AUTOMATIC OPERATION CONTROLLING SYSTEM FOR PLANT CULTIVATION GREENHOUSE

摘要

PPROBLEM TO BE SOLVED: To provide an automatic operation controlling system suppressing excess and deficiency of a heat quantity necessary for cultivating plants in a greenhouse, and increasing heat efficiency of a cogeneration facility. PSOLUTION: This automatic operation controlling system has a cogeneration facility 1 which generates heat and electric power using gas fuel, and a heat storage tank 12 which heats a medium 7 in a greenhouse 2 to a temperature suitable for cultivating a plant 6 using heat and electric power generated by the cogeneration facility 1. The operation of the heat storage tank 12 is controlled with a computer 3. The computer 3 predicts a heat quantity in a fixed time, necessary for the heat storage tank 12, based on weather forecast data obtained from the Internet 20, and controls a heat storage temperature, a heat storage time, and an electricity generating time so as to secure always and safely a heat quantity corresponding to the change of weather.
