Problems solved by technology

[0004] In large-scale buildings integrating data computer rooms and offices, such as banks, securities exchanges, futures transactions, network computer rooms, and computer centers, in order to save operating costs by using low-peak power at night, non-data computer room areas (i.e. office areas) adopt cold storage air conditioning systems , while the data room mostly adopts a cold water cooling system with an emergency water storage tank, the two cooling systems are independent of each other, and in non-cooling seasons such as transitional seasons and winter, the cold storage tank in the cold storage air conditioning system is usually in an idle state, Caused a waste of resources and failed to meet the needs of practical applications

Embodiment 1

[0024] Such as figure 1 As shown, the present invention provides a cooling system for a data center, including a cold storage tank cooling system 100 and an air conditioner cold water circulation system 200 . It should be noted that, for a building that integrates a data computer room and a non-data computer room, the cold storage tank cooling system 100 is installed in the non-data computer room's freezing station, and the air-conditioning cold water circulation system 200 is installed in the data computer room's freezing station.

[0025] The cold storage tank cooling system 100 includes a cold storage tank 102, a cooling pump P1 and a heat exchanger 103, and the cold storage tank 102, the cooling pump P1 and the heat exchanger 103 are sequentially connected through a cooling pipeline 101 to form a cooling circuit , the cooling pump P1 is connected to the outlet of the cold storage tank 102; specifically, the working process of the cold storage tank cooling system 100 is as ...

Embodiment 2

[0032] The difference from Embodiment 1 is that there are two chilled water pumps P2 in Embodiment 2, that is, chilled water pumps P21 and P22, which are connected in series with the heat exchanger 103 and the refrigerating unit 202 respectively, that is, the chilled water pump P21 and the heat pump P21 are connected in series. The outlet of the exchanger 103 is connected, and the chilled water pump P22 is connected to the outlet of the refrigeration unit 202. At this time, in order to save parts, the first gate valve V1 and the second gate valve V2 can be omitted, as shown in figure 2 As shown, the cooling state of the heat exchanger 103 is controlled by turning on or off the chilled water pump P21, and the cooling state of the refrigeration unit 202 is controlled by turning on or off the chilled water pump P22. When one of the chilled water pumps P21 or P22 fails or is overhauled, the system can still be guaranteed to operate normally, further improving the reliability of th...

Abstract

The invention discloses a data computer room cooling system and a cooling method thereof. The data computer room cooling system comprises a cold storage tank cold discharging system and an air conditioner cold water circulating system. The cold storage tank cold discharging system comprises a cold storage tank, a cold discharging pump and a heat exchanger which are sequentially connected to form a cold discharging loop. The cold discharging pump is connected with an outlet of the cold storage tank. The air conditioner cold water circulating system comprises a heat exchanger, a refrigerating unit, a freezing water pump and end equipment. The cold storage tank cold discharging system and the air conditioner cold water circulating system are connected through the heat exchanger of the air conditioner cold water circulating system is connected with the refrigerating unit in parallel. The heat exchanger of the air conditioner cold water circulating system, an outlet of the refrigerating unit, the freezing water pump and the end equipment are sequentially connected to form a cooling loop. The heat exchanger of the air conditioner cold water circulating system is connected with a first valve in series, and the refrigerating unit is connected with a second valve in series. When the refrigerating unit loses power and stops running, the cold storage tank cold discharging system is started, and normal cooling can be carried out; an extra water cold storage tank does not need to be arranged, cost and space are reduced, and operation cost of the data computer room cooling system is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration and air conditioning, in particular to a cooling system for a data machine room and a cooling method thereof. Background technique [0002] The data room is equipped with computer systems, servers, communication systems and other data processing, storage, and network communication equipment that operate 24 hours a year. The above equipment generates a lot of heat, causing the temperature in the data room to rise. In order to ensure the normal operation of the equipment , requires uninterrupted cooling throughout the year, and requires the cooling system to have extremely high reliability and save energy consumption. [0003] In A and B-level data computer rooms, cold water cooling systems are usually used for cooling. At the same time, in order to ensure the safety and reliability of power consumption in the computer rooms, a diesel generator power supply system is installed as a backup for ...
