Split airco

Types of split air conditioner

A split airco works by transferring heat with refrigerant lines connecting the indoor and outdoor units. A fan blows air over cold evaporator coils in the inside. It removes heat and humidity from the room, putting out cooled, dehumidified air. The outside part has a compressor unit that pumps the refrigerant and an air-condenser that dumps heat seen from outside.

There are several types of split air conditioners:

• Twin-split air conditioner: This type of air conditioner has two indoor units and one outside unit, which make it possible to cool two different rooms with one system. The thermostat or control of a twin-split can be different for both indoor units. Consequently, the temperature of each room can be set according to preference. Installation is easier for a twin-split. Also, when maintenance is required, it's easier and quicker for technicians to reach only one outdoor unit instead of two. The systems are usually more energy-efficient compared to installing two separate AC units. A single outdoor unit consumes less energy in its operations, making it a more efficient option. The units can be multi-connected, which means more indoor units can be connected to one outdoor unit.
• Multi-split air conditioners: Multi-split system air conditioners have several indoor units connected to one outdoor unit. The indoor units are placed in different rooms or zones of a building, and they work to cool or heat those specific areas. Each indoor unit has its ductwork, vents, or air handler, allowing for individualized temperature control in different rooms. The outdoor unit has multiple components like compressors and condensers that work together.
• Inverter air conditioners: These are more efficient than regular models. Inverter models have their compressor speeds continuously adjusted for stable temperatures. Traditional air conditioners keep turning the compressor off and on, causing more power to be used and harsher temperature fluctuations.
• Floor mounted split air conditioners: These units are installed closer to the ground rather than up on the wall like a typical split system. As a result, they have a more flattering appearance to the wall decor. Also, the cold air produced is quickly distributed at a low level and does not have to travel as far to reach the ceiling. This allows for a swift and even cooling of the room.

Function and features of split airco

A split airco comes with many features that improve its performance and make it more convenient to use. Here are some of them:

• High energy efficiency

  Split ACs require less energy to cool a room because they have better heat exchange surfaces. They also cool the room faster, which reduces the amount of time the unit has to run. In general, split ACs use less refrigerant and make less noise than traditional ACs.

• Turbo cooling

  Turbo cooling is a feature that makes the AC cool the room faster. It works by blowing cold air at a faster speed. Many models have a turbo mode in the remote controller. Users can press the turbo button to activate the turbo cooling function. The room will get cool quickly, and users will feel comfortable.

• Self-cleaning

  Split ACs with self-cleaning functions clean their indoor unit automatically. The controller runs the indoor unit's fan at a high speed. Then, the evaporator coils freeze as the air temperature drops. After freezing, the fan blows warm, dry air over the coils. The warm air dries the damp coils and pushes any dust out of the unit. The self-cleaning feature prevents mold growth and keeps the indoor air fresh.

• Wi-Fi connectivity

  Split ACs with Wi-Fi connectivity have indoor units with built-in Wi-Fi modules. They can connect to the local Wi-Fi network. Users can control the AC through a smartphone app or PC. With the app, users can turn the AC on or off, adjust the temperature, and save energy. The Wi-Fi function also allows users to monitor the AC from anywhere.

• Dehumidifier

  All ACs can reduce humidity while cooling the room. But some models have a dedicated dehumidifier function. It works like a dehumidifier and keeps the indoor air comfortable without cooling the air. The dehumidifier function helps to maintain the humidity levels indoors.

• Anti-corrosion protection

  The outdoor unit of the split AC is always exposed to the weather. The anti-corrosion protection ensures that the unit stays in good condition. Many models have a special coating on the outer cabinet to prevent rust. Some units come with treated aluminum parts that resist corrosion and rust better than steel.

Applications of Split Air Conditioner

Domestic and commercial premises widely utilize split air conditioners to produce heating and cooling. The following applications show how versatile the system is.

• Residential cooling and heating: Split ACs have become households' favorite ways to maintain desirable indoor temperatures. They cool rooms during sweltering summers and provide warmth in winter. They are ideal for bedrooms, living areas, and dens.
• Office air conditioning: Offices use split AC units to create comfortable working environments for employees and visitors. They chill in the summer, and office managers install them in meeting rooms, open-plan areas, and private offices.
• Retail business applications: Shopkeepers use split air conditioning systems to keep their goods at safe temperatures and create comfortable shopping areas. Stores use them to cool storage rooms and customer areas.
• Restaurants: Resto owners use split aircon to maintain pleasant dining conditions. The system effectively cools the whole space, even though the kitchen area is very hot. The units in the dining area allow customers to enjoy their meals in a cool room.
• Schools and universities: Educators use split AC units to establish conducive learning environments. Classrooms, libraries, and study areas are some of the most common places to find these gadgets. The air conditioner helps regulate temperature levels for effective learning.
• Healthcare institutions: Hospitals and clinics use split systems to maintain the beds and treatment rooms at suitable temperatures. Healthcare facilities rely on these ACs to promote pleasant working situations for staff members.
• Server rooms and data centers: A split air conditioner effectively cools server rooms to protect servers from overheating. The AC maintains optimal temperature levels, even in the most demanding situations.
• Apartments and condominiums: Developers often install split ACs in individual units to provide residents with independent air conditioning solutions. Each apartment has its own inside and outside unit that works to keep residents comfortable year-round.

How to choose split airco

A buyer should consider some factors before purchasing a split air conditioning system. These factors will help the buyer make the right and best decision that will suit the customer's needs.

• Initial cost vs operating cost: The buyer should consider the initial cost of purchasing and installing the split air conditioning system. Other factors to consider include the cost of electricity and maintenance over time. Reviewing the overall cost of the unit will help make the best decision that is cost-effective.
• Cooling capacity vs space: The cooling capacity of the unit should be matched with the area to be cooled; this is because there are various capacities available to suit different room sizes. The buyer should calculate the BTUs (British Thermal Units) required for each room; this will help fit the right size and model.
• Climate suitability: The buyer must consider the local climate, including the indoor environment where the split AC will be installed. The model suited for high humidity areas will be different from the one used in dry regions. This will aid optimal performance.
• Additional features: Split air conditioning comes with various features that improve comfort and energy efficiency. Buyers should consider features such as programmable timers, Artcool™ Wi-Fi, air purifiers, air quality sensors, remote control, and sleep mode. These features improve the overall comfort and efficiency of the air conditioning system.
