Efficient energy-saving heat dissipation system for large-scale storage unit of electric power system machine room

Technical Field

The invention relates to the technical field of heat dissipation of machine rooms, in particular to an efficient energy-saving heat dissipation system for a large-scale storage unit of an electric power system machine room.

Background

Information equipment rooms such as data center rooms and core rooms are important places for placing communication electronic equipment. With the rapid development of industries such as global communication, internet of things, electronic commerce, cloud computing and the like, a large number of electronic information rooms are built for communication operators, governments, enterprises and the like. The electronic equipment in these rooms may continue to generate heat during operation. In order to ensure the normal operation of the information electronic equipment, a special air conditioner is generally installed in the electronic information machine room, and the information electronic equipment is cooled by the special air conditioner. The integration level of information electronic equipment is higher and higher, and the heat density of the information electronic equipment is also higher and higher, so that the load of a special air conditioner for a machine room is larger and larger, and the energy consumption is higher and higher. Under the same condition, the traditional machine room air conditioner can only increase the number of air conditioners or replace the machine room air conditioner with larger refrigerating capacity, so that the effective area of the machine room is reduced. Data show that the energy consumption of the information electronic equipment accounts for 45% of the overall energy consumption of the machine room at present, and the energy consumption of refrigeration equipment such as a special air conditioner of the machine room accounts for 40% of the overall energy consumption of the machine room, which directly drives the energy consumption of the information electronic equipment or exceeds the energy consumption of the electronic equipment. Therefore, by improving the refrigerating system of the communication machine room, the communication machine room still has a larger energy-saving space.

Chinese patent application No. CN201410755258.2 discloses an energy-saving machine room heat dissipation system, which comprises a precision air conditioner, a plenum box, an air return device, a full sensible heat exchanger, a cooling module and an intelligent server cabinet. The heat dissipation system is internally circulated by a precision air conditioner, a static pressure box, an intelligent server cabinet, an air return device and a full sensible heat exchanger. The heat dissipation system is composed of a full sensible heat exchanger and a cooling module to form external circulation. The internal circulation and the external circulation of the machine room are mutually coupled, and under the condition that the temperature of outdoor air is high, the temperature of air required by the server is reduced by the external circulation firstly, and then the air is reduced to a required nominal value by the precision air conditioner; in the case of low outdoor temperatures, the air required by the servers is directly circulated through the outside to the desired nominal value. The system can exchange heat between air with higher temperature in the machine room and air with lower temperature outside the machine room without influencing the internal environment of the machine room.

However, the system occupies a certain space inside the machine room, the heat island effect is easily generated, the temperature in the machine room is high, and the system cannot directly dissipate heat of the equipment in processing, so that the temperature of the surface of the working equipment is still high in the double-circulation process.
