Refrigerant System Diagram
This diagram illustrates the refrigerant flow for cooling and heating modes. Key components include:
- Compressor: Compresses the refrigerant.
- Mufflers: Located after the compressor and before the 4-way valve to reduce noise.
- 3-Way Valve: Controls refrigerant flow direction.
- Heat Exchanger (Indoor): Facilitates heat transfer with the indoor air.
- 4-Way Valve: Reverses the refrigerant flow for switching between cooling and heating.
- Heat Exchanger (Outdoor): Facilitates heat transfer with the outdoor air.
- 2-Way Valve: Controls refrigerant flow.
- Strainers: Filter the refrigerant.
- Expansion Valve: Reduces refrigerant pressure.
Arrows indicate the direction of refrigerant flow for Cooling (solid arrows) and Heating (dashed arrows).
Refrigerant Pipe Diameter: Liquid line: 1/4" (6.35 mm), Gas line: 3/8" (9.52 mm).
Circuit Diagram
The circuit diagram details the electrical connections for both the Indoor and Outdoor Units.
Indoor Unit Circuit
The indoor unit circuit includes connections for the Fan Motor, Display Board, Power Relay, Thermistors (room and pipe temperature), Stepping Motor, and the Controller PCB. Power is supplied via terminals and a power source connection. Wires are color-coded (e.g., RED, WHITE, BLACK, BLUE, GREEN/YELLOW).
Outdoor Unit Circuit
The outdoor unit circuit features a PCB (MAIN) that connects to the Compressor, Fan Motor (FM), Expansion Valve (PMV), and 4-Way Valve Assy. It also includes Reactors, Thermistors (discharge pipe, pipe, outdoor temperature), and a Fuse (250V 20A) connected to terminals.
Indoor PCB Circuit Diagram
This detailed schematic shows the internal circuitry of the Indoor Unit's Printed Circuit Board (PCB). It includes various integrated circuits (ICs), resistors, capacitors, transistors, connectors (CN6, CN3, CN7, CN201), and jumper wire configurations (JM1, JM2) for custom code and auto-restart settings. Components like the Fan Motor (FM), Louver motor, and Indicator PCB are connected.
Outdoor PCB Circuit Diagram
This diagram illustrates the circuitry of the Outdoor Unit's PCB. It shows connections to the Inverter Assembly, Compressor, Fan Motor (FM), Expansion Valve, and 4-Way Valve. Components include thermistors for discharge, pipe, and outdoor temperature, as well as EMI filter and reactor.
Controller PCB Assembly (Outdoor Unit) Circuit Diagram
This is a highly detailed schematic of the Outdoor Unit's Controller PCB. It depicts numerous ICs (e.g., BA4560, BA2903F, BA2902F, MB90460), transistors, resistors, capacitors, connectors (CN71, CN70, CN40, CN30, CN801, CN580), and power components like the Inverter Assembly. It maps out the complex interconnections for controlling the air conditioner's functions.
