Excerpt from An Evaluation of Gas-and Electric-Powered Central Refrigeration Systems for Food Distribution Centers This study compares the costs of owning and operating the natural-gas-powered refrigeration system at the New Boston Food Market, Boston, Mass, with a hypothetical electric-powered system. Results showed that the gas-powered system had higher initial cost but lower annual ownership and operating cost than the electric-powered system.

Excerpt from A Study of Refrigeration Systems for Urban Food Distribution Centers The most economical choice was to have one central refrigeration system (situa tion II) for the entire complex. Second choice, costing percent more to install and percent more to own and Operate, was to use a central system in each of the four buildings (situation III). Least desirable was to have each firm buy its own individual refrigeration system (situation I). This would cost percent more to install and percent more to own and operate than the single central system, and it would not provide heating and air conditioning for offices.

Excerpt from Central Refrigeration System for a Proposed Food Distribution Center in Dallas, Texas: August 1973 The plant equipment would consist of two separate but interconnected compressor groups, six large condensing units, two large accumulators, and one large tank. This equipment would be served by a group of pumps, as well as by the necessary receivers, intercoolers, and sundry other equipment.

Excerpt from Refrigeration by Electric Power The original function of the central station was to produce electric power for lighting only, and later for lighting and.power purposes. If the lighting load is the only output of the plant a very high peak occurs in the load curve between the hours of six and ten P. M., when the lights are turned oh, as can be seen from.the curve in Figure I. With a view to making the plant pay as much as possible, electric curwent was soon sold, during the day, for power purposes. This was necessary as the company could not afford to allow the plant to remain idle the greater part of the time. Figure II shows a plant where day and lighting load is carried, but even then the peak of the curve occurs during the lighting period. Although the boilers can be forced to some extent to meet this peak load, yet the station 'must be designed to give this maximum output. The boilers and.machinery will, therefore, not be run at their full capacity during the rest of the day and since the boiler and engine losses, attendance, 011 and repairs, remain the same the plant Will be run at a much lower efficiency than during the lighting period.
