The invention provides a cooling method, which is a method for cooling based on the cooling tower module and comprises the following steps:
s1, acquiring the temperature of outdoor air wet bulb and the air conditioning temperature and humidity requirements in a subway station;
and S2, switching the cooling tower module to working modes in different seasons according to the outdoor air wet bulb temperature obtained in the S1 and the air conditioning temperature and humidity requirements in the subway station.
The novel cooling tower is placed in an underground station according to the direction of tunnel wind, and the following three working modes can be obtained according to the temperature of outdoor air wet bulb and the air conditioning temperature and humidity requirement in the subway station:
specifically, the cooling tower module has three operating modes, namely a summer operating mode, a winter operating mode and a transition season operating mode.
1) And in the summer working mode, when the cooling tower module operates in the summer working mode, the chilled water is prepared by the water chilling unit, and the cooling water is prepared by the novel cooling tower. The positive pressure fan 1 is started, the negative pressure fan 12 is started, the first electric air valve 4 in the control assembly is opened, and the second electric air valve 3 is closed; the indirect evaporative cooling assembly stops running, and the indirect evaporative cooling circulating water pump 5 is closed; outdoor fresh air is sucked by the positive pressure fan 1 and then is subjected to primary filtration through the primary filter 2, the filtered fresh air enters the bypass air inlet duct 15 through the first electric air valve 4 and then enters the filler 8 in the cooling tower body, and is subjected to heat exchange with cooling water automatically sprayed to the surface of the filler 8 by the cooling tower water distributor 9, so that the purpose of reducing the temperature of the cooling water is achieved, saturated hot and humid air after absorbing heat, namely the saturated hot and humid air after heat exchange is finished, enters the exhaust duct 14 through the filtering interlayer 13, is exhausted into a subway tunnel through the negative pressure fan 12, and circulation is finished. The cooling tower is used as a conventional cooling tower of a water chilling unit
2) And in the winter working mode, when the cooling tower module operates in the winter working mode, the novel cooling tower is used for preparing low-temperature cooling water and exchanging heat with tail-end cooling water through the plate heat exchanger. The positive pressure fan 1 is required to be opened, the negative pressure fan 12 is required to be opened, the first electric air valve 4 in the control assembly is closed, and the second electric air valve 3 is opened; the indirect evaporation cooling assembly starts to operate, the indirect evaporation cooling circulating water pump 5 is opened, outdoor fresh air is sucked by the positive pressure fan 1 and then passes through the primary filter 2 for primary filtration, because the first electric air valve 4 is closed, the precooled fresh air can only pass through the indirect evaporation cooler 6 and then is further subjected to equal-humidity cooling, enters the cooling tower filler 8 and is subjected to heat exchange with cooling water automatically sprayed to the surface of the filler 8 by the cooling tower water distributor 9, the temperature of the cooling water is reduced, saturated hot and wet air after absorbing heat is mixed with secondary air entering the indirect evaporation cooling assembly from the second electric air valve 3 through the filtering interlayer to the exhaust passage 14 and then is discharged into a subway tunnel by the negative pressure fan 12, and circulation is completed.
The flow path for the secondary air is as follows: meanwhile, outdoor fresh air enters from an air inlet below the indirect evaporative cooler 6, exchanges heat with spray water of the indirect evaporative cold water distributor 7 in a wet channel on the outer wall of the tube, cools primary air on the inner wall of the indirect evaporative cooler, passes through the second electric air valve 3 on the upper side, is mixed with the primary air passing through the filtering interlayer 13, and is pumped out by the negative pressure fan 12, and circulation is completed. When the temperature of the prepared cooling water meets the temperature requirement of the chilled water at the tail end of the subway station, the cooling water is cooled through the plate heat exchanger, and the natural cooling of the cold water of the subway station is realized by utilizing the cooling tower. At the moment, in order to reduce the energy consumption of the air conditioner, the water chilling unit can be closed.
3) A transition season mode of operation when the cooling tower module is operating in the transition season mode of operation; when the temperature of the outdoor air wet bulb is lower than the indoor return air temperature of the subway station and higher than the temperature of the wet bulb which is completely and naturally cooled by the cooling tower, and the cooling water temperature of the cooling tower cannot independently bear the cooling load at the tail end of the air conditioner of the subway station, the water chilling unit is started to supplement the cooling capacity.
A first electric air valve 4 in the control assembly is opened, and a second electric air valve 3 in the control assembly is opened; outdoor fresh air is sucked by the positive pressure fan 1, is primarily filtered through the primary filter 2, then enters the bypass air inlet duct 15 through the first electric air valve 4 in part, enters the indirect evaporative cooling assembly for equal-humidity cooling in the rest part, converges and enters the cooling tower body, completes heat exchange, enters the exhaust duct 14 through the filtering interlayer 13, is mixed with secondary air entering from the second electric air valve 3 in the indirect evaporative cooling assembly, and is discharged into a subway tunnel through the negative pressure fan 12, and the circulation is completed.
When the cooling tower module operates in a transition season working mode, the method further comprises an air quantity adjusting step, wherein the frequency of the positive pressure fan 1 and/or the negative pressure fan 12 and the opening degree of the second electric air valve 3 are adjusted according to the outdoor wet bulb temperature so as to adjust the temperature of the air wet bulb entering the cooling tower body in real time, and therefore the temperature of the prepared cooling water is adjusted.
Because the outdoor temperature difference is great day and night in the transition season, the air quantity passing through the indirect evaporative cooler 6 is controlled by adjusting the frequency of the positive pressure fan 1 and the negative pressure fan 12 and the opening degree of the second electric air valve 3 according to the outdoor wet bulb temperature change, the temperature of the air wet bulb entering the cooling tower filler 8 is adjusted in real time, and the temperature of the prepared cooling water is adjusted in time, so that the system integrally realizes the optimal energy efficiency operation. At the moment, the water chilling unit and the cooling tower simultaneously run at low load, so that the real-time optimal energy-saving effect is achieved.
Specifically, when the outdoor temperature is high in the daytime, the operating frequency of the negative pressure fan 12 is increased, and the opening degree of the second electric air valve 3 is increased. Because the air quantity drawn by the negative pressure fan 12 is equal to the sum of the air quantity drawn by the positive pressure fan 1 and the air quantity drawn by the bottom of the evaporative cooling equipment, when the drawn air quantity is increased, the bottom air quantity is increased, and meanwhile, the air quantity of the evaporative cooling equipment is increased, the evaporative cooling heat exchange efficiency is improved, the air temperature introduced into the filler is further reduced, and the cooling water approaching the outdoor temperature is prepared.
When the outdoor wet bulb temperature is lower at night, the running frequency of the negative pressure fan 12 is reduced, and the opening degree of the second electric air valve 3 is reduced. When the air quantity is reduced, the bottom suction air quantity is reduced, meanwhile, the air quantity of the evaporation cooling equipment is reduced, the heat exchange efficiency of evaporation cooling is reduced, the air temperature of the introduced filler is improved, and cooling water with proper temperature is prepared, so that the stable and efficient work of an air conditioning system is ensured.
