Described temp detecting controller also has the supply water temperature sensor that is used to detect supply water temperature, and the supply water temperature sensor is arranged at the water main, the quantity that described temperature detection controller is opened blower fan according to the temperature approach control of supply water temperature and each return water temperature.
Described temp detecting controller has the timer of each fan operation time of accumulative total, and according to controlling short blower fan startup earlier running time the running time of this counter accumulative total, starts behind the blower fan of long operational time.
Described blast self-opening air-valve is a louvered air blade valve, and air blade is two groups, and along valve center line symmetric arrays, the rotating shaft at blade two ends is positioned at 1/3rd places, end, and opens the locating part that 85 degree positions, angle are provided with the rotation of restriction air blade at air blade.Described air blade is made by fiberglass.
Each cooling tower shape, structure are identical.
Described cooling tower tower body shape is box-shaped.
Adopt cooling tower of the present utility model, because the feed pipe of each cooling tower and return pipe and be unified into the water main and the return main, when many main frames air-conditioning system has only fractional load, system's hot water can all cool in the cooling tower, can effectively utilize the area of dissipation of cooling tower, thereby reduce blower fan start quantity, reduce energy resource consumption, not reach when requiring to be higher than setting value in cooling tower nature cooling backwater temperature, control fan starting again, can reach good energy-saving effect.Because each cooling tower cross connection, the hot water that enters each cooling tower by each feed pipe from the water main each cooling tower heat radiation of can flowing through, and wherein a certain or the operation of a few typhoon machine can be all cooling tower coolings, thereby improve the cooling effectiveness of cooling tower; Automatically open because of the blast effect during at fan starting from the valve that blows at the wind pressure type of each fan outlet setting; and when blower fan is shut down, under the effect of deadweight, close; can avoid when the part blower fan is worked; the cooling air enters from other fan outlets; directly drain again from the fan outlet of operation; produce string wind, do not have the effect of cooling heat dissipation filler.Wind pressure type adopts louvered air blade valve from the valve that blows in; because every weight is lighter; the unlatching resistance is little; the locating part that is provided with can avoid excessive being difficult to of air blade opening angle to reset; and the air blade rotating shaft is arranged on blade tip 1/3rd places; can make air blade one side heavier, thereby guarantee that when blower fan is shut down air blade recovers closing position under the gravity effect.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Consult Fig. 1, Fig. 2, many main frames air-conditioning system automatic control cooling tower of the present utility model, comprise a plurality of cooling towers 1, heat radiation filler (omitting among the figure) is housed in the cooling tower 1, be provided with cooling blower 2 and feed pipe 3, return pipe 5 at each cooling tower 1, each cooling tower 1 is cross connection each other, and each feed pipe 3 and each return pipe 5 respectively and connect and form water main 4 and return main 6 are provided with blast self-opening air-valve 7 at the air outlet of described cooling blower 2; In this air-conditioning system, also be provided with temp detecting controller, the return water temperature sensor of temp detecting controller is arranged at return main 6, temp detecting controller reaches or the blower fan 2 that is higher than setting value time control system cooling tower is opened at return main 6 return water temperature, and closes at the blower fan 2 that its return water temperature is lower than the time control system of setting value cooling tower.Described temp detecting controller also has the supply water temperature sensor that is used to detect supply water temperature, and the supply water temperature sensor is arranged at the water main, the quantity that described temperature detection controller is opened blower fan according to the temperature approach control of supply water temperature and each return water temperature.Described temp detecting controller has the timer of each fan operation time of accumulative total, and according to controlling short blower fan startup earlier running time the running time of this counter accumulative total, starts behind the blower fan of long operational time.Each cooling tower 1 shape, structure are identical, become modularized design, can exchange between the cooling tower tower body 1, increase versatility.Described cooling tower tower body shape is box-shaped, and it is simple in structure, be convenient to make.
Shown in Fig. 3-6, described blast self-opening air-valve is a louvered air blade valve, air blade 8 is two groups, along valve center line symmetric arrays, the rotating shaft 9 at blade 8 two ends is positioned at 1/3rd places, end, and opens locating part 9 (not shown)s that 85 degree positions, angle are provided with 8 rotations of restriction air blade at air blade.Described air blade can be made by fiberglass, and its weight is lighter, and material cost is also lower.
Its control procedure is as follows: such as setting return water temperature is 33 ℃, is lower than 33 ℃ of each blower fans at return water temperature and does not all start, and hot water only depends on the cooling tower self-radiating to cool off; When return water temperature reaches 33 ℃, control wherein moves the shortest fan starting of cumulative time, when supply water temperature reaches 35 ℃, and the fan starting of operation cumulative time second weak point, the rest may be inferred ..., the supply water temperature quantity that starts blower fan that raises again increases successively until reaching at full capacity.When cooling load descended, blower fan then stopped successively, and when return water temperature was lower than 33 ℃, all blower fans stopped.
