Abstract: An operation device (200) for remotely operating an X-ray imaging device (1) includes an operation unit (280), a grip detection unit (240), which determines whether an operation received by the operation unit (280) is a normal operation or an erroneous operation, and a control unit (230), which transmits an operation signal corresponding to the operation to the X-ray imaging device (1). The control unit (230) transmits the signal when the grip detection unit (240) determines that the operation is a normal operation. The operation device is prevented from causing an erroneous operation of its target device.

Abstract: Upon detection of a leakage of refrigerant, a refrigerant recovery operation is performed for operating a compressor in a state where an outdoor expansion valve is closed. The refrigerant suctioned from an indoor unit passes through an outdoor heat exchanger so as to be liquefied and accumulated in an outdoor unit. When a low-pressure detection value by a pressure sensor decreases below a reference value, a termination condition for the refrigerant recovery operation is satisfied, and the compressor is stopped. Furthermore, when an abnormality in the refrigerant recovery operation is detected based on a behavior of the low-pressure detection value obtained until the termination condition is satisfied, the compressor is stopped to thereby end the refrigerant recovery operation. Also, guidance information for notification about an abnormality is output to a user.

Abstract: When a refrigerant leakage sensor detects a leakage of refrigerant, a refrigerant recovery operation is started. In the refrigerant recovery operation, recovery of refrigerant in an accumulator and a pump down operation are performed in a stepwise manner. In recovery of refrigerant in the accumulator, refrigerant in a liquid phase is accumulated in the accumulator as a result of circulation of refrigerant by operating a compressor in the state where a liquid shut-off valve and a gas shut-off valve are opened. After recovery of refrigerant in the accumulator is ended, the refrigerant in a liquid phase is accumulated in an outdoor heat exchanger by the pump down operation for operating the compressor in the state where the liquid shut-off valve is closed.

Abstract: A refrigeration cycle apparatus includes a gas leakage sensor and a control device. When refrigerant leakage is detected by the gas leakage sensor, the control device performs a first mode operation to operate a compressor in such a state that a four-way valve is set to a cooling operation state, an expansion valve is opened, and a first shutoff valve is closed. After performing the first mode operation, the control device performs a second mode operation to operate the compressor in such a state that the four-way valve is set to a heating operation state and the first shutoff valve is closed.

Abstract: A refrigeration cycle apparatus capable of performing pump down operation while suppressing degradation in performance is provided. The refrigeration cycle apparatus includes an outdoor heat exchanger, a compressor including an inlet side and an outlet side, at least one indoor heat exchanger, a four-way valve, a check valve including an inlet side and an outlet side, a pipe serving as a first flow path connecting the outlet side of the check valve to the inlet side of the compressor, a first on-off valve, and a refrigerant leak detection device. The refrigeration cycle apparatus is configured such that, when a refrigerant leak is detected by the refrigerant leak detection device, pump down operation is performed as refrigerant transfer operation of transferring the refrigerant from the indoor heat exchanger to the outdoor heat exchanger.

Abstract: A space in which an indoor unit is disposed has its corresponding refrigerant leakage sensor. A remote control for the indoor unit has its corresponding information output device for notifying the user of information visually and/or aurally. When the refrigerant leakage sensor detects a leakage of refrigerant, an alarm outputs a warning sound and a safety measure device is activated. Further, the information output device outputs guidance information for notifying the user action to be taken after the safety measure device takes the safety measure. After outputting the guidance information, the information output device stops outputting the guidance information in response to completion of the user action.
