Abstarct: Drinking water has become a critical issue everywhere in the world, specially, in hot and dry areas such as the Middle East. Producing drinking water from sea requires significant amount of energy, reducing energy consumption or using other cycles’ waste heat, can be a key factor. This paper focuses on the building and simulation of a new desalination system baxsed on humidification-dehumidification method. The invention of this system is the direct connection between air flow, water and heat exchangers in both humidifier and dehumidifier. In this device the heat is delivered directly and extracted between heat exchangers and cycling air. This system combines a compression refrigeration cycle and humidification-dehumidification (HDH) desalination. HDH desalination systems can be driven by low grade and renewable energy resources. Compression refrigeration system and desalination was analyzed by EES software. This paper investigated the effect of different parameters such as, inlet salt water temperature, salt water mass flow and air flow on fresh water production. The graphs indicate that the ultimate production rate of this device is about 1 liter per hour. Moreover results show that the GOR of this system and the specific energy consumption are 0.9 and 1.1 kwh/L respectively.
