Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/026011
Kind Code:
A1
Abstract:
This refrigeration cycle device is equipped with a refrigerant circuit and a control device. The refrigerant circuit has an internal heat exchanger, an injection pipe, and a second expansion valve. The internal heat exchanger performs heat exchange between a first refrigerant, which is a refrigerant flowing out from a condenser, and a second refrigerant, which is a refrigerant branching into the injection pipe and expanded by the second expansion valve. The condenser performs heat exchange between the refrigerant flowing through the refrigerant circuit and a heat carrier passing through the condenser. The control device controls the drive frequency of a compressor on the basis of the temperature of the heat carrier flowing out from the condenser. The amount of the refrigerant sealed in the refrigerant circuit is an amount such that, with the drive frequency controlled, the first refrigerant is in a two-phase state.
