Problems solved by technology

The cold source of the traditional ice storage air conditioning system is relatively single. Electric refrigeration units are usually used. The ice storage device is composed of one or more ice tanks. When the system is running, different ice tanks store or release cold at the same time.
When the system introduces other cold sources, the single operation mode of the ice tank cannot meet the requirements of different cold sources working together
[0003] The LNG gasification process will generate a large amount of cold energy, and most of this cold energy is wasted at present, resulting in a waste of resources

Abstract

The invention provides an ice storage air-conditioner system capable of realizing LED cold energy recycling. The ice storage air-conditioner system comprises a cold recovery system, an ice storage device, an air-conditioner load side system, a first ice storage pump, and a refrigeration unit. The ice storage air-conditioner system has the advantages of realizing recovery, storage and utilization of cold energy, saving resources, and improving the utilization rate of the cold energy. Moreover, due to the fact that the LNG cold energy can be cooperated with the refrigeration unit to provide cold, the ice storage air-conditioner system not only can meet the requirements of a user for utilization of an air-conditioner system, but also can sufficiently utilize various resources, and plays an active role in effectively reducing energy consumption.

Description

technical field [0001] The invention relates to a cold energy storage and utilization device, in particular to an ice-storage air-conditioning system capable of realizing recovery and utilization of LNG cold energy. Background technique [0002] The ice-storage air-conditioning system is an air-conditioning system that uses low-valley electricity prices to store ice at night, and melts ice for cooling during daytime peak electricity prices, thereby reducing operating costs and balancing power grid loads. The traditional ice storage air-conditioning system has a relatively single cold source, usually using an electric refrigeration unit. The ice storage device is composed of one or more ice tanks. When the system is running, different ice tanks store or release cold at the same time. When the system introduces other cold sources, the single operation mode of the ice tank cannot meet the requirements of different cold sources working together. [0003] The LNG gasification pr...
