Investigation of The Heating of Greenhouses with solar Energy in The Province of Mersin

Abstract

These days, there are certain practical and financial challenges even if harnessing solar energy for greenhouse heating has become increasingly important. The initial investment cost of solar heating systems is proportionately higher than that of typical heating systems. The greenhouse absorbs solar radiation to partially meet its heat requirement during the day when the outside temperature is lower than the internal temperature. Within the natural energy sources that can be utilized to heat greenhouses, solar energy may be the most practical. In this study, this approach to greenhouse heating was investigated. The purpose of the study was to determine whether solar energy could be used to heat a two layers plastic greenhouse for 500 square meters in the province of Mersin. A thermal analysis of the planned greenhouse was also carried out. It is established that the plastic greenhouse needs a temperature of 1 °C outside and 15 °C inside. Additionally, CFD (Computational Fluid Dynamics) analysis was examined for the greenhouse model. Furthermore, during January, the coldest month, the average daily heating requirement for total daily heat was calculated to be 60 kW. It has been concluded that the plastic greenhouse should employ 51 mm diameter pipe that is 750 m long. It was concluded that the heat collection unit should employ 32 flat solar collectors in total, each with an absorber surface area of 1.8 m2.
