Embodiment 1

[0067] Embodiment 1 of the cross-season cold storage type cooling system of the present invention, as figure 1 shown. This embodiment can be applied to the year-round cooling of communication base stations, electronic equipment rooms, etc., consisting of cold storage device 1, first heat exchange device 2, first circulation pump 3, compressor 4, first condenser 5, and second circulation pump 6. Heat exchange equipment 7, second condenser 8, first throttling device 20, second throttling device 21, valve V 1 to V 9 , temperature collection point T 1 to T 4 . The coil-type cool accumulator 1 is filled with an effective volume of 80% ethylene glycol aqueous solution, and its mass concentration is 40%. Except for the cold storage device 1, other devices are connected through pipelines, and after vacuuming, they are filled with refrigerant R32 and lubricating oil. The system has five loops of primary cold storage, secondary cold storage, release cooling, natural cooling and re...

Embodiment 2

[0079] figure 2 The difference between the illustrated embodiment 2 and the embodiment 1 lies in the natural cooling circuit, and the others are the same. In this embodiment, the second condenser 8 in the natural cooling circuit adopts a closed spray cooler, and uses the evaporation and heat absorption of water to cool the heat exchange equipment 7. The advantage is that the heat exchange of the second condenser 8 can be reduced. temperature difference, prolong the natural cooling time, reduce the demand for cold storage capacity of the cold storage device, and save the initial investment.

Embodiment 3

[0081] Such as image 3 Shown, embodiment 3 is used for the cooling of wind power generating set. The cooling system consists of a cold storage device 1, a first heat exchange device 2, a first circulation pump 3, a compressor 4, a first condenser 5, a first throttling device 20, a second circulation pump 6, a second condenser 8, Second heat exchange device 12, expander 17, generator 18, gearbox heat exchanger 13, inverter heat exchanger 14, generator heat exchanger 15, wind turbine 16, temperature collection point T 1 , T 2 and T 3 .

[0082] The coil type cold storage device 1 is filled with an effective volume of 80% ethylene glycol aqueous solution, and its mass concentration is 40%. The first heat exchange device 2 , the first circulation pump 3 , the compressor 4 and the first condenser 5 are connected through pipelines, and filled with refrigerant R32 and lubricating oil after vacuuming. The second circulation pump 6, the second condenser 8, the second heat exchang...

Abstract

The invention discloses a seasonal cold-accumulation all-year cooling system and an operating method thereof, and belongs to the technical field of air conditioners. The system comprises a primary cold-accumulation loop, a secondary cold-accumulation loop, a cold-release cooling loop, a natural cooling loop and a refrigerating cooling loop. In winter, equipment is cooled by the natural cooling loop, and the primary cold-accumulation loop and the secondary cold-accumulation loop generate low-temperature cold energy to store during power consumption valley in winter. In summer and transition seasons, the equipment is cooled by the cold-release cooling loop, and the refrigerating cooling loop is reserved in summer. The seasonal cold-accumulation all-year cooling system utilizes a winter valley electricity price to refrigerate and store cold, is great in cold-storage density, is high in quality, and is suitable for cooling various kinds of electronic equipment, wind generating sets, data machine rooms, and the like.

Description

technical field [0001] The invention relates to a cross-season cold storage year-round cooling system and an operation method thereof, belonging to the technical field of air conditioning. Background technique [0002] Entering the 21st century, energy is in short supply, and environmental problems caused by pollutant emissions have become increasingly prominent. In recent years, the rapid development of mobile phone networks has led to a sharp increase in the number of communication base stations and end users. According to the report of the Ministry of Industry and Information Technology, as of October 2014, the number of 4G base stations nationwide was 700,000. As of February 2015, statistics from the Ministry of Industry and Information Technology show that the total number of mobile phone users reached 1.29 billion. The annual energy consumption of air conditioners accounts for 46% of the total energy consumption of the base station. Reducing the energy consumption of...
