摘要
Although lithium bromide absorption chillers (LBACs) are widely used to provide thermal comfort by utilizing waste heat, they suffer from low efficiency. This paper presents an experimental investigation on a novel reformed LBAC based on the absorption principle of the lithium-bromide/water solution in the sub-steady equilibrium state that is, enhancing absorption pressure in the absorber and decreasing temperature in the generator of the novel LBAC. The novel LBAC results in the increment of double refrigeration capacity and the improvement of COP coefficient of performance (COP) by 1.5 times when the absorption pressure of the novel LBAC enhances from 1.2 kPa to 2.2 kPa.
