Claim Text:
1. An air conditioning apparatus comprising: a refrigerant circuit including a compressor, a four-way switching valve, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger interconnected with each other, the refrigerant circuit being configured to switch the outdoor heat exchanger using multi-hole flat tubes as heat transfer tubes, when stopping the heating operation, the air conditioning apparatus performs pressure equalization control that switches the four-way switching valve from the heating cycle state to the cooling cycle state, and thereafter stops the compressor, and equalizes pressure in the refrigerant circuit, and a first opening degree of the expansion valve after the four-way switching valve is switched from the heating cycle state to the cooling cycle state being greater than a second opening degree of the expansion valve when the four-way switching valve is switched from the heating cycle state to the cooling cycle state.
