Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1, a kind of air draft cold reclaiming type cooling tower, cooling tower 1 is hollow columnar structures,
The cooling tower of the present embodiment is cross flow cooling tower, air intake from tower body lower end sidepiece from horizontal cross
Direction enter in tower body.Outside cooling tower 1 tower body, lower end is provided with sky the most in communication
Adjust air draft recovery tube 4 and fresh wind tube 3.Filler 2 it is provided with in cooling tower 1.Filler 2 is used for
Strengthen heat transfer efficiency, increase the area of gas-to-liquid contact.Filler 2 is positioned at cooling tower 1 air intake with cold
But between the axis of tower 1.
As it is shown in figure 1, air conditioning air exhaust recovery tube 4 one end connection cooling tower 1 tower of the present embodiment
Interior space, the other end is accepted the air draft in air-conditioning place, air conditioning air exhaust recovery tube 4 is provided with control
The air draft switching valve 7 of air conditioning air exhaust recovery tube 4 processed folding, fresh wind tube 3 one end connection cooling tower
Space in 1 tower, the other end is accepted outdoor new wind, fresh wind tube 3 is provided with control fresh wind tube 3
The new wind switching valve 6 of folding.
Air conditioning air exhaust recovery tube 4 and the fresh wind tube 3 of the present embodiment have multipair respectively, every pair of air-conditioning
Air draft recovery tube 4 is respectively arranged in the opposite end of cooling tower 1 radial direction, every pair of fresh wind tube
3 are respectively arranged in the opposite end of cooling tower 1 radial direction.Exhaust duct 4 and fresh wind tube 3 edge
Cooling tower 1 axis direction is arranged in the side of cooling tower 1, position in the way of upper and lower Juxtaposition and Superimposition
It is in same vertical plane in the exhaust duct 4 of cooling tower 1 homonymy and the axis of fresh wind tube 3.
When air conditioning air exhaust recovery tube 4 needs to use, the gas in air conditioning air exhaust recovery tube 4
Temperature is less than the gas temperature in fresh wind tube 3, and the low gas density of temperature is big, arranges from air-conditioning
The port of export of wind recovery tube 4 out after first sink.By air conditioning air exhaust recovery tube 4 and new wind
Pipe 3 is arranged to the mode of upper and lower superposition, the newest wind and and air draft sufficiently mix, favorably
In follow-up and in cooling tower 1 cooling liquid heat exchange.
The air conditioning air exhaust recovery tube 4 of both sides and fresh wind tube 3 arranged relative, strengthen cooling tower 1
The turbulent extent of interior air-flow, makes the gas mixing in cooling tower 1 more uniform, strengthens heat friendship
The efficiency changed.
In order to strengthen the ventilation velocity in air conditioning air exhaust recovery tube 4, the present embodiment is at air conditioning air exhaust
Being provided with blower fan 5 in recovery tube 4, blower fan 5 is positioned at air draft switching valve 7 along air current flow direction
Upstream end.The power of the air flowing in fresh wind tube 3 is provided by the blower fan in cooling tower 1.
The fresh wind tube 3 of the present embodiment and the port of export of air conditioning air exhaust recovery tube 4 are provided with sensing
Device is used for detecting the enthalpy of new wind and air draft, these sensors and control device data cube computation, control
Device processed controls new wind and the air output of air draft according to the measured value of sensor, reaches optimal with this
Air inlet effect.Control device to be connected with new wind switching valve 6, air draft switching valve 7 and blower fan 5.
During use, the cooling tower of the present embodiment has three kinds of operational modes.
The first: as in figure 2 it is shown, all-fresh air operating mode, when outdoor air enthalpy is arranged less than air-conditioning
During wind, closing air draft switching valve 7, open new wind switching valve 6, the air intake of cooling tower 1 all comes
From outdoor fresh air, the efficiency of this kind of operating mode cooling tower is the most not compared with conventional chilling tower
Become.
The second: as it is shown on figure 3, air-conditioning full air draft operating mode, when outdoor air enthalpy is higher than sky
When adjusting air draft, close new wind switching valve 6, open air draft switching valve 7 and blower fan 5, cooling tower
The air intake of 1 is all from the air draft of central air conditioner system, and under this kind of operating mode, efficiency of cooling tower is higher,
And cooling water return water temperature reduces, handpiece Water Chilling Units COP improves therewith.
The third: as shown in Figure 4, the mixed wind operating mode of new wind, air conditioning air exhaust combination, this operating mode
Lower basis is installed on the height of the enthalpy sensor mensuration enthalpy of each entrance, by control is
Tracking saves each line changeover valve aperture, to determine best air intake enthalpy.This not only makes this
Cooling tower 1 is in hgher efficiency, also makes cooling tower 1 run and has more operability.
Of the present utility model ultimate principle, principal character and this practicality are more than shown and described new
The advantage of type.Skilled person will appreciate that of the industry, this utility model is not by above-described embodiment
Restriction, principle of the present utility model is simply described described in above-described embodiment and description,
On the premise of without departing from this utility model spirit and scope, this utility model also has various change
Change and improve, in the range of these changes and improvements both fall within claimed this utility model.This
