Document Type and Number:
Japanese Patent JP2021196115
Kind Code:
A
Abstract:
To provide a refrigeration machine for transportation that has further improved efficiency.SOLUTION: A refrigeration machine for transportation comprises an indoor heat exchanger for exchanging heat between air in a refrigerating chamber and a first refrigerant, a first compressor for compressing and supplying the first refrigerant to the indoor heat exchanger, a first inverter for driving the first compressor, an outdoor heat exchanger for exchanging heat between outside air and a second refrigerant, a second compressor for compressing and supplying the second refrigerant to the outdoor heat exchanger, a second inverter for driving the second compressor, an intermediate heat exchanger for exchanging heat between the first refrigerant flowing from the first compressor and the second refrigerant flowing from the outdoor heat exchanger, and a control unit for sending a driving signal to the first inverter and the second inverter on the basis of a temperature difference between the inside of the refrigerating chamber and the outside air.SELECTED DRAWING: Figure 2
