Metal hydride air conditioning of the waste heat of automobile engine coolant driving
Aiming at developing metal hydride air-conditioning system driven by the waste heat of automobile engine coolant, the principle of metal hydride air-conditioning system was introduced and a hydride pair LaNi4.7Al0.3/LaNi5 was developed working at 363 K/303 K/283 K. the working cycle was described in detail. the values of characteristic parameters of the metal hydrides used in the system were also given.
Theoretic investigation of the solar refrigeration system based on metal hydrides
Based on the metal hydride heat pump's characteristics,a novel solar adsorption refrigeration system was presented.The models of energy conversion and exergy analysis were set up.The flow and working principles of system was introduced in detail.The exergy efficiency and the quantity about the exergy loss of the system were discussed based on an example.The results show that the system has a better energy-saving effect,and it is affected by the quantity of solar radiate energy mainly.The goal of the system's optimization is to increase the exergy efficiency of metal hydride heat pump,based on the quantity of solar radiate energy.The other orientation of the system's development is to use the system coupled with other solar energy technology.
Thermodynamics on the Carbochlorination of Titanium-bearing Ores
The equilibrium compositions of the multi-component, multi-phase and multi-reaction system of carbochlorination of titanium-bearing ores are calculated with HSC, a computational chemistry software. The thermodynamic equilibrium calculation of the reaction system shows that a complete conversion of titanium-bearing ores is feasible at a temperature near 200oC. At temperatures ranging from 800 to 1600oC, the products of the reaction system are all in gaseous phase. Thermodynamic analysis accords with the industrial practice. The simulated results provide reasonable scientific basis for improving suitable technological conditions of the carbochlorination reduction.
