Abstract

The invention provides a method and a device for controlling an outdoor fan of an air conditioner. The method and the device have the advantages that after a user turns on the air conditioner, the outdoor fan is started to run at a corresponding rotational speed gear selected according to the temperature of an outdoor environment under the control, the rotational speed of the outdoor fan is controlled after the fan runs for a preset period of time and is regulated and switched over according to the real-time temperature of the outdoor environment and real-time running power of an outdoor unit of the air conditioner or on the basis of real-time running frequency of a compressor, and the outdoor fan runs at a selected corresponding rotational speed gear, so that the pressure of a system constantly keeps within a relatively ideal range, a phenomenon of excessively low temperature or excessive refrigerants due to the fact that an existing outdoor fan continuously keeps carrying out intensive heat exchange while load of working space of an air conditioner is reduced can be prevented, and an energy efficiency ratio of the air conditioner can be increased; the outdoor fan does not need to constantly run at a full speed, so that the service life of the outdoor fan can be prolonged, noise generated by the outdoor unit of the integral air conditioner can be effectively reduced, and a quite and comfortable living environment can be created for the user.

Description

technical field [0001] The invention belongs to the field of refrigeration equipment control, in particular to a control method and device for an outdoor fan of an air conditioner. Background technique [0002] An air conditioner generally includes two parts: an indoor unit and an outdoor unit. The outdoor fans of air conditioners are mostly controlled by single-speed or simple two-speed control, which not only causes the outdoor fan to run at full load for a long time, affects the life of the outdoor motor, but also accelerates the fatigue and aging of the outdoor fan blades. As the user uses the air conditioner for a longer time, the load required by the air conditioner will also decrease. If the outdoor fan continues to run at a high speed, it will not only affect the energy efficiency ratio of the air conditioner, but also cause the cooling of the condenser outlet to reduce the amount of refrigerant. If it increases, it will also have a negative impact on the service li...
