Control method, device and air conditioner for an air conditioning system

Abstract

The invention provides a control method and device for an air conditioner system and an air conditioner. The control method for the air conditioner system comprises the steps of detecting the outdoorenvironment temperature, the outdoor condenser outlet refrigerant pressure and the outdoor condenser outlet pipeline temperature in real time; controlling a fan to operate in the first preset time ata preset gear; according to the outdoor condenser outlet refrigerant pressure, obtaining the corresponding saturation temperature, and calculating the refrigerant coefficient; according to the presetsection where the refrigerant coefficient is located, controlling the operation gear of the fan and the opening of a throttling device, wherein when the preset gear is the initial gear corresponding to the outdoor environment temperature when the air conditioner system is started. According to the preset section where the refrigerant coefficient is located, the operation gear of the fan and the opening of the throttling device are reasonably optimized, by controlling the opening of the throttling device, the air conditioner system is made to be in the best refrigerant circulation amount all the time, and by adjusting the operation gear of the fan, the fan is operated in the best state all the time; accordingly, the heat exchange efficiency and reliability of the unit are improved.

Description

technical field [0001] The present invention relates to the technical field of control of air conditioning systems, and in particular, to a control method, device and air conditioner of an air conditioning system. Background technique [0002] With the improvement of people's living standards, air conditioners have entered the vast majority of ordinary families and have been used more and more widely. However, in recent years, due to energy shortages and the requirements of national policies, people have more and more energy-saving requirements for air-conditioning systems. higher. The fan operation mode of the existing air-conditioning system cannot be adjusted according to the operating characteristics of the unit, and the air-conditioning system cannot be in a high-efficiency operation state at all times, resulting in the heat transfer efficiency of the heat exchanger not being effectively utilized, thereby affecting the actual operation effect of the unit. , unable to m...

AI Technical Summary

Problems solved by technology

The fan operation mode of the existing air-conditioning system cannot be adjusted according to the operating characteristics of the unit, and the air-conditioning system cannot be kept in a state of high-efficiency operation at all times, resulting in the ineffective use of the heat transfer efficiency of the heat exchanger, which in turn affects the actual operating effect of the unit , unable to meet the dual needs of energy development and market development, high-efficiency heat transfer technology needs to be further developed and utilized
