The Purpose of Modular Units in Commercial Air Conditioning

Here in Bluffton, commercial air conditioning systems are a common sight among our offices and retail stores. They operate according to the same basic principles as residential air conditioning systems – cycling refrigerant gas through a series of valves and coils — but utilize different organizational methods to deliver it. Specifically, they use modular units, often placed on the rooftop, while most residences use just a single centralized unit. The purpose of modular units in commercial air conditioning goes a long way towards explaining these differences.

Every air conditioner in the world has a specific power load: the amount of cooling power it can generate. That power needs to be carefully balanced against the needs of the building to which the air conditioner is attached. If it’s not powerful enough, it won’t cool the air properly. If it’s too powerful, it will cycle on and off repeatedly, increasing strain far more than it should.

With residential homes, sizing isn’t usually a problem. The needs of the space remain more or less unchanged regardless of who’s living there, and as long as the system is properly sized, nothing more needs to be done. But commercial systems require a lot more flexibility. Occupants come and go as the needs of their business shift and new residents may have much different cooling needs than old ones. For instance, an office that has a huge amount of computers requires extensive cooling, while one that specializes in storage might need only a fraction of that cooling power.

Modular systems allow the building to adjust to those needs without replacing the entire system. If your cooling needs increase, you simply connect a new modular unit to the existing system. If your power needs drop, you can disconnect a single unit without disabling the rest of the system. It makes a lot of sense, both in practical terms and when looking at the bottom line for operating costs.
