P.4.3.8 Absorption Heat transformer Study: nested helical coils and two shells


A heat transformer by absorption (AHT) is a thermal equipment, which contributes for the environmental sustainability. Its main purpose is to increase the thermal level through a thermodynamic cycle using residual or renewable sources. The CIICAp-UAEM studies different configurations about AHT since the year 2000 and, its attention focus is currently to develop smaller equipments with high efficiency, where the heat transfer area for every component is relevant. A compact AHT of 2 kW was designed and characterized with only two shells (low and high pressure) and their components were made with nested helical coils. Heat transfer coefficients for evaporator were determined considering several temperatures and mass flux rates.
