OPERATION OF FULL-CONTROL TYPE PLANT CULTIVATION CHAMBER

摘要

PURPOSE:To make up a cultivation system of high economical effect by changing the irradiation time zone for artificial light so as to be opposite to the normal pattern to reduce both the capacities of the cooling and heating of an air conditioner. CONSTITUTION:In an artificial light irradiation system for the title cultivation chamber, a time zone where the temperature of the cultivation chamber reaches a maximum due to outdoor sunlight is made a non-irradiation time zone for the artificial light for the photosynthesis of a plant, while a second time zone where the above temperature reaches a minimum is made an irradiation time zone for the artificial light.
