Kind Code:
A
Abstract:
To provide a new hypercomplex refrigeration device.SOLUTION: A refrigeration device comprises: a user side heat transfer cycle which has a user side compressor, a user side heat exchanger, a user side decompressor and a user side cascade heat exchanger and circulates a user side coolant; a heat source side heat transfer cycle which has a heat source side compressor, a heat source side heat exchanger, a heat source side decompressor and a heat source side cascade heat exchanger and circulates a heat source side coolant; a cascade heat exchanger which performs heat exchange between the user side coolant in a user side condenser and the heat source side coolant in a heat source side evaporator; and a control device. The user side coolant has a boiling point of -30°C or higher and 25°C or lower. The heat source side coolant has a boiling point of -55°C or higher and less than -30°C.SELECTED DRAWING: None
