Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a cooling water tower, and more particularly to a water outlet temperature control technique for a cooling water tower. [Prior Art] [0002] Please refer to "Figure 1", which is the conventional cooling tower 1, ice water host 2 and external air conditioning box (MA103 installation architecture diagram, cooling tower 1 main $ is to provide cooling water supply The condenser 4 of the ice water main unit 2 is used to cool the refrigerant which is compressed by the compressor 5 to generate a high-temperature gaseous state. After the condensation, the liquid A medium passes through the expansion device 6, and then enters the evaporator 7, and the refrigerant evaporates and absorbs heat. The exchange provides the production of ice water, which can be used by the external air conditioner 3. [0003] Please refer to the structure diagram of the conventional cooling tower 1 shown in Fig. 2, at least above the top surface of the cooling tower 1. An inverter fan 8 is disposed below the side of the cooling tower 1 with an air inlet 9 in which a sprinkler pipe 10 is disposed and connected to an inlet pipe 11 which is connected to a cooling water pump 12' and the cooling The bottom of the water tower 1 is provided with a water tank 13 for collecting cooling water. The water tank 13 is connected to an outlet water pipe 14, whereby the variable frequency fan 8 can drive air to be poured into the cooling water tower 1 from the air inlet 9 and above the cooling water tower 1 when the inverter fan 8 is in operation. Discharge, while cooling water is cooled by a water pump 12 The water inlet pipe 11 is driven into the cooling water tower 1 to be sprayed by the sprinkler pipe 10 to be dispersed in the cooling water tower 1, and then collected by the water tank 13 and discharged from the water outlet pipe 14 to the cooling water pump 12, so that the cooling water is sufficiently mixed with the air. In order to remove the heat by evaporation, the cooling water is cooled. [0004] Please refer to the figure shown in Figure 3, which affects the cooling performance of the cooling tower 1, mainly including the external atmospheric wet bulb temperature and the inflow and outflow of cooling water. Temperature difference 100117163 Form No. A0101 Page 3 of 23 1002028873-0 201248095 The flow rate of cooling water, as shown in Figure 3, has a cooling water flow of 100%, and different inlet and outlet water temperature differences have different performance. Curves (different flow rates also have different performance curves). For example, when the ambient atmospheric wet bulb temperature is 29 °C and the inlet and outlet water temperature difference is 5 °C, the lowest effluent temperature that can be reached is 32 °C, which is representative. The outlet water temperature for the cooling tower 1 can only reach 32 ° C at the minimum, and when the outlet water temperature is set lower than 32 ° C, only the variable frequency fan 8 of the cooling tower 1 is inefficiently operated and consumes energy. [0005] [0006] Therefore, proper water tower temperature control of the cooling tower 1 can improve the power efficiency of the cooling tower 1 and the ice water host 2, and achieve energy saving requirements. Currently, for the cooling water tower 1 outlet water temperature control, the atmospheric wet bulb temperature + Δ T mode is generally used. When the temperature of the outlet water of the cooling water is controlled, that is, when the temperature of the atmospheric wet bulb changes (such as the change of the four seasons and the change of the day and night), the setting of the outlet water temperature will also change to avoid the variable frequency fan 8 of the cooling tower 1 being unprofitable for a long time. Full load operation. However, please refer to “Figure 4”. Due to this outlet water temperature setting control method, only the change of atmospheric wet bulb temperature is considered, and the cooling water inlet and outlet water temperature difference and cooling water flow rate are not taken into account. The inverter fan 8 of 1 also has an unproductive full-load operation problem. As shown in Fig. 4, the operating frequency 15 of the inverter fan 8 of the cooling tower 1 is continuously full-loaded (60 Hz), and the actual outlet temperature value is 16 The phenomenon that the outlet water temperature setting value 17 is not generated (the actual outlet water temperature value 16 is higher than the outlet water temperature setting value 17), obviously this type of outlet water temperature setting Conditions due to changes of formula, resulting in the set value has an error, it does not prevent the full operating frequency cooling tower fan 8 of invalid benefits, resulting in energy.

[0013] [0013] 100117163 According to this, the present invention simultaneously considers three parameters, such as cooling water flow rate, atmospheric wet bulb temperature and cooling water temperature difference, which affect the performance of the cooling tower and allows it to be input into the cooling tower performance. The calculation function can calculate the minimum outlet water temperature that meets the performance of the cooling tower, and set the water outlet temperature of the cooling tower to prevent the outlet water temperature of the cooling tower from being set too low, thereby avoiding the inefficiency of the inverter fan of the cooling tower. It consumes energy when fully loaded, and saves the power consumption of the cooling tower to meet the needs of energy saving and environmental protection.

Form No. A0101 Page 6 of 23 ln 201248095 [0014] S1 [0016] S2 [0017] S3 [0018] S4 [0020] The apparatus of the present invention comprises a cooling water The flow calculation module 40, the at least one wet bulb temperature sensor 50, the at least one inlet and outlet water temperature sensor 60, and the control method of the present invention include: 51: calculating a cooling water flow rate; 52: detecting an atmospheric wet bulb temperature; 53 : Obtain the temperature difference of the cooling water; 54 : Calculate the minimum outlet water temperature; Set the outlet water temperature. The method of the present invention is achieved by the device of the present invention and is described as follows [0021] The cooling water flow calculation module 40 is configured to detect the operating frequency of the cooling water pump 24 of the cooling water tower 20 and multiply by the rated flow rate. The cooling water flow rate, and the cooling water pump 24 of the cooling water tower 20 may be plural.

The water flow rate and the cooling water flow calculation module 40 can be disposed in the controller 70 in combination. The flow of cooling water can be periodically detected by an ultrasonic flowmeter (not shown), and the calculated value can be compensated to ensure the correct flow of cooling water. [0022] The at least one wet bulb temperature sensor 50 is disposed at the air inlet 21 of the cooling water tower 20, and detects the atmospheric wet bulb temperature. The at least one wet bulb temperature sensor 50 can be set to be averaged, such as the wet bulb temperature perception 100117163 Form number Α 0101 Page 7 / Total 23 page 1002028873-0 201248095 The device 50 can be two and set in the cooling The air inlet 21 of the water tower 20 can be calculated on average to reduce the amount of error, and the atmospheric wet bulb temperature can be periodically compared and compensated by a portable wet bulb temperature sensor (not shown).

The minimum water outlet temperature of the cooling water tower 20 is calculated by the water temperature difference, so that the minimum outlet water temperature is set as the outlet water temperature setting of the cooling water tower 20. Here, it is worth mentioning that the performance curve calculation function is related to the design of the cooling water tower 20. It is usually provided by the designer of the cooling tower 20, and the performance curves of the different cooling towers 20 are different. Please refer to FIG. 7 , which is a running mode of the control mode inverter fan 30 for setting the water outlet temperature of the cooling water tower 20 by the present invention. As shown in the figure, the operating frequency of the inverter fan 30 of the cooling tower 20 of the present invention is 80. There is no phenomenon of continuous full load operation (60 Hz), that is, the actual water outlet temperature value 81 of the present invention can reach the outlet water temperature setting value 82. Obviously, the outlet water temperature setting mode of the present invention can surely avoid the inverter fan 30 of the cooling water tower 20. The full-load operation of the benefit 'avoids the phenomenon of energy consumption' to save energy and meet the needs of use. 100117163 Form No. A0101 Page 8 of 23 1002 201248095 [0026] Please refer to the table below, which is a comparison table between the present invention and the prior art (see Annex 1 for detailed experimental conditions and contents).
