Abstract

This paper presents a novel closed greenhouse architecture, based on the coupled tanks system, in connection with a heat pump. One tank is underground; the second one is outside. The tanks store an initial amount of water and can collect rainwater. Weather conditions produce differences between the two tanks temperatures. Therefore, heat pumps can operate efficiently, in most situations. Besides watering the crop, the water is in the same time energy accumulator (heat and cold) and energy transfer agent, on the earth—inside air—outside air route. This system is highly flexible regarding different weather conditions, and therefore practically difficult to optimize. The most suitable control solution is soft computing. A control rule protocol is sketched, issuing out of experiments performed on a scale model. This expert algorithm must answer to several, and sometimes contradictory constraints, on the energy and water management (water amounts and flows in the system, with regard to tanks’ temperatures and energy requirements of the greenhouse).
