Air Conditioning and Air Conditioner are important part not only for keeping a datacenter cool, but also has been a day to day home appliance for comfort. We are not discussing about Cooling Tower those uses water and prone to harbor various bacterias, fungus etc. microbes. We have discussed on Server Cooling and Datacenter Cooling before. Air Conditioning and Air Conditioner machines are not sufficient for cooling such special units, more arrangements are required. In this article we will discuss only on Air Conditioning and Air Conditioner machine as a home and office appliance.
Air Conditioning and Air Conditioner Machines

Air conditioning is a system for generating and maintaining a uniform indoor climate. A modern Air Conditioning machine is capable of cooling, heating, ventilation, or disinfection that modifies the condition of air either as a centralized system or decentralized machine. Most common usages of a Air Conditioning Machine is for cooling (for home and office), maintaining a sterile environment (in Operation Theaters and Procedure Rooms). A pleasant room climate for humans has a temperature of about 22 ° C and 50% relative humidity.
The modern electrical air conditioning machine was invented by Willis Haviland Carrier.

How a modern Air conditioning Machine works
A typical decentralized Air Conditioning machine unit does a treatment of the air, does filtering, and temperature regulation (usually cooling) through a compressor unit and using a simple refrigeration cycle, coils and fans. Centralized Air conditioners are robust and suitable for cooling and Air Conditioning of larger floor space. Thermostat and other electronic components are added.
Decentralized Air Conditioning machines are usually available as Window Air Conditioning machine unit and Split Air Conditioning machine. Most split air conditioning machine does not introduce outside air for ventilation, unlike Window type and users must be aware of this risk as commercially split is more promoted.
Proper care of Air Conditioning Machine by regular checkup by professionals can avoid the risks with typical system. Users must be aware of the fact that, these small units are quite fragile and not supposed to be resistant to physical insults.
