Types of Excel split air conditioners
An Excel split air conditioner is meant to offer efficient cooling to separate areas. Here, the term ""split"" signifies that there are two distinct units: the indoor unit, which is mounted on the wall or positioned within the room to be cooled, and the external unit kept outside the premises. An air conditioner cools a room by circulating and filtering the air within it. There are various types of air conditioners, depending on the number of indoor units.
- Multi-Type Split Air Conditioner: This type of Excel split air conditioner has one external unit but is linked to various indoor units. The number of indoor units can vary, but each room or area that needs to be cooled has its indoor unit. By using a multi-type split air conditioner, one external unit can serve several indoor units, making it a more efficient and space-saving option. The indoor units can be controlled separately so that different temperatures and settings can be kept in other rooms or areas.
- Dual Zone Split Air Conditioner: A dual zone split air conditioner typically consists of one outdoor condenser unit and two indoor air-handling units (zones). It is designed to cool or heat two distinct areas or rooms. A dual-zone system works by having one outdoor unit connected to two indoor units. The two indoor units are installed in different areas or rooms. Each indoor unit can be controlled separately to adjust the temperature and settings. This allows distinct temperatures to be kept in each area or room.
- Triple Zone Split Air Conditioner: A triple zone split air conditioner consists of one outdoor unit and three indoor units. The three indoor units are installed in different areas or rooms. Each unit can be controlled separately, so the temperature can be adjusted differently in each room.
Function and feature of split air conditioner
Functions and features of an air conditioner depend on the specific design and model. A 1-ton split air conditioner and a 2-ton split-unit air conditioner may perform differently due to their capacity. Functions and features include;
- Cooling: A split air conditioner cools rooms and homes. Hot air from indoors comes into the AC, and the compressor separates the hot air from the cold. The cold air is blown back into the room while the hot air is released outside.
- Heating: Some split ACs have in-built heating systems that provide warmth during the cold season. This kind of AC works like a heater, providing warm air when needed. A split AC that offers both heating and cooling is often referred to as a heat pump.
- Air filtration: An air filter is an important device in an AC. The filter captures and traps dust, pollen, mold, and other impurities in the air. This helps to keep the air clean, improve indoor air quality and minimize respiratory problems. Also, the air filter prevents harmful bacteria and viruses from circulating in the room. Some air conditioners have advanced air filters that remove harmful toxins from the air.
- Dehumidification: One important feature of a split AC is dehumidification. All models of split air conditioners reduce humidity levels. When hot, humid air passes over the evaporator coil, condensation happens. This condenses the water, which the AC collects in a drain pan. High humidity can make people uncomfortable, but the AC reduces humidity levels, making the atmosphere comfortable.
- Air distribution: A split AC has louvers that direct airflow. The louvers move up and down to distribute the cold air evenly throughout the room. Even distribution of air prevents hot spots and provides maximum comfort. The louvers may be manually adjusted or automatically move in some split air conditioners.
- Energy efficiency: An inverter split air conditioner is more energy efficient than a traditional air conditioner. It saves power, and people with electricity budget issues prefer it. An AC with a higher energy efficiency rating saves more energy.
- Noise level: A split air conditioner is quieter than a window or portable air conditioner. A split AC with low noise level creates a comfortable atmosphere at home or in the office because low noise is more soothing and relaxing. Some models have a silent operation feature designed for people who prefer absolute silence while sleeping. The silent operation feature produces a low noise level while maintaining a cooling effect.
- Remote control: Almost all models of split air conditioners come with a remote control. The remote control adjusts the air conditioner without getting up from bed or a chair. It offers simple adjustments for temperature settings, fan speed, air direction, and other settings.
