Multi-split air conditioning units are excellent choices for commercial cooling. The units have multiple indoor air handlers that provide control over individual thermostats. Therefore, users can set their preferred indoor temperatures in the different rooms. As you invest in a multi-split AC unit for your building, note the following tips for overcoming cooling inefficiencies.

Size the air conditioner correctly

The key to optimal cooling in a commercial building is sizing your air conditioner correctly. If you get a small unit, it won't cool the building efficiently. Consequently, the air conditioner will work overtime to meet the cooling load, leading to frequent breakdowns and premature wear. 

An oversized unit will cool the space too quickly, leading to short cycling. The AC may even pull out all the moisture from the air, leading to low humidity problems. Size your AC correctly to ensure optimal cooling and efficiency. Below are three factors to consider when determining the right size for your commercial multi-split air conditioner.

Size of the building

Choose an air conditioner that can meet the cooling demands of your building. The bigger the building is, the larger the unit needed to cool it. Remember to account for ceiling height as well. Buildings with lower ceilings may require smaller ACs than those with higher ceilings. Your contractor can help calculate the square footage of the space to determine the best AC capacity for the building.

Number of occupants

Buildings with more occupants may have a higher cooling demand than those with fewer people. Human bodies emit some heat; therefore, the more the people in a room, the warmer the room will be. Therefore, the AC will work harder to keep the temperatures low. Thus, account for the maximum number of people that occupy the building, especially during peak hours.

Energy efficiency features

Does your building have insulation on the walls, ceilings, roof and floors? Are the windows double-glazed to prevent heat gain and loss? Buildings lose conditioned air through surfaces such as the walls, windows, ceilings, floors and roofing. If your building doesn't have insulation or window glazing, you need a larger air conditioner to maintain even temperatures. Conversely, an energy-efficient building endures minimal heat gain. Thus, you can get away with a smaller air conditioner.

Design practical zones

Proper zoning can prevent heat gain and hot spots in your building and increase the efficiency of your AC. Correct zoning also increases indoor comfort and prevents users from cranking up their thermostats. Therefore, work with a professional contractor to design your indoor zones. Invest in adequate indoor air handlers to ensure even cooling throughout the building.
