HYDRONIC/BIPHASIC RADIATOR WITH REDUCED THERMAL INERTIA AND LOW ENVIRONMENTAL IMPACT

摘要

A radiator with reduced thermal inertia, based on the principle of phase changing, using a non-toxic, non-flammable fluid with reduced environmental impact. The radiator is provided by means of vertical pipes which engage a collector containing a pipe bundle-type exchanger with smooth or finned pipes, internally crossed by the thermo-vector fluid of the system, and which heat the intermediate vector fluid, bringing it to the biphasic state. The vector fluid evaporates, rising up the vertical pipes, flowing through the channels obtained in the extruded profiles of the vertical pipes themselves. The fluid re-descends, condensing on the walls, returning into contact with the hot pipes of the exchanger in order to re-evaporate and rise back up the vertical pipes. The film of condensed liquid provides the required heat exchange. The terminal is further equipped with mechanical parts which allow the inserting of temperature sensors for possible monitoring and control of consumption and system operation and control thereof, by means of on-board electronic control devices (electric valves) and remote devices suitably operating in radio-frequency.

主权项

1. A radiator of the thermosiphon type, in particular for heating rooms, comprising a radiating body made of metal which comprises:
a tubular-shaped collector defining a longitudinal axis and situated in the bottom part of the radiator, and adapted to contain an intermediate vector fluid functioning in the biphasic state, a heat exchanger placed within the collector, consisting of one or more pipes which are parallel to the longitudinal axis of the collector and within which pipes a thermo-vector fluid from an external heating plant can flow, at least one pipe which is orthogonal to the longitudinal axis of the collector, containing therein one or more channels connected to the collector and communicating with the same, an adjustment system integrated within the radiator itself, in order to adjust the temperature of the intermediate vector fluid as a function of the thermal requirements of the room, a temperature sensor for measuring the temperature of the intermediate vector fluid in contact with the heat exchanger.
