REFRIGERATION DEVICE FOR CONTAINER
Document Type and Number:
WIPO Patent Application WO/2011/064928
Kind Code:
A1
Abstract:
A refrigeration device for a container is provided with: a refrigerant circuit (20) in which a compressor (30), a condenser (31), a main expansion valve (32), and an evaporator (33) are connected in sequence, and which comprises a hot gas bypass circuit (22) for bypassing the condenser (31) and the main expansion valve (32) to convey a compressed refrigerant from the compressor (30) to the evaporator (33) and performs a refrigeration cycle; and a compressor control unit (81) which controls the operational rotation frequency of the compressor (30) such that the pressure of the compressed refrigerant from the compressor (30) reaches a target value in a defrosting operation for defrosting frost on the evaporator (33) in a circulating flow in which the compressed refrigerant from the compressor (30) returns to the compressor (30) via the hot gas bypass circuit (22) and the evaporator (33).
