Industrial Air Conditioners
What is a commercial or industrial air conditioning system and how does it work?
What is an Air-conditioner?
An air-conditioner is a device or system that lowers the air temperature. Typically, the cooling of the air is achieved through a refrigeration cycle, but sometimes evaporation or free cooling is used.
In all applications, the aim is not only to control the temperature but also other factors such as humidity, air movement and air quality.
Air-conditioning (AC) in general can refer to any form of technology that modifies the condition of air such as heating, cooling, dehumidifying, cleaning, ventilation or air movement. In the construction industry, however, such a complete system of heating, ventilation and air conditioning is referred to as HVAC instead of air-conditioning.
Commercial Air Conditioners
At Chiller & Aircon we carry out professional services and repairs to all makes of Carrier Air Conditioners. We also stock and carry spares and parts for Carrier Aircons.
Optimizing your industrial air conditioning requires some planning - which integrates regular servicing or yiou can go onto our SLA - A Service Level Agreement that grants you real 'Peace of Mind' as part of the deal, as it includes air conditioner servicing and maintenance to keep it running smoothly and optimally, while still being on stand-by should an 'emergency' occur.
Commercial Air Conditioning
Chiller & Aircon offers a wide range of Industrial Air Conditioners for all purposes; from computer data centeres to running hospital theatres, from mining applications to office blocks.
As one of the leading industrial air conditioner manufacturers, Chiller & Aircon also carries parts and spares for as well services and maintains Trane Aircon equipment.
HVAC Systems for Computer Data Centres
Running a cool computer data centre is of vital importance and to some companies is a 'no compromise' situation. The selected rooms must remain at constant temperatures that are controlled by computerised temperature controllers.
We know and understand this situation all too well. Our CAREL Programmable Controls coupled with our selective commercial air conditioners - through consultation with you - gives you total control (with reports and stats) of your rooms temperature so that computers run efficiently and optimally.
Room Temperature Control
When room temperature becomes of the utmost importance, then having the right equipment and the right computerised humidity and temperature controls in place with top technical support becomes a very real investment.
What different types of air-conditioner are there?
Air-conditioning engineers broadly divide air-conditioning applications into comfort and process:
These aim to create an indoor environment that remains relatively constant in a range preferred by humans in spite of changes in outside weather conditions or in internal heat loads.
The types of air-conditioner used in comfort applications include:
These aim to provide a suitable environment for a commercial or industrial process being carried out, regardless of internal heat loads and external weather conditions. It is the needs of the process that determine conditions, not human preference.
Comfort applications for air-conditioners
With air-conditioning, deep plan buildings become feasible - otherwise they would need to be built narrower or with light wells so that the inner spaces receive enough outdoor air by means of natural ventilation.
Air-conditioning also allows buildings to be taller, since wind speed increases significantly with altitude. This makes natural ventilation impractical for very tall buildings.
Comfort applications are different for various building types, as follows:
Process Applications for Air-conditioning
These are many and varied. They include:
How does an air-conditioner work?
The air-conditioning process is a bit complex, but very basically it works in the same way as a refrigerator.
A compressor pumps refrigerant fluid through two coils. One gets hot and the other becomes cold. The warm air from the environment is taken into the compressor and blown over the cold coil to dry and cool it. This cool air is fed into the room to give it a refreshing feel.
Some warm room air is also drawn across the hot coil, to remove the heat from the coil. The hot air is then expelled from the unit through a window or a hole in the wall.
Air-Conditioners - (from 9 000 - 150 000 BTU)
We use the most popular and reliable brands, among which are:
Eco Air, Trane, Carrier, LG, Samsung, Daikin and York.
What are the main components of an air-conditioning system?
In the most common kind of air-conditioning, a pump transfers heat from a lower temperature heat source into a higher temperature heat sink.
The main components of the refrigeration cycle used in air-conditioning are:
- Evaporator coil
- Condensing coil
Air-conditioners use a compressor to cause pressure changes between two compartments. The compressor pumps the refrigerant fluid into the cooled compartment (the evaporator coil), where the low pressure causes the refrigerant to evaporate into a gas, taking heat with it.
In the other compartment (the condenser), the refrigerant gas is compressed and forced through another heat exchange coil. This condenses the gas into a liquid and rejects the heat previously absorbed from the cooled space.
Upgrading Your Industrial Air Conditioner
In need of greater efficiency or longer lifespan? Making use of your good old equipment for a while longer may make perfect sense - if done correctly. Industrial air conditioning serves a purpose and needs to be serviced and maintained on a regular basis in order to get the most out of each unit. Extending the lifespan - and saving budget can be done by upgrading your air conditioner and adding a programmable controller to it.
When upgrading your air conditioning system, you not only are investing in a longer lifespan of your unit, you are running more efficiently - which over time gives you a greater ROI - return on your investment.
