Abstract

The present application relates to the technical field of air conditioners, and discloses a circuit for identifying an outdoor unit with low standby power consumption. The circuit for identifying an outdoor unit with low standby power consumption includes: an internal unit communication circuit that communicates with the external unit communication circuit in the outdoor unit through a signal line, a conduction direction switching circuit connected in series with the DC power supply branch of the signal line, Wherein, when the conduction direction switching circuit is in the first conduction state, the conduction direction of the conduction direction switching circuit is opposite to the current direction of the DC power supply branch. When judging whether an outdoor unit is an outdoor unit with low standby power consumption, using the circuit for identifying an outdoor unit with low standby power consumption can improve the accuracy of the judgment result. The application also discloses an air conditioner.

Description

technical field [0001] The present application relates to the technical field of air conditioners, for example, to a circuit for identifying an outdoor unit with low standby power consumption and the air conditioner. Background technique [0002] At present, when the outdoor unit with low standby power consumption is in standby, all power supplies of all outdoor units can be cut off, and only the control circuit of the indoor unit is supplied with power, thereby reducing power consumption. Low standby power consumption outdoor units and non-low standby power consumption outdoor units use different communication protocols and different control strategies. The control strategy controls the outdoor unit. [0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in related technologies: [0004] When judging whether the outdoor unit is a low standby power consumption outdoor unit, backflow is likel...
