Embodiment Construction

[0052] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0053] The structure of the air side of the existing split-type air conditioner outdoor unit has the following problems: the heat exchanger is rectangular, while the fan is circular, resulting in a mismatch between the two areas, and the aerodynamic performance is reduced; the airflow passes through the heat exchanger with dense fins. After the heater enters the fan, the air flow on the inlet section of the fan is in a complex state. For a system working under this condition, the distribution of the flow field will directly affect the heat transfer and aerodynamic performance of the air conditioner.

[0054]When the outdoor unit of the air conditioner is under frosting conditions in winter, the resistance of air flowing through the fins of ...

Abstract

The invention provides an adaptive control method, device, air conditioner and storage medium for a fan when frosting occurs, and relates to the technical field of air conditioners, including acquiring outdoor ambient temperature and outdoor ambient humidity; if the outdoor ambient temperature and the outdoor ambient temperature If the ambient humidity meets the first condition, the fan is controlled to adjust the speed according to the fan current; otherwise, the fan is controlled to adjust the speed according to the low-pressure temperature of the fan module. The invention selects different control parameters according to the outdoor environment temperature and the outdoor environment humidity to adjust the fan speed, avoids the overcurrent protection of the fan module, and improves the reliability of the system. In addition, the motor will not run under high load for a long time, which can effectively improve the service life of the motor. The invention can automatically control the fan to reduce the rotating speed, so that the whole machine is always in the running state, thereby ensuring the constant indoor temperature and improving user experience.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, and in particular, relates to an adaptive control method, device, air conditioner and storage medium for a fan when frosting occurs. Background technique [0002] With the development of social economy and the improvement of people's living standards, air conditioners have entered thousands of households and become a necessity of modern life, creating a comfortable working and living environment for users. Nowadays, people not only use air conditioners for refrigeration, but also use air conditioners for heating in winter more and more frequently, so the requirements for the stability of air conditioners in winter heating operation are also getting higher and higher. [0003] At present, when the air conditioner is heating in winter, the outdoor unit is prone to frost in cold temperatures. In the case of a thick frost layer, the resistance of air flowing through the finned tubes...
