Title:
CARBON DIOXIDE ABSORPTION/DISCHARGE DEVICE, AND HEAT PUMP SYSTEM USING THE DEVICE
Document Type and Number:
Japanese Patent JP2019181401
Kind Code:
A
Abstract:
To provide a carbon dioxide absorption/discharge device capable of saving energy, and to provide a heat pump system using the device.SOLUTION: A heat pump system 10 comprises: an absorption type heat pump circuit 30 having an absorption circuit 40 comprising an absorption part contacting an amine-including absorbent with carbon dioxide under the conditions of a pressure P1 and temperature T1 to absorb the gas, a discharge part discharging carbon dioxide from a rich absorbent under the conditions of the pressure P2 higher than P1 and the temperature T2 higher than T1, and a recovery part separating carbon dioxide from the absorbent; and a compression type heat pump circuit 20 utilizing the shaft output of a motor as the power source of a compressor compressing a coolant. Thus, the system is configured to supply the coolant regenerated by a regenerator to the suction port of the compressor and to circulate the coolant heat-exchanged in a utilization side heat exchanger to the absorber of the absorption circuit 40.SELECTED DRAWING: Figure 1
