Title:
CHILLING MACHINE
Document Type and Number:
WIPO Patent Application WO/2015/137000
Kind Code:
A1
Abstract:
A chilling machine comprising: a refrigerant circuit in which a refrigerant circulates; a compressor, a condenser, a first expander, a heat generator, and an accumulator that are provided in the refrigerant circuit; a coolant circuit including a first supply destination and a second supply destination, to which the coolant is supplied at different temperatures; and a cooler that cools the coolant, has the heat generator arranged therein, and is provided in the coolant circuit. The coolant circuit has a first supply path which supplies low-temperature coolant to the first supply destination and a second supply path which supplies high-temperature coolant to the second supply destination. The refrigerant circuit has: a first reheater that increases the temperature of the coolant supplied through the second supply path, by using heat from the refrigerant discharged from the compressor; a first selection path that bypasses the first reheater and supplies the refrigerant discharged from the compressor to the condenser; a second selection path that supplies the refrigerant discharged from the compressor, to the condenser via the first reheater; and a control unit that regulates the amount of refrigerant that flows through the first selection path and the amount of refrigerant that flows through the second selection path.
