Abrégé

This refrigeration cycle device has an indoor unit, a first outdoor unit, a second outdoor unit, and a control unit. The indoor unit has an indoor heat exchanger. The first outdoor unit and the second outdoor unit are connected in parallel with the indoor unit. The second outdoor unit has a compressor, an outdoor heat exchanger, and a four-way valve. The four-way valve switches between supplying the refrigerant discharged from the compressor to the indoor heat exchanger and the outdoor heat exchangers. The four-way valve has a main valve having a main valve body, and an auxiliary valve having an auxiliary valve body. The main valve body can move between a first position and a second position. In the first position, the refrigerant discharged from the compressor is supplied to one of the indoor heat exchanger and the outdoor heat exchangers. In the second position, the refrigerant discharged from the compressor is supplied to the other of the indoor heat exchanger and the outdoor heat exchangers. The auxiliary valve body is driven by a solenoid and can move between a third position and a fourth position. In the third position, the main valve body is arranged in the first position. In the fourth position, the main valve body is arranged in the second position. In the case that the first outdoor unit is operated and the second outdoor unit is stopped, if the main valve body is not in the first position, then, after the auxiliary valve body has been arranged in the fourth position, the control unit moves the auxiliary valve body to the third position.

Abrégé

An equipment-management device associated with at least one of multiple pieces of equipment in a building under management, the equipment-management device including a display-information generator, a touchscreen, and an action-control-information generator. The display-information generator generates display information on a management screen wherein icons are arranged, each of the icons including an outer frame and a first area set at one end along the major axis within the outer frame. The touchscreen displays the display information and receives an input of information relating to an operation performed on the management screen. Upon detecting that a slide operation performed on one of the icons of the management screen from the first area through a first slide-operation detecting line set inside the outer frame excluding the first area, the action-control-information generator generates action-control information that switches the power supply of the corresponding equipment on or off.
