... s at 40°, 1 room at 45°, 19 rooms at 50°, and 5 rooms at 72°. In this report, specific data, material, designs, and evaluations have been developed to determine an efficient system for providing the refrigeration requirement in such food distribution centers. Weather data and electrical, labor, and material costs used in this report reflect those current in Chicago at the time this study was made.
