The middle layer is plywood with an additional 10mm thick plasterboard on both sides, adding 20mm to the overall wall thickness. Plywood Walls: 120 millimetres Plywood Ceiling: 150 millimetres Shifting ammonia between gas and liquid using pressure (Chilled air is -22°C; chilled water is 0.2°C -0.5°C, cooling plates -25°C.)

Collect Data: Review the Technical Specifications Document for details like storage room dimensions, wall thickness, and materials. Use the ASHRAE CLIMATIC DESIGN CONDITIONS to collect local data. 2. Calculate Room Surface Area: Determine the total surface area of the storage room, accounting for walls and ceiling. Assume that the floor is well insulated and that heat transfer within the floor is negligible. 3. Assess Insulation: Evaluate the insulation thickness and material properties. 4. Calculate Heat and Ventilation Loads: In general, heat load calculations consist of several components such as equipment and internal and external sources. In this project, it is crucial to consider lighting as part of the heat load, in addition to the ventilation load. The other factors can also be taken into account, however, those are optional considerations. For lighting load, see Appendix A. 5. Determine Heat Transfer Coefficients: The convection heat transfer coefficients for internal surfaces and external surfaces are 8 W/m² K and 30 W/m² K, respectively. 6. Conduct Heat Loss Calculation: Use the temperature difference between indoor and outdoor environments, surface area, and heat transfer coefficients. 7. Analyse Results: Evaluate the heat loss calculation and cooling capacity assessment findings. 8. Prepare Report: Create a report with calculations and recommendations for insulation and air conditioning requirements to maintain desired storage room temperatures, including drawings, diagrams, and specifications.
