Abstract:
An air conditioning apparatus comprising: a heat-source-side device including an intermediate heat exchanger that exchanges heat between a heat-source-side heating medium and a user-side heating medium different from the heat-source-side heating medium, and performs switching so as to cause the heat-source-side heating medium to absorb or release heat and cause the user-side heating medium to change phase; and a user-side cycle circuit that circulates the user-side heating medium via a pipe connection of the intermediate heat exchanger, a user-side heat exchanger for heating or cooling air in an air-conditioned space through a heat exchange involving a pump for suctioning and feeding the liquid user-side heating medium and a phase change of the user-side heating medium, and a decompression device for decompressing the user-side heating medium passing through the user-side heat exchanger.
