kedelkredsløb

Kedelkredsløb is a Danish term that literally translates to "coil circulation" and is used in several technical contexts to describe a closed loop in which a fluid is circulated through a coil or serpentine heat exchanger to transfer heat or energy. There is no single universal definition; the exact meaning depends on the field (heating, process engineering, or thermal systems).

In heating, ventilation and air conditioning (HVAC) and boiler systems, kedelkredsløb usually refers to the closed circuit that transports hot fluid from a boiler or heat source to heat emitters such as radiators or radiant panels, and back to the boiler. The loop is typically driven by a pump and regulated by valves and thermostats to maintain a desired temperature and flow. The coil or serpentine arrangement increases the surface area for heat exchange between the circulating fluid and the surrounding medium.

In process engineering, kedelkredsløb can denote any coil-based heat transfer loop, for example a process stream circulated through a coil heat exchanger inside a tank, allowing efficient heat transfer with controlled mixing and temperature management. Design considerations include pressure drop, thermal expansion, corrosion resistance, pump power, and control strategies for stable operation.

Safety and maintenance aspects cover leak detection, proper sealing of steam and hot-water circuits, insulation to minimize energy losses, and routine inspection of coils to prevent fouling or corrosion. Because terminology varies, it is advisable to consult domain-specific sources when kedelkredsløb appears in technical documentation to confirm the intended meaning in that context.
