ABSTRACT:
A refrigerating cycle apparatus of an improved operating efficiency, which is constructed, in combination, with: a refrigerant circuit including an evaporator, a compressor, a condenser, a first throttle, an economizer for separating the refrigerant into a gas phase and a liquid phase, and a second throttle, all these component elements being interconnected in the order as mentioned; and a piping for the economizer, which connects the gas phase portion of the economizer and an intermediate pressure region of the compressor, wherein the length of the economizer is set in such a value that is greater than the values to be determined from a Mollier's diagram on the basis of the operating conditions for the refrigerating cycle apparatus for the increase in the cooling or warming capability as well as the increase in the coefficient of performance.
