REFRIGERATION CYCLE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a control method capable of suppressing sudden fluctuation of a discharge temperature, even in a device which uses a compressor with large heat capacity.SOLUTION: In the case where a discharge temperature Td1 detected by a compressor discharge temperature detection device is smaller than a discharge temperature determination value TdA, an opening of an electric expansion valve is adjusted so that a suction overheat degree SH detected by a suction overheat degree detection device becomes a suction overheat degree set value SHA, and in the case where the discharge temperature is larger than the discharge temperature determination value TdA, the opening of the electric expansion valve is adjusted according to a change amount (Td1-Td0) between the suction overheat degree SH and the discharge temperature.SELECTED DRAWING: Figure 3
