Termodinamica S.p.A., Verona / Italy COVER THERMODYNAMIC MONOBLOCK BOILER

The subject of the present invention is a thermodynamic monoblock boiler.

In the case of the boilers of the known type, the water is normally heated by various sources of energy, including electrical ones Can consist of electricity, fuel or solar energy

In the case of electric heating, there are operating costs exceptionally high, while with fuels, their operating costs are lower, there are disadvantages due to pollution of the atmosphere and considerable maintenance costs

Finally, the solar energy, concentrated and accumulated by solar collectors, brings, although it is completely free is delivered, the disadvantages of skipping and insufficient in the winter months with it and can therefore can only be used to integrate other energy sources »

The various above-mentioned disadvantages of the boilers of the known type are alleviated by the boiler according to the present invention eliminated, which through the use of a heat pump as heat sources air (especially wind), rainwater and Taking advantage of solar radiation · More precisely, the subject of the present invention is a boiler, which thereby is characterized as being a vapor compression heat pump contains whose vaporizer consists of a number of

Is made of finned tube batteries, which the air (in particular exposed to wind), rain and sunlight while the condenser is in the tank of the water to be heated. · · * The accompanying drawing shows in a single representation the boiler as the subject of the present invention in vertical cross section.

Referring to the drawing, it can be seen that the Boiler consists of a container (i) in which the tank (2) for the water to be heated (not indicated) is located. A feed pipe (4) is connected to this tank (2) at the bottom and a discharge pipe (5) at the top, and accordingly for the inflow of cold water and the outflow of hot water. This tank (2) is through a thermal insulating layer * isolated from the container and inside, lying in the water is the condenser (3) of the heat pump with vapor compression · This heat pump, whose entire parts are interconnected by a closed circuit (7) of the known type (simplicity only indicated for the sake of the illustration), also contains the compressor (8) (preferably at low speed ongoing) and the expansion valve (9) »which are located in the container, as well as the static finned tube batteries (10), which form the evaporator »

The mentioned: static batteries have no insulation and are painted with selective varnishes of black color. You have advantageous in relation to the secondary super-
