According to the utility model discloses a hydrologic cycle formula cooling system is through addding three-way valve 6 in the hydrologic cycle pipeline for can only utilize second cooling tower equipment 5 to come to dispel the heat the cooling to the refrigerated water under the condition that for example the refrigeration demand is lower (for example, in the lower winter of temperature), make refrigerating machine equipment 2 be in standby state can, thereby can satisfy actual refrigeration demand and reduce entire system operation consumption. When the cooling demand increases (for example, the outside temperature increases), the cooling efficiency can be improved by increasing the number of the second cooling tower devices that are operated or increasing the wind speed of the fans of the second cooling tower devices, or the like. When the demand for cooling increases further (e.g., into a season of higher temperature), the chiller device 2 may be turned on to cool.

In a specific embodiment, the first cooling tower apparatus 3 may employ a closed cooling tower, but preferably employs an open cooling tower to improve heat dissipation efficiency. The basic working principle of the open cooling tower is as follows: the dry (low enthalpy) air is driven by a fan and enters a cooling tower through a water spraying filler; the water with damp heat (high enthalpy) is sprayed on the water spraying filler through a water spraying system. When water flow contacts with air, on one hand, due to direct heat transfer between the air and water, on the other hand, due to the pressure difference between the water vapor molecule surface and the air, an evaporation phenomenon is generated under the action of the pressure difference, heat in water is taken away in the form of evaporation latent heat, and the purpose of cooling is achieved through the evaporation heat transfer process.
In a specific embodiment, the second cooling tower apparatus 5 may employ an open cooling tower, but preferably employs a closed cooling tower to improve the quality of the circulating water. Closed cooling towers are a variation and development of conventional cooling towers. The water in the water storage tank at the bottom of the tower is pumped by a circulating pump and then is sent out of the pipe to be uniformly sprayed. The cooling tower is not contacted with process fluid hot water or refrigerant and air outside the pipe, so that the cooling tower becomes a closed cooling tower, and the heat and mass transfer effects are enhanced through spray water. The closed cooling tower is suitable for various cooling systems (such as the fields of electric power, chemical industry, steel, food and the like) with higher requirements on circulating water quality. On the other hand, compared with the air-cooled heat exchanger, the evaporative cooling tower has the obvious advantages that the heat transfer medium on the air side is obviously enhanced by using the latent heat of evaporation of water on the lower side of the pipe.
According to the utility model discloses a hydrologic cycle formula cooling system, winter through the control to the cooling tower, provides the cold volume that the system needs, need not open the host computer and refrigerate, and when partial outer gas temperature was higher, the automatic refrigerator that opens assists the refrigeration. In addition, an outdoor temperature and humidity sensor, a pipeline temperature sensor and an electric valve are additionally arranged on the site, and an original water channel system is modified, so that the switching and the isolation of the water system pipeline are completed through the electric valve.
For example, when cooling tower is used in winter, the average wet bulb temperatures in the outside air months for 12, 1, 2, and 3 months in suzhou are: 5.6 deg.C, 2.9 deg.C, 3.9 deg.C, 6.7 deg.C. In the months, the load demand can be met by adopting a cooling tower for cooling, and the system with lower chilled water supply temperature demand can adopt a refrigerator for auxiliary cooling.
In addition, because the change of the temperature difference between day and night, the temperature of the external wet bulb is higher in daytime and lower at night, the temperature of the freezing water provided by the cooling tower is changed, the automatic control system is adopted to adjust and control the operation of the system, and the temperature and humidity data collected by the outdoor temperature and humidity sensor are used for controlling the start and stop of the fan, the electric valve, the bypass valve and the water pump so as to meet the demand of the system and guarantee the operation stability of the system.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
