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...

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...

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,...

This paper presents an experimental analysis to investigate the performance of a novel mixed mode solar greenhouse dryer with forced convection which was used to dry red pepper and sultana grape. The drier consisted of a flat plate solar collector and a chapel-shaped greenhouse. The drying rate...

The design of a hot air solar generator for different uses has been simulated while investigating the flow induced by a hot disc placed at the entrance of the open ended vertical cylinder. Ambient air (Pr = 0.7) enters the bottom of the cylinder with constant velocity and temperature, and flows...
