Refrigeration and air conditioning systems cover a wide variety of cooling applications using both standard and custom made equipments.

Hvac chiller system pdf.

Air conditioning two general types of air conditioning cooling refrigerant based. The process water is the means by which heat transfers from the process to the chiller. In most process cooling applications a pumping system circulates cool water or a water glycol solution from the chiller to the process. This cool fluid removes heat from the process and the warm fluid returns to the chiller.

This is because the chilled water system can be networked to have multiple cooling coils distributed through out a large or distributed buildings with the refrigeration equipment chiller placed at one base central location. Centralised systems use chillers which are basically giant a c units but they work slightly differently because of their size. Specific application considerations for absorption chillers are addressed in another trane publication absorption chiller system design sys am 13. 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.

Some commonly used applications are process cooling by chilled water or brine ice plants cold stores freeze drying air conditioning systems etc. University of colorado boulder co usa overview system description secondary hvac systems air distribution room diffusers and air terminals duct design fan characteristics air handling units water distribution cooling coils pipes and pumps primary hvac systems electric chillers. Each building has its own unique set of conditions required to ensure the health comfort and productivity of its occupants. All building need air conditioning.
