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.
