Chiller Rooms & Refrigerant System

Refrigerant systems and chiller rooms play an important role in ensuring building operate comfortably. The process is relatively simple: chemicals (sometimes gases) are used to remove heat, creating cooler water and air. This is done through condensers, turbo air conditioners and coolers, and other refrigeration devices. Refrigeration systems and chiller rooms are necessary when building environments such as freezers, cold storage rooms, A/C rooms are present.
