溴化锂制冷技术为国家能源部推广的节能技术,它是以蒸汽或热水为动力,制取0℃以上的冷水。特别是RXZ系列热水型溴化锂制冷机是以85℃的热水为动力,可以充分利用化工行业的余热。我厂针对氯碱装置的蒸发工序、盐酸工序和浸没蒸发装置均有大量可以回收利用的废热,于1992年上了一套RXZ-350热水型溴化锂制冷装置, 相似文献

Modeling studies have been carried out to investigate coupling of an solid oxide fuel cell auxiliary power unit (SOFC APU) with a small scale NH3–H2O based vapour absorption refrigeration system (VARS) for a refrigerated truck/trailer application, by using hot cathode exhaust from the SOFC stack to drive the VARS. A bottom up design and modeling approach has been adopted where the end requirements, cooling load in this case, are identified first followed by upstream modeling of the SOFC and VARS unit. This approach enables design of system/components to meet the desired end requirements rather than compromise or fall short of the desired goal. Initial modeling results show that it is indeed possible to couple an SOFC with a VARS on a small scale (< 10 kW cooling load) for the refrigerated truck application. As this novel strategy utilizes both heat and power from the SOFC it promises a higher total efficiency up to 80% and also removes a significant part of the load from the main diesel engine, thereby leaving the engine to carry out the task of only propelling the vehicle. The excess electrical power from the SOFC could also be used to charge the vehicle batteries. 相似文献

The main objective is to show the effect of the choice of the most adequate combination of activity‐fugacity coefficient models on the vapor‐liquid phase equilibrium (VLE) data quality and on the calculation of the enthalpies of the different vapor and liquid streams in a refrigeration absorption machine. Six alkane binary mixtures, i.e. propane or n‐butane as refrigerants and n‐heptane, n‐octane, or n‐decane as absorbents, were considered as working fluids for their proven positive characteristics. Two activity coefficient models, UNIFAC and NRTL, and two equations of state, virial and Peng‐Robinson (PR), were tested. The obtained results showed that the UNIFAC‐PR combination reproduced the VLE data reasonably well; hence, it should be recommended for this type of refrigeration systems operating with alkanes. 相似文献
