Solar Energy Model Goennebek. Development and Planning of a Self-Supporting Heating Plant for Greenhouses

摘要

The recovery, storage, and saving of energy in greenhouses by application of solar energy is investigated. Self-sufficiency is sought by making use of long-term storage of summer heat. A pilot installation is described consisting of a greenhouse with air collector, a medium-term accumulator, a long-term water heat storage tank and a 1500 m square plane collector field. Detailed construction plans and data on energy requirements and costs are given. Full independence from fossil fuels of the greenhouse and adjacent auction hall and office space is demonstrated. Control and programming is performed by a process computer. The highly efficient heat insulation system is credited for most of the success. The present installation requires only 40% of the energy needs of a regular double glass greenhouse.
