In most process cooling applications a pumping system circulates cool water or a water glycol solution from the chiller to the process. The process water is the means by which heat transfers from the process to the chiller. November 1 2017. Specific application considerations for absorption chillers are addressed in another trane publication absorption chiller system design sys am 13.

Centralised systems use chillers which are basically giant a c units but they work slightly differently because of their size. Refrigeration and air conditioning systems cover a wide variety of cooling applications using both standard and custom made equipments. This cool fluid removes heat from the process and the warm fluid returns to the chiller. The chilled water system is also called central air conditioning system.

Our chillers serve hvac systems that deliver the right temperature humidity and ventilation for the space but they also help minimize operating costs with superior energy efficiency levels low sound levels and with minimal environmental impact. Each building has its own unique set of conditions required to ensure the health comfort and productivity of its occupants. Refrigeration cycle moves heat from one space indoors to another outdoors refrigerant evaporates and condenses continuously within cycle refrigerant has a low boiling point making it ideal for hvac systems similar to car ac system.

All building need air conditioning. Some commonly used applications are process cooling by chilled water or brine ice plants cold stores freeze drying air conditioning systems etc. For smaller buildings this can be provided by a c units but once the building reaches a certain size it becomes cost effective to use a centralised system.
