Summary

In refrigeration and power cycles processes the use of air as heatsink for condensing, when large quantities of water are not available, is a common practice and even more frequent. Although ambient air has the great advantage of being available everywhere and in unlimited quantity, it also has numerous disadvantages: highly variable temperatures, low exchange coefficients, need to use of large heat exchange surfaces and large air quantities. To limit these drawbacks, LU-VE has developed an innovative solution named EMERITUS. This technology has a fan-cooled exchanger on which two additional water cooling systems are used in sequence: treated water is sprayed onto the heat exchanger coil and the remaining non-evaporated is collected and used on to the adiabatic panel. This combination of the two techniques has positive effects on both the thermal capacity exchanged and the quantity of water consumed. The article describes the functional principle of the new EMERITUS and analyses a case study in which the running costs of a water chiller combined with EMERITUS are compared with other traditional solutions.
