Abstract: A control apparatus is configured for adjusting a control value for a refrigerating machine of a cooling system and performing control of the cooling system in conformity with an environmental condition. A controller has a data base having environmental condition cells in which control values for the refrigerating machine are respectively registered in association with respective environmental conditions.

Abstract: 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.

Abstract: A technology for achieving energy saving by efficiently controlling each of a plurality of equipment systems is proposed. The equipment control system includes an air conditioner system, a refrigerator system, a refrigerator/freezer showcase system and a central coordinator. Status data related to electric equipment provided in the systems is transmitted to the central coordinator. The central coordinator computes control data for the systems, based on the status data of the electric equipment transmitted. The central coordinator is provided with the function of computing the control data, based only on the status data of the corresponding electric equipment and the function of computing the control data, allowing for the status data of another of electric equipment in addition to the status data of the corresponding electric equipment.
