Title:
REFRIGERATION APPARATUS, AND METHOD OF OPERATING REFRIGERATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/022076
Kind Code:
A1
Abstract:
A refrigeration apparatus is provided with a heat source unit (1), a cooling unit (2), a low-pressure-gas pipe (5), and a bypass circuit (BC). Accommodated in the heat source unit (1) is a compressor (7), a condenser (8), and a pipe (1a). The compressor (7) has variable capacity, and compresses and discharges refrigerant that has been suctioned thereinto. The condenser (8) condenses the refrigerant compressed by the compressor (7). The pipe (1a) connects the compressor (7) and the condenser (8). Accommodated in the cooling unit (2) is an expansion valve (13) and a cooling device (14). The expansion valve (13) reduces the pressure of the refrigerant condensed by the condenser (8). The cooling device (14) vaporizes the refrigerant of which the pressure was reduced by the expansion valve (13). The low-pressure-gas pipe (5) connects the cooling device (14) and the compressor (7). The bypass circuit (BC) connects the pipe (1a) disposed inside the heat source unit (1) and the low-pressure-gas pipe (5) disposed inside the cooling unit (2).
