New roof absorber heating plant with digital energy management

New roof absorber elements have been developed and tested. In 1984 a bivalent heating plant with 500 squaremeters of roof absorber was put into operation. An automatic data aquisition enables a detailed control of the operating behaviour of single components as well as the survey of the control strategy. Furthermore, control strategies were developed which are transferable to other similar multivalent heating plants. (ISE)
