Description

A kind of solar energy source is stored up supply system the whole year
Technical field
The utility model relates to a kind of solar energy source and stores up supply system the whole year.
Background technology
Along with expanding economy, expending of the energy is more and more, and energy scarcity causes showing great attention to of various countries, is energy-conservationly also day by day paid attention to by people.Create the strategic development planning of economizing type, Innovation-oriented Society according to China, research and development and management that governments at all levels have strengthened resources conservation and utilization of new energy resources drop into; All kinds of enterprises also fall over each other to have strengthened the raising efficiency of energy utilization, the ranks of development and use new forms of energy.Yet the depletion rate of China's non-renewable resources strengthens year by year in recent years, and the environmental problem that the finiteness of resource and development and use cause becomes increasingly conspicuous to the restriction of the sustainable development of socio-economy.Therefore developing regenerative resource becomes trend of the times, and solar energy, this clean environment firendly, inexhaustible regenerative resource is paid attention to by country day by day.
Current continuous progress along with China's science and technology, like a raging fire to exploitation and the trans-utilization of solar energy, such as being used for generating, heating etc., manifest gradually the advantage of solar energy in the various aspects of producing and live.
Especially present, the power consumption of China heating districts heat supply heating accounts for more than 65% of total energy consumption of building, and mainly take the fossil fuel of coal and so on as main, not only utilization rate is low, and seriously polluted for the energy.A large amount of uses of fossil fuel have not only aggravated the Depletion Rate of china natural resources, have also brought serious environmental problem simultaneously.Therefore with the energy source use of this clean environment firendly of solar energy in heating, China's energy strategy is had great importance.The in recent years design of solar energy heating system is implemented, and has brought obvious effect aspect energy-conserving and environment-protective.The main distinction of solar energy heating system and conventional energy resource heating system, be that it is as the energy with solar thermal collector, substitute or partly substitute with the boiler as the energy such as coal, oil, natural gas, electric power, solar thermal collector obtains solar radiant energy and the heat that transforms, delivers to the indoor heating of carrying out by cooling system; In superfluous heat is stored in the heat storage water tank; The heat of collecting when solar thermal collector is replenished by the heat that stores during less than heat load; If during the shortage of heat that stores, provided by auxiliary thermal source for subsequent use.
Solar energy heating system is compared with the conventional energy resource heating system, solar energy heating system is simple in structure, reliable, heat flow density is lower, the temperature that is working medium is also lower, safe and reliable, have the characteristics such as bearing capacity is strong, endotherm area is large, be that building integration optimal selection heating one of is selected.Its range of application is: the zones that the sunlight resource is good and need heat such as enterprise, public institution, factory, universities and colleges, hotel, hospital, community, swimming pool (comprising collective unit and the families such as office).
But the solar energy heat distribution system of current popularization owing to adopting the heat storage water tank heat accumulation, so the heat of its storage is limited more, and the cycle is also shorter, tends to occur the phenomenon of heat supply deficiency, seasonal energy storage can't occur; Because the heat storage water tank floor space is large, cost is high; Although current solar energy heat distribution system also is provided with auxiliary heat supplying, heat sink, such as heat pump etc., the heat of its release is not collected utilization, therefore cause waste to a certain degree, cause whole energy utilization rate lower; Expose pipeline more, easily cause bursting by freezing at the north of china in winter severe cold weather, affect whole heating system operation, and holistic cost is higher.
In sum, need to improve solar energy heat distribution system, reduce its cost, improve its heating efficiency, improve energy utilization rate.
The utility model content
The purpose of this utility model is to propose a kind of solar energy source and stores up supply system the whole year, has solved solar energy function system heating efficiency low, and cost is high, can't realize seasonal energy storage, the problem that energy utilization rate is low.
For reaching this purpose, the utility model by the following technical solutions:
A kind of solar energy source is stored up supply system the whole year, comprise the connected heating refrigeration system of solar thermal collection system, described solar thermal collection system comprises solar thermal collector and heat reservoir, described heat reservoir is the buried U-shaped pipe that is installed in the underground, and described solar thermal collector is connected with heat reservoir in the building underground; Described heating refrigeration system is connected with heat reservoir with solar thermal collector, and described heating refrigeration system comprises heating and refrigeration fan coil system and flooring radiation heating system; Described solar thermal collection system and heating refrigeration system all are connected with running water.
Preferably, also comprise domestic hot-water and auxiliary heating earth-source hot-pump system, described domestic hot-water and auxiliary heating earth-source hot-pump system comprise domestic hot-water's heat exchange box, heat pump, and described domestic hot-water's heat exchange box is connected respectively to heating refrigeration system and running water, and is connected to heat reservoir by heat pump.
As further preferred version, described heat reservoir also comprises a heat-insulation layer, and described heat-insulation layer is positioned at buried U-shaped pipe top.
As preferred version further, the buried U-shaped pipe of described heat reservoir is located at below ground 20-50 rice.
The beneficial effects of the utility model are: exempt from water tank, by utilizing the underground store heat, can remove the employed huge prefabricated thermal insulation heat storage water tank of conventional solar energy system from; Heat accumulation is large, and the earth soil is thermal store maximum on the earth, utilizes its in principle store heat unrestrictedly, and along with the growth of service time, the heat of storage also can increase gradually; Frost-cracking-preventing, the utility model adopt buried U-shaped pipe heat accumulation, expose pipeline less, and heating circulation time in the winter time, can prevent the pipeline bursting by freezing by the circulation anti-freezing mode; Preventing water leakage: the pipeline circulation is closed substantially in the system, and the heat transferring medium in the pipeline is fewer, and unexpected damaged even pipeline occurs, the medium amount of seepage is also very limited, so do not have the heavy losses that cause because metalling run out in a large number; Cost is low, the utility model can be stored into the unnecessary solar thermal energy that three seasons of spring and summer autumn obtain in the surface soil, for use in winter, so only need a small amount of solar thermal collector area just can satisfy the demands, underground pipe is again to adopt the mode of punching to bury underground, so comprehensive cost is lower; Life-span is long, and the basic life-span of the technical program each several part content is all long, and consumable accessory is less, and control is simple, so have long service life.
