Control device, air conditioner controller, air conditioner and control method of air conditioner

Abstract

The invention discloses a control device, an air conditioner controller, an air conditioner and a control method of the air conditioner. The control device is applied to the air conditioner and comprises a first communication unit of a first control panel, a second communication unit and a power supply circuit of a second control board, and a third communication unit and a control unit of a third control board; the first communication unit comprises a first sending unit and a first receiving unit, the second communication unit comprises a second sending unit and a second receiving unit, the third communication unit comprises a third sending unit and a third receiving unit, and the first sending unit, the first receiving unit, the second sending unit, the second receiving unit and the third receiving unit are connected in series, and the third sending unit is connected in parallel with the second sending unit. In a communication state, the third sending unit and the second sending unit are connected in parallel, only one is in a working state, and the other is in a turn-off state. The standby power consumption of the air conditioner can be effectively reduced, and the structure is simple, the anti-interference performance is high, the reliability is high, and the control is easy.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control device, an air conditioner controller, an air conditioner and a control method thereof. Background technique [0002] At present, for air conditioners, such as inverter air conditioners, the power supply methods mainly include the following two types: [0003] One is the false outdoor power supply method, that is, the mains power is directly connected to the indoor unit through the cable through the terminal of the outdoor unit, and the indoor unit performs low standby power consumption control. Here, an additional power supply between the indoor and outdoor units is required. The cable wires not only increase the cost, but also increase the complexity of the circuit. [0004] The other is to monitor the communication signals of the indoor and outdoor units. When a communication signal is detected, the power supply of the outdoor unit is turned on. If no commu...

AI Technical Summary

Problems solved by technology

Since this solution uses hardware circuits for communication signal detection, the circuit is complex and susceptible to interference, and the control signal of the on-off control circuit is obtained by signal detection of communication signals. Therefore, facing the life of the air conditioner for more than ten years, its There are also deficiencies in reliability and work stability
