Abstract
A method for constructing a refrigerating cycle that has a unit having a refrigerating compressor which is filled with a part or all of a quantity of working medium beforehand and a heat exchanger, and a unit having a heat exchanger that is located in an area of air conditioning and refrigeration, wherein the units are connected with each other by piping, uses such steps of: connecting the unit having the refrigerating compressor and heat exchanger with the unit having the heat exchanger that is located in an area of air conditioning and refrigeration by means of piping; removing oxygen in a system of the refrigerating cycle by providing an oxygen absorbent in a course of a refrigerant circulating path; separating the oxygen absorbent from the refrigerating cycle; and circulating a refrigerant in the refrigerating cycle, wherein the separating step is carried out immediately after or after the removing step, and the refrigerant circulating step is a final step.
