determine the heat loss and heat transfer requirements for an air conditioningsystem in a storage room.
Steps:1. Collect Data: Review the Technical Specifications Document for details like storage roomdimensions, wall thickness, and materials. Use the ASHRAE CLIMATIC DESIGN CONDITIONS tocollect 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 transferwithin the floor is negligible.3. Assess Insulation: Evaluate the insulation thickness and material properties.4. Calculate Heat and Ventilation Loads (Heat Loss Calculations): In general, heat loadcalculations include several components, such as internal equipment, lighting, and heat gainsfrom external sources. For this project, identify and quantify the main heat loads affecting therefrigeration system, focusing specifically on:• Heat gains from the outside environment (through walls, doors, and ceiling)•…
