Description

Technical Field

[0001] The utility model relates to the technical field of cold source supply for data centers, in particular to an air-cooled cold water refrigeration energy-saving regulating and controlling device for data centers. Background Art

[0002] Air-cooled central air conditioning is one of the common forms of central air conditioning systems. It absorbs or dissipates heat in the air through a heat absorber to achieve the purpose of heating or cooling. As one of the earliest forms of air conditioning, air-cooled central air conditioning technology is mature and easy to maintain. With the development of network technology and the acceleration of informatization, air-cooled chillers are refrigeration equipment that uses low-grade energy from nature and uses air as a cooling medium in various Internet data centers and cloud computing data. They are often used in data centers, server rooms and other equipment.

[0003] Existing air-cooled chillers usually use external fresh air as the medium, and use the outdoor fresh air to cool the evaporator surface to achieve the purpose of lowering the water temperature. At the same time, the outdoor air enters the indoor circulation system through the filter to achieve the cooling effect. However, in actual use, since the temperature of the cold water will gradually increase during the exchange and heat exchange process, refrigeration regulation is required to continuously cool the cold water to maintain the fresh air cooling effect. Refrigeration regulation consumes more electricity, has relatively insufficient energy-saving capacity, and consumes a lot of energy. For this reason, we propose an energy-saving regulation control device for air-cooled chilled water refrigeration in data centers to solve the above problems. Utility Model Content

The circuit connection relationship of each device belongs to a simple series and parallel connection circuit. There is no innovation in the circuit connection. Those skilled in the art can easily implement it. It belongs to the existing technology and will not be elaborated.

[0043] Working principle: by arranging a fresh air-cold air heat exchange component 6 in the main body 2 of the water chiller heat exchange tank, the fresh air introduction pipe 1 introduces the external fresh air into the fresh air-cold air heat exchange component 6. During the conduction of the fresh air in the fresh air-cold air heat exchange component 6, the heat carried by the fresh air can be quickly cooled down by the cold water in the main body 2 of the water chiller heat exchange tank, and the fresh air can be quickly cooled down, and the air cooling effect is good. The cold water in the main body 2 of the water chiller heat exchange tank and the temperature difference exchange box 3 are filled and connected. When the cold water temperature in the main body 2 of the water chiller heat exchange tank When the temperature becomes high, due to the heat convection phenomenon of the hot air rising and the cold air falling in the water, the hot water in the water chiller heat exchange tank body 2 is guided to the temperature difference exchange box body 3 by the cold water temperature difference circulation exchange component 4, and the cold water in the cold water temperature control component 5 can fall into the water chiller heat exchange tank body 2, achieving the effect of cold and hot water convection circulation, thereby maintaining the temperature balance of the cold water, similar to the working principle of the solar water heater, so that the cold water does not need to be refrigerated for a long time, greatly reducing the power consumption, with good energy saving effect and less energy loss;

When the temperature is high, the temperature detector 52 can control the switch of the control valve 55 after detecting the temperature, and the hot water is discharged from the water outlet pipe 54.

The control valve 55 plays a role in switch control and water source diversion control. After the hot water is discharged, cleaning and other operations can be carried out. The cold water temperature is kept constant, the overall power consumption is small, and the energy saving effect is good.

[0045] The cold water standby box 51 is a heat preservation box with good constant temperature effect, and the temperature detector 52 is electrically connected to the control valve 55, so that when the temperature detector 52 detects a high temperature, it can directly control the control valve 55 to switch, and the hot and cold water exchange is relatively convenient.
