Analyze the condensation process using both chillers. Provide operating temperatures and pressures entering each component shown in the diagram (at points 1, 2, 3, 4). Indicate which chiller should be chosen based on the economics. See below for details:
-Your work is replacing a chiller that is used as part of a distillation process that condenses methanol (boiling point = 65 °C). Your task is to select the most economical type of system. A conventional chiller will have a lower first cost and will have lower maintenance costs than one that involves enhanced heat transfer surfaces, but the chiller with enhanced surfaces will condense the same amount of alcohol with a lower energy consumption. Select the appropriate chiller by considering the net present value of both systems. That value will involve the first cost of the chiller, and the present value of the maintenance and energy costs. The chiller uses a standard vapor-compression refrigeration cycle with R-22 (see Figure 1). For…
