Solar photovoltaic generation system is the photovoltaic effect using solar cell semi-conducting material, can be straight by solar radiation Switch through a kind of new power generating system being changed to electric energy, have independent operating and the two ways that is incorporated into the power networks.The photovoltaic of independent operating is sent out Electric system needs accumulator as energy storage device, is mainly used in the no outlying district of electrical network and population decentralization area, whole system System cost is very high；In the area having public electric wire net, photovoltaic generating system is connected with electrical network and is incorporated into the power networks, and saves accumulator, not only Cost can be greatly lowered, and there is higher generating efficiency and more preferable environmental-protecting performance.A set of basic solar energy is sent out Electric system is to be made up of solar panel, charge controller, inverter and accumulator, and below the function of each several part is done with a letter Single introduction：The effect of solar panel is that solar radiant energy is directly changed into unidirectional current, uses for load or is stored in storage Standby in battery.It is typically based on user's needs, some solar panels are pressed certain way and connects, form solaode side Battle array, then mix suitable support and rosette composition.In different types of photovoltaic generating system, charge controller phase not to the utmost Same, its function is how many and complexity difference is very big, and this need to determine according to the requirement of system and significance level.Charge controller Mainly it is made up of electronic devices and components, instrument, relay, switch etc..In solar generating system, the basic role of charge controller It is to provide optimal charging current and voltage for accumulator, quickly, steadily, efficiently for accumulator charge, and in charging process The service life of middle minimizing loss, as far as possible prolongation accumulator；Protect accumulator, it is to avoid the sending out of overcharge and overdischarge phenomenon simultaneously Raw.If user uses DC load, galvanic current can also be provided for load by charge controller（Former due to weather Cause, the galvanic voltage and current that solar cell array sends is not very stable）.The effect of inverter is exactly by solar-electricity The low-voltage DC of pond square formation and accumulator offer is reverse into 220 volts of alternating currents, and supply AC load uses.Accumulator battery be by Solar cell array sends unidirectional current and is stored up for load use.In photovoltaic generating system, battery is in floating charge electric discharge shape State, summer sunshine amount is big, in addition to supply load electricity consumption, also accumulator is charged.When winter sunshine amount is few, this part is stored Electric energy progressively release.Daytime, solar cell array charged a battery, and square formation also will load to load electricity consumption, evening simultaneously Electricity consumption is all supplied by accumulator.It is therefore desirable to the self discharge of accumulator is little, and charge efficiency is high, also will examine simultaneously Consider price and using whether the factor such as convenient.Conventional accumulator has lead-acid accumulator and silica-gel accumulator it is desirable to higher field Close the cadmium-nickel storage cell also having price comparison expensive.

Water source heat pump technology is the low temperature being formed using the solar energy absorbing in earth surface shallow-layer water source and geothermal energy Lowlevel thermal energy resource, and adopt heat pump principle, lead to too small amount of high position electric energy input, realize Lowlevel thermal energy and shift to high level heat A kind of technology.Earth surface shallow-layer water source（Subsoil water, river, lake, ocean etc.）In absorb the sun enter the earth phase When emittance, and the temperature at water source is typically all sufficiently stable.Water source heat pump central air-conditioning system is by end system, water Source heat pump central air conditioner host computer system and water resource heat pump water system three part composition.When winter is user's heat supply, in water resource heat pump Centre air conditioning system extracts low grade heat energy, by the water-source heat-pump central air conditioner main frame of electrical energy drive from water source（Heat pump）" pump " Deliver to high temperature heat source, delivered to as after refrigerating medium lifting temperature using air or water and in building, meet user's heat demand.Summer During for user's cooling, the indoor waste heat of user is passed through water source central air conditioner main machine by water source heat pump central air-conditioning system（Refrigeration）Turn Move on in source water, due to water source temperature low it is possible to efficiently take away heat, to meet user's refrigeration demand.Generally water Source heat pump consumes the energy of 1kW, and user can obtain heat or the cold of more than 4kW.With traditional