There are many types of air-conditioning systems on the market that are specifically designed for commercial applications, and each one has its own unique advantages. Which one you should choose depends on your priorities and preferences.

For most business owners, cost savings along with performance are top of mind when it comes to choosing a climate control system. If you’re one of them, you should consider the split system air conditioner. It’s one of the most commonly used in commercial buildings due to its versatility, cost-efficiency and ease of installation. Read on to learn more about it, its types and applications as well as other important details to know before you invest in one for your home or commercial space.

About Split Air Conditioners

A split air conditioner is so named because it is “split” into two parts. Unlike a conventional packaged AC unit that contains all components, a split AC system has an indoor unit (aka cassette) and an outdoor unit.

The cassette of a split system air conditioner is where you’ll find the distribution and filter parts, while the external unit houses the compressor and condenser. The cassette and outdoor unit are linked via a refrigeration line composed of copper tubing as well as electric cabling.

The Benefits of Split System Air Conditioners

The benefits of split system air conditioner include:

1. Ease of Installation

If your property does not have ductwork installed, you won’t have to worry. The refrigerant line connection in split air conditioner systems eliminates the need for ductwork.

What’s more, there is no need to drill holes or do extensive construction like you would with a window-type air conditioner. They can be placed on any exterior wall.

2. Temperature Control

Some rooms need more cooling than others. For instance, a hotel bedroom would require less cooling power than the downstairs lobby. With a split system air conditioner, you can adjust the temperature of each individual unit to match each space’s specific needs. Many newer commercial models also allow you to control temperature settings remotely via an app.

Split AC systems come in standard “cool only” and reverse cycle. The latter means it can not just cool but also heat your property if needed.

3. Lower Energy Costs

According to the Department of Climate Change, Energy, the Environment and Water, HVAC systems make up 60% of the energy use of commercial properties. For this reason, choosing an energy-efficient air conditioner is critical to save on operational costs.

You may be able to save money on utility costs when you choose a split system air conditioner that has a good energy rating. Models with inverter technology are a good option, as they require much less power than older models to achieve the same or higher level of cooling.

Types of Split AC Systems

Split system air conditioners can be categorised into two main types.

Single Split System Air Conditioner

This system pairs one indoor unit with one outdoor unit, linked together via copper pipe. A single split system air conditioner is a one-room solution. While it’s not ideal for multi-room applications, such as offices and hotels, it works well for cooling server rooms, yoga studios and other small commercial spaces.

Multi-Split System Air Conditioner

This type of AC works similarly to single split systems, except you can hook up not just one but several cassettes to the outdoor unit. Each indoor unit has its own thermostat, allowing for individualised control of the temperature in different rooms.

Another advantage of a multi-split system air conditioner is its scalability. You can have several indoor units to cool individual rooms or climate zones within your building. As your business grows and you make additions to your property, such as new rooms, you can simply install additional indoor units.

Multi-split AC systems are best for large commercial properties. Some examples are shopping centres, hotels, data centers, warehouses, galleries and restaurants.

Cassette Options

Split system air conditioner cassettes are either wall-mounted or in-ceiling. The former comes in a wide range of colours and styles to complement a property’s décor.

If the goal is to make the AC’s indoor units as unobtrusive as possible, then in-ceiling cassettes are preferable. These are ideal if wall space is needed for other purposes. Generally, however, in-ceiling cassettes are more complicated to install and service. Call us to learn more or get a quote.

Limitations of Split AC Systems

While a split system air conditioner performs excellently when used to cool small commercial properties, you’ll likely need a more powerful solution for bigger spaces. For instance, variable refrigerant flow (VRF) systems are increasingly preferred by builders and business owners for halls, stadiums, warehouses and other large spaces. Other options include rooftop models and chillers.

However, it is difficult to determine the right size of commercial air conditioner if you don’t have the training and experience. If you plan on having a commercial air-conditioning system installed in your building, it’s best to reach out to professionals. They will help you choose an AC system that meets your property’s cooling requirements as well as install and service it correctly.
