Outdoor unit for water heater

Distribution controller for air conditioner

Chiller unit

An air-conditioning device includes a refrigerant circuit including a compressor, a heat source-side heat exchanger, an expansion unit, and an intermediate heat exchanger connected by a refrigerant pipe, through which refrigerant circulates; and a heat medium circuit including a pump, the intermediate heat exchanger, and a load-side heat exchanger connected by a heat medium pipe, through which heat medium circulates. A discharge unit connected downstream of the intermediate heat exchanger in the heat medium circuit discharges fluid flowing through the heat medium pipe, depending on pressure of the fluid. A refrigerant concentration detector detects concentration of the refrigerant contained in the fluid discharged from the discharge unit. A notification device notifies leakage of the refrigerant. A controller activates the notification device depending on the concentration of the refrigerant detected.
