Comparing split AC and window AC: Operation, functionality, and applications

What is a split AC?

A split AC system consists of two main units which is an indoor unit that cools the air inside the room, and an outdoor unit that expels heat outside. For example, in a bedroom, the indoor unit is mounted high on a wall to distribute cool air evenly, while the outdoor unit sits outside on a balcony or rooftop.

How does a split AC work?

Inside the indoor unit, a cooling coil cools down warm air drawn from the room using refrigerant. This cooled air is then circulated back into the room by a fan. Simultaneously, the outdoor unit houses a compressor and condenser coil that release the absorbed heat outside, allowing the refrigerant to cool and repeat the process. Suppose this process is a continuous loop where warm air is drawn in, cooled, and then circulated back out.

Key features of split AC

Split ACs are known for their quiet operation, energy efficiency, and precise temperature control. They often come with convenient features like remote control operation, programmable timers, and sleep mode, making them user-friendly and comfortable to use.

Common uses and installation of split AC

Split ACs are highly sought after in homes, offices, and shops where maintaining a serene environment is paramount. They're the perfect solution for rooms where conventional window installations aren't feasible whether due to space constraints or strict building regulations. Installing a split AC involves expertly mounting the indoor unit on a wall and strategically placing the outdoor unit in a well-ventilated area. This not only ensures optimal performance but also enhances the overall efficiency and lifespan of the system, making it an ideal choice for those seeking both comfort and practicality in their cooling solutions.

What is a window AC?

A window AC is a standalone cooling system that you install directly in a window or through a wall opening. It's commonly used in residential settings where a central HVAC system may be impractical or unnecessary.

How does it work?

Inside the unit, warm air from the room is drawn in through the front grille and passed over the evaporator coils. These coils contain refrigerant that absorbs heat from the air, cooling it down. The cooled air is then blown back into the room, while the absorbed heat and moisture are expelled through the exhaust vents at the back of the unit, usually outside through the window.

Key features

Window AC units are appreciated for their simplicity and effectiveness. They're easy to install and typically more affordable than split AC systems. Many models come with features like adjustable fan speeds, remote controls, and programmable timers for added convenience.

Common uses and typical installation scenarios

Window ACs are commonly used in bedrooms, living rooms, and small apartments where cooling specific areas is necessary. They're particularly suitable for spaces with windows that can accommodate the unit's size and ventilation needs. Installation involves fitting the unit securely into a window frame or through a wall, ensuring it's properly supported and sealed to prevent air leakage and maximise efficiency.
