Commercial Air Conditioning

Commercial air conditioning refers to the cooling, ventilation, and air conditioning systems that are designed and installed in commercial buildings such as offices, retail stores, hotels, hospitals, and other public spaces. These systems are typically larger and more complex than residential air conditioning systems, and are designed to meet the specific requirements of commercial buildings to ensure the comfort and well-being of the people inside, as well as to maintain optimal conditions for equipment and materials. Commercial air conditioning systems can vary in size, complexity, and type, depending on the size and usage of the building. 

See the different types of commercial air conditioning below:

VRV Air Conditioning Systems

Variable Refrigerant Volume systems are high-end type systems which provide advanced solutions for any large residential or commercial applications. In its simplest form a single VRV outdoor unit can be connected to multiple indoor units. This system offers significant improved efficiency by varying the flow of refrigerant to the indoor units based on the exact demands of the individual area. This system is very flexible, making it ideal for many types of buildings i.e Banks, Libraries, storage facilities, health care facilities, hotels, schools & larger residential homes.

Aesthetically, these systems also allow for multiple styles of indoor units, allowing you to choose the indoor unit’s design and functionality that suits your needs. The ability to use long pipe runs, so that the outdoor units can be in “out of the way” places is also an added benefit.  

Features of a VRF air conditioning system:-

  • Up to 64 indoor units connected to one outsider condenser unit, saving space & installation costs

  • Energy Efficient

  • Multiple styles of indoor units

  • Simultaneous heating and cooling options in various rooms

Roof Top Package Unit

These self-contained units are still the most popular used HVAC systems when it comes to commercial air conditioning. Where a split system is not practical to install or where a split system cannot provide the required capacity, the roof top packaged unit is still the unit of choice.

With a rooftop package unit, all the components are housed in one cabinet stored on the top of the building. Both sets of coils, to release and absorb heat, are in the cabinet along with the compressors and the fans. The unit connects directly into the building’s ventilation system to circulate the air.

Features of a split type air conditioning unit:

  • Ease of installation

  • Excellent efficiency

  • Visually less intrusive – compact structure

  • Easy maintenance

  • Inverter technology, offering you a 30% reduction in your energy costs.

  • Air quality improvement

Ventilation Systems

1. Fresh Air Supply Systems 
Mechanical ventilation systems are necessary if there is insufficient natural ventilation. Mechanical air can be introduced by means of a fan, which may be stand alone or via the air conditioning system. To move fresh air from outside to inside requires an air intake, an air filter, ducts & room diffusers.

To minimise energy use, fans should be sized and controlled to move only the amount of ventilated air (oxygen) required to reduce the CO2 levels in offices for a better work environment.

2. Extract Air Systems
 Extract air systems for Bathrooms & toilets are compulsory if there is insufficient natural ventilation.  Extraction fans are used to control excess humidity, remove unpleasant odours & create a cleaner and fresher space for users.  Furthermore, careful placement of an extraction fan will also create a higher air movement inside the toilet & bathroom that would help with drying up of wet floors more quickly and to some extent provide some cooling effect to the users, especially during hot and humid summer days. Selecting the correct exhaust fan will solve Bathroom & Toilet ventilation issues.

3. Kitchen Extraction and Make-Up Air Systems
In kitchens where industrial cooking takes place, such as restaurants and hotels, it is necessary to install ventilation & extraction systems to ensure that contaminated air is extracted & discharged in order to maintain not only the correct temperature for comfort, but also the necessary conditions for a healthy & a hygienic environment.  

To successfully achieve this objective it is necessary to install the correct ventilation system designed according to the kitchen workload, the number of staff, the cooking equipment that will be used, ease of maintenance & energy efficiency.

It is important to keep in mind that the correct sizing of the fans is critical & the placement of the duct & vent extremely important for the correct performance of the system. Where a need for excess exhaust capacity exists, a supply fan that can provide enough make-up air, essentially air that can replace exhausted air to maintain room pressure can be installed.

N.B. A good ventilation solution must fit the building in which it is installed & the chosen solution should meet the requirements put on it.

Multi Split Air -conditioning Systems

Multi Split Systems provide heating & cooling for multiple rooms with just a single outdoor unit connected to up to five indoor units. Not only can multiple indoor units be connected, but one can even have a variety of type of indoor units. With a Multi Split you can have different temperatures for every room. These systems are easy & flexible to install as well as being extremely cost effective as it runs with just one condensing unit.  Another advantage is that you can heat or cool each room independently versus the entire house.

Features of a multi split air conditioning system:-

  • Each unit can be operated independently

  • Ease of installation

  • A variety of indoor units to suit your individual style and performance

  • Space saving

  • Heating & cooling
