Abstract

The invention discloses an air conditioner communication control circuit and an air conditioner. The first end of a power supply control loop is connected with a differential mode inductance unit, a first communication module is connected with a common mode inductance unit, the differential mode inductance unit is connected with the first communication module and the common mode inductance unit, the common mode inductance unit is connected with a second communication module, a common connection point of the first end of a short circuit detection unit and the second end of a current detection unit is the first end of the power supply control loop, and the first end of the current detection unit is connected with the first end of a voltage source conduction unit. Parallel connection of differential mode inductors is avoided, so that the communication quality is improved.

Description

technical field [0001] The present application relates to the technical field of air conditioners, and more specifically, to an air conditioner communication control circuit and an air conditioner. Background technique [0002] With the rapid development of technology, the quality of human life is getting higher and higher, and people use more and more multi-connection occasions. Multi-connected air conditioners have strong cooling and heating capabilities, and one outdoor unit can drive multiple indoor units, which reduces the required area for external air conditioners and reduces the construction cost of real estate houses. At the same time, multiple indoor units in the multi-connected system can be controlled by one controller, which also reduces the number of controllers purchased and reduces the cost of air conditioning. When the communication method between the wired controller and the indoor unit is HOMEBUS communication, most of the indoor units are used to supply ...
