In this study, the main objective of the present study is to investigate to the heating of greenhouse using ground-source heat pump. A new sample greenhouse has been installed. In the study latent heat storage tank inside the greenhouse was filled with the phase changing material and discharged at cold nights and in the days when heat pump was insufficient to benefit from its energy. Heating pipes installed horizontally inside the soil, the heat pump, a circulation pump, measuring devices and other auxiliary equipments were used in the experiments. The experiments were carried out during the heating season when the greenhouses need heating. As a result, the heat storing efficiency and the performance coefficient of the heat pump were found. It is also determined that it is convenient and useful to use soil based heat pump in heating greenhouses when the conditions of our country are considered.
