Solution. First, the initial costs for both options are estimated. For the conventional cooling plant with the electric chiller, the initial cost, ICconv is: I C c o n v = 2000 tons * $ 2500 ton = $ 5,000,000. For the DCS, the cost for the connection, ICDCS, is. I C D C S = 50 m * $ 3000 m = $ 150,000.
