Abstract
A refrigeration cycle system includes a refrigeration cycle, a communication line, a refrigerant sensor to detect a refrigerant leak, a safety device, and a first electric wire different from the communication line. The refrigeration cycle unit includes utilization-side and heat source-side units connected by refrigerant connection pipe. The sensor is connected to the utilization-side unit. The safety device includes at least one of an alarm that makes a notification of refrigerant leak upon detection by the sensor, a ventilation device that operates upon detection of the leak, and a shutoff valve device that closes a shutoff valve on the pipe upon detection of the leak. The first electric wire is dedicated for interlock and connects between the utilization-side unit and safety device. The heat source-side unit is prohibited from operation when the utilization-side unit is not connected to the safety device via the first electric wire.
