Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2015/029160
Kind Code:
A1
Abstract:
This air conditioner is characterized by the provision of a refrigerant circuit in which a compressor, a first heat exchanger, a first throttling device, and a second heat exchanger are connected together. The air conditioner is also characterized in that: the compressor and the first heat exchanger are accommodated inside a heat-source device; the first throttling device and the second heat exchanger are accommodated inside a housing; the heat-source device and the housing are connected to each other via a plurality of extension pipes that constitute part of a system of refrigerant piping; the heat-source device also accommodates a second throttling device that is provided downstream of the first heat exchanger and upstream of the first throttling device; the second throttling device is connected to the first throttling device via one of the aforementioned extension pipes, namely a first extension pipe; in an air-conditioning mode, the second throttling device reduces the pressure of a refrigerant before said refrigerant flows into the first extension pipe, putting the refrigerant in a two-phase state at an intermediate pressure that is lower than the pressure of the refrigerant inside a condenser and higher than the pressure of the refrigerant inside an evaporator; and in the air-conditioning mode, the refrigerant is made to flow through the first extension pipe in the aforementioned two-phase state at the aforementioned intermediate pressure.
