Abstract
The utility model provides a cooling tower water temperature control system, includes: the first temperature meter, hygrometer, atmospheric pressure meter, the second temperature meter, controller and cooling tower, the controller respectively with the first temperature meter the hygrometer the atmospheric pressure meter the second temperature meter with the cooling tower is connected, the second temperature meter sets up in the water flow outlet's of cooling tower bottom, the cooling tower is provided with the fan. The beneficial effects of the utility model are that cooling tower water temperature control system's refrigeration efficiency is very high, can not cause the waste of energy.
Description
Technical field
The utility model relates to air conditioner refrigerating field, is specifically related to a kind of cooling column water temperature Controlling System.
Background technology
In existing air-conditioning system, the fan of cooling tower runs cooling water temperature, actual is accelerate air flow, making water coolant accelerate the process of evaporation, evaporative process air absorbs the heat of water coolant, thus reaches the object (certainly except heat trnasfer part) reducing coolant water temperature. But in this process, if external temperature is higher, and our the water coolant leaving water temperature(LWT) of setting is lower, adopts Traditional control strategy will constantly strengthen the travelling speed of blower fan, until maximum frequency runs. And at this moment, if the water temperature of water coolant is when dropping near wet-bulb temperature, no matter blower fan leaves much, water temperature all can not continue to reduce. That is, if we only blow in, the half of machine frequency transformer maximum frequency of operation just can make coolant water temperature reach near wet-bulb temperature, and the energy that additional blower fan load uses just is consumed in vain, and this will cause the huge waste on the energy. The refrigerating efficiency of existing air-conditioning system is very low, causes the waste of energy.
Summary of the invention
Very low for solving the refrigerating efficiency of prior art air-conditioning system, cause the problem such as waste of energy, the utility model proposes a kind of cooling column water temperature Controlling System.
A kind of cooling column water temperature Controlling System that the utility model provides, it is characterised in that, comprising: the first thermometer, wet bulb thermometer, atmospheric pressure meter, the 2nd thermometer, controller and cooling tower; Described controller is connected with described first thermometer, described wet bulb thermometer, described atmospheric pressure meter, described 2nd thermometer and described cooling tower respectively; Described 2nd thermometer is arranged at the bottom of the water export of cooling tower; Described cooling tower is provided with blower fan.
Further, described cooling tower comprises 3 blower fans.
Further, the quantity of described cooling tower is 4 and parallel with one another.
The refrigerating efficiency that the beneficial effects of the utility model are cooling column water temperature Controlling System is very high, can not cause the waste of energy.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model cooling column water temperature Controlling System one implements mode.
Embodiment
Fig. 1 is the structural representation that the utility model cooling column water temperature Controlling System 1 one implements mode. In figure, 1 is cooling column water temperature Controlling System, and 10 is the first thermometer, and 12 is wet bulb thermometer, and 14 is atmospheric pressure meter, and 16 is controller, and 18 is the 2nd thermometer, and 20 is cooling tower, and 22 is blower fan.
Refer to Fig. 1, for the utility model cooling column water temperature Controlling System 1 one implements the structural representation of mode, in the present embodiment, cooling column water temperature Controlling System 1 comprises: the first thermometer 10, wet bulb thermometer 12, atmospheric pressure meter 14, the 2nd thermometer 18, controller 16 and cooling tower 20. Controller 16 is connected with the first thermometer 10, wet bulb thermometer 12, atmospheric pressure meter 14, the 2nd thermometer 18 and cooling tower 20 respectively. 2nd thermometer 18 is arranged at the bottom of the water export of cooling tower 20, for the water temperature measured in cooling tower 20. The temperature of the first thermometer 10 for measuring in the outside air of cooling column water temperature Controlling System 1. The humidity of wet bulb thermometer 12 for measuring in the outside air of cooling column water temperature Controlling System 1. Atmospheric pressure meter 14 is for measuring the outside air pressure of cooling column water temperature Controlling System 1. Controller 16 obtains wet-bulb temperature according to the temperature of air, the humidity of air and air pressure, then compared with the water temperature of cooling tower 20 is added approach sum with wet-bulb temperature, thus control the rotation of blower fan. In the present embodiment, approach is 3-5 degree.
Cooling tower 20 is provided with blower fan 22. In the present embodiment, cooling tower 20 comprises 3 blower fans 22. The quantity of cooling tower 20 is 4 and parallel with one another.
In the present embodiment, cooling tower 24 comprises 3 blower fans 26, and cooling tower group 12 comprises 4 cooling towers 24. Water supply pump group 10 comprises 5 water supply pumps, and wherein, 4 water supply pumps are conventional water supply pump, and 1 water supply pump is water supply pump for subsequent use. 4 conventional water supply pumps and 4 cooling towers 24 connect one to one.
In one embodiment, when the water temperature of cooling tower 20 adds approach less than or equal to wet-bulb temperature, controller 16 thinks the running frequency of now blower fan 22 and water temperature, and it doesn't matter. Even if water temperature does not drop to design temperature, system, by no longer increasing the running frequency of blower fan 22, can not cause the waste of energy. When the water temperature of cooling tower 20 adds approach higher than wet-bulb temperature, the relation that the running frequency of now blower fan 22 and water temperature are inversely proportional to thought by controller 16, the running frequency linear regulation of blower fan 22, heat in water coolant is taken away smoothly by blower fan 22 by air, can not cause the waste of energy.
The concrete enforcement of the utility model cooling column water temperature Controlling System 1, it is possible to relate to use software, but the software the used software that to be all those skilled in the art the most frequently used, and, the not claimed scope of present patent application claim.
Obviously, just due to the cooling column water temperature Controlling System 1 in the utility model enforcement mode, the refrigerating efficiency that the beneficial effects of the utility model are cooling column water temperature Controlling System 1 is very high, can not cause the waste of energy.
The foregoing is only preferred embodiment of the present utility model; it is not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any amendment of being done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
