SU1506042A1 - Roof of solar energy-heated building - Google Patents

Abstract

The invention relates to construction and can be used in low-rise buildings and structures. The purpose of the invention is to improve performance. The roof includes supporting elements 8, a cornice, a solar collector 3, made in the form of a U-profile profile panel, glazing 6 and is equipped with a drainage channel located at the eaves with a gravity valve in the lower part. Each solar receiver is made with gutters 12 located along its vertical edges directed along the roof slope. The gutters 12 are communicated by means of the hole 13 with a cavity between the said panel and the glazing 6, and the lower ends of the gutters are connected with the drainage channel. The cavity between the panel and the glazing is divided by bead 16 into insulated compartments. 1 hp ff, 4 ill.

The invention relates to the construction of n can be used in low-rise buildings and structures.

The purpose of the invention is to increase the operational quality

The figure shows a slope with a solar collector; on ig. 2 is a section A-A in FIG. 1; on ig.Z - node I in figure 1; figure 4 - th node II on.

Kryppa 1 includes a solar energy collector 2, which contains a helium receiver 3 with a tubular heat exchanger 4, heat insulation 5, glazing 6, facing 15 and rafters 8 with bead 9 and bars 10, the side edges of the P receiver 3 bent upwards and placed under the glazing 6 Under the lower plane of the solar collector 20 3 drainage channels 12 with 13 holes are placed. The eaves of the sloping roof are made in the first section of the catchment box 14, in the lower part of which are located the gravitational valves 15 of the well-known construction Solar collector 2 contains beadings 16, which divide the cavity between the solar collector and the glazing into separate, isolated compartments, and the splash 17, 30, the overlapping junction of the glazing 6-i

The roof of the building with solar glare is made of materials used in construction: solar collector 3 and tubular heat exchanger A - from 35 black aluminum, galvanized steel, plastic; heat insulation 5 - from mineral wool, foam plastic, perlite; glazing 6 - from silicate glass; facing 7 - from metal -. 40 sheets or asbestos cement sheets, fibreboards; 8 rafters - made of wood or reinforced concrete; drainage box 14 - from aluminum or galvanized sheets, including 45 with thermal insulation. They mount the roof from factory shields about

The solar heating system of the building works in the following way Q

During the period of irradiation of the solar energy collector, the blackened surface is covered with a selective composition with high absorbing and low radiating capacity, the surface of the solar collector 3 is heated and, through a tubular heat exchanger 4, gives off heat to the coolant circulating in it, such as water or antifreeze.

Heated to a predetermined temperature, the coolant enters the heat accumulator or heating devices of known construction (not shown). The bead 16 divides the cavity between the solar collector 3 and the glazing 6 into separate insulated compartments that prevent air circulation in the cavity, thereby reducing heat loss solar energy collector

In case of damage to the glazing 6, rainwater entering the solar energy collector 2 through the openings 13 is diverted into the drainage channels 12, through which it flows into the water collection box 14 o When the water reaches a certain level, the gravity valve 15 is activated and the water is removed street, and valve 15 again;, “The presence of valve 15 ensures the removal of water from glazing 6 inside the solar energy collector 2 when it is damaged, and during normal operation prevents the blowing of outside air into others changes require cooling of the channels 12 and apertures 13 of the system located in the lower region of each compartment, so prosochrgesheys provided complete removal of water from any compartment, but is prevented air convection therebetween

Claims (1)

Invention Formula 1, the roof of the building with solar heating, including the supporting elements, the eaves, installed in a series of helio receivers, each of which is made in the form of a panel with vertical edges, and glazing, characterized in that, in order to improve performance, it is equipped located at the eaves drainage channel with a gravity valve in the lower part, and each solar receiver is made with grooves located along the vertical fins directed along the roof of the roof and communicated with the cavity between the panel and the glazing, and the lower ontsami - a drainage channel. 2, A roof according to claim 1, characterized in that it is provided with beadings dividing the cavity between the panel and the glazing into the isolated compartments. ./ / P . one ag.2 Phag.c Editor N.
