Air Conditioning Split AC Wiring Diagram

When it comes to installing or troubleshooting an air conditioning split AC, knowledge of the wiring diagram is crucial. The split AC consists of two main components – the indoor unit and the outdoor unit. Both units are connected by electrical wiring and piping, and in this article, we will focus on the wiring diagram.

Indoor Unit Wiring Diagram

The indoor unit is responsible for blowing cool air into the room. It consists of several key components that are connected by wiring, including:

Component Wiring Connection
Power supply Connects to the electrical panel
Thermostat Connects to the control board
Control board Connects to the power supply, thermostat, and other internal components
Blower motor Connects to the control board
Evaporator coil Connects to the refrigerant lines and the blower motor

Understanding the wiring connections between these components is important for proper installation and troubleshooting.

Power Supply Connection

The power supply connection involves connecting the indoor unit to the electrical panel. This involves running a dedicated circuit and installing a circuit breaker to handle the electrical load. The wiring diagram will indicate the proper wire gauge and breaker size for the specific AC unit.

Thermostat Connection

The thermostat connection involves connecting the thermostat to the control board. This allows the thermostat to communicate with the indoor unit and control the temperature in the room. Proper wiring of the thermostat is essential for accurate temperature control.

Control Board Connection

The control board is the central component of the indoor unit. It connects all the internal components and allows them to communicate with each other. Proper wiring of the control board is essential for the indoor unit to function properly.

Blower Motor Connection

The blower motor is responsible for blowing cool air into the room. It connects to the control board and is controlled by it. Proper wiring of the blower motor is essential for efficient and effective cooling.

Evaporator Coil Connection

The evaporator coil is the component that cools the air. It connects to the refrigerant lines and the blower motor. Proper wiring of the evaporator coil is essential for proper cooling and preventing damage to the AC unit.

Outdoor Unit Wiring Diagram

The outdoor unit is responsible for extracting heat from the room and releasing it outside. It consists of several key components that are connected by wiring, including:

Component Wiring Connection
Power supply Connects to the electrical panel
Compressor Connects to the control board and the condenser fan motor
Condenser fan motor Connects to the control board and the power supply
Condenser coil Connects to the refrigerant lines and the compressor

Understanding the wiring connections between these components is important for proper installation and troubleshooting.

Power Supply Connection

The power supply connection involves connecting the outdoor unit to the electrical panel. This involves running a dedicated circuit and installing a circuit breaker to handle the electrical load. The wiring diagram will indicate the proper wire gauge and breaker size for the specific AC unit.

Compressor Connection

The compressor is the heart of the outdoor unit. It compresses the refrigerant, which causes it to release heat. It connects to the control board and the condenser fan motor. Proper wiring of the compressor is essential for efficient and effective cooling.

Condenser Fan Motor Connection

The condenser fan motor is responsible for extracting heat from the condenser coil and releasing it outside. It connects to the control board and the power supply. Proper wiring of the condenser fan motor is essential for efficient and effective cooling.

Condenser Coil Connection

The condenser coil is the component that releases heat outside. It connects to the refrigerant lines and the compressor. Proper wiring of the condenser coil is essential for efficient and effective cooling.
