Description

Low-energy-consumption house heating system based on solar energy Technical Field The utility model relates to the technical field of indoor temperature control of low-energy-consumption buildings, in particular to a solar-energy-based low-energy-consumption house heating system. Background Along with the rapid development of social economy and continuous progress of society, energy conservation has become social consensus, and the traditional heating system depends on fossil energy such as coal, exposes out the defects of huge energy consumption, serious pollution and the like, and has difficulty in meeting the requirements of time development. Among the many renewable energy sources, solar energy stands out from the remarkable advantages of wide sources, cleanliness, no pollution, sustainable supply and the like. Photovoltaic power generation technology is widely used in the field of construction in recent years as a clean and renewable energy utilization mode. Traditional photovoltaic power generation systems mainly convert solar energy into electric energy, and unutilized heat energy is often dissipated through a radiator or natural convection, so that the energy utilization efficiency is low. In order to improve the comprehensive energy efficiency of the photovoltaic power generation system, researchers have proposed a photovoltaic-thermal (PVT) technology, that is, integrating a heat exchanger on the back of a photovoltaic module, and using the generated heat energy for building heating or hot water supply. However, the conventional PVT system generally heats water by using heat energy and then directly transmits the heated water to a hot water tank for standby use as domestic hot water, so that the heat utilization efficiency is low, and a great amount of solar heat is wasted. Temperature control is a core factor for improving the comfort of indoor living environment, a geothermal system is a common means for controlling the indoor environment temperature, but a conventional geothermal system is realized by adopting an electric heating film, and larger electric energy is required to be consumed. Therefore, the applicant considers that for the areas with larger temperature difference in the morning and evening and indoor temperature control requirement at night, the PVT system can be utilized to obtain hot water, then the geothermal system is introduced, so that the solar energy is better utilized to realize the temperature control of the inside of the house, and the temperature control energy consumption of the house is reduced. Disclosure of utility model Aiming at the defects of the prior art, the utility model aims to provide the solar-based low-energy house heating system which can better utilize solar energy to realize the temperature control of the interior environment of a house and reduce the temperature control energy consumption of the house environment. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides a low energy consumption house heating system based on solar energy, includes installs the photovoltaic photo-thermal device outside, photovoltaic photo-thermal device includes a photovoltaic board, and photovoltaic board electric power output is connected to a battery, and photovoltaic board lower surface is provided with the water intermediate layer, the water intermediate layer relies on pipeline and a heat storage water tank to establish ties into heat storage circulation pipeline, is located heat storage water tank play water position in the heat storage circulation pipeline and is provided with first power pump, its characterized in that, heat storage water tank lower extreme still is provided with exothermic delivery port, exothermic delivery port connects out exothermic water pipe, exothermic water pipe coiling back and forth is arranged in the house floor and is received exothermic return water mouth on the heat storage water tank, installs the second power pump on the exothermic water pipe. Thus, the photovoltaic and thermal device can provide solar power generation for the storage battery and solar hot water for the heat storage water tank. Meanwhile, when the temperature control heating requirement exists in the house, the second power pump can be turned on, hot water in the heat storage water tank supplies heat for the floor of the house, the temperature of the internal environment of the house is raised, and the temperature control energy consumption of the house is reduced. Further, the heat storage water tank is externally connected with a domestic hot water pipeline. Thus, the heat storage water tank can simultaneously provide domestic hot water for households. Further, a water inlet pipe with a switch valve is further connected to a pipeline positioned between the first power pump and the water interlayer in the heat storage circulating pipeline, and the water inlet pipe is connected with a municipa
