SELECTION OF EQUIPMENT

Based on technical specifications, acceptable equipment is identified. The final selection is made on the same basis as in Selection of System. The decision tree is shown in Fig. 3.13.

Explanations of Fig. 3.13

Step I: Performance Characteristics

Define performance characteristics based on system selection.

Step 2: Alternative Equipment

Select alternative equipment for comparison.

Step 3: Selection of Acceptable Equipment

• Compare different equipment to performance characteristics.

• Accept equipment that fulfills the characteristics for further comparison.

• If no acceptable equipment exists, return to selection of system to reconsider system selection with available equipment.

Step 4: Feasibility Comparison of Acceptable Equipment

Calculate costs, consumption of goods (energy, electricity, etc.), and possi­ble heat recovery of acceptable systems.

Step 5; Selection of Equipment

Select the optimal equipment solution based on the comparison calcula­tions.

Step 6: Technical Specification for Selected Equipment

Develop a technical specification for selected equipment. The tools include:

• Computer programs

• Diagrams for manual use
