Economy of replacing a refrigerant in a cooling system for preparing chilled water = Remplacement du frigorigene dans un systeme utilisé pour préparer de l'eau glacée : impact financierKulčar, Bojan ; Goričanec, Darko ; Krope, JurijDue to the negative impact of refrigerants containing Cl and Br on the ozone layer, these refrigerants are being replaced with refrigerants containing fluorine. The article describes the replacing of ... refrigerant R22 in a cooling system for preparing chilled water, used for cooling reactors producing phenol-formaldehyde resins. After analyzing the existing state and the capabilities of the cooling system, the refrigerant R22 was replaced with refrigerant R407C. For both refrigerants a calculation of the cooling system has been made, the results of which are given in the form of diagrams depending on the evaporation temperature of the refrigerant. Profitability evaluation of replacing a refrigerant was carried out using the method of the net present value (NPV), the coefficient of profitability and the period of time in which the investment is going to return itself. Also the calculations of the savings of electrical energy needed for the running of the compressors and the price of chilled water have been done, using the method of internal profitability level (IPL).Source: International journal of refrigeration = Revue internationale du froid. - ISSN 0140-7007 (Vol. 33, iss. 5, Aug. 2010, str. 989-994)Type of material - article, component partPublish date - 2010Language - englishCOBISS.SI-ID - 14472470