boiler（Electricity, fuel）Heat supply System is compared, and water resource heat pump has obvious advantage.Boiler heat supplying can only be by the fuel of 90%～95% electric energy or 55～80% Interior energy is converted into heat, and therefore water resource heat pump saves more than 2/3rds electric energy, ratio fuel boiler section than grill pan stove heat Save more than 1/2nd energy.For summary, mainly there are following characteristics：1）Belong to renewable energy utilization technology.Source pump It is to make use of the energy that earth water body stored as Cooling and Heat Source, carry out heating, the air conditioning system of energy conversion, wherein can profit Water body includes subsoil water, surface water, process cycles cooling water, mine drainage etc..Surface soil and water body are not only one Huge solar thermal collector, have collected 47% solar radiation energy, more than 500 times of utilization energy more annual than the mankind（Ground Under water body be that solar radiation energy is indirectly accepted by soil）, and be a huge dynamic power balance system, ground The soil of table and water body keep energy acceptance and the relative equilibrium dissipating naturally.This makes using being stored in intimate nothing therein The solar energy of limit or ground can be possibly realized.Thus, water resource heat pump using be cleaning regenerative resource a kind of technology.By Relatively stable in the heat source temperature whole year of water resource heat pump, generally 8～30 DEG C, its refrigeration, heating efficiency are up to 3.8～4.4.Cause This, in recent ten years, over especially past 5 years, water source heat pump air conditioning system North America as the U.S., Canada and in, Northern Europe for example auspicious The countries such as scholar, Sweden achieve and develop faster, the water resource heat pump market of China also increasingly active it is contemplated that, this technology This century maximally effective heat supply and cooling air-conditioning technical will be become.2）Energy-efficient.The available water body of water source heat pump units Temperature winter is 8～30 DEG C, and water temperature is higher than ambient air temperature, so the evaporating temperature of heat pump cycle improves, Energy Efficiency Ratio Also improve.Estimate according to U.S. Environmental Protection Agency (EPA) EPA, the good water resource heat pump of design and installation, can save on average user 30～ 40% operating cost.Heat pump why energy-conservation it is important that be exactly a little in the heat that it is provided major part be from Low temperature side gratuitously obtains, if the heating efficiency of heat pump is 4, is equivalent to and has 3 parts of energy gratuitously to obtain from low temperature side, and only consume 1 part of electric energy.For water source heat pump units, heat transfer process is to complete with water bodys such as subsoil water, surface water, recirculated waters , typically at 10～22 DEG C about, substantially free from the influence of the external environment.3）Stable and reliable operation.The temperature of water body 1 year four Aspect, to stable, is good source heat pump heat, the more constant characteristic of water temperature so that source pump run more reliable, stable, Also ensure that high efficiency and the economy of system.Compared with combustion gas and oil-fired boiler system, eliminate oil-stocking equipment and Gas Pipe Laying of road, if coal-burning boiler system then can save boiler room and matched coal yard and slag field, greatly reduces machine The floor space in room, has saved land resource, produces additional economic benefit, improves the utilization rate of building.4）Environmental benefit Significantly.Water resource heat pump uses electric energy, and electric energy is originally as a kind of energy of cleaning.The electric power designing good water source heat pump units disappears Consumption, compared with electricity heating, is equivalent to minimizing more than 70%.Water source heat pump technology adopt cold-producing medium, can be R22 or R134A, R407C and R410A etc. substitutes symplasm, and the operation of water source heat pump units does not have any pollution, does not also have garbage it is not necessary to stack The place of fuel exhaust, and without long-distance sand transport heat.Heat pump in the winter time heat supply when eliminate boiler house system, do not have , thus there is not blast, the hidden danger of burning in combustion process, no combustion apparatus, it is to avoid the discharge of noxious fume and harmful substance. Source pump operation is safe and reliable, stable, is hardly affected by weather and variation of ambient temperature, meets environmental protection concept.5）One Machine is multiplex, applied range.Water source heat pump system can heat, air-conditioning, also can domestic hot-water supply, a tractor serves several purposes, set of system can To replace two covering devices or the system that original boiler adds air-conditioning.Especially for the demand having heat supply and cooling, water source simultaneously Heat pump has clear advantage.Not only save mass energy, and heat supply and cooling can be met with a set of