PROBLEM TO BE SOLVED: To provide a control method capable of suppressing sudden fluctuation of a discharge temperature, even in a device which switches the control method of a throttle device and a device which uses a compressor with large heat capacity.SOLUTION: In a refrigeration cycle device, an opening of an electric expansion valve 6 is adjusted so that a discharge temperature Td detected by a compressor discharge temperature detection device 15 becomes a target discharge temperature set value TdX. In the case where the discharge temperature Td exceeds a discharge temperature determination value TdA, the opening of the electric expansion valve 6 is adjusted so that the discharge temperature Td becomes a discharge temperature set value Td1. The discharge temperature set value Td1 is changed according to the discharge temperature Td and the target discharge temperature set value TdX based on the discharge temperature Td when it has exceeded the discharge temperature determination value TdA.SELECTED DRAWING: Figure 7 |
