Abstract

The invention discloses a communication device of an indoor unit and an outdoor unit of an air conditioner, the air conditioner and a communication method of the indoor unit and the outdoor unit of the air conditioner. The communication device comprises an isolation device and a power supply device, wherein the isolation device is used for isolating a communication circuit from a control circuit of an indoor unit and outdoor unit controller of the air conditioner; and the power supply device is used for supplying power to the communication circuit and the control circuit of the indoor unit andoutdoor unit controller under the situation that the communication circuit and the control circuit of the indoor unit and outdoor unit controller are isolated. According to the scheme, the problem that in the prior art, communication nodes of the indoor unit and the outdoor unit of the air conditioner are connected to respective local ground, and communication safety is poor can be solved, and the effect of improving the communication safety is achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a communication device for internal and external units of an air conditioner, a communication method for an air conditioner and its internal and external units, and in particular to a device for fully isolating 485 communication circuits with a 48V power supply controller, an air conditioner with the device, and The communication method of the internal and external units of the air conditioner. Background technique [0002] The existing household air conditioner controllers generally use 220V AC power supply methods. 48V power supply air conditioners have been used in automobile air conditioners, and the 48V power supply of household air conditioners has gradually become the object of research. 48V DC transmission power has good stability and low loss. , and is more secure than alternating current. Directly connect the communication nodes of the air conditio...
