An improved absorption generator for solar-thermal powered heat pumps -part 1- feasibility

摘要

Solar heated absorption chiller installations have been, typically, very expensive for their rating.. The need to keep the liquid flowing within the collectors as cool as possible to enhance collector thermal efficiency. conflicts with the need to operate the absorption. Chiller at a higher temperature. The compromise usually results in poor collector efficiency as well as a relatively poor specific chiller effect. The proposed vortex generator permits a heat pump to operate efficiently with relatively low temperature solar heated fluid, (70-80deg C). As a result, the collectors are cooler and much more efficient. In addition, the specific heat pumping capacity is about, 27 percent greater than conventional systems operating at the same reduced generator temperatures and, therefor, a smaller chiller is required. The economic consequences of these benefits will be presented in Part 2.
