Title:
FREEZING CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/085557
Kind Code:
A1
Abstract:
A freezing cycle device includes a freezing cycle formed by successively connecting a compressor (1), a radiator (2), an expansion device (3), and an evaporator (4) in series, and a bypass circuit (6) for bypassing the expansion device (3), an open/close valve (7) arranged on the bypass circuit (6), and a controller (C1) for controlling the open degree of the open/close valve (7). The open/close valve (7) is controlled by the controller (C1) so that a coolant passes through the bypass circuit (6) during defrost operation, thereby preventing lowering of the coolant flow amount during defrost operation and reducing the defrost operation time.
