Office Depot will add Coolerado air conditioners to some of its stores, working in conjunction with existing, traditional HVAC systems.

In this configuration, the existing roof top units will run half as long as they would without the Coolerado units. This will translate to a 50 percent reduction in compressor run time, reducing electricity consumption, says Coolerado.

The Coolerado units are often able to hold the cooling set point of the building on their own, even during peak usage times, according to the company.

In addition to efficiency, the Coolerado units constantly introduce fresh air into the building. Coolerado units also allow for greater flexibility in maintenance scheduling and cost reduction in existing HVAC servicing and repairs.
