Title:
CIRCUIT FOR IDENTIFYING OUTDOOR UNIT HAVING LOW STANDBY POWER CONSUMPTION, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2021/027199
Kind Code:
A1
Abstract:
The present application relates to the technical field of air conditioners, and provides a circuit for identifying an outdoor unit having low standby power consumption. The circuit for identifying an outdoor unit having low standby power consumption comprises: an indoor unit communication circuit communicating with an outdoor unit communication circuit in an outdoor unit by means of a signal line, and a conduction direction switching circuit connected in series to a direct current power supply branch circuit of the signal line, wherein when the conduction direction switching circuit is in a first conduction state, the conduction direction of the conduction direction switching circuit is opposite to the current direction of the direct current power supply branch circuit. When determining whether an outdoor unit is an outdoor unit having low standby power consumption, the use of the circuit for identifying an outdoor unit having low standby power consumption can improve the accuracy of the determining result. Also disclosed in the present application is an air conditioner.
