PURPOSE: To ensure water vapor partial pressure at ambient temperature and high partial pressure at a slightly higher temperature, by employing a salt solution having a specific composition as a working medium used for a method for indoor adsorption cooling/air conditioning with adsorption/desorption of water. CONSTITUTION: An absorption cooling/air conditioning circuit is employed, and its working medium is an aqueous hygroscopic salt solution containing 40 to 43% by weight calcium chloride, 15 to 25% by weight calcium nitrate, and 0.5 to 5% by weight an organic polyhydroxy compound in a loadless state or a regeneration state. A remaining component of the working medium is water, which is existent in a ratio of 100% by weight of the total sum of components of the working medium in a loadless state or in a working state. The polyhydroxy compound is assumed to be a C2 to C6 organic compound having two hydroxy compounds. The working medium has a deposit temperature lower than 20 deg.C. Thus, there is ensured safety of a normal pressure absorption cooling apparatus using an environmental protective cooling medium. |
