Control method and related equipment of outdoor fan in multi-connected system

Abstract

The invention relates to a control method of a multi-split system outdoor fan and related equipment. The method comprises the steps of obtaining running information of a multi-split system; accordingto the running information, calculating system actual running high pressure value; according to the system actual running high pressure value, determining a corresponding system running saturation temperature value; according to the system running saturation temperature value, and a preset temperature control interval, determining the temperature control intervals where the system target running saturation temperature is located, wherein at least two temperature control intervals are arranged; and controlling the rotating speed of the outdoor fan so as to determine the temperature control intervals, where the system target running saturation temperature is located, of the system actual running saturation temperature. Through the method or related equipment, the outdoor fan can be preciselycontrolled, and the multi-split system efficacy can be improved.

Description

technical field [0001] The invention relates to the technical field of electric appliance control, in particular to a method for controlling an outdoor fan of a multi-connected system and related equipment. Background technique [0002] In the use of air conditioners, multi-connected systems are more and more widely used. Among them, the control of the multi-line system has become increasingly important. [0003] In the prior art, the fan control in the multi-connected system is mainly to control the high pressure value of the multi-connected system within a range, and then adjust and control the fan. In the prior art, when the multi-connection system is controlled within this range, the multi-connection system can operate normally. [0004] Obviously, the high pressure control of the multi-connected system has only one control range interval, which is equivalent to the range during the normal operation of the multi-connected system. Obviously, the setting of the control r...

Problems solved by technology

[0004] Obviously, the high pressure control of the multi-connected system has only one control range interval, which is equivalent to the range during the normal operation of the multi-connected system. Obviously, the setting of the control range is relatively large, resulting in low control accuracy for the multi-connected system and low impact on the fan. The adjustment of the operating temperature is not obvious, and the energy consumption of the multi-connected system is relatively high
