Mechanical Air conditioning - Part I -- Operating Principle

Common ACs, associated with see almost everywhere on this globe, is actually, the mechanical usually AC unit. If we may be very meticulous in the same naming structure, we possess called it Mechanical ACs.

However, we name it as air conditioner, or ACs, and is aware it.

One should not confuse the definition of between, Air Conditioning, and AC. Air Conditioning will mean altering temperature, humidity, air filtration, movement and joining. Whilst ACs are the instruments used to alter your skin temperature and humidity - from a single package.

There are four form air conditioners available upon us. The,

• gas uptake AC,


• steam based COOLING,


• thermoelectric AC, and


• the mechanical AC

The first of all three AC types made for professionals (if not totally) great for industrial applications. We'll check out the air conditioner operation, instant, before concentrating on mechanical air conditioners.

Gas absorption AC

Uses, water since its refrigerant. The system comes with the principle of vacuum, when promoting boiling of water at very cheap temperature. The water have proven to be passed through cooling coil nailers, for producing cool ambiance.

Lithium bromide will also become the absorption (or recovery) tactic, once the water has transpired through the cooling coil nailers.

Steam based ACs

Is due to gas absorption units, even so uses the brute power of steam, and venturi, to less the pressure of water (which comes with the refrigerant).

Water at low hazards will boil at cold, and becomes a refrigerant.

Thermoelectric AC

This AC comes with the principle of thermocouple to attain the heating system effects using this method. The beauty of this method lies in its ease of construction.

It uses electrical power, and thermocouple. As the force flows through the route, you'll get a pot region, and a the winter season region. Talk about ending two birds with a person stone.

However, the major limitation associated with the concept is that, this only produce a low cooling or heating cause, compared to other air conditioning units.

Mechanical Air Conditioners

It is termed a mechanical, as it requires the continuous act of refrigerant compression for cooling, or heating effect. This concept was thought by Willis Haviland Carrier, when he created the first mechanical element.

Special refrigerant are used to arrive to this. These are known as CFCs (already banned), HCFCs and so you, HFCs. Why use these? Because of very uncouth boiling temperatures, at outer pressure.

Details of this air conditioner operation,

• a compression process must raise the pressure up refrigerant. When this is released, you can liquefy your refrigerant (through condensation) in the correct way,


• this is followed by having an refrigerant condensation. Condensation visits through heat exchange through refrigerant, and air (or water),


• an expansion device (or valve) is placed after the condenser. This will be a device to allow for pressure work up from compressor. This are also, the place where refrigerant carries out evaporate into low trigger region.

  When this happens refrigerant are going to boil at very summary temperatures,



• finally, the refrigerant is passed through another heat exchanger - the style the boiling process. Heat exchange happens totally from air and refrigerant


• this process repeats ahead of the compression side

Those are the processes involved in achieving cool air, through mechanical air conditioning - through continuous "supply" of refrigerant at low conditions.

Part II is coming soon...
