AI Technical Summary

Technical Problem

Existing thermal systems require the use of a pump for fluid circulation, which necessitates electricity and is undesirable.

Method used

A thermal system design that utilizes free convection and a unique pipe configuration to eliminate the need for a pump, incorporating a sub-portion of the main pipe rising above the last reservoir before descending to the heat exchanger, allowing fluid circulation without mechanical assistance.

Benefits of technology

Enables efficient fluid circulation and heat management without the need for a pump, utilizing free convection for both heating and cooling operations, thereby reducing energy consumption.

Abstract

THERMAL INSTALLATION The invention relates to a thermal installation (100) comprising solar units (102) with a tank (104) and heat pipes (106) with a transfer pipe (105) passing through each tank (104), a buffer tank (108), a heat exchanger (114) buried in the ground, a main pipe (112) comprising a first portion (112a) between the outlet of the tanks (104) and the heat exchanger (114) and a second portion (112b) connected between the heat exchanger (114) and the inlet of the tanks (104), a filling pipe (116) connected between the first portion (112a) and the buffer tank (108), a main valve (118) mounted on the first portion (112a) between the filling pipe (116) and the heat exchanger (114), and at the outlet of the tanks (104),The first section (112a) has a sub-section (112c) which rises above the last reservoir (104) before descending towards the filling pipe (116) and the heat exchanger (114).
