The purpose of an air conditioner is to maintain a comfortable indoor environment. The comfort we are used is to determined by a combination of 3 factors.

• Temperature
• Humidity
• Air Distribution

For this reason, the main purposes of air conditioners are to:

• Control room temperatures (cooling/heating).
• Control room humidity levels (drying, humidifying).
• Optimize air flow (circulation, distribution).
• Clean the air (filtration)

Working principle

An air conditioner collects hot air from a given space, processes it within itself with the help of a refrigerant and a bunch of coils and then releases cool air into the same space where the hot air had originally been collected. This is essentially how all air conditioners work.

Many folks believe that an air conditioner produces chilled air with the help of machines installed inside it, allowing it to cool a room so quickly. That might also explain why it consumes so much electricity. In reality, however, that’s a misconception. An air conditioner is not a magical device; it just uses some physical and chemical phenomena very effectively to cool a given space.

When you switch an AC on and set your desired temperature (say, 20 degrees Celsius), the thermostat installed in it senses that there is a difference in the temperature of the room’s air and the temperature that you’ve chosen.

A thermostat constantly monitors the temperature of the system so that it’s maintained near a user’s desired point.

This warm air is drawn in through a grille at the base of the indoor unit, which then flows over some pipes through which the refrigerant (i.e., a coolant fluid) is flowing. The refrigerant liquid absorbs the heat and becomes a hot gas itself. This is how heat is removed from the air that falls on the evaporator coils. Note that the evaporator coil not only absorbs heat, but also wrings out moisture from the incoming air, which helps to dehumidify the room.

This hot refrigerant gas is then passed on to the compressor (located on the outside unit). Being true to its name, the compressor compresses the gas so that it becomes hot, since compressing a gas increases its temperature.

This hot, high-pressure gas then travels to the third component – the condenser. Again, the condenser remains true to its name, and condenses the hot gas so that it becomes a liquid.

The refrigerant reaches the condenser as a hot gas, but quickly becomes a cooler liquid because the heat of the ‘hot gas’ is dissipated to the surroundings through metal fins. So, as the refrigerant leaves the condenser, it loses its heat and becomes a cooler liquid. This flows through an expansion valve – a tiny hole in the system’s copper tubing – which controls the flow of cool liquid refrigerant into the evaporator, so the refrigerant arrives at the point where its journey started.

Here’s a simplified diagram of the air-conditioning process:

Although all the components involved in the air-conditioning process in window ACs are located inside the same metal box, the underlying process of cooling remains exactly the same.

The entire process is repeated over and over again until the desired temperature is attained. In a nutshell, an AC unit keeps drawing in warm air and expelling it back into the room until there’s no more warm air left to cool.

SPLIT AIR CONDITIONER

A split air conditioning imply means that the condenser (or sometimes referred to as the “outdoor unit”) is separated from the “indoor unit”, thus the term “split”.

The split air conditioning has at least one unit that sits inside your room. The compressor sits outside of the room, sometimes on the ground or on brackets hung to the wall. Some models come with multiple indoor units that will use one single compressor, this is known as the multisplit air conditioning system.

A split air conditioner consists of two main parts: the outdoor unit and the indoor unit. The outdoor unit is installed on or near the wall outside of the room or space that you wish to cool. The unit houses the compressor, condenser coil and the expansion coil or capillary tubing. The sleek-looking indoor unit contains the cooling coil, a long blower and an air filter.

A split air conditioner is a suitable alternative to wall, window, or centralized air conditioner systems. Often called mini-split, ductless split, or duct-free air conditioning, this system can adequately cool a standard-sized house without requiring extensive installation costs and efforts.

Split air conditioners are home appliances that do not require ductwork, which reduces energy expenditures. Still, many homeowners shy away from a split air conditioner system because they do not know how it works or why it is a viable option for cooling down.

The following information will fill you in on the function and installation of split air conditioner systems. They are uncommon, but not through any fault or flaw.

CONSTRUCTION

The split air conditioner comprises of two parts: the outdoor unit and the indoor unit. The outdoor unit, fitted outside the room, houses components like the compressor, condenser and the expansion valve. The indoor unit comprises the evaporator or cooling coil and the cooling fan. For this unit, you don’t have to make any slot in the wall of the room. Further, present day split units have aesthetic appeal and do not take up as much space as the window unit. A split air conditioner can be used to cool one or two rooms.
