Title:
TURBO REFRIGERATOR, REFRIGERATOR CONTROL DEVICE, TURBO REFRIGERATOR CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/057556
Kind Code:
A1
Abstract:
This turbo refrigerator comprises: a turbo compressor that compresses a refrigerant gas; a vane that is capable of adjusting the flow rate of the refrigerant gas sucked in by the turbo compressor; a condenser that causes, by means of heat exchange, the refrigerant gas compressed by the turbo compressor to release heat and therefore become condensed; an expansion valve that expands a liquid refrigerant guided from the condenser; an evaporator that causes, by means of heat exchange, the liquid refrigerant expanded by the expansion valve to absorb heat and therefore evaporate; and a refrigerator control device. The refrigerator control device comprises: an acquisition unit that acquires at least a state quantity of the refrigerant gas during startup of the turbo refrigerator; an opening degree determination unit that determines the opening degree of the vane on the basis of the acquired state quantity; and an opening degree control unit that controls the opening degree of the vane on the basis of the determined opening degree.
