Air Conditioner: Types, Installation, and Maintenance

An air conditioner is a device that offers cold air inside an enclosed space or your home by mainly removing humidity and heat from the indoor air. It can return the cooled air to the indoor area and transfer the unwanted humidity and heat outside.

On July 17, 1902, American engineer Willis Haviland Carrier designed the first air-conditioning system. With this, he accomplished a feat that was thought to be impossible previously.

The air conditioner is a member of the family of techniques and systems that offer ventilation, heating, and air conditioning facilities.

Air conditioners typically use a vapor-compression refrigeration system that comes in various sizes, like small and massive units. Small units are used in single rooms or small vehicles, whereas massive ones are used to cooling large buildings.

Air conditioners allow the indoor environment of a building to remain relatively constant without depending on changes in internal heat loads and external weather conditions. They even allow people to live comfortably in hotter areas around the world.

An air conditioner has three main components: a condenser coil, a compressor, and an evaporator coil. It also has a special chemical ingredient, known as a refrigerant, that loops through the system and can absorb and remove heat.

Different Types of Air Conditioners:-

There are various types of air conditioning systems, such as:

  • Split system.
  • Ducted.
  • Multi Split.
  • Controls.

Examples of Air Conditioners:-

There are different types of examples of an air conditioner or an air conditioning system, such as:

Ducted or Mini-Split Systems:

These types of air conditioners mainly supply heated and conditioned air to a single room or even multiple building rooms, have no duct and work in a decentralized manner. Mitsubishi Electric and Toshiba sold the first mini-split devices.

Multi-Split Systems:

Multi-split or multi-zone air conditioning systems are a popular application of ductless systems that allow approximately eight rooms or locations to be conditioned independently.

Ducted Central Systems:

These types of air conditioners are made of an outside unit or a condenser, two heat exchangers, and an internal heat exchanger.

Central Plant Cooling:

Large central cooling plants need to use an intermediate coolant, like chilled water pumped into fan coil units or air handlers, to cool. After that, it can deliver or duct cold air into the areas to be conditioned. Here the chilled water is cooled by chillers.

Packaged Terminal:

The PTAC or packaged terminal air conditioners, window air conditioners, and through-the-wall air conditioners are very similar. A PTAC system can be adapted to offer heating in cold weather, either directly using gas, an electric strip, other heaters, or several other means.

Packaged Air Conditioner:

These types of air conditioners are specific central systems that may integrate into a single housing and offer air through ducts to the areas that need to be cooled.

Applications of Air Conditioners:-

There are different kinds of applications of an air conditioner that can help our world in many ways, such as:

Food Processing and Preservation:

Different types of microscopic organisms can corrupt foods. However, the growth and development of these organisms can be diminished at low temperatures. Thus, air conditioning systems are widely used to maintain the good quality of different types of foods and dairy products.

Chemical Industries:

Industries like petrochemical plants, petroleum refineries, and paper mash industries need substantial cooling limits and hence, need to use air conditioning systems to a great extent.

Home and Offices:

Air conditioners help us by offering a comfortable temperature within our houses and offices, even in extreme weather conditions.

Special Applications:

Air conditioners are also useful to the medical industry as they help preserve antibiotics, blood plasma, and many more.

Therefore, this article has provided some vital information about air conditioners.

Key Takeaways:

  1. Air conditioners work by removing heat and moisture from the air.
  2. The invention of air conditioning has transformed the way we live and work in hot climates.
  3. Air conditioning units can harm the environment and contribute to global warming.
  4. There are ways to reduce the negative impact of air conditioning, such as using energy-efficient units and implementing passive cooling techniques.
