Data computer room cooling system and cooling method thereof

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 ...

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
