The embodiment of the invention provides a control method and device of an air duct air conditioner and the air duct air conditioner and relates to the field of air conditioners to be used for solvingthe technical problems that in the prior art, in the air duct air conditioner adopting a universal wire controller and an indoor machine without a master control board, under a heating running mode,in the period when an outdoor machine executes defrosting operation, the indoor machine can be used for blowing out cold air. According to the embodiment, in the process that the outdoor machine performs defrosting, the outdoor machine is used for sending a corresponding defrosting zone bit to the indoor machine, so that an internal circuit of the indoor machine automatically responds to the defrosting zone bit to execute the indoor machine responding operation corresponding to the defrosting zone bit, and the situation that in the air duct air conditioner adopting the universal wire controller and the indoor machine without the master control board, under the heating running mode, in the period when the outdoor machine executes defrosting operation, the indoor machine can be used for blowing out the cold air is effectively prevented. The embodiment is used for the defrosting operation process of the outdoor machine under the heating running mode of the air duct air conditioner adopting the universal wire controller and the indoor machine without the master control board.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to a control method and device for an air duct machine and the air duct machine. Background technique [0002] At present, both the indoor unit and the outdoor unit of the domestic common ducted air conditioner (ducted air conditioner, referred to as the ducted unit) are provided with a main control board. In the heating mode, when the outdoor unit starts the defrosting operation, the main control board of the outdoor unit can directly send a control signal to the main control board of the indoor unit to control the indoor unit to perform the defrosting corresponding to the defrosting operation of the outdoor unit. Response operations, such as turning off the indoor unit fan, prevent the indoor unit from blowing cold air during outdoor unit defrosting. [0003] However, in North America, the local generalized ducted units are only equipped with the main control board in the outdoor ...
