FR2489942A3 - Roof mounted solar heating panel - has open bottom edge to vent interior to prevent misting of glass - Google Patents

Abstract

The solar heating panel is mounted on a roof and consists of a network of tubes (4) with a corrugated absorber panel (6). The enclosure is insulated below the absorber with a glass panel (1) covering the upper surface. The glass is supported on glazing bars (3). The top and side edges of the panel are sealed whereas the bottom edge is open. This arrangement prevents condensation on the inside of the glass panel and also permits the draining of any water which has leaked into the panel.

Description

 The present invention relates to flat solar collectors for producing hot water for sanitary purposes, heaters, swimming pools, etc.

 In existing solar collectors, a total seal is ensured by a seal between the inside and the outside of the collector. No air or water circulation is possible. In addition, in the case of an installation OR the sensor is an integral part of the roof, it is necessary to re-seal between the sensor and the roof of the roof. This usually requires the supply of additional parts.

 According to the invention, the waterproofing of the sensor with its support is ensured only on three sides: upper horizontal and vertical.

 The lower horizontal part does not have any seal which allows a slight circulation of air inside the sensor without altering its functioning; therefore condensation can flow through the lower part which keeps the glazing clean without fogging which filters the radiation and reduces the performance of the sensor.

 This evacuation becomes a security when during an accident the glazing allows rainwater to penetrate inside the sensor; the water flows through the lower part, filling the sensor with damage to the radiator and the insulation.

 According to the invention the banks have on three sides (upper horizontal and vertical) a gutter which collects rainwater from the entire surface of the sensor, it is discharged through the base part.

 To ensure a good seal when the sensor is integrated in a roof, it is enough to have the cover placed on the gutter with a good covering.

 Drawing 1/2 shows a general view of a sensor. The uprights (3) support the glazing (1) and the seal (8) which seals between the glass and the uprights. Two collectors (5) supported by the uprights ensure the arrival of cold water and the departure of hot water.

Pins (4) are connected to the collectors forming the radulator part. Absorbent plates (6) are elipsed on the pins, they are the ones that absorb the maximum radiation thanks to their cells, they heat up and transmit calories to The water flowing through these pins separates calories and is discharged into the collector set with hot water.

 To reduce losses from the rear part, a space is provided under the absorbent part for placing an insulating dobby.

 This sensor can be built in all dimensions and placed on all types. It solves the problem of the size of the sensor and the space available on the roof.

 This Custom Model is particularly interesting in the case of a layout where the aesthetic is subject to the propertions: height width.

 Due to its simple construction and the large number of elements dismantled tablesil can be sold in "Kit" lowering the cost of usual solar installations.

Claims (3)

1.Plane solar collector characterized by the fact that it comprises on the upper part and the lateral faces a flow channel which collects rainwater falling on its external face and on the upper part of the roof and discharges it by the lower part of the sensor. 2. Planar solar collector according to claim 1 characterized in that it peddles aeration for the evacuation of condensation and accidental oil. 3. Planar solar collector according to claim 1 characterized in that the absorbent plates are connected to the radiator by clipping projecting widely on the lower part of the pipes.
