Embodiment Construction

[0038] In the current technology, the outdoor fan of the air-conditioning system usually has multiple windshields, so the adjustment of the speed of the outdoor fan can only be switched between several fixed windshields, and the flexibility is poor. And the current related technology does not take the outdoor temperature into the reference factor to adjust the speed of the external fan, so the speed of the external fan cannot match the load demand of the air conditioning system well, and there will be insufficient or excessive speed to consume energy heightened problem.

[0039] Therefore, embodiments of the present application provide a method for controlling an outdoor fan and an air-conditioning system. The target speed of the outdoor fan is calculated according to the outdoor temperature, and the speed of the outdoor fan is adjusted according to the target speed, wherein the outdoor temperature is linearly correlated with the target speed. In this way, the speed of the out...

Abstract

The embodiment of the invention provides an external fan control method and an air conditioning system, and relates to the technical field of air conditioners. According to the external fan control method, a target rotating speed is calculated according to reference factors comprising outdoor temperature, then an external fan is controlled to be adjusted according to the target rotating speed, due to the fact that the target rotating speed and the outdoor temperature are in the linear relation, the rotating speed of the external fan can be linearly adjusted, compared with existing multi-gear adjustment, the adjustment is more flexible, and the load requirement of an air conditioner can be better met. The air conditioning system can realize the external fan control method, so that the air conditioning system also has the beneficial effects.

Description

technical field [0001] The present application relates to the technical field of air conditioning, and in particular, relates to an external fan control method and an air conditioning system. Background technique [0002] The external fan is an important part of the air conditioning system. The speed of the external fan directly affects the air volume of the heat exchanger, can adjust the operating parameters of the air conditioning system, and plays a key role in the stable operation of the air conditioner. [0003] At present, the control of the speed of the outdoor fan mostly adopts the method of dividing levels, that is, the external fan is divided into different wind gears, corresponding to different speeds. After the air conditioner is turned on, the outdoor fan can only run according to the preset fixed speed or between adjacent wind gears. Switching, so the control of the external fan is not flexible enough. In this way, it is easy to cause a mismatch between the sp...
