Split air conditioner

Types of split air conditioners

A split air conditioner has two main parts; the indoor and outdoor units. It's available in different types, including:

• Split Air Conditioners

  The term ""split air conditioner"" refers to the entire AC system. The components consist of an indoor unit that gets mounted on the wall and houses the evaporator coil and blower. The refrigerant lines connect the indoor unit to the outdoor condenser unit. It releases heat captured from inside the premises. The compressor and condenser coil are both housed within the outdoor unit. It works to cool and pump the refrigerant between the two units. A split AC uses inverter technology to provide efficient cooling. Hence, it is popular for residential and commercial cooling applications.

• VRV/VRF Systems

  Variable Refrigerant Volume (VRV) or Variable Refrigerant Flow (VRF) systems are advanced types of split ACs designed to provide multi-zone climate control. A single outdoor unit connects to several indoor units powered by refrigerant. Business owners can individually regulate different indoor unit temperatures. It allows for efficient simultaneous heating and cooling. VRV/VRF systems use inverter-driven compressors for precise refrigerant modulation based on demand. They offer high energy efficiency compared to traditional systems. Also, they provide reliable comfort in large commercial buildings.

• Inverter Split AC

  An inverter split AC is a type fitted with variable-speed compressors. The variable-speed compressors adjust their cooling power based on room load conditions. Inverter ACs regulate indoor temperatures with greater precision and minimize power fluctuations. These enhancements translate to reduced energy consumption and savings. Also, compared to conventional fixed-speed units, inverter air conditioners provide more stable and efficient cooling. Though they have a higher initial cost, inverter ACs are an environmentally sustainable option. They do this by lowering greenhouse gas emissions without compromising comfort.

• Cassette Type Split AC

  Cassette-type split ACs are air conditioners that get cleverly hidden in ceilings. The only thing visible is a sleek, square panel. These cassette ACs evenly spread cool air all over big rooms and offices. They work quietly, leaving the space nice and calm. Installation is easy for suspended ceilings. Four-way air distribution keeps the room comfy. Even though they are a little costlier than regular split ACs, the neat ceiling fit and smooth air cooling make cassette ACs a smart choice for large areas.

Functions and features of split air conditioners

A split AC functions by absorbing heat from inside a room with the help of refrigerant, a gas that cools the air. The refrigerant flows through the indoor unit's coil, evaporating and releasing cool air. The compressor then pumps the refrigerant to the outdoor unit to get rid of the heat. The cycle repeats itself. Besides cooling air, this unit can also heat, dehumidify, and filter the air, providing a comfortable environment.

Split ACs have many features that they can offer to their customers, making them an attractive option for buyers. They include the following :

• Energy efficiency: Split ACs are known to be energy efficient, which in turn means that they will save on costs. In many cases, they are more energy efficient than traditional ACs thus consume less power. Many models also come with variable speed compressors that adjust power consumption according to the cooling needs of a specific room.
• Inverter technology: Many split ACs come equipped with inverter technology, which helps to reduce energy consumption. The inverter technology works by modifying the speed of the compressor instead of switching it on and off, thus maintaining the required temperature. This technology also helps to reduce noise levels, making it a better option for residential areas.
• Eco-friendly refrigerants: Split air conditioners use eco-friendly refrigerants that have little to no effect on the ozone layer. The refrigerants are less harmful to the environment and comply with international regulations for air conditioning systems. They include Hydrofluorocarbons , (HFCs), Hydrocarbons (HCs), and Hydrofluorolefins (HFOs).
• Turbo mode: The turbo mode option in an indoor air conditioner works by instantly cooling or heating a room. Turbo mode works by increasing the AC's fan speed, which in turn raises the set temperature or lowers it rapidly. The mode can be selected from the remote control and is beneficial for rooms exposed to direct sunlight or when the air conditioner has been turned on after some time.
• Dust and electrostatic filter: Split air conditioners have filters that enhance the quality of good air that is emitted from the unit. The filters work by trapping dust, pollen , pet dander, and other microscopic allergens that would otherwise contaminate the air and cause respiratory problems.
• Smart AC: Smart air conditioners are a new trend that has come up in the recent past. They have WiFi connectivity that allows users to control them remotely via an app. Smart ACs also come equipped with voice control features that allow users to control them via voice command.

