摘要： A control method for an air conditioner includes: determining the frosting state of an indoor unit when an air conditioner is operated in a refrigeration mode (S301); and controlling to block a refrigerant pipeline flowing to the indoor unit (S302) when the indoor unit frosts in the refrigeration mode. According to the control method, by controlling to block the refrigerant pipeline flowing to a heat exchanger which frosts, continuous input of a low-temperature refrigerant to the frosted heat exchanger can be stopped, so as to avoid further aggravation of the frosting problem. Moreover, the heat exchanger can be naturally defrosted and deiced by means of the temperature of an environment of the heat exchanger, so as to achieve the freezing protection effect for the heat exchanger of the air conditioner. A control device for an air conditioner is further disclosed.

摘要： A method employing an air conditioner (1) for reporting a fire, and an air conditioner (1). The method comprises: detecting a smoke concentration in a space where an indoor unit (11) of the air conditioner (1) is located; and when a second setting condition or a first setting condition is satisfied, the air conditioner (1) activating a second mode to provide a fire report notification or activating a first mode to provide an alert. The air conditioner (1) comprises an indoor unit (11) provided with a smoke detector (111) and a microprocessor (12). The microprocessor (12) comprises an information receiving and transmitting unit (121) and an information processing unit (122). The information receiving and transmitting unit (121) is used to receive or transmit information. The received information comprises information about a smoke concentration detected by the smoke detector (111). The transmitted information comprises alarm information and fire reporting notification information. The information processing unit (122) is used to activate a second mode to provide a fire report notification or to activate a first mode to provide an alert when a second setting condition or a first setting condition is satisfied.
