Abstract

The utility model provides a low-standby-power-consumption air conditioner intelligent control system. When the air conditioner is in the standby state, the air conditioner intelligent control system detects the indoor temperature and outdoor temperature; and when both the indoor temperature and the outdoor temperature reach the preset temperatures, a main controller controls a power source of an outdoor machine to cut off supply and also controls a switching power source to cut off supply to a stepping motor in an indoor machine. The main controller is powered by a capacitor. Thus, when the air conditioner is in the standby state, the power consumed by the switching power source on the indoor machine is negligible, and the main controller enters a low power consumption mode. At this time, only the main controller and the remote controller receiver consume power, and the power consumption of the whole air conditioner is very low, thereby greatly lowering the power consumption of the standby air conditioner.
