An open type solar heating and hot water supplying device

Abstract

The invention relates to an open type solar heating and hot water supplying device, wherein a solar collector is combined with an electric or gas boiler. The open type solar heating and hot water supplying device includes the following: the solar collector for collecting solar energy and heating the recycling medium liquid; a heat storage box for heating water by heat transfer; an open type box body communicated with the heat storage box; a first check valve arranged at the entrance side of the open type box body; a recycling pipe arranged at the exist side of the open type box body; and a boiler, which is connected with the heat storage box, and heats the flow-in water for supplying water to a water heater or a heating device. In the invention, the prior water heated first by solar energy is heated for the second time by solar energy, thereby heat supply can be realized with a few fuel, heating cost can be saved, exhaust gas can be decreased, and environment pollution can be prevented.

Description

technical field [0001] The invention relates to a water supply device using solar heat, in particular to an open heating and water supply device using solar heat which can greatly save electric energy or fuel and is beneficial to environmental protection. Background technique [0002] In the heating and hot water supply systems that are commonly used now, the heating device that utilizes solar heat and the heating device that utilizes electric energy or fuel boilers are independent of each other. [0003] When the solar water heating device is used for heating and hot water supply, no fuel is used and no waste gas is discharged, so fuel costs can be reduced and environmental protection can be achieved. However, due to the limited heat change that solar heat can provide, solar water heating devices are only suitable for heating small houses or small spaces, and can only be used as hot water supply devices for large facilities. [0004] The electric energy or gas heating devi...

[0015] But, on the above-mentioned existing heating and hot water supply device 50, owing to be provided with the nitrogen box that is used for circulating heat medium liquid in the heat collector, filling tank, pressure pump and when the temperature of heat medium liquid is too high A blower cooling device for cooling the heat medium liquid, etc., therefore, the structure is complicated and the cost increases

[0016] Moreover, the above-mentioned No. 10-0245532 Korean Invention Patent "Solar Thermal Heating System" and No. 20-0165569 Korean Utility Model Patent "Supplementary Heating Device for Solar Thermal Hot Water Heating System" have no structure and function of the collector. Specific description is given, therefore, the additional effect due to the collector cannot be confirmed
