Abstract
A photovoltaic thermal collector is provided with: glasses disposed on both a sunlight receiving surface side and an opposite surface side thereto; a hot-water producing portion and a power generating portion. An olefinic rubber sealing member (A) is disposed on at least one surface side of a power generating element of the power generating portion, and an olefinic rubber sheet (B) including carbon black is disposed on an opposite surface side thereto. In addition, a resin pipe as a channel of the hot-water producing portion is made of cross-linked polyethylene or polybutene; the resin pipe is sandwiched in the olefinic rubber sheet (B); and the olefinic rubber sheet (B) is further disposed in a side portion of the resin pipe and in a gap between one resin pipe and another resin pipe.
Claims7
A photovoltaic thermal collector,
- wherein a photovoltaic module is provided with glasses on a front surface side and a back-surface side of the photovoltaic module, and comprises
- a hot-water producing portion and a power generating portion;
- an olefinic rubber sealing member (A) that is disposed on at least one surface side of a power generating element of the power generating portion;
- an olefinic rubber sheet (B) that comprises carbon black and is disposed on an opposite surface side of the power generating element;
- a resin pipe as a channel of the hot-water producing portion that is made of crosslinked polyethylene or polybutene, wherein the resin pipe has a top portion, a side portion and a bottom portion opposing the top portion;
- and
- the olefinic rubber sheet (B) is further disposed to surround the side portion of the resin pipe and in a gap between the resin pipe and an adjacent resin pipe,
- wherein the resin pipe is sandwiched in the olefinic rubber sheet (B) in a way that the olefinic rubber sheet (B) covers the side portion and exposes the top portion and the bottom portion of the resin pipe, and
- the resin pipe is disposed in a spiral shape with respect to one sheet of the photovoltaic thermal collector, and the top portion of the resin pipe is in physical contact with a back sheet of the power generating portion, and the bottom portion of the resin pipe is in physical contact with the glass on the back-surface side, wherein the back sheet is made of polymer material.
