Abstract: In a composition for use in a refrigeration cycle which comprises at least a hydrofluorocarbon, a refrigerator oil, and a desiccating agent, the desiccating agent possesses a capacity for adsorption of difluoromethane of less than 2.77% by weight as determined by the McBain method. This desiccating agent is a sodium.potassium A type zeolite which has a sodium content of not less than 6% by weight, a potassium content of not less than 5% by weight, and a total sodium and potassium content in the range of from 13 to 20% by weight. Owing to the use of the desiccating agent of this quality, the water concentration in the refrigeration cycle can be lowered without entraining decomposition of such a Flon alternative as difluoromethane which is used in the place of dichlorodifluoroethane or monochloro-difluoromethane.

Abstract: A domestic electric appliance comprises a water purifier employing an electrodialyzer. The electrodialyzer includes an anode, a cathode, cation exchange films, and anion exchange films. The cation and anion exchange films are alternately arranged between the anode and the cathode and serve as partition walls. The domestic electric appliance further comprises a unit for using the water purified by the water purifier.

Abstract: A tap water processing apparatus comprises a water tank for storing tap water, and an ultrasonic oscillator disposed inside the water tank and emitting ultrasonic waves. The tap water contains hypochlorous acid components produced through a chlorine disinfecting process. When processed by the ultrasonic waves generated by the ultrasonic oscillator, the hypochlorous acid components are removed from the tap water.
