As shown in fig. 1, the present embodiment provides a cooling and heating system of a data center, which includes a power supply terminal 1, a cooling device, a data room 3, and a heating device. The power supply end 1, the refrigeration equipment and the data machine room 3 form a refrigeration system of the data center; the power supply end 1, the data machine room 3 and the heating equipment form a heating system of the data center.
In a specific implementation mode, for example, summer, outdoor temperature is higher, and data computer lab 3 is difficult for the heat dissipation, and when needing to consume more energy and reduce data computer lab 3's temperature, refrigerating system refrigerates data computer lab 3 to refrigerate data computer lab 3 fast effectively, thereby guarantee data computer lab 3 normal stable work. For example, in winter, autumn and spring, the data room 3 may be cooled by natural cooling because the outdoor temperature is not high. However, because the data center generates more heat during operation, the natural cooling method is not enough to keep the data center in a normal temperature range, and the cooling equipment is still required to perform auxiliary cooling on the data center. At the moment, the refrigerating process of the data center releases more heat, and the heating system mainly utilizes waste heat of the data center to form a heat source for a community or a municipal pipe network, so that the utilization rate of energy is improved.
Specifically, the refrigeration equipment is electrically connected with the power supply end 1, and the power supply end 1 supplies power to the refrigeration equipment so as to ensure the normal operation of the refrigeration equipment. The refrigeration equipment comprises a cold water main machine set 21, a water supply pipeline 22, a water return pipeline 23 and a cold accumulation tank 24, wherein the cold water main machine set 21 is connected with the data machine room 3 through the water supply pipeline 22, and the cold water main machine set 21 is configured to refrigerate a cooling medium and output the cooling medium through the water supply pipeline 22. For example, the cooling medium cooled by the water chilling unit 21 is chilled water, and the chilled water is configured to supply cold to the data center and form return water, that is, the water forms chilled water in the water chilling unit 21 and is then conveyed to the data room 3 through the water supply pipeline 22, the chilled water cools the data room 3, and the temperature of the chilled water itself rises to form the return water. Data computer lab 3 passes through return water pipeline 23 with cold water host computer unit 21 is connected, cold water host computer unit 21 is configured as and passes through return water pipeline 23 receives coolant, and coolant in the return water pipeline 23 is the backward flow water, and the temperature of backward flow water is higher than the temperature of refrigerated water, and the backward flow water has carried the used heat that data center produced, and the backward flow water carries to cold water host computer unit 21 through return water pipeline 23 and carries out cooling once more to form the refrigerated water, the refrigerated water can refrigerate data computer lab 3, thereby realizes the water cycle between cold water unit and the data center, and data center realizes refrigeration or cooling at water cycle's in-process.
The cold storage tank is connected to the cold water main unit 21 and the data machine room 3 through the water supply pipeline 22, and is configured to store the cooling medium, i.e., chilled water, having a relatively low temperature output from the cold water main unit 21 or to supply the cooling medium, i.e., chilled water, having a relatively low temperature to the data machine room 3. In a first power supply state, the cold storage tank is configured to store the cooling medium output by the cold water main unit 21; in a second power supply state, the cold storage tank is configured to supply cooling medium to the data room 3. That is, the cold storage tank is used for storing chilled water in the first power supply state so as to output the chilled water to the data room 3 in the second power supply state, so as to meet the refrigeration requirement of the data room 3 in the second power supply state.
For example, the first power supply state may be a power consumption valley period, i.e., 23:00 to 7:00 the next day. Because this time quantum power consumption is less, and the charges of electricity are lower, and power supply end 1 can guarantee that data computer lab 3 and refrigeration plant's power supply is sufficient, and at this moment, cold-storage jar 24 can utilize the electric power of power consumption valley period to store the cold volume of cold water host machine unit 21 preparation with the form of refrigerated water to supply cold to data computer lab 3 at the power consumption peak, with the refrigeration efficiency of assurance data computer lab 3 at the power consumption peak.
The first power state may be a power peak period, i.e., 7:00 to 23: 00. Because this time quantum is the peak load of power consumption, not only the expense is higher, and the power consumption state is unstable moreover, and data center very easily appears because the power supply is not enough to lead to data center's refrigeration effect not good, at this moment, irritates to data center through cold storage and carries the refrigerated water, helps alleviating the cooling pressure of cold water host computer unit 21 to data computer lab 3 at the power consumption peak to further improve data center's refrigeration effect, guarantee data center's normal operating.
It should be noted that the first power supply state and the second power supply state may also be set according to the actual operation state of the data center, so as to implement that the cold storage tank stores chilled water in the first power supply state, and deliver chilled water to the data center in the second power supply state, thereby ensuring the refrigeration effect of the data center, and enabling the data center to operate stably. The present disclosure does not limit specific time points of the first power supplying state and the second power supplying state.
