Abstract
The reuse of exhaust energy from internal combustion engines (ICE) in absorption refrigeration cycles has been the focus of several studies, it is estimated that for water cooled engines about 35% of the energy for ICE is lost through of exhaust gases. This makes the reuse of the energy emitted by these gases become a viable alternative for the non-use cycle of absorption of the engine cooling system. Previous studies have shown that mass flow control is derived from the exhaust gas for the absorption cycle is a good way to improve the Coefficient of Performance (COP) of this type of refrigeration cycle. This article experimentally evaluates an influence of the ambient temperature on the coefficient of performance of a refrigerator operating in a single pressure absorption refrigeration cycle and evaluates as limitations imposed by the ambient temperature.
