| Résumé : | Optimization of the operating conditions and process scheme of an ammonia−water absorption refrigeration system, minimizing operating and annualized capital costs, is described. Various heat-exchanger technologies, the effect of the evaporator purge, and the thermodynamic restrictions of the system are taken into account. The objective is to make optimum use of various heat-exchange technologies to reduce the capital cost and meet the process refrigeration service requirements. A procedure to take account of the film coefficients and pressure drops of the different types of heat exchangers considered is proposed, which gives a solid basis for making decisions regarding the use of industrial ammonia−water absorption refrigeration. |
