Abstract

The invention provides a freezing-based solution regeneration method and device, and belongs to the field of refrigeration and air-conditioning equipment. The scheme of the invention is as follows: partial water in a dilute solution with proper concentration is iced and separated out by utilizing the cold capacity of a refrigeration and air-conditioning system so as to obtain a concentrated solution; the dilute solution with proper concentration is transferred into a heat insulating housing to perform heat exchange with an evaporator, thus partial water in the dilute solution is iced, and the solution containing ice is introduced into an ice-solution separating device for separation, so as to obtain a regenerated concentrated solution; and the regenerated concentrated solution is conveyed outside. The device can be applied to equipment which needs a solution and has no solution regeneration function, such as a solution spraying type heat pump and a heat source tower, thus the solution spraying type heat pump, the heat source tower and the like can continuously run without high-capacity dilute solution storage tanks.

Description

technical field [0001] The invention relates to a freezing-based solution regeneration method and device, belonging to the field of refrigeration and air-conditioning equipment. The dilute solution of appropriate concentration enters the insulation shell containing the evaporator of the refrigeration system, and the water in the dilute solution is frozen into ice in the low-temperature solution regeneration unit by using the cooling capacity provided by the refrigeration system, and then separated out, so that the dilute solution becomes concentrated. The solution is then sent out. Background technique [0002] Energy has become an important factor restricting economic development. With the rapid development of the economy and the improvement of people's living standards, air-conditioning has become a necessity in people's life, a large energy consumer in buildings, and occupies a large part of the total energy consumption. share. [0003] At present, solution refrigeratio...
