THEORETICAL OVERALL ENERGY BALANCE IN A GREENHOUSE FOR FLOWERS

Abstract

The meteorological factors participate in the formation of the energetic balance influencing the exchange of heat and air circulation in greenhouses. Building type, orientation, size and location of the greenhouses are obviously conditioned by weather elements. Exists a close connection between the action of internal and external climatic factors in the construction of greenhouses, with many implications for economic, technological and biological, to be considered in drafting greenhouses and specialized studies. To calculate the overall balance should take into account the heating balance, the radiative balance and the energy required to sweat, evaporation, the sensible heat of air and soil as well as the stored energy in the process of formation of assimilates through photosynthesis.
