The Small District Heating Combisystem

摘要

The hydronic combisystems seen above are examples of a new standard that includes both a plumbing configuration and a control scheme. When taken together, this comes very close to becoming a plug-and-play solution for solar/hydronic combisystems that requires very littlecustomization from one system to the next.The piping diagrams seen here are put together in a systematic configuration that allows the same basic design features to be applied easily in both large and small hydronic combisystems. Multiple heat sources and multiple heat loads of various temperatures can be combined to work together with a minimum of customization from one heating job to the next. Since every heating system has the same basic configuration with the same basic control requirements, a standardized control system can be used on every heating job as well.The SLIC control is used to provide intelligent control for all three of the examples seen above. The same control box with identical hardware is used in every case, large and small, but with different software activated to match the heating equipment in each installation.A program is available on the solarlogic.com website that we use to guide our design of these standardized primary loop piping systems. It is called the SLASH/D (SolarLogic Assisted Solar Heating Design) and anyone with a computer and a web browser is welcome to use it for free.
