Industrial Air Conditioners

Most commercial spaces including offices, hospitals restaurants, and shoppingmalls have a variety ofelectronic devices which are needed for smooth running of respective business. A deadlyenemy of the electronicsystems, such as computers, electronic testing systems, and others of the ilk is heat. Moreover, comfort, health, and productivity of people working in these areas are also concerns. An air conditioner (AC) is an ideal defenceagainst heat and pollutants. Consequently,most commercial spacestoday are fitted with massive AC system to maintain the optimum temperature.

The air conditioning systems used in industries can be classified in two categories – ductless and ducted airconditioning systems, or a combination of both.

Ductless systems: In ductless systems thecooling machinery, fans, compressors, condensers, cooling towers, condensate recovery, and discharge components are located inside an external unit. This unitis placed at a remote location outside the facility on the roof or on the ground adjacent to the building. There are indoor units which are mounted on walls or ceiling. These have the air handler with heat exchanger and a fan. The refrigerant is sent from the outdoor unit to the inside one for cooling. These room units have individual thermostats that can set different temperature for different rooms.

There are some benefits of ductless industrial ACs. They are easy to install as they do not require laying ducts. They also allow the flexibility in placing the air handler. They allow maintaining temperatures according to the needin a room. They are a good solution in high load conditions, e.g. a commercial kitchen space which have hot ovens. A centralized system will not be able to doa justice here. They are noiseless.

However, ductless ACs also have someflipsides. Being ductless they cannot doa good air circulation indoors. This can augment the humidity level and compromise the air quality inside. They also occupy a good amount of wall space. As the refrigerant and the condensate travel between externalunit and the inside one, these can cause lines on both interior and exterior walls.There will be potential energy losses from long refrigerant lines. Ductless replacements and retrofit systems are quite expensive for large rooms.

In some special cases ductless ACs are most suitable. If you are adding rooms to your commercial space, it will be a hassle to extend you duct to them.There can be rooms which neither have ducts nor have enough space to build them.In such conditions these ACs are ideal for cooling.

Ducted ACs: Mostcommercial buildings in the U.S. are built with air ducts. These ducts are usually made of sheet. They run from the central air conditioning unit to individual rooms. These ducts are hidden in ceilings and walls and have vents through which the air is delivered.

Invariably, a ducted air conditioning system is more expensive than a ductless system. However, its main benefit liesin the fact that it will cool the whole space. It is generally controlledbya centrally located thermostat and it maintains uniform temperatureeverywhere. Maintaining an even temperature makes it congenial for your flooring, furniture, and pets. However, today you get ducted systems that can be zoned. This means you can turn off cooling in certain rooms that you are not using. You canalso cool different rooms todifferent temperatures. However, zonedsystems are most costly than basic central ACs. Ducted ACs are efficient air filterers and canmaintain optimal humidity. They respond to temperature changes quickly.

Thecentralsystems can reverse the cooling cycle to heatthe spaces in winter. If you buy systems thatare capable of being reverse cycle units, you may have to make a fat investment. But it will save you other costs. You will neither need to buyseparate heating systems nor makemultipleducts in each room for heating and cooling. Modern ducted systems have becomemore quite than older models. They are more feasible when you have a permanent house where you plan to stay for long.

The size and capacity of industrial air conditioning will be based on the size and design of the facility to be cooled. Their size can range from some two tonsto 150 tons. 150 tons AC will have 1,800,000 BTU. The BTU rate measure the capacity of air conditioners.
