摘要： An air-conditioning apparatus in which a primary-side refrigerant in a two-phase gas-liquid state that has flowed into each of intermediate heat exchangers absorbs heat from a secondary-side refrigerant flowing in counterflow to the primary-side refrigerant, and evaporates and turns into a low-temperature, low-pressure gas state. The air-conditioning apparatus ensures high heat exchange efficiency even when a direction of a heat source-side refrigerant (secondary-side refrigerant) flowing through an intermediate heat exchanger changes, and enables an appropriate operation in any operation mode.

摘要： A first cycle, in which a first medium is circulated, employs a compressor, a first heat exchanger structured with an air heat exchanger, a second heat exchanger, and a third heat exchanger. A second cycle, in which a second medium is circulated and heat is exchanged with the first medium through the second heat exchanger, employs indoor units, each having a fan. A third cycle, in which the second medium is circulated and heat is exchanged with the first medium through the third heat exchanger, shares the indoor units with the second cycle. Flow path switching valves switch flow paths between the second cycle and third cycle. Before the first heat exchanger is defrosted, a halted indoor unit is filled with the second medium in the third cycle with its fan being halted. The third heat exchanger functions as an evaporator during a defrosting operation.
