Air Conditioning and Conditioning Systems
Commercial air conditioning comes in both centrally driven systems and local systems. Traditionally offices tended to have a central cooling and heating fan unit whereby the temperature controlled air is distributed throughout the building by a system of ceiling or floor ducts.
A series of ventilation grills and baffles are balanced to ensue an even air distribution throughout the building.
The concept of air conditioning is thought to date back to ancient Rome, were water supplied direct by aqueducts was allowed to run between the walls of buildings to cool them. The Chinese used water to turn turbines or fans in order to create cool spaces in a building.
Similar techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the summer season. The air conditioning we see today is based on these ancient principles, however advances in the use of chemistry during the 19th century led to the first large scale modern type of air conditioning unit being 'invented' and used in 1902.
If inverter units are used in commercial buildings, these are often ceiling cassettes which come in a variety of specifications (1, 2 and 4 way cassettes). Perimeter areas and corridor areas often use air conditioning console units.
Process applications aim to provide a suitable environment for a process being carried out, regardless of internal heat and humidity loads and external weather conditions. Although often in the comfort range, it is the needs of the process that determine conditions, not human preference.
Air conditioning systems have the ability to effectively be 'run in reverse', thereby also acting as a heat pump. This is an extremely efficient use of electricity in providing domestic heating by provision of warm blow air.
However measures are in place to oversee the development of greener air conditioners, where a difference of up to 200% can be seen when compared to traditional units.
