Abstract

The invention provides a control method and device for an outdoor fan and an air conditioner, and relates to the technical field of air conditioners. The control method for the outdoor fan comprises the steps that an operation mode of the air conditioner is acquired; if the operation mode of the air conditioner is a refrigerating mode, the operation of the outdoor fan is controlled in the refrigerating control mode according to ambient temperature and coil pipe temperature; and if the operation mode of the air conditioner is a heating mode, the operation of the outdoor fan is controlled in a heating control mode according to the ambient temperature and the coil pipe temperature. With the control method for the outdoor fan, the operation of the outdoor fan is controlled according to the operation state of the outdoor fan matched with the operation state of the air conditioner, so that the operation state of the outdoor fan is matched with the operation state of the air conditioner, therefrigerating or heating effect of the air conditioner is guaranteed, and the energy consumption of the air conditioner is minimized.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a control method and device for an outdoor fan and an air conditioner. Background technique [0002] The function of the outdoor fan in the air conditioner is to ventilate the outdoor heat exchanger to promote heat exchange between the outdoor heat exchanger and the external environment. At present, the outdoor fan is usually operated in two or three gears based on the outdoor ambient temperature. This control method, due to the inaccurate control of the speed of the outdoor fan, leads to high energy consumption during the operation of the air conditioner. Contents of the invention [0003] The problem solved by the invention is that the control of the rotational speed of the outdoor fan is not precise enough. [0004] In order to solve the above problems, the present invention provides a control method of an outdoor fan, including: [0005] Obtain the opera...