For example, the power consumption of all the electric equipment such as the data center, the refrigeration equipment, the heating equipment and the like, which can ensure that the data center works normally, is set as a preset electric quantity, the electric quantity provided by the power supply terminal 1 is larger than the preset electric quantity to be in a first power supply state, at the moment, the cold quantity provided by the cold water host machine set 21 is enough to meet the refrigeration requirement of the data center, and the cold storage tank stores part of the chilled water output by the cold water host machine set 21; when the electric quantity provided by the power supply end 1 is smaller than the preset electric quantity and is in a second power supply state, the cold quantity provided by the cold water host machine set 21 is not enough to meet the refrigeration requirement of the data center, and the cold storage tank outputs chilled water to the data center, so that the refrigeration effect of the data center is further improved, and the normal operation of the data center is ensured.
Chilled water is stored in the first power supply state through cold storage irrigation to carry the chilled water to data center in the second power supply state, can effectively reduce the installation quantity of cold water host unit 21, reduce the working costs, realize that power load's peak clipping fills in the millet, guarantee data center's normal operating.
When the chilled water stored in the cold accumulation tank is not discharged in time, the temperature of the chilled water inside the cold accumulation tank can be increased, and the chilled water cannot be conveyed to a data center. Therefore, in this embodiment of the application, the cold storage tank is further connected to a return water pipeline 23, and the water after warming up in the cold storage tank is conveyed to the cold water main unit 21 through the return water pipeline 23 for cooling down.
Further specifically, the heating equipment is electrically connected with the power supply end 1, and the power supply end 1 supplies power to the heating equipment; the heating device comprises a heat pump unit 41, a heating end 42 and a first connecting branch pipe, the heat pump unit 41 is connected with the water return pipeline 23 through the first connecting branch pipe, the heat pump unit 41 is configured to heat a cooling medium in the first connecting branch pipe and form warm water supply to be conveyed to the heating end 42, and the warm water supply is output through the heating end 42. The heat supply end 42 is connected to the heat pump unit 41, the heat pump unit 41 can heat the cooling medium that is branched to the first connecting branch pipe by the return line, and the heated cooling medium is output by the heat supply end 42. Because the cooling medium in the return line absorbs the heat generated by the data machine room 3, the temperature of the cooling medium is higher, and the cooling medium in the return line is heated and then output to the heat supply end 42, so that the heat generated by the data machine room 3 is favorably used for heating communities and the like, the utilization rate of resources is improved, and the energy is favorably saved.
When the temperature of the cooling medium in the return pipeline, namely the return water, is high, the return water can be directly output through the heating end without heating the return water by using the heat pump unit 41, so that the heat generated in the operation process of the data center is taken as a heat source for heating a community and the like, the energy recycling is realized, the utilization rate of energy is improved, and the energy saving is facilitated.
For example, in spring, autumn or winter, the data computer lab 3 is mainly natural cooling, and the refrigeration power consumption of the refrigerating system of the data computer lab 3 reduces, utilizes power supply end 1 to supply power to heat pump set 41, makes heat pump set 41 heat some high-temperature backflow water, forms warm water supply, can heat whole district, also can directly access municipal heating pipeline, utilizes the used heat that data center produced to form the heat source and realizes recycling, is favorable to improving the utilization ratio of the energy.
Optionally, the heating end 42 is connected to a district heating pipe. The heat supply end 42 is directly connected to the district heating pipe, and the district heating pipe is supplied with warm water by the heat supply end 42 to realize heating of the district. In winter and other times with lower temperature, the district is heated by utilizing the heat generated by the data center, so that the utilization rate of energy is improved, and the energy is saved.

Alternatively, the heat pump unit 41 includes a plurality of heat pump units. The plurality of heat pump units can significantly improve the heating effect of the heat pump unit 41 to quickly and efficiently heat the cooling medium that enters the heat pump unit 41 through the first connecting branch pipe. The stability of heating of the heating end 42 is realized.
In this embodiment, because data computer lab 3 produces a large amount of heat in the process of operation, through carrying the refrigerated water to data computer lab 3 and cooling down data computer lab 3, the refrigerated water rises through 3 temperature of data computer lab and forms the backward flow water, realizes data computer lab 3's energy circulation through supply line 22 and return water pipeline 23. The return water with higher temperature is formed into warm supply water through the heat pump unit 41 and is output through the heat supply end 42. The heating of residential areas and the like is realized by utilizing the energy carried by the backflow water, the heat generated by the data machine room 3 is effectively utilized, and the energy is saved.
Namely, the data machine room 3 is rapidly and effectively cooled by the refrigeration equipment in seasons with high temperature such as summer, so that the data machine room 3 can stably run; through the season that the temperature is lower such as winter, because data computer lab 3's natural cooling effect is better, data computer lab 3's refrigeration plant's power consumption is less, at this moment, form warm water supply after the higher cooling medium of temperature through forming data computer lab 3 refrigeration back heats promptly the backwash water, supply heat supplies such as district with output to heat supply end 42, not only can guarantee data computer lab 3's normal operating, moreover, can realize the reuse of used heat, be favorable to the energy saving, the utilization ratio of the energy improves.
