1. Design a cold storage for 10 tonnes of apple. The temperature of apple at harvest is 20C. The atmospheric temperature outside the storage room is at 30C and the relative humidity is 60%. Polyurethane is used as insulation material. The cold storage is to be maintained at 4C. Assume the other required parameters. 1. Design a cold storage for 10 tonnes of apple.
