Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/063838
Kind Code:
A1
Abstract:
This refrigeration cycle device has a heat-source unit, a cooling unit, a first connecting tube, and a second connecting tube. The heat-source unit has a compressor for compressing coolant, a high-pressure-side heat exchanger for cooling the coolant from the compressor, and a principal depressurization device for depressurizing the coolant from the condenser. The cooling unit has a low-pressure-side heat exchanger for vaporizing the coolant. The first connecting tube guides the coolant conveyed from the principal depressurization device to the low-pressure-side heat exchanger to the interval between the heat-source unit and the cooling unit. The second connecting tube guides the coolant conveyed from the low-pressure-side heat exchanger to the compressor to the interval between the heat-source unit and the cooling unit. The first connecting tube creates a coolant pressure loss in a range in which the saturation temperature of the coolant in the low-pressure-side heat exchanger does not fall below the use vaporization temperature of the low-pressure-side heat exchanger.
