A humidification-dehumidification and vapor compression refrigeration (HDH-VCR) cycle has been integrated to meet the freshwater, space conditioning and hot water demands with the minimum floor space. In the refrigeration cycle and heat pump cycle, heat absorption and heat rejection are the desired outputs respectively. In the proposed HDH-VCR, a water-cooled condenser for humidification and an evaporator for dehumidification are simultaneously used to generate the desired outputs. Thermodynamic simulation and analysis have been focused on studying the effect of evaporator temperature, hot water temperature, atmospheric temperature, and atmospheric relative humidity (RH) on specific outputs, energy performance ratio (EPR), and exergy efficiency of the HDH-VCR unit. The objective of the current work is to maximize the EPR by optimizing the evaporator temperature. The resulted EPR at 50 °C of hot water temperature is 1.80 and 0.86 for cycle and plant respectively.

集成了加湿-除湿和蒸汽压缩制冷 (HDH-VCR) 循环，以最小的占地面积满足淡水、空间调节和热水需求。在制冷循环和热泵循环中，吸热和排热分别是所需的输出。在提议的 HDH-VCR 中，同时使用用于加湿的水冷冷凝器和用于除湿的蒸发器来产生所需的输出。热力学模拟和分析的重点是研究蒸发器温度、热水温度、大气温度和大气相对湿度 (RH) 对 HDH-VCR 装置的比输出、能效比 (EPR) 和火用效率的影响。当前工作的目标是通过优化蒸发器温度来最大化 EPR。在 50 °C 的热水温度下，循环和设备的 EPR 分别为 1.80 和 0.86。
