Commercial Air Conditioning is the cooling, heating and dehumidifying of air in a variety of commercial and public buildings and spaces. This includes offices, hospitals, restaurants, shops and other retail properties. It is also used to keep cold and frozen storage facilities cool and is important for sectors like food and pharmaceuticals. Air conditioning systems provide a comfortable environment for staff and customers, increase productivity and improve the efficiency of businesses and buildings.
A commercial air conditioning system works in a similar way to commercial refrigeration, taking advantage of a natural scientific process. It takes a liquid and turns it into gas, which absorbs heat from the surrounding air. The refrigerant is then turned back into a liquid and the cycle repeated over again. This process is repeated, absorbing and expulsion air until the temperature of the room is optimum.
When choosing a commercial air conditioning system, there are several options to consider. These include multi-split, single-split, VRF or VRV systems. Multi-split commercial air conditioning systems have multiple indoor units connected to a single outdoor unit. This saves external space and allows for easier installation in larger buildings with many walls or rooms. This type of system is popular with offices and restaurants.
Single-split commercial air conditioning systems have a single evaporator and compressor which can be installed in smaller businesses, such as a boutique. This option is often cheaper to purchase and install and can save on energy costs.
Alternatively, VRF (variable refrigerant flow) or VRV commercial air conditioning systems have one outdoor unit with multiple indoor units. This means that they require more maintenance and upkeep than multi-split systems, but can be a good investment for large property owners as they allow for the most flexibility in interior layout.
A commercial air conditioning system needs to be more powerful than a residential system because it is designed to cool larger buildings with many rooms. The components in a commercial system such as the thermostat, compressors, fans, evaporators and blowers are much bigger. They also have to be able to run at higher temperatures because of the high demand on the system from the heating and cooling demands of the building.
In order to meet the energy requirements of a building, the best commercial air conditioning system will have an SEER or Energy Efficiency Ratio rating above 14.3 and an EER or Energy Efficiency Rating above 12.2. In Southwest regions like Arizona, both ratings are crucial.
A commercial air conditioner can be located in a garage or basement, a plant room or on the roof depending on the size and design of the system. A rooftop unit will have the most protection from weather, is easy to access and gives good noise control.
