Embodiment Construction
[0031] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0032] The air-conditioning and refrigeration integrated system provided by this application can be used in office business groups, hotel groups, commercial centers, residential areas and other places equipped with LNG gasification stations nearby. LNG gasification stations usually include terminal-type receiving stations or satellite stations, both of which can gasify LNG and supply it to users. The air-conditioning and refrigeration integrated system provided by this application cooperates with the LNG gasification station, which can recover the cold energy released duri...

The invention relates to an air conditioner refrigeration integrated system which comprises an LNG (liquefied natural gas) cold energy recovery sub-system, an electrical refrigeration host and a coldstorage device, wherein the LNG cold energy recovery sub-system and the electrical refrigeration host can supply cold to the air conditioner or the cold storage device. The cold storage device can store cold through the LNG cold energy recovery sub-system or the electrical refrigeration host or by combining two cold sources to supply cold energy, and can supply cold to the air conditioner. With aplurality of operation conditions of cold supply or cold storage, the system can flexibly select the operation condition according to the cold demand of a user as well as the cold supply of the LNG cold energy recovery sub-system, the electricity price peak-valley periods and the cold storage in the cold storage device, so as to sufficiently and effectively utilize the cold energy generated by LNGgasification.
Description
technical field [0001] The present application relates to the technical field of cold energy storage and utilization, in particular to an air-conditioning and refrigeration integrated system. Background technique [0002] As a clean and efficient energy source, the consumption of natural gas in my country has grown rapidly in recent years. Liquefied natural gas (LNG) is a liquid formed when natural gas is purified and cooled to -162°C, which is convenient for storage and transportation. LNG needs to be gasified before it can be used. The gasification process can release a large amount of cold energy, which is usually discarded, resulting in a lot of energy waste and environmental pollution. [0003] Based on this, there has been a technology to recycle the cold energy released by LNG gasification for air conditioning and cooling. This scheme can utilize the originally discarded cold energy and reduce the cold pollution caused by LNG gasification, which has the effect of sa...
