Abstract
In this work, the emphasis is laid on the study of energy storage and the estimate of the energy density stored for use in the absorption machine in its simplest configuration. As a matter of fact, a simulation program is used to calculate the solution densities and the dynamic system storage in an absorption cycle phase. In times of discharge, the evaporator and the absorber are the only devices in the cycle to operate either in energy or in the upgrading refrigeration. Such a study allows us to select the cooling phase with three storage tanks. At the entrance of the evaporator and the absorber, both reservoirs contain the pure refrigerant and the weak solution already stored in the generation phase during an operating day (charging phase). At the output of the third absorber, the tank is empty. An amount of the refrigerant evaporated at low temperature in the evaporator, receiving an amount of heat QE, and is absorbed by the weak solution with the release of an amount of heat QA at an intermediate temperature. The rich solution is, then, stored in the third tank. At the end of cooling, when both tanks are empty, the third will be full in order to be used in the generating phase.
