Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/125219
Kind Code:
A1
Abstract:
This air conditioning device has: a first throttle device provided between a heat-source-side heat exchanger and a load-side throttle device; a bypass tube of which one end is connected between the first throttle device and the heat-source-side heat exchanger, and through which a refrigerant flowing out from the first throttle device flows; an auxiliary heat exchanger that cools the refrigerant flowing through the bypass tube and supplies same to the intake section of a compressor; a second throttle device that adjusts the flow rate of the refrigerant flowing from the auxiliary heat exchanger into the intake section of the compressor; and a control device that controls the aperture of a refrigerant flow path switching device, the first throttle device, and the second throttle device. The control device controls the first throttle device and second throttle device in a manner such that the refrigerant in a high-pressure state flows into the auxiliary heat exchanger when the heat-source-side heat exchanger is acting as a condenser or a gas cooler. Meanwhile, the control device controls the first throttle device in a manner such that the refrigerant in a medium-pressure state flows into the auxiliary heat exchanger when the heat-source-side heat exchanger is acting as a vaporizer, and controls the second throttle device in a manner such that the refrigerant cooled at the auxiliary heat exchanger flows into the intake section of the condenser.
