Abstract (en)
[origin: EP4027076A1] A refrigeration cycle device with excellent safety that can prevent water in a water heat exchanger from freezing.A water heat exchange unit includes a water heat exchanger, a pump for circulating water between a water flow path of the water heat exchanger and a load, and a water heat controller, and is operated by a power source different from that of the outdoor unit and the indoor unit. The water heat exchanger controller operates the pump when the temperature of the water heat exchanger is below a set value. An outdoor controller of the outdoor unit permits operation of the refrigeration cycle device when the number of operable water heat exchange units reaches a specified number of units, and prohibits operation of the refrigeration cycle device when the number of operable units does not reach the specified number of units.
