The use of latent heat to greenhouse heating in winter days is an important issue. The storage of the excess heat in greenhouses for sunny days in cold season is necessary with the increasingly up of the fossil fuel cost.

The use of solar energy for heating greenhouses in the cold period for a Mediterranean climate is an important issue. In this paper, the thermal performance of a new solar air heater using a packed bed of spherical capsules with the latent heat storage system in east–west oriented greenhouse,...

An experimental study was conducted to evaluate the thermal performance of a new solar air heater collector using a packed bed of spherical capsules with a latent heat storage system. Using both first and second law of thermodynamics, the energetic and exegetic daily efficiencies were calculated...

GSHP (Ground source heat pump) system is a promising technology for cooling and heating building in the world. Regrettably, this technology is still not available in Tunisia and it is time to test the GSHP systems in our country. For this purpose, two experimental systems are performed at the...
