The Seawater Greenhouse system uses sunlight; seawater and air to provide freshwater and cooled and humid air; so that in addition to provide the water required for greenhouse; supply more sustainable environmental condition from cultivation of crops in arid coastal regions. In this system ambient air is passed through the two evaporative cooling pads; which plant growth area is placed between those pads; by fans that placed end of the building; and then returned taking humidity on the tube-and-fin condenser. In order to decrease the entrance heating load to the plants; use pipe arrays to provide shade. This paper tries to describe simulation the Seawater Greenhouse considering condition of the Bandar Abbas City in IRAN. it shows that by increasing entrance air relative humidity; the water production and floor temperature increases and the differential temperature decreases. Also with increasing seawater flow rate; the water production increases and differential temperature and floor temperature decreases. With increasing entrance air flow rate; the water production water production and floor temperature decreases and differential temperature increases. Different cycle is developed and investigate in this paper and shows that in cycle that is water exist from first evaporator is passed under the greenhouse floor; is the effective cycle and produces more water than other cycle.
