Typical Cooling Considerations

Air-Cooled• Length and size of hose needed for waterconnections?

• What is the system pressure?

• Will a pump be needed?

• Will air duct connections be needed to assistcondenser discharge?

• Routing?

Water-Cooled• If system pumps are used; will chiller be onpositive pressure side?

• Will a cooling tower be needed?

• Refrigerant Relief Routing (if in the building)

Questions to Answer• Available voltage?

• Total amperage?

• Available panels?

• Utility limitations?

• Impact on rates such as demand charges?

Typical Power Considerations

Typical Location Considerations

Questions to Answer• What effect will it have on traffic and pedestrians?

• Are permits required?

• How accessible will it be for maintenance?

• Will rigging be needed?

• Does the location cause any safety concerns?

• What will the public perception be?

• How secure will it be?

• Will there be noise and/or emissions problem?

Contingency Planning During Design

Typical Design Considerations

• Sizing of Plant vs. Redundancy

• Future Load

• Cost of redundancy today

• Emergency Piping Connections

• Emergency Power Connections

• Location

• Impact on typical hospital functions?

• Structural requirements
