Abstract
Background and objectives:
In recent years, the problem of drinking water has caused concern in various areas. For over 50 years, various methods of water supply such as distillation, reverse osmosis and electrodialysis have been used. The disadvantages of these methods are the high cost and, more importantly, the environmental consequences of brine shedding. In the northern provinces of Iran, in many areas, relative humidity reaches more than 60 percent, and sometimes more than 80 percent. On hot days of the year, splits in these areas produce water by condensing air into the air. This water is often discharged without regard to its quantitative and qualitative management. Identifying new water resources will lead to use in various uses and protection of existing resources in order to sustainably manage water resources. Therefore, in this research, with a managerial approach, the quantitative, qualitative and economic potential of water produced from Gorgan coolers was studied as a new water source.Therefore, it is necessary to know the quantity and quality of this water for management and recognition as a source of unusual water to meet some of the needs.
Materials and methods:
Therefore, in this research, with the managerial approach, the quantitative and qualitative and economic potential of water produced from Gorgan coolers as a water source was investigated. In this study, Gorgan was divided into four main regions. In these areas, the quantitative and qualitative conditions of produced water, the effect of cooler power on the amount of water produced, and the influence of various parameters on the choice of cooler power to be purchased by users, were studied over a six-month period. Also, with the average power of 21,000Wh and the tariff of electricity consumption, the price of water produced was calculated.
Results:
The water obtained had a neutral acidity, low turbidity and alkalinity and hardness. The mean water produced was 25.5, 29.8 and 22.67 for split and 13.79, 18.13 and 13 liters per day for window coolers, respectively, in the first to third periods. The water produced in the double coolers was more than the window type. As the cooler power increased, the water produced in both types of cooler increased. Also, two factors of area covered by coolers and building insulation had the most influence on the choice of air conditioner.
Conclusion:
According to the results, Accumulation of cars and overcrowding does not uneffective the quality of produced water. In this city On average, a considerable amount of 3542 cubic meters of water is produced daily through condensate water coolers, which is also used for sensitive applications(such as washing the body and face and contact with the skin and eyes)due to its high quality. Applying some assumptions and considering 50% of the cost of consumed electricity, the cost of production per liter of water will be 3173 Rials, which is approximately 25% of the final cost per liter of market drinking waterAccording to the results of this research, by creating a network of water outlet aggregation of home air conditioners using a simple piping in apartments and towns and considering the storage source, a considerable volume of water can be Used for different purposes in each apartment or even different towns. Therefore, solutions such as forcing the creation of water collection networks for gas coolers for buildings under construction in cities with high relative humidity and creating sites for the use of water production devices from the atmosphere can be a good solution.