Scenarios of split air conditioner

Split air conditioners have versatile applications in homes and businesses. Here are some of the popular usage scenarios:

• Residential Cooling and Heating

  One of the main uses of split air conditioning systems is to offer refreshing air in homes. These AC units are ideal for keeping indoor air comfortable when outdoor temperatures reach extremes. They also come with heating functions that can provide warmth during chilly months. Homeowners can enjoy year-round climate control for their living rooms, bedrooms, and kitchens.

• Office Air Conditioning

  Businesses also use split air conditioners to keep their staff and clients comfortable. These ACs offer effective cooling for office spaces. They keep the employees refreshed for maximum productivity. Business owners can install split ACs in their meeting rooms, workstations, lounges, and reception areas. Modern split ACs also come with inverter technology. These energy-efficient air conditioners help to reduce utility bills in commercial establishments.

• Server Room Air Conditioning

  Effective server room air conditioning is critical for any business that heavily relies on IT. Network equipment and servers generate a lot of heat. Split air conditioners can help maintain optimal temperatures in server rooms to avoid equipment failure. IT professionals can install the ACs to ensure consistent cooling around technical systems.

• Hospital Air Conditioning

  The hospital environment needs proper air conditioning for patient comfort and healthcare operations. Split AC units are a great solution for medical facilities. They maintain suitable temperatures in waiting areas, consultation rooms, and recovery wards. With features like air purifiers and dehumidifiers, split ACs improve indoor air quality. Various attachments like ducted split ACs provide cooling for different hospital sections.

• Shop and Restaurant Air Conditioning

  Effective air conditioning keeps customers visiting shops and restaurants. Business owners can use split air conditioners to cool dining areas, bars, and lobbies. AC units with multi-split designs allow for simultaneous cooling in various sections of a business premises. Business operators can also install portable split air conditioners to provide temporary cooling for outdoor patios.

How to Choose split air conditioner

Choosing the right split AC requires consideration of various factors that will ensure comfort and convenience. Here are some of the key factors.

• Cooling load: The foremost factor to consider when selecting an AC is the load. This is the amount of heat generated in a particular space that the AC is expected to handle. It is calculated using different parameters like room height, area, and number of occupants, among others. This figure is represented in either kilowatts or tons. One should not randomly choose a unit; the too-small AC will struggle to cool the room, and the too-large one will cool it too quickly.
• Split AC components: A split AC consists of two main components: the indoor unit and the outdoor unit. The former has a filter, a blower, and a cooling coil, which together provide cool air to the home. It is wall-mounted. The latter, usually mounted outside the house, has a compressor, a fan, and a condenser coil that work together to cool the refrigerant before releasing it back into the atmosphere.
• SPlit AC capacity: Split AC capacity, measured in BTU, denotes how much air an AC can cool. A higher BTU means more cooling power. Many people use the number of tons to refer to AC capacity. One must find the right capacity for their space. Too high, and it cools the space too quickly, or too low, and it takes a long time to cool the room. Calculate the AC capacity using the cooling load determined earlier.
• Star rating: The Energy Efficiency ratio determines the star rating of an AC. A higher star rating means better energy efficiency. Higher-rated ACs cost more, but they are worth the investment because they minimize energy bills. Lower-rated ACs waste energy and cost more money in the long run.
• Thermostat controls: The thermostat control determines the temperature the AC will operate at. An AC with a manual control will have fixed-temperature knobs that the operator should turn. On the other hand, an AC with an automatic control has a digital display and regularly changes the temperature set depending on the room temp.
