Air-conditioning System consists of a gaggle of components or equipment connected serial to regulate the environmental parameters.
“An air-conditioning system, by ASHRAE (American Society of Heating,Refrigerating and Air-Conditioning Engineers) definition is a system that has got to accomplish four objectives simultaneously.”
These objectives are to control:
The cooling is usually done using a simple refrigeration cycle, but sometimes evaporation is employed , commonly for comfort cooling in buildings and automobiles . In construction, a complete system of heating, ventilation and air conditioning is mentioned as “HVAC”.
Air conditioner is needed in several sections and units for efficiently cool room air during ,Delivery Rooms, Treatment Rooms, Patient Care Rooms, Nurseries Intensive Care Units, diagnostic and related areas, laboratories and Sterile Storage. Air conditioning is used in hospital for efficiently remove from the air microorganisms, dust, soot, and other foreign bodies.
Technically word for this type of System is “unitary” air conditioning system and comprised of it’s own air conditioning unit that’s placed during a window or through a hole in an exterior wall. Since adding holes in your homes outside walls aren’t a very good idea, these units are nearly always placed during a window. The all the refrigeration components of Window air conditioner is in one
compact box. It removes out heat from one end and supplies cool air from the opposite end.

In a split-system, an outside metal cabinet contains the condenser and compressor, and an inside cabinet contains the evaporator. In many split-system air conditioners, this indoor cabinet also contains a furnace or the indoor a part of a apparatus . The air conditioner’s evaporator coil is installed within the cabinet or main supply duct of this furnace or apparatus . If your home already has a furnace but no air conditioning , a split-system is that the most economical central air conditioning to put in .
In a central air conditioning , the evaporator, condenser, and compressor all are placed and fixed at one place and inside a one cabinet, which is usually kept on a roof or on a concrete slab according to the requirement next to the house’s foundation. this sort of air of user. conditioner is also utilized in small commercial buildings.Air supply and return ducts come from indoors through the home’s exterior wall or roof to attach with the packaged air conditioning , which is typically located outdoors. Packaged air conditioners often include electric heating coils or a gas furnace. This combination of air conditioning and central heater eliminates the necessity for a separate furnace indoors.

This system is another flavor of the unitary air conditioning system. The portable air conditioning consists of a mobile self contained air con unit that is placed on the ground inside an area and discharges extreme heat employing a hose channel through an exterior wall. Portable air con units are a touch noisier than other types of units and may typically cool rooms under 500 Sq.ft. These units are an answer to those stubborn hot rooms which will exist even with central air con . Like the window air conditioning , the portable unitary system has all the refrigeration components on one compact box. It also ejects heat out one end and blow cooled air out the opposite end.
