Abstract

The invention discloses a communication switching circuit and an air conditioner. The communication switching circuit comprises a first switch unit and a second switch unit, wherein the first switch unit is used for sending a first communication signal of a first indoor unit control unit to an outdoor unit control unit and sending a first outdoor unit communication signal of the outdoor unit control unit to a first communication unit; the second switch unit is used for sending a second communication signal of a second indoor unit control unit to the outdoor unit control unit and sending a second outdoor unit communication signal of the outdoor unit control unit to a second communication unit; and the first switch unit and the second switch unit are arranged in the circuit to switch the two communication circuits, so that the indoor unit compatible with different communication circuits based on one outdoor unit is realized, and the cost is reduced.

Description

technical field [0001] The present application relates to the field of air conditioner control, and more specifically, to a communication conversion circuit and an air conditioner. Background technique [0002] AHU (Air handling unit, air handling unit) air conditioner is a combined air conditioning box, which mainly extracts indoor air and some fresh air to control the temperature and air volume of the outlet air to maintain the indoor temperature. [0003] Ducted air conditioner, commonly known as ducted machine. The air conditioner is connected to the air duct to supply air to the room, which is a small all-air system. [0004] Patio machine air conditioner, also known as ceiling machine or ceiling type, embedded air conditioner. [0005] For the communication circuit of indoor unit and outdoor unit, the indoor unit of AHU air conditioner is the first type of communication circuit based on the one-way communication of the wire controller. Based on this first type of com...
