ABSTRACT:
To provide a refrigerating cycle apparatus which uses carbon dioxide as a working medium, in which a problem associated with reliability arisen from introduction of water into a refrigeration cycle has been solved.Carbonic acid produced by a reaction of carbon dioxide or a mixed refrigerant including carbon dioxide and water is efficiently removed by providing a flow channel of the refrigeration cycle with a carbonic acid trapping agent, and consequently, the refrigerating cycle apparatus with high reliability which can prevent deterioration of a carbon dioxide refrigerant, decomposition of a refrigeration oil, corrosion of metal components or the like is constructed.
