  • the standard PV modules themselves are designed for a pressure not exceeding 50g / cm2.

  • Patent UA116607 C2 describes a method for constructing a building PVT panel as a rigid package: from a sheet of front light-transmitting material of any size (glass or transparent material, color for facade panels is possible) with fixed FE and a back rigid plate (cement-containing and magnesite plates: slate, fibrolite; metal and alloys, synthetic materials, glass), which transfers the rigidity of the rear side to the front side, by creating spacer walls (stiffeners) or spacer fastening posts, fixed with a sealant with high adhesion evenly over the entire surface of the front and back sides along the perimeter of each PV or groups FE (Fig.
  • the stiffeners can be formed directly from the back side material as 8 (Fig. 2) according to part I (Fig. 1). After bonding with the front light-transmitting side of the carrier PV (mainly - tempered glass "solar-glass"), the ribs stiffness turns into beams giving additional and greater rigidity, i.e. a beam structure is created, the rigidity of which depends on the thickness of the package and the total butt area of the spacer ribs-walls and spacer posts with the front and back sides, connected by a polymer-sealant with high adhesion into one whole.
  • the level of rigidity is dictated by the amount of pressure on the roof surface - by a person on a pitched roof or by a mechanism on a straight line.

  • the front side - glass with photocells encapsulated with EVA film acts as an absorber in the building air PVT heat exchanger, i.e. building PV panels are uncoated (non-glazed) air heat collectors, which are known to be less efficient than glazed
  • This application for the invention proposes the implementation of the method described in the prototype for obtaining glazed (or coated) PVT- and T-panels with high strength characteristics and efficiency. thermal efficiency.
  • the aim of the present invention is a method of manufacturing glazed (covered) building panels-heat exchangers with integrated PVs for straight and pitched roofs and facades of buildings of the required rigidity.
  • the technical result of the proposed implementation is the creation of covered (glazed) air PVT- and T-panels that can withstand heavy loads, namely, the weight of people and materials when they cover roofs and facades, as well as: a) a significant improvement in the characteristics of the thermal efficiency of PVT- panels of the prototype with glazing - the coefficient of specific heat transfer in a glazed PVT collector with increased strength is 3 times higher than that of a non-glazed one [2]; c) the maximum increase in the light transmission of the glazing, therefore, the increase in the electrical and thermal efficiency of PVT panels due to the strength characteristics; c) cheaper construction of air PVT- and T-panels.
  • Fig. 1 shows the essence of the glazing design: construction PVT panels of the prototype (part I) by adding additional glazing made of tempered glass "solar glass” 1 with the formation of a second cavity or part II and reinforcing polymer spacer posts 6, 7 - polyurethane, silicone or MS-polymer sealant with high adhesion and, if necessary, transparent.

  • the solution of installing the PV on top of the carrier surface 4 has two goals: 1) to increase the light absorption of the PV in comparison with the prototype and the variant of Fig. 1, by lamination with a thin film i.e. to increase both the thermal and electrical efficiency of part I in comparison with the prototype [3] without taking into account the effect of the coating; 2) significantly reduce the cost of the PV module, because instead of the expensive "solar-glass" bearing glass used as an absorber, cheap glasses with a high iron content or sheets of polymer or metal with insulation or other ones with better absorbing properties are used. In this case, the bearing surface can be perforated for uniform air flow from the upper cavity to the lower one and vice versa.
  • Figure 2 shows two heat dissipating cavities of the prototype (according to part I of Figs. 1, 3), it is obvious that in the variants of Figs. 1 and 3, the additional cavity II of the coating can be sealed or connected to both halves of the heat dissipating cavity of the prototype or divided as a cavity of the prototype , i.e. into the covering cavity II, it is necessary to split into two parts and insert, respectively, a continuous spacer wall similar to the first cavity.

Abstract

L'invention se rapporte au domaine de la construction écologique et, notamment, des structures de panneaux échangeurs de chaleur de construction de toitures pour des toits plats ou inclinés et des façades de bâtiments avec ou sans photo-éléments intégrés. L'invention concerne essentiellement un procédé de production de panneaux échangeurs de chaleur de construction vitrés (revêtus) avec des photo-éléments intégrés, qui sont destinés des toitures planes ou inclinées et des façades de bâtiments et possèdent une rigidité voulue, ainsi que la production de panneaux PVT et T à air vitrés (revêtus) pouvant supporter de grandes charges, notamment le poids de personnes et de matériaux lors du revêtement de toits et de façades avec ces derniers, et a également pour but la diminution des coûts de construction des panneaux PVT et T à air. On obtient une augmentation maximale de la transmission de lumière des vitrages, c'est à dire une augmentation de l'efficacité électrique et thermique des panneaux PVT grâce aux caractéristiques de solidité.
