<P>PROBLEM TO BE SOLVED: To prevent refrigerant from freezing and prevent inner corrosion of components, while preventing an increase in the amount of adsorbent to be supplied. <P>SOLUTION: A drier 10 for refrigerating cycle is applied to a vapor compression type refrigerating cycle through which a refrigerant including HFO-1234yf flows. A highly water absorptive resin having an adsorption characteristic in which a degree of increase in moisture adsorbing rate is increased due to increase in relative humidity, is employed as an adsorbent. As a result, the increase in moisture permeation speed can be suppressed compared to a zeolite or the like. The moisture amount in the refrigerant can be efficiently lowered, and the inner corrosion of components can be suppressed. By combining a refrigerant characterized to prevent an inclusion compound from being generated by reacting water, and the highly water absorptive resin which exhibits a low adsorption performance when the water concentration in the refrigerant is low, the refrigerant is prevented from freezing, while preventing an increase in the mount of adsorbent to be supplied. <P>COPYRIGHT: (C)2013,JPO&INPIT |
