Chilled water air conditioning systems, more commonly known as ‘chillers’ are a great choice for large commercial spaces like hospitals and schools. If you own a commercial character and you’re thinking about your future cooling needs, chilled water systems should definitely be on top of your list.
In this blog post, we’ll take a look at some advantages and disadvantages of chilled water air conditioning systems so you can get the right cooling system for your commercial space.

Advantages

They Are Cost-Effective

Hands down, one of the greatest things about chilled water air conditioning systems is that they can reduce your energy costs by half, especially if they come with the latest high-efficiency equipment. Since water is known to be better at absorbing heat than air, chilled water systems are immediately better than air-cooled systems. additionally, water is quite cheap and abundant and you won’t need to use costly refrigerant lines to keep your space cool, so you’ll end up contributing to overall cost savings.

They Contribute to Indoor Air Quality

Air ducts keep indoor areas connected in a building and this can cause unpleasant odors and air pollutants to spread easily from one room to another. The great thing about these systems is that you have to install a separate air handling system in each air which prevents the spread of odors and pollutants. This leads to a meaningful improvement in indoor air quality.

They function at Much Quieter Levels

Another assistance is that they function at quieter levels than traditional air-cooling systems. This is particularly ideal for buildings with sensitive environments like hospitals and fancy restaurants where noise could be very distracting and unhealthy for the occupants.

Disadvantages

They Come with additional Maintenance Needs

Because chilled water systems utilize water to move heat, this may expose the water to various conditions that can rule to scaling. Scaling, if you weren’t aware, is basically where deposits get accumulated on metal which can ultimately rule to corrosion. Corrosion can considerably affect the efficiency of your system.
To prevent scaling, the water that’s used in these systems needs to be treated first to remove impurities that can rule to scaling. This method that you’ll have to take care of additional maintenance needs and their respective costs in addition.

They Aren’t Ideal for Places with Water Shortage

Needless to say, chilled water systems require a good amount of water to function. This method they aren’t ideal for areas where there’s continued water shortage. If your company pays water costs, you can expect these costs to rise when you install a chilled water system.

They Aren’t as Effective in Humidity

Another important thing to observe is that chilled water systems don’t work as effectively in humid environments. Higher levels of humidity rule to an increase in the wet-bulb temperature that indicates how efficiently water can absorb heat. This increase can consequence in lower comfort levels and increased operating costs.
If the levels of humidity get too high, the occupants may experience a cold and clammy feeling. Air-cooled systems work considerably better in humidity because they can extract moisture from air more efficiently.
