摘要： An air conditioning device (1) in which an indoor unit (2a, 2b) and an outdoor unit (3) are connected by refrigerant pipes (4a, 4b) circulating a refrigerant therethrough, said air conditioning device (1) being provided with: a refrigerant detection unit (9) that detects leakage of the refrigerant in the indoor unit; notification units (10, 11, 20) for providing notification that leakage of the refrigerant has occurred; a communication unit (15) capable of communicating with an external terminal device over a network; and a control unit (13) that controls at least the notification units and the communication unit. The notification units include, in addition to a display unit of a remote controller for operating the indoor unit, a display unit (10) and/or a speaker (11) disposed on the surface of the housing of the indoor unit, and the external terminal device (20). The control unit controls the notification units and the communication unit to provide notification that leakage of the refrigerant has occurred if leakage of the refrigerant is detected by the refrigerant detection unit. By providing notification of a warning regarding leakage of the refrigerant not only to the notification unit disposed on the indoor unit but also to the external terminal device in this manner, the attentiveness of a user who is not near the indoor unit to the notification is improved, making it easier for the user to notice the notification and to be aware that leakage of the refrigerant has occurred.

摘要： In einem Klimagerät sind eine Inneneinheit und eine Außeneinheit über eine Kältemittelleitung, durch die Kältemittel fließt, miteinander verbunden. Das Klimagerät weist auf: eine Kältemittel-Erfassungseinheit, die ein Austreten von Kältemittel in der Inneneinheit erfasst; eine Benachrichtigungseinheit, die eine Benachrichtigung ausgibt, die das Auftreten des Austretens von Kältemittel angibt; eine Steuerung, die wenigstens die Benachrichtigungseinheit steuert; und eine Fernbedienungseinheit, die dazu ausgebildet ist, die Inneneinheit zu bedienen. Wenn die Kältemittel-Detektionseinheit das Austreten von Kältemittel detektiert, steuert die Steuerung die Benachrichtigungseinheit, um die Benachrichtigung, die das Auftreten des Austretens von Kältemittel angibt, auf eine erste Weise vorzunehmen, und um die Benachrichtigung auf eine zweite Weise vorzunehmen, die sich von der ersten Weise unterscheidet, nachdem eine vorbestimmte Zeitspanne ab dem Zeitpunkt verstrichen ist, zu dem die Benachrichtigung auf die erste Weise vorgenommen worden ist. Da die Benachrichtigung über das Austreten von Kältemittel in zwei Schritten erfolgt, d. h. in einem ersten Schritt auf die erste Weise und in einem zweiten Schritt auf die zweite Weise, ist es möglich, einen Benutzer dazu zu veranlassen, den Benachrichtigungen mehr Aufmerksamkeit zu schenken, und somit den Benutzer dazu zu veranlassen, die Benachrichtigung leicht zu bemerken. Es ist daher möglich, dem Benutzer ausreichend Kenntnis von dem Austreten von Kältemittel zu verschaffen.

摘要： This air conditioner is provided with: a housing; a gas sensor that is disposed in the housing and outputs a sensor output in accordance with the concentration of a refrigerant; a control device that compares the sensor output of the gas sensor with a first threshold value that is a threshold value for determining the presence or absence of refrigerant leakage so as to detect the refrigerant leakage; and an output device that issues a warning. The control device causes the output device to issue a warning in a case where a state, in which the sensor output of the gas sensor is not less than a second threshold value, which is set as a voltage lower than a limit voltage and which indicates that sensitivity of the gas sensor is zero due to siloxane poisoning, and is less than the first threshold value higher than the second threshold value, is continued for a predetermined setting period.

摘要： In this refrigeration cycle apparatus, a control unit is configured so as to execute a first running mode and a second running mode, which are running modes for an air-blowing fan. In the first running mode, running of the air-blowing fan is started on the basis of a first operation performed via an operation unit, and the air-blowing fan is stopped on the basis of a second operation performed via the operation unit. In the second running mode, running of the air-blowing fan is started if refrigerant is detected by a refrigerant detection means, the air-blowing fan is not stopped on the basis of the second operation but is stopped on the basis of a third operation different from the second operation, and running of the air-blowing fan is restarted on the basis of a fourth operation different from the first operation.

摘要： An air conditioning device in which an indoor unit and an outdoor unit are connected via refrigerant piping through which refrigerant flows comprises a refrigerant detection unit that detects refrigerant leaks in the indoor unit, a notification unit for giving notification that a refrigerant leak has occurred, a control unit that controls at least the notification unit, and a remote control for operating the indoor unit. The control unit controls the notification unit so as to give notification in a first manner that a refrigerant leak has occurred if a refrigerant leak is detected by the refrigerant detection unit and to give notification in a second manner, which is different from the first manner, after a fixed time passes from the notification in the first manner. Thus, by giving notifications pertaining to refrigerant leaks in two steps in the first manner and the second manner, a user can easily be made to notice and attend to the notification and the refrigerant leak can be made well known.
