Split Systems For Commercial Buildings: Are Inverter Systems Worth It?

Split system air conditioning is a reliable, cost-effective cooling solution for commercial buildings, and one that has numerous advantages over ducted air conditioning and evaporative coolers. However, some split systems are more suitable for commercial buildings than others, so choosing the right model for your business's needs is essential.

If you are looking for a new split system to service your office, storefront or commercial space, you may have heard of inverter split systems. 

What Are Inverter Split Systems?

All split systems rely on compressors, which are contained within the split system's outdoor unit. These compressors pressurise and depressurise the refrigerant liquid that runs through the system. The unique properties of refrigerant liquids cause them to heat up when they are subjected to high pressures and cool down in low-pressure conditions.

When refrigerant liquid passes through a split system's compressor, it is pressurised until it becomes a hot, semi-gaseous substance. This excess heat is expelled into the open air using the fans, and the rapidly cooling refrigerant is then piped to the system's indoor units. As the refrigerant depressurises and cools, it passes through the heat exchangers within the indoor unit(s), cooling the air inside your building.

In standard split systems, compressors run at a single, fixed speed at all times. This setup is effective, but it is not energy efficient. Because the compressor will always be running at full power, even when temperatures are only marginally above optimum, a significant amount of energy is wasted.

Inverter split systems solve this problem using a power inverter fitted with sophisticated microprocessors. This inverter automatically fine-tunes the amount of power the compressor receives. During peak building usage hours or particularly hot weather, the compressor is fully powered. On cooler days, the inverter limits compressor power, so it only uses the minimum amount of energy needed to keep temperatures stable.

Why Invest In An Inverter Split System?

While split systems with inverter technology are usually more expensive than non-inverter models, they can be well worth the extra investment. Here are three key advantages of choosing inverter split systems for commercial buildings:

Improved Energy Efficiency

Because inverter split systems automatically adjust their energy consumption, they use a lot less energy in the long-term than a standard system running at full power. In larger commercial buildings serviced by a multi-head split system, these energy savings can equate to thousands of dollars a year taken off your business's energy bills.

Quieter Operation

Keeping your building tolerably cool is vital for employee productivity, but so is keeping ambient noise levels to a minimum. The compressor is the loudest component in any split system and can be loud enough to be audible indoors.

Because inverter split systems can modulate compressor speed, they are much quieter than standard systems whenever they are not operating at full power. Lower noise levels can make your commercial building a more pleasant place to work, minimising audible distractions and letting your employees get on with the job.

Decreased Component Wear

Because inverter split systems do not keep their compressors running at full power at all times, their compressors tend to suffer from less mechanical wear and tear than compressors fitted to standard models. This means lower maintenance requirements and longer service life, making an inverter system a cheaper long-term investment.
