Definitions

  • the present finding relates essentially to thermal installations for the utilization of solar power.
  • the main object of the present invention is to reduce to a minimum the need of maintenance of the solar installations.
  • the installation of the solar boiler has a circuit for the recovery of the thermal carrier fluid which is discharged under overpressure and/or high-temperature conditions, and for the following inlet into the system again as such conditions assume the normal operation values.
  • the thermal carrier fluid expands until the limits allowed by the safety devices 23 of the known type, such as an expansion tank.
  • the fluid is discharged from the safety valve 13, however, it does not go lost but recovered by a suitable collecting device into a suitable vessel 17.
  • Said thermal carrier fluid the composition of which is unchanged (for example, a water/glycol mixture) is then recovered from the above vessel 17 for its inlet into the solar circuit again.
  • the fluid crosses an automatic loading assembly which acts as a pressure regulation means 22 allowing the previously discharged thermal carrier fluid to be reintegrated into the circuit, thus keeping the predetermined pressure unchanged.
  • check means of the minimum level of the thermal carrier fluid (reached only in extraordinary events) inside the collecting vessel 17.
  • said check means includes a couple of level probes 27 (forming an electric circuit closed by the water/glycol solution as electrolyte), a minimum-level detector 28 and sound and/or light signalling means 29 in order to allow the manual inlet of the fluid into the circuit again.
  • a solar boiler provided with the automatic recovery of the thermal carrier fluid disclosed above includes the following components (fig. 1):
  • the solar boiler disclosed above can be installed both at the inside and outside.
  • the assembling of the whole hydraulic components of the integration parts consisting of boiler or heat pump, solar circuit, power supply and water distribution is made in factory. This allows all tests necessary to guarantee the full operation of the system to be carried out.
  • the installation of the finding is extremely easy: it is sufficient to connect the water pipes, the pipes of the solar circuit and the boiler integration circuit to the different manifolds located on the outside walls of the disclosed device to make up the boiler.
  • a further advantage of the present finding is to avoid any mistake during the installation and to reduce cost and time.
  • the boiler is provided with means including an automatic loading circuit which allows the thermal carrier liquid discharged by the safety valve of the solar circuit during the maximum expansion step to be recovered, thus ensuring the full operation of the solar power system and its capability of matching the different operation conditions over time.
  • the control panel with electronic exchange for the automatic control of the whole system sends drive signals to the solar circuit and the boiler according to the signals received from the several temperature probes located at different heights inside the boiler.
  • the finding disclosed above can be produced and assembled according to a wide range of size: for example, from a small-size model comprising an accumulation tank of 200 litres designed for a two-solar-panel system to a large-size model comprising an accumulation tank of 5000 litres designed for a fifty-solar-panel system.
  • a simplified variation of the finding (fig. 2) providing the same advantages disclosed above and to be applied to the already existing solar boilers includes means for the collection of the thermal carrier fluid in case of overpressure and/or high temperatures, and means for the automatic filling of the solar circuit as the pressure and/or temperature conditions assume the normal operation values again.
  • said simplified variation consists essentially of the automatic collection and filling assembly comprising expansion liquid manifold 15, filling vessel 17, autoclave 19, electronic regulation means for motor-driven pump 20, pressure gauge 21, automatic loading assembly 22, and minimum-level detecting and signalling devices 27, 28 and 29, respectively.
  • the simplified variation can be effectively used without essential modifications and with the same advantages disclosed above in all solar installations in which a thermal carrier fluid is used.