equipment simultaneously Require, decrease the initial cost of equipment.6）Automatic running.Water source heat pump units are due to stable conditions it is possible to design is simple System, part is less, and unit operation is simple and reliable, and maintenance cost is low；The degree that automatically controls is high, and long service life can reach 20 More than year.Typical case's application system of water source heat pump of water source heat pump system is by end（Room air processes end etc.）System System, water source central air conditioner main machine（It is also called water resource heat pump）System and water source water system three part composition.For during user's heat supply, water Source central air conditioner system middle extraction low grade heat energy from water source, by the water source central air conditioner main machine of electrical energy drive（Heat pump）" High temperature heat source delivered to by pump ", to meet user's heat demand.During for user's cooling, water source central air-conditioning is by waste heat indoor for user By water source central air conditioner main machine（Refrigeration）Transfer in water source, to meet user's refrigeration demand.User（Indoor end etc.）System , by user side water pipe system, water circulating pump, water filter, Electrostatic water treatment instrument, various ends airhandling equipment, it is fixed to expand for system Pressure equipment and related valve accessory composition.Water source central air conditioner main machine system by compressor, vaporizer, condenser, expansion valve, respectively Plant the composition such as refrigeration piping accessory and electrical apparatus control system.By water source water fetching device, water pump, water process sets water source water system Standby, water transfer pipe network and valve fittings etc. form.Cooling condition can be realized by valve transfer, even if source water enters condenser, The freeze cycle water of vaporizer connects custom system.

Fuse salt technology is exactly that common solid-solid inorganic salt is heated to its fusing point liquid formed above (if NaNO3 is 308 DEG C fusing, common NaCl salt melts at 801 DEG C), then reach solar energy heat-transferring accumulation of heat using the thermal cycle of fuse salt Purpose.Compared with traditional working medium, fuse salt have using wide temperature range (from tens degrees Celsius to more than 1,000 degrees Celsius), A series of huge advantages of the close Hatton of Chinese such as heat transfer property height, the low, low price of operating pressure, fusion tray of thermal transmission and storage technology is Through having obtained extensive utilization in fields such as chemical industry, military projects, in new high-tech such as solar energy thermal-power-generating, biomass high-temperature hydrogen manufacturing Field also has broad application prospects.The U.S. takes the lead in employing fuse salt as the heat transfer accumulation of heat working medium of solar energy thermal-power-generating, And achieve good effect on SolarTwo solar energy thermal-power-generating experiment power station.In July, 2010, Italian Civil electric power collection Group Sicily built up the world first completely using fuse salt accumulation of heat Archimedes's solar light-heat power-generation station.Accumulation of heat material Material is exactly a kind of new chemical material that can store heat energy.It issues biological phase transformation in specific temperature (as phase transition temperature) Change, and along with absorbing or releasing heat, can be used to control the temperature of surrounding, or in order to store heat energy.It heat or Cold stores, and it is discharged when needed again, thus improve the utilization rate of the energy.The work process of heat-storing material Including two stages：One is the storage stage of heat, power unnecessary for peak period, industrial exhaust heat used heat or solar energy etc. is led to Cross heat-storing material to store；Two is the release stage of heat, discharges heat when using by heat-storing material, is used for adopting Warm, heat supply etc..Heat storage and release step cycle are carried out it is possible to solve heat energy over time and space using heat-storing material Incoordination, reach high efficiency of energy using and energy-conservation purpose.To divide by heat storage type, heat-storing material can be divided into four classes： Sensible heat heat-storing material, phase change heat storage material, heat chemistry heat-storing material and adsorptive heat-storage material.1st, sensible heat heat-storing material.Sensible heat stores Hot material is the storage to carry out heat for the change procedure using material self-temperature, due to direct contact heat transfer can be adopted, Or fluid inherently heat storage medium, thus storage, exothermic process are relatively simple, are early stage to apply more accumulation of heat material Material.The simplest also comparative maturity of sensible heat heat storage technology in all of heat-storing material.Sensible heat heat-storing material major part can be from certainly So boundary directly obtains, cheap and easy to get.Sensible heat heat-storing material is divided