Attachment 02_Schematic Concept Proposal 8280.pdf

This is a schematic diagram depicting a conceptual heating and cooling system integration proposal. The document is labeled as an incomplete draft for conceptual clarity and presents the technical architecture for connecting an existing pellet boiler system with dual thermal circuits.

The schematic illustrates a system comprising two primary components: KWS 1 and KWS 2, each integrated with corresponding puffer (buffer) tanks. The existing pellet boiler supplies heated water to the heating circuit through control valves (marked AB with manual controls M). The system incorporates two separate thermal circuits—a heating circuit (shown in red) and a cooling circuit (shown in blue)—which operate in parallel through the existing infrastructure. The heating circuit connects to the pellet boiler and distribution pumps, while the cooling circuit branches independently with its own pump and distribution system. Flow control is managed through multiple valve stations (labeled 1 and 2) positioned at the supply and return points. The integration allows the existing pellet boiler to feed into KWS 1's buffer tank, which then distributes thermal energy to both the heating and cooling circuits via regulation valves and manual shutoff controls. This dual-circuit configuration enables simultaneous operation of both thermal systems while maintaining separation through the buffer tank storage mechanism.
