Problems solved by technology

In related technologies, when the control system of the conventional split-type inverter air conditioner is in a low-temperature cooling state, the gear distribution of the outdoor fan is not reasonable enough. For example, when the outdoor ambient temperature is not particularly low, if the outdoor fan is at a low speed, The temperature of the outlet pipe of the condenser will be relatively high (such as 10-15 degrees), which will

Abstract

The invention discloses a method and device for controlling an outdoor fan in a split air-conditioner. The method includes the steps that the current outdoor environment temperature is detected; when the current outdoor environment temperature is larger than or equal to a preset outdoor environment temperature threshold value, the gear mode of the outdoor fan is determined according to the current outdoor environment temperature; when the current outdoor environment temperature is smaller than the preset outdoor environment temperature threshold value, the current outdoor condenser outlet pipe temperature is detected, and the current operation frequency of a compressor is acquired; the gear mode of the outdoor fan is determined according to the current outdoor environment temperature, the current outdoor condenser outlet pipe temperature and the current operation frequency of the compressor. According to the method, linkage control can be conducted according to the four parameters of the outdoor environment temperature, the condenser outlet pipe temperature, the revolving speed of the outdoor fan and the operation frequency of the compressor, the air-conditioner can operate efficiently, and therefore the low temperature refrigeration capacity is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method and device for controlling an outdoor fan in a split air conditioner. Background technique [0002] At present, the low-temperature refrigeration function of the air-conditioning system has been widely used at home and abroad, such as the use in the computer room. In related technologies, when the control system of the conventional split-type inverter air conditioner is in a low-temperature cooling state, the gear distribution of the outdoor fan is not reasonable enough. For example, when the outdoor ambient temperature is not particularly low, if the outdoor fan is at a low speed, The temperature of the outlet pipe of the condenser will be relatively high (such as 10-15 degrees), which will easily cause high-temperature protection of the condenser and unnecessary shutdown of the compressor; on the contrary, when the outdoor ambient temperature is relatively low...
