Automatic power variable energy-saving heating with solar energy

Abstract

The invention relates to a power-variable energy-saving heater with solar energy, wherein it comprises: a solar-energy collector and energy-saving heater; the liquid outlet of collector via liquid outlet tube is connected to the liquid inlet of energy-saving heater; the liquid outlet of heater via liquid reflux tube is connected to the liquid inlet of collector; the liquid outlet tube is mounted with low-noise pump and liquid inlet valve; the liquid reflux tube is mounted with liquid outlet valve; the heater contains several parallel metal tubes; the metal tube contains heating core; the heating cores of several metal tubes are serially connected, whose two ends are connected to the power resource; the energy-saving heater contains liquid medium. Compared with present electric heater, the invention can save 70-80% energy; and compared with solar-energy heater, the saved energy can reach 40-60%.

Description

technical field [0001] The invention relates to an energy-saving heating system, in particular to an energy-saving heating system with self-variable power and solar energy. Background technique [0002] At present, the energy used for domestic heating in winter is mainly coal, liquid medium, natural gas or electric energy. Except electric energy is clean energy among these several energy sources, the rest will cause environmental pollution to human beings. The general electric heater consumes a lot of power, generally more than 750 watts, and more than 1800 watts. In addition, the heat dissipation area of ​​the electric heater is small. [0003] Although people have invented some solar heaters now, these heaters have considered the situation of cloudy days, nights or insufficient solar energy in winter, and have adopted a combination of solar energy and electric heating for heating, such as Chinese patents ZL02285239.5 and ZL02283944.5 Patents all disclose heaters that use...

Problems solved by technology

The general electric heater consumes a lot of power, generally more than 750 watts, and more can reach 1800 watts. In addition, the heat dissipation area of ​​the electric heater is small.

[0003] Although people have invented some solar heaters now, these heaters have considered the situation of cloudy days, nights or insufficient solar energy in winter, and have adopted a combination of solar energy and electric heating for heating, such as Chinese patents ZL02285239.5 and ZL02283944.5 The patents all disclose heaters that use solar energy and electric energy for heating, but these heaters consume the same amount of electricity as the general electric heaters when the solar energy is insufficient, although they are comparable to the general electric heaters. can save some energy, but still cannot meet the needs of indoor heating in winter
