Abstract
Direct current power gained by photovoltaic cells can be used for heating water in a boiler. Simple installation allows use for domestic or industrial purposes, with a minimal impact to building construction. At the time of lack of sunlight intensity, water heating is provided by gas, or other heating source, or by use of a heating coil supplied by alternating current for that heating. When sunlight intensity is high, the photovoltaic cells of the present invention can be used alone. However, the source of the direct current has to be properly dimensioned in dependence on the volume of the boiler. An output 1 kWh of the source of the direct current gained by photovoltaic cells can be used to heat water of a volume of 100 L.
Claims5
A device for regulated water heating using energy derived from photovoltaic cells, the device comprising terminals (X1, X2, X3, X4, X5), where to the terminal (X1) an electrical ground (PE) is connected, which is then connected to a thermostat (T2), whereas to the terminal (X2) a line conductor (L) of the alternating current is connected, which is then connected to a normally closed contact (Y1) of a thermal fuse (TP) and then the line conductor (L) is connected to a normally closed contact of a thermostat (T2) and then the line conductor (L) is connected to a terminal (A1) of a coil of the contactor (ST), whereas to the terminal (X3) a neutral conductor (N) is connected, which is then connected to a normally closed contact (Y2) of the thermal fuse (TP) and than the neutral conductor (N) is connected to a terminal (A2) of the coil of the contactor (ST), whereas to the terminal (X5) a conductor (L+) of the direct current is connected, which is than connected to a terminal (1) of a switch of the contactor (ST) and than the conductor (L+) brought from a terminal (6) of a switch of the contactor (ST) is connected to an inlet terminal of a heating coil (R2), whereas to the terminal (X5) a conductor (L−) of the direct current is connected, which is then connected to a second inlet terminal of the heating coil (R2).
