The invention discloses a control method of an air pipe machine and the air pipe machine, and belongs to the field of air conditioner indoor units and control methods thereof. The control method of the air pipe machine and the air pipe machine are designed to solve the problem that an existing device draught fan is low in efficiency. The control method of the air pipe machine comprises the steps that corresponding draught fans of a heat exchanger are divided into at least two areas, and the rotating speed of the draught fans is controlled according to the actual temperature values of all the areas. The air pipe machine comprises the heat exchanger and at least two draught fans connected in parallel. A temperature induction device is arranged between the heat exchanger and each draught fan, and is in signal connection to a control device. Each draught fan is provided with an independent drive device. According to the control method of the air pipe machine, the efficiency of the draught fans is maximized, the heat exchange efficiency is improved, and the system reliability is improved. The control method can be achieved through the air pipe machine, the efficiency and heat exchange efficiency of the draught fans are improved, and the system reliability is improved.
Description
technical field [0001] The invention relates to the field of an air conditioner indoor unit and a control method thereof, in particular to a control method of an air duct unit and an air duct unit for realizing the control method. Background technique [0002] The air duct machine is a common air conditioner indoor unit. In order to solve the problem that the air duct machine or hot air cannot reach the bottom of the room due to the different specific gravity of cold air and hot air, or that the cold air blows directly and makes the user feel too cold, a two-way air outlet type air duct machine has appeared. The direction of the wind in the two-way air duct machine can be changed, and the air is sent from the side when cooling, and the air is sent from the bottom when heating, which improves the comfort of the air duct machine. [0003] There is an existing two-way air outlet type air duct machine with a plurality of axial flow fans arranged in parallel, and the two-way win...
