{Abstract} In a refrigeration / air-conditioning device including a refrigeration cycle (29), and an expansion valve control means (35), the expansion valve control means (35) includes 5 a target value switching means (36) which adopts the lower one of a target degree of discharge superheat TdSH plus a high pressure saturation temperature and an upper-limit value of the discharge temperature Td as a target value, or compares a target discharge temperature Td obtained from 10 calculation of the number of rotations of a compressor and the high pressure saturation temperature with an upper limit value and adopts the lower one of the target discharge temperature Td and the upper-limit value as the target discharge temperature Td while performing the 15 control at the predetermined degree of discharge superheat TdSH or the control at the predetermined discharge temperature Td.
