving is achieved. Correspondingly, the second air inlet window 5 is gradually opened, and the resistance of the whole machine equipment is gradually reduced. Through the intelligent control of the control device, the water consumption and the energy consumption are always in the dynamic minimum value on the premise of ensuring the performance of the whole machine, thereby achieving the purposes of saving water and energy to the maximum extent.
Taking the operation condition of water cut-off in winter as an example, the control device controls the spray device 8 to be closed through the circulating pump, the second air inlet window 5 is completely opened, and fresh air mainly enters the device through the second air inlet window 5. The environment temperature is low in winter, the air cooling heat exchange part 2 is used as a main heat exchange part to directly exchange heat with air, and the evaporation type heat exchange part 9 is used as a secondary heat exchange part to assist in operation. Because the new trend mainly gets into equipment through second air inlet window 5, complete machine equipment windage drops to the minimum, and the amount of wind is in the maximum. Compared with a composite cooler in the prior art, the air cooler has the advantages that the air quantity is larger under the operation working condition in winter, and the ventilation temperature of the air cooling heat exchange part 2 is lower, so that higher water stop temperature can be achieved.
The dynamic and intelligent water and energy saving adjusting process of the present invention will now be further described with reference to fig. 2.
Taking autumn operation condition as an example, setting the ambient temperature t1Relative humidity RH, medium inlet and outlet temperature T1、T2When monitoring points are met, the control device carries out logic calculation according to monitoring data, when monitoring parameters are smaller than the design value of the equipment, the control device gradually opens the second air inlet window 5 through the connecting rod mechanism 10 and the transmission mechanism 11, at the moment, the resistance of the whole equipment is reduced, fresh air Q is introduced from the second air inlet window 5, and at the moment, the air quantity Q of the evaporative heat exchange part 9 is1The head-on wind speed of the evaporative heat exchange part 9 is reduced, the heat load taken away is reduced, and the evaporation amount is reduced along with the reduction; the damp and hot air at the outlet of the evaporative heat exchange component 9 is mixed with the fresh air Q introduced by the second air inlet window 5, and the mixed air temperature is the ventilation temperature t of the air cooling heat exchange component 23，t3＜t2Meanwhile, the head-on wind speed of the air cooling heat exchange component 2 is increased, and the heat load is increased; monitoring the medium outlet temperature T2When T is2When the air inlet window exceeds the set range, the opening degree of the second air inlet window 5 is further adjusted through the feedback signal. In this regulation process, the medium outlet temperature T is satisfied2And the like on the premise of parameter requirements. The resistance of the whole machine equipment and the evaporation capacity of the spraying water of the evaporative heat exchange part 9 are always in the dynamic minimum value. When the ambient temperature t1And when the monitoring values of external factors such as relative humidity RH are gradually reduced, the opening degree of the second air inlet window 5 is further increased through the actuating mechanism, and the adjusting process is repeated until the second air inlet window 5 is completely opened, at the moment, the resistance of the whole machine equipment is minimum, the evaporation capacity of the spray water of the evaporative heat exchange part 9 is minimum, and the operation condition is transited to the autumn operation condition. And when the monitored parameters meet the design water cut-off requirement of the equipment, closing the spraying device 8 and transitioning to the winter operation working condition. Simultaneously, because second air inlet window 5 opens completely, reduced complete machine equipment resistance, the amount of wind increases thereupon, compares with the compound cooler among the prior art, and the temperature of cutting off the water is higher.
And the process of adjusting the operating condition in spring is vice versa.
