Abstarct: Water is one of the most important biological elements in the universe. The water crisis is one of the most important and unknown problems. According to climate maps in Iran, more than 65% of the country is an arid and ultra-arid climate. But there are two humid climatic regions in the country, one in the southern islands of the country and the other in the northern regions of the country. In this dissertation, how to design and build a water production device from the humidity in the air and study it in Azadshahr city (one of the northern cities) and Paqaleh village (one of the northern villages) which are located in Golestan province. - I am. This device is designed and manufactured using refrigeration cycle and equipments such as: compressor, condenser, evaporator, fan, dimmer fan and thermostat. The refrigerant used in this device is R-134a gas. After investigations to produce water in this device, it has been observed that due to the air pressure in the city or village where the experiments were performed, changes in the air humidity occur. Also, in the experiments, the amount of water produced was measured by changing the technical speed that directs the moist air to the evaporator. Using solkane software, calculations were performed on the data to verify their accuracy. The ratio of water production intensity to energy consumption (GOR) of the device was between 0.2 to 0.3. This device can produce up to 12 liters of water per day in temperate and humid areas. Total water production in the temperate and humid and temperate zone with the minimum fan speed was the highest. With increasing temperature and increasing humidity, it is observed that the amount of water produced increases.
