| Abstract | In heat-pump-driven liquid-desiccant (HPLD) air-conditioning systems, the release of condensing heat from the heat pump to the regenerator solution and exhaust air (i.e., capacity matching) is very important to maintain the dehumidification performance as well as the operational feasibility and stability of the system. Therefore, in this study, the capacity matching especially focusing on the release of extra condensing heat of the HPLD air-conditioning system is optimized in conjunction with the energy performance. With four design variables under the various outdoor air conditions, a multi-objective optimization is conducted to simultaneously maximize a system coefficient of performance and minimize a newly defined capacity matching index of extra condenser. Pareto front which is a set of optimum points is obtained using multi-objective genetic algorithm, and final optimum solutions are then determined and discussed based on a decision-making scenario. In conclusion, the system coefficient of performance is maximally increased by 24 % and the capacity matching index of extra condenser is maximally decreased by 55 %, compared with each initial value. |
