A setting facilitation apparatus () includes a keyword input reception section (), a control command selection section (), and a specific control registration section () and is used to facilitate setting of specific control in a control system () that controls a control device through sound inputs. The keyword input reception section () receives an input of information corresponding to a keyword. The control command selection section () displays a certain control command to the control device () on an edit screen (G) and receives selection of the control command. The specific control registration section () registers a keyword (K) input by the keyword input reception section () and the control command selected by the control command selection section () to a specific control (DBT) while associating the keyword and the control command with each other.

Device control system

An air conditioning system suppresses energy consumption by efficient shared use of air in a common space that is not subjected to air conditioning in an indoor area, among a plurality of air conditioners for the purpose of heat exchange. A plurality of air conditioners each include: a usage-side heat exchanger configured to carry out heat exchange with air in an air-conditioning target space; a heat source-side heat exchanger configured to carry out heat transfer to and from the usage-side heat exchanger; and a heat source-side fan configured to feed air from a common space to the heat source-side heat exchanger and to blow the air into the common space. The heat source-side heat exchangers of the air conditioners are disposed in the common space. A first ventilation fan whose airflow volume is changeable is disposed near an exhaust port through which air is discharged from the common space toward an outdoor area. A controller changes the airflow volume of the ventilation fan, based on information on an air temperature of the common space.

Air conditioning system

An air conditioner which continues driving with a deteriorated gas leakage sensor is provided. An air conditioner of the present invention includes an outdoor unit including a compressor and an indoor unit connected with the outdoor unit and uses flammable refrigerant. The air conditioner includes: a refrigerant gas sensor; and a controlling unit configured to stop the compressor at occurrence of abnormality, when the refrigerant gas sensor detects refrigerant gas while the compressor is being driven. After the compressor is stopped as the refrigerant gas sensor detects the refrigerant gas, the controlling unit does not start driving of the compressor until an operation to cancel the abnormality is performed.

Air conditioner

In an air conditioning system which conditions air in one air-conditioning-target space with a plurality of air conditioners each including a compressor, the energy consumption efficiency as a whole is improved. The air conditioners (to) each include a service-side heat exchanger exchanging heat between air of a room which is the air-conditioning-target space and a refrigerant, a heat-source-side heat exchanger exchanging heat between air of a common space and the refrigerant, and a compressor (to) compressing the refrigerant circulating through the service-side heat exchanger and the heat-source-side heat exchanger. When an air conditioning capacity falls within a predetermined range for at least two of the plurality of air conditioners (to), part of the air conditioners whose compressors are in operation has its compressor stopped.

When a service technician or the like performs maintenance of a mechanism in an indoor unit, the service technician may accidentally detach a refrigerant gas sensor and the refrigerant gas sensor may be broken. To prevent this, communication pipes (regulating members) configured to regulate the detachment of a refrigerant gas sensor are provided on the side toward which the refrigerant gas sensor is detached (front side) when a casing provided on the side toward which the refrigerant gas sensor is detached (front side) is open.

Air-conditioner indoor unit

An air conditioner which is able to prevent leaked refrigerant gas from disadvantageously stagnating at a part of a room space when leakage of refrigerant gas occurs in an indoor unit is provided. An air conditioner of the present invention includes an indoor unit having an upper outlet port and a lower outlet port and uses flammable refrigerant, the air conditioner including: a shutter provided at the lower outlet port and is configured to switch between a blowout capable state in which wind is blown out and a blowout incapable state in which no wind is blown out; a refrigerant gas sensor provided in the indoor unit, and a controlling unit configured to control the shutter. In a driving state in which the lower outlet port is in the blowout incapable state, when the refrigerant gas sensor detects the refrigerant gas, the controlling unit switches the lower outlet port from the blowout incapable state to the blowout capable state.
