Problems solved by technology

Its disadvantage is that the inner shell side of the LiBr evaporator absorbs heat and generates negative-pressure steam that enters the first-effect seawater desalination evaporator. High; seawater desalination depends on the steam provided by the air conditioning system, and seawater desalination cannot be performed when the air conditioning system is out of service. If the air conditioning system is idling, the service life of the air conditioning system will be reduced

Description

technical field [0001] The invention relates to a new energy technology, in particular to a high-efficiency solar desalination and air-conditioning refrigeration combined operation method and system. Background technique [0002] Seawater desalination, also known as seawater desalination and seawater desalination, refers to the process of removing excess salt and minerals in water to obtain fresh water. It is an open-source incremental technology to realize the utilization of water resources. The development and industrial application of seawater desalination technology has a history of half a century. During this period, industrial technologies mainly represented by multi-stage flash evaporation, multi-effect evaporation and reverse osmosis have been formed. [0003] Multi-effect evaporation is to evaporate the heated seawater in multiple evaporators in series. The steam evaporated from the previous evaporator is used as the heat source of the next evaporator, and condensed...
