Absorption systems for combined heat and power: the problem of part-load operation.

Author(s) : GROSSMAN G., RASSON J. E.

Summary

The objective of this work was to investigate and propose ways of ensuring internal compatibility under part-load operation in combined heat and power systems (CHP). In particular, the goal was to maximize the utilization of available waste heat under all conditions. A CHP system consisting of a microturbine and an absorption chiller was investigated, and operation under part load analysed. The addition of an auxiliary desorber (generator) to the absorption system makes it possible to maximize the waste heat utilization from the turbine, while the latter operates at part load and full cooling capacity is still required. The auxiliary desorber enables operation of the heat pump at overall capacities exceeding the nominal with little interference of the added backup heat with the waste heat. Simulation results for the system with auxiliary desorption are described.
