Tóm tắt
Model for energy and exergy analysis of absorption refrigeration using waste heat from textile factory has been built. The analysis that uses different models of heat exchangers are the overall heat conductance (UA) model, and the effectiveness model. The result show that the exergy loss in the generator and absorber are the larger than condenser and evaporator. Therefore, it is necessary to focus on improving these two important devices in absorption chiller. For the convenience of system operation, the research analyzed the effects of generator inlet temperature and solution pump mass flow rate on the energetic and exergetic performance of the absorption chiller. The study results indicated that the exergy efficiency of the absorption chiller decrease from 0.2776 to 0.2146 when increasing the solution pump mass flow rate from 1.5 kg/s to 2.5 kg/s and the generator inlet temperature from 80 oC to 98 oC. Meanwhile, energy efficiency will increase slightly initial from 0.769 to 0.779 and then decrease from 0.779 to 0.776 as the generator inlet temperature increases from 80 oC to 98 oC when solution mass flow rate is 1.5 kg/s. And energy efficiency decreases from 0.769 to 0.734 when the solution pump mass flow rate increase from 1.5 kg/s to 2.5 kg/sTài liệu tham khảo
