A saline solution dehumidifying and regenerating circulation loop is arranged between the solution dehumidifying unit and the solution regenerating unit, a first heat exchange circulation loop is arranged between the solution dehumidifying unit and the inner cold humidifying heat exchange unit, a second heat exchange circulation loop is arranged between the solution regenerating unit and an external hot water pipeline, and a first spraying and humidifying circulation loop is arranged between the heat insulating and humidifying heat exchange unit and an external tap water pipeline. A third heat exchange circulation loop is arranged between the inner cold air water heat exchange unit and a water return pipeline of a water utilization system, and a second spraying and humidifying circulation loop is arranged between the inner cold humidifying heat exchange unit and the external tap water pipeline. The air saline solution cold water unit has the advantages of being simple in structure, low in cost, stable in operation and high in energy efficiency ratio.

Description

technical field [0001] The invention relates to the field of cold water preparation in the field of industrial cooling or air conditioning, in particular to an air salt solution chiller using air as a heat exchange medium. Background technique [0002] In the field of industrial refrigeration, cooling and air conditioning, it is usually necessary to provide chilled water by refrigeration equipment to meet production or living needs. Traditional refrigeration equipment usually adopts the heat pump method, which is mainly composed of compressors, evaporators, condensers, expansion valves and other components, and the refrigerant circulates in it. During the cycle operation, the refrigerant is converted between gas and liquid through the compressor and expansion valve. When the temperature rises, the heat is released through air, water and other media; on the other hand, the refrigerant will absorb heat at the evaporator, which will reduce the temperature of the water in the w...

Problems solved by technology

[0003] The refrigeration equipment with the heat pump as the main working component not only consumes a large amount of electric energy in the actual operation process, resulting in waste of high-grade energy, but also makes the refrigeration equipment work at a low evaporation temperature for a long time, resulting in a lower coefficient of performance of the refrigeration equipment. Low, resulting in lower overall energy efficiency ratio of the unit

Experiments have shown that the energy efficiency ratio of refrigeration equipment based on heat pumps is relatively low, which is not conducive to the sustainable development and utilization of energy.
