Greenhouses heating with solar energy

Greenhouses are covered places which beside heating and cooling, every kind of technology can be used and it supplies economically fresh plant every season. The temperature in the greenhouse had to fixed for grown up plants, while the temperature reaches optimum level. For this reason the insulation of the greenhouses walls important to decrease the lost of heat. The best example of storing passive energy is Tromb wall. Heat transfer starts when the Tromb wall?s surface temperature different from the greenhouses temperature. Two different greenhouses tromb walls have been made two varied materials in the experiment. The first solar greenhouse?s Tromb wall was made with plaster which painted black, the second Tromb wall has included PCM (Micronal ®). In this study, a solar greenhouses prototype have been done as proposes which temperature rates stay about +12°C/+14°C especially in winter at Anadolu University and experiment datas have taken. A programme has developped which language?s Visual Basic, to arrange the greenhouses conditions and at the same time to calculate the essential heat. In the solar greenhouses have in mind to do heating the greenhosuses with property of latent heat storage which contains PCM. The solar greenhouses which includes Tromb wall with PCM has observed 3.7°C higher temperature then the other in the same times of the day. Vegetables and some mines have been dried in this solar greenhouses. It is observed the greenhouse can be use for drying in summer. It is estimated the cost of warming can be decrease with using tromb wall in greenhouses.
