An air conditioning equipment is provided wherein reduction in size of an outdoor heat exchanger, improvement of reliability, and low cost can be achieved without reduction in system efficiency. In the air conditioning equipment, the same working medium is employed in Rankine cycle (first cycle) and refrigerant cycle (second cycle) and an expander and a compressor used in respective cycles are installed in the same enclosure.

[ What is claimed is:] [1.] An air conditioning equipment comprising:a refrigerant heater for heating a refrigerant;an expander for expanding said refrigerant output from said refrigerant heater to generate a driving force;an outdoor heat exchanger for cooling said refrigerant output from said expander;a pump for feeding said refrigerant output from said outdoor heat exchanger to said refrigerant heater, whereby said refrigerant heater, said expander, said outdoor heat exchanger, and said pump constitute a first cycle;a compressor operated by said driving force derived from said expander in cooling operation mode, for compressing a refrigerant;an outdoor heat exchanger for cooling said refrigerant discharged from said compressor;an expansion valve for expanding said refrigerant output from said outdoor heat exchanger; andan indoor heat exchanger for receiving said refrigerant whose temperature is lowered by said expansion valve, whereby said compressor, said outdoor heat exchanger, said expansion valve, and said indoor heat exchanger constitute a second cycle;wherein said refrigerant circulated in said first cycle and said refrigerant circulated in said second cycle are identical in composition, and said compressor and said expander are incorporated into a same sealing case.
