IPC: F25B1/00
Filed: 2009-02-24
Abstract: <P>PROBLEM TO BE SOLVED: To stably operate an ejector type refrigeration cycle even with a change in the flow rate of a driving flow that passes through a nozzle of an ejector.  <P>SOLUTION: A second compression mechanism 21a is provided for sucking and compressing a refrigerant flowing out of a utilization side heat exchanger 51 functioning as an evaporator and discharging the refrigerant to the refrigerant suction port 13b side of the ejector 13 in a cooling operation mode while sucking and compressing a refrigerant discharged from a first compression mechanism 11a and discharging the refrigerant to the utilization side heat exchanger 51 side in a heating operation mode. Consequently, even under such operating conditions that the suction capacity of the ejector 13 is degraded accompanied by a fall in the flow rate of driving flow of the ejector 13 in the cooling operation mode, the suction capacity of the ejector 13 is assisted by the second compression mechanism 21a, and a refrigeration cycle can be constituted without using the ejector 13 as a refrigerant pressure reducing means in the heating operation mode. The cycle can thereby be stably operated in any operation mode.  <P>COPYRIGHT: (C)2010,JPO&INPIT
