Computer room air-conditioning system performing combined operation of phase change thermal energy storage, natural cold source and artificial cold source

Abstract

The invention provides a computer room air-conditioning system performing combined operation of phase change thermal energy storage, a natural cold source and an artificial cold source, and relates to a computer room air-conditioning system performing combined operation of phase change thermal energy storage, the natural cold source and the artificial cold source. The computer room air-conditioning system comprises a phase change thermal energy storage device (1), an outdoor air cooling device (2), an air-conditioning water chilling unit (3), an indoor fan coil (4), a circulating water pipe (5) and an intelligent expert control system (6). The expert control system controls the time-sharing mutual combined operation of the indoor fan coil, the natural cold source equipment, the artificial cold source equipment and the phase change thermal energy storage device according to a set temperature of a computer room and an indoor environmental temperature, so that the natural cold source can be utilized fully and effectively; time-shifting application of energy is realized through phase change thermal energy storage, and efficient energy storage is conducted by utilizing valley-price electricity at night; and artificial refrigeration equipment is enabled to operate efficiently. The computer room air-conditioning system provided by the invention has high efficiency, saves energy, protects the environment and is economical in operation.

Description

technical field [0001] The present invention relates to a computer room air conditioning system that operates in combination with phase change energy storage and natural and artificial cold sources, and belongs to the technical field of air conditioning and new energy. Background technique [0002] With the continuous and rapid development of my country's information industry and economic scale, the rapid increase of communication equipment rooms, base stations, network data equipment rooms, and internal heat sources with high power, the energy consumption of equipment in the equipment room is concentrated and concentrated, and the continuous and uninterrupted operation, the power consumption is getting higher and higher. The huge power consumption will eventually become the heat load of the air-conditioning equipment in the computer room, which will lead to a sharp increase in air-conditioning energy consumption. The energy consumption of air-conditioning has reached 40-50% o...

Problems solved by technology

However, some technologies have potential hidden dangers and technical limitations

For example, the dust particles brought by the intelligent ventilation system after running for a long time have seriously affected the cleanliness of the computer room, forming a potential safety threat; the intelligent heat exchange system has a complex structure due to the characteristics of the air-to-air heat exchanger, which is easy to be blocked, and the later operation The maintenance workload is very large, which has attracted great attention from information operators; the heat pipe air conditioner also has technical limitations that cannot fully utilize the natural cold source of the temperature difference between day and night
