对太阳能复合空调(A/C)和加湿除湿(HDH)海水淡化系统的性能进行了参数和经济研究。该系统与蓄热和辅助加热系统集成在一起，实现了稳定运行。研究了不同运行参数和设计参数下的淡水产率、淡水回收率、冷量、电耗、运行系数和系统经济性指标。结果表明：(1)辅助加热器的电耗随新风量的减小而减小，随着新风温度、新风湿度和采暖系统温差的增大而减小；(2)新风温度、新风湿度和采暖系统温差的增大增加了系统的淡水产量和回收率，提高了系统的制冷量和电耗。与基本空调系统的比较表明，该系统具有较高的产水量、制冷量、性能系数(COP)和较低的功率/电耗。成本分析表明，总运行成本的节省随着室外空气温度和室外湿度的增加而增加，随着整个供暖系统温差的增加而减少。(C)2015爱思唯尔B.V.保留所有权利。
Parametric and economic studies of the performance of a solar hybrid air conditioning (A/C) and humidification dehumidification (HDH) water desalination system are presented. The system is integrated with thermal storage and auxiliary heating systems for steady-state operation. Fresh water production rate, fresh water recovery, cooling capacity, electrical power consumption, coefficient of performance and system economical index are studied at different operating and design parameters. The results show that (i) the electrical consumption of the auxiliary heater decreases with decreasing outdoor air flow rate and increasing both of outdoor air temperature, outdoor air humidity and temperature difference across the heating system, (ii) the increase in outdoor air temperature, outdoor humidity and temperature difference across the heating system increase the fresh water production and recovery rates, cooling capacity and the electric power consumption of the proposed system. Comparison with a basic air conditioning system showed that the proposed system has higher water production, cooling capacity, coefficient of performance (COP) and lower power/electricity consumptions at hot and humid regions. A cost analysis reveals that the saving in the total operating cost increases with increasing outdoor air temperature, and outdoor humidity and decreases with increasing temperature difference across the heating system.
