HEATING AND HOT WATER SUPPLY SYSTEM USING SOLAR COLLECTOR FOR VERANDA PARAPET

摘要

A heating and hot water supplying system using a solar heat collecting pipe for a veranda parapet is provided to install solar heat collecting pipes at a regular interval along a parapet of a building and to keep ventilation and a prospect between heat collecting units. A heating and hot water supplying system using a solar heat collecting pipe for a veranda parapet comprises a heat collecting unit(20) including a pipe shaped solar heat collecting pipe(21) installed at a veranda parapet, to heat water supplied from a water supply pipe(10) by collecting solar heat, and a heat storage tank(30) storing insulated warm water heated by the heat collecting unit. The heat collecting unit comprises a vacuum tube, a convection tube(21b) inserted inside the vacuum tube and filled with the water supplied from a water supply pipe, a first heat pipe(21d) inserted partly inside the convection tube, and a reflection plate surrounded around the vacuum tube, to heat the water filled inside the convection tube by collecting solar heat. The heat storage tank stores the water supplied from a water supply pipe, and includes a part of the first heat pipe, to exchange heat from heat transfer fluid to the water in the heat storage tank.
