A split air conditioner (AC) is a cooling system divided into two main components: a wall-mounted indoor unit that releases cool air into the room and an outdoor unit containing the noisy compressor and condenser that exhausts heat. These two units are connected by insulated tubing and wiring, allowing for quieter operation, greater energy efficiency, and more flexible placement compared to window AC units.

Key Components

• Indoor Unit:This unit is typically installed on a wall inside the room it serves. It contains the evaporator coil, which absorbs heat from the room, and a fan to circulate the cooled air.

• Outdoor Unit:Located outside the building, this unit houses the compressor and condenser coil. The compressor increases the pressure and temperature of the refrigerant, while the condenser releases this heat to the outside environment.

• Refrigerant Lines:Insulated copper tubes carry the refrigerant between the indoor and outdoor units, facilitating the heat transfer process.

How it Works

1. Heat Absorption:The indoor unit's evaporator coil absorbs heat from the air inside the room.

2. Refrigerant Cycle:The heat is absorbed by the refrigerant, which then travels to the outdoor unit.

3. Heat Release:In the outdoor unit, the condenser releases the absorbed heat to the external environment.

4. Cool Air Delivery:The cooled refrigerant returns to the indoor unit, and the cycle repeats, continuously cooling the air in the room.

Advantages of Split ACs

• Quieter Operation:The noisy compressor is located outdoors, significantly reducing noise levels inside the room.

• Energy Efficiency:Split ACs are generally more energy-efficient than single-unit window air conditioners.

• Flexible Placement:The separated units offer more design flexibility, allowing for cooling in rooms without direct access to an outside wall.

• Better Cooling Performance:They provide more effective and uniform cooling in the spaces they are installed in.
