Geothermal source smart home system

Abstract

The invention discloses a geothermal-source smart home system, which comprises a pumping well, a ground source heat pump unit, a refrigerating mechanism, a recharge well, a water storage tank and a flow monitoring mechanism. The ground source heat pump unit pumps underground constant-temperature water from the pumping well through a pipeline; the refrigerating mechanism comprises a fan coil, an air guide disc and a flow guide pipe; a water return pipe is connected to the recharge well; the water storage tank is communicated with a tap water source, a water outlet end of the flow guide pipe andthe recharge well; the flow monitoring mechanism comprises a controller, a first flow meter, a second flow meter, a third flow meter and a first control valve, and respective amount measuring of water extracted from an underground constant-temperature aquifer and recharged water is realized. The controller acquires measuring data of the first and second flow meters and controls the third flow meter and a first control valve to open to replenish water in the water storage tank into the underground constant-temperature aquifer when recharged water amount is smaller than pumped water amount. Therefore, comfort is improved, energy saving and environmental friendliness are realized, underground water resource balance is guaranteed, and risks of geologic structural collapse and the like causedby underground water resource deficiency can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a geothermal source smart home system. Background technique [0002] At present, "smog" has become a major environmental problem in our country, especially in winter "smog" is particularly serious, in which particulate matter emissions from coal-fired heating and vehicle exhaust emissions in winter are important causes of smog. For the emission of vehicle exhaust, a conventional number-limiting policy has been implemented to reduce the number of vehicles. At the same time, new energy vehicles are also being vigorously developed, which will gradually replace traditional gasoline vehicles. However, for the problem of burning coal for heating in winter, although Now we are also vigorously advocating coal-to-gas conversion, but the corresponding costs for residents have also increased. At the same time, although natural gas reduces pollution, it is a non-renewable resource, which ...

AI Technical Summary

Problems solved by technology

[0004] Shallow ground source heat pump technology: Shallow geothermal wells occupy a large area and their application is limited; the cold and heat loads are unbalanced in winter and summer, and the energy efficiency of the system is seriously attenuated

[0005] Direct exploitation of deep-layer geothermal water heating technology: it can only be used in areas with rich groundwater resources, and its application is limited; direct exploitation of groundwater is difficult to recharge, resulting in waste and pollution of groundwater resources, and long-term extraction Groundwater, with risks such as geological structure collapse, is an unsustainable way of energy utilization
