Technical Feasibility Study of Geothermal Energy Use of Meshkinshahr Site for Greenhouse Heating

Among the most important factors for social, industrial and prosperity development is energy, and in particular, inexpensive energy. Therefore, applying energy management and surveying is considered as a part of requirements and needs for increased productivity of production factors. Greenhouse heating can be provided using different systems and various methods. This research was done on geothermal site of Meshkinshahr for greenhouse heating in 2014. The required heat load was calculated that was designed considering the influence and transfer of the heat through greenhouse cover (load loss). Typical thermal systems, including space heating systems and floor and platform heating systems were considered. The geothermal site of Meshkinshar has the heating capacity of at least 123 greenhouse units in the conditions of glass cover at interior temperature of 22 degrees Celsius and the peak load of 100%, which indicates the high potential of this region to provide heating needs of greenhouse products and reducing energy costs. In general, in this site, in terms of technical parameters of greenhouse number, floor and platform heating systems, the most suitable cover material was obtained as the double-layer polyethylene with internal temperature of 12 degrees Celsius with a peak load of 60%. Also, regarding the annual heat load factor, this coating material gained an acceptable ranking for the geothermal site of Meshkinshahr.
