Businesses such as IT companies, Hospitals, hotels, manufacturing factories, etc where there are huge number of employees and lot of heat generating equipments are present require business air conditioning systems which can circulate fresh air and remove heat from office space.
Most of modern factory air conditioning systems use split air conditioning or ductless systems. The condenser and cooling units of these business air conditioning systems are usually located on roof tops far away from office space to avoid disturbance to workers through noise created by motors. All modern business air conditioning systems have thermostat controlled cooling systems and ducted cooling system employed in centralized air conditioners is mostly avoided due to lack of efficiency but are still used in certain commercial building. There are various cooling techniques available in such business air conditioning systems such as chilled water cooling, air cooling, glycol cooling and water cooling.
Water cooled Business Air conditioning units
In water cooled business air conditioning units, water will be cooled inside cooling tower and is relayed back to heat exchanger that is installed inside the office space. By using water cooled business air conditioning units, multiple office spaces can be chilled using single cooling tower and it requires proper maintenance of tower and good quality water for good efficiency.
Air cooled Business Air conditioning units:
The air cooled business air conditioning units are used widely due to easy installation and maintenance as they are ductless in nature. The condenser unit is placed on roof top that helps to remove hot air inside office space and the blowers will blow fresh air into building. The cooling pipes cannot be very long and hence the height of building should be less for such air cooled business air conditioning systems.
Chilled water Business Air conditioning system:
In chilled industrial air conditioning unit, the entire system lives on roof top or at back of the building. The cooling towers present in chiller plant can cool water to around 4.4-7 degree Celsius by blowing air which causes evaporation of water that in turn produces a cooling effect. This chilled water is then piped throughout the office and they are linked to air handlers as required. The amount of cooling produced by such chilled water business air conditioning unit depends on barometric pressure and relative humidity. The air conditioning installations are very expensive for such systems and they are suitable for larger areas.
Glycol cooled Business Air conditioning systems
Such emergency air conditioning systems are very sophisticated and can achieve temperature below 10 degree Celsius and ethylene glycol is used as coolant in such business air conditioning units. The quantity and quality of glycol should be high for such industrial air conditioning units and maintenance could be expensive.
Portable room Air Conditioners:
These business air conditioning units are suitable for small office space with area less than 500 square feet. Most popular are Amcor portable air conditioners which are eco-friendly and make use of innovative evaporative injection technology to suck moisture from air to produce instant cooling effect.
The industrial air conditioning units must be chosen based on requirements such as type and size of office building, budget and number of employees. Air conditioning sales is very high during summer when the heat is unbearable in office.
