Abstract

A method of cooling and heating while dehumidifying by concentrating the dilute liquid (4) of a dehumidifying solution into a concentrated liquid (2) by means of solar heat or vacuum evaporation, and then using the concentrated liquid (2). A dilute liquid (4) obtained through dehumidification is heated through a heat exchanger (7), subjected to solar heat, and passed through a low temperature evaporator (11) and high temperature evaporators (13), (14) and (15), each of which is reduced in pressure via a vacuum passage (19), and through a heat exchanger (7) back to a concentrated liquid tank (1). This is essentially utilized to cool or heat the inside of a room (23) or the like while dehumidifying it. When solar heat is plentiful, the solution is concentrated or further solidified. By doing so, solar energy can be stored and utilized evenly thereafter.
