A refrigeration managing apparatus that can reduce the time taken to determine refrigerant piping groups which connect refrigerant supply devices and cooling devices is provided. When determining cooling devices connected to refrigerant supply devices using refrigerant pipes, the refrigeration managing apparatus detects changes in the temperatures of evaporators of the cooling devices when the refrigerant supply devices are operated/stopped in accordance with change patterns which are stored in advance, which are determined on the basis of the number of refrigerant supply devices, and in which the states of the refrigerant supply devices are changed with time by being switched between an in-operation state and a stopped state. The refrigeration managing apparatus determines that, among the cooling devices, a cooling device having the evaporator whose temperature changes in synchronization with the in-operation/stopped state of a refrigerant supply device among the refrigerant supply devices is connected to the refrigerant supply device.
