Title:

REFRIGERATION CYCLE DEVICE

Document Type and Number:

WIPO Patent Application WO/2015/056333

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide a refrigeration cycle device capable of inhibiting a heating medium from heating a refrigerant in a condenser when the temperature of the heating medium prior to being heated is high. This refrigeration cycle device is provided with: a first condenser; a second condenser of which the refrigerant flow path has a smaller cross-sectional area than the first condenser and which further condenses the refrigerant that passed the first condenser; a heat medium flow path for passing a heat medium through the second condenser and the first condenser in said order; a second condenser bypass path which bypasses the refrigerant flow path of the second condenser or the heat medium flow path; a flow path control element which can change the bypass amount of the refrigerant or the heat medium that bypasses the second condenser; and a control means for controlling the flow path control element so that the bypass amount is increased when the temperature of the heat medium prior to exchanging heat with the refrigerant is high.
