Everything about Air Conditoners which Every Electrical Engineer Should know

Air conditioners are popular cooling devices which don’t need any introduction. In this post you’ll learn:
  1. Types of Air Conditioners [Construction] – Split vs Windows vs Portable
  2. Types of Air conditioner [Technology] – Inverter vs Noninverter
  3. What are Tons
  4. How to size ac for your room
  5. Practical Applications

Parts of air conditioner

  1. Blower: The front component in the indoor units which pulls normal air from the room.
  2. Evaporator coil: Next to the blower is an evaporator coil which takes humidity and heat (in the form of gases)from the air.
  3. Compressor: It compresses the gases by pressurizing them.
  4. Condensor: It is installed in the outdoor unit and it cools down the refrigerant.
  5. Fan: It is used to cool the condenser components.
  6. Thermostat: It reads the temperature and sets the ac to achieve the desired temperature.

Types of Air Conditioners on the Basics of Construction

  1. Split: It has separate indoor and outdoor units. They are widely used in homes and offices.
  2. Window: They contain indoor and outdoor units in a single box and are installed in walls.
  3. Portable: They are modern portable devices some of which are similar to split types ac’s, while others have cooling ducts.

Types of Air conditioners on the Basis of technology: Inverter vs Non-inverter AC

On the basis of technology, AC’s are divided into two types.
  1. Non-Inverter: As the name indicates they are old ac units which don’t contain inverter unit.
  2. Inverter: Inverter air conditioners are advanced models of air conditioners which contain a variable frequency drive. It adjusts the frequency to a useful level which increases the efficiency and lifespan of the overall system.

What are tons

The ton is unit of cooling where 1 ton equals 3.6 kW. It is a unit of gross internal capacity which equals 100 cubic feet. One ton is also defined as the refrigerating power which is able to freeze 2,000 pounds of water at 0°C in a day.

How to size the AC for Room

Practical applications of AC

  1. Used in industries for cooling the large electrical and mechanical structures
  2. Used in chemical, medical, and biological labs
  3. Used in nuclear power plants
  4. Data centers, workstations
  5. Employed in homes and offices