into liquid and solid two types, fluent material common as water, Solid material such as rock, cobblestone, soil etc., wherein have several sensible heat heat-storing materials noticeable, such as Li₂O and Al₂O₃、TiO₂ Mixing material Deng high temperature sinter molding.Because sensible heat heat-storing material is that the temperature change relying on heat-storing material to carry out heat storage Deposit, exothermic process is unable to constant temperature, thermal storage density is little, cause the bulky of thermal storage equipment, heat storage efficiency is not high, and with week There is the temperature difference and can cause thermal loss in collarette border, heat is unable to long term storage, is not suitable for long-time, Large Copacity accumulation of heat, limits The development further of sensible heat heat-storing material.2nd, phase change heat storage material.Phase change heat storage material is in phase transformation using material（As solidification/ Fusing, condensation/vaporization, solidification/distillation etc.）Storage and utilization to carry out heat for the heat of transformation that process occurs.With sensible heat accumulation of heat Material is compared, and phase change heat storage material thermal storage density is high, can release amount of heat at a constant temperature by phase transformation.Although gas one liquid and The solid latent heat of phase change value changing of gas one is more solid transformation than liquid one, latent heat that is consolidating when changing is big, but because it is in phase transition process There is the great variety of volume so as to can there is very big difficulty in practical implementation.High, the latent-heat storage according to phase transition temperature Low temperature and two kinds of high temperature can be divided into, low temperature latent-heat storage is mainly used in Waste Heat Recovery, storage of solar energy and heat supply and air-conditioning system System.High-temperature phase change heat accumulation material mainly has high temperature melting salt, mixing salt, metal and alloy etc., is mainly used in Aero-Space Deng.Common latent heat storage material has calcium chloride hexahydrate, Sodium acetate trihydrate, Organic Alcohol etc..It is close that latent-heat storage mode has accumulation of heat Spend higher (typically can reach more than 200kJ/kg), store, the approximate isothermal of exothermic process, the advantages of process is easily controlled, because This phase change heat storage material is the main flow of current heat-storing material research and application.3rd, heat chemistry heat-storing material.Heat chemistry heat-storing material Many using metal hydride and amic sting inverse chemical reaction and carry out accumulation of heat, having catalyst, temperature high and away from equilibrium state Intermittent fever response speed is fast.The external experimentation carrying out solar energy storage heat generating using this reaction, but need emphasis to consider storage Container and the tightness of system, and generate gas to the problems such as the corrosion of material.Heat chemistry heat-storing material has thermal storage density High and cleaning, pollution-free the advantages of, but course of reaction is complicated, technical difficulty height, and device security had high demands, disposably Investment is big, still has relatively large distance with practical engineering application.4th, adsorptive heat-storage material.Absorption refers to fluid phase (containing a kind of or many The gas of kind of component or liquid) when contacting with the solid particle with porous, solid particle (i.e. adsorbent) is to adsorbate Sorption or hold and stay process.Because of the heterogencity on adsorbent solids surface, produce the conversion effet of energy along with adsorption process, claim For heat of adsorption.In adsorption/desorption circulation, grade and the use time of heat can be changed by heat storage, release process, Realize the purposes such as refrigeration, heat supply and accumulation of heat.Adsorptive heat-storage is a kind of new heat storage technology, and research is started late, and is using suction Attached working medium is come to storage and the conversion carrying out heat in adsorption/desorption cyclic process with the heat effect occurring.Adsorptive heat-storage material The thermal storage density of material may be up to 800～1000kJ/kg, has the advantages that thermal storage density height, heat-accumulating process empty calory lose.Due to Adsorptive heat-storage material non-toxic is pollution-free, is another study hotspot in addition to phase change heat storage material, but due to adsorptive heat-storage material It is usually porous material, heat and mass transfer performance is poor, and adsorptive heat-storage is complex, be the problem that primary study solves.

Two kinds of environment-protecting clean energy technologys can merge, but existing fusion method is usually by photovoltaic There is provided the simple fusion of electric energy for water source heat pump system, energy utilization efficiency is not high.

Content of the invention

The invention solves the problems that water source heat pump technology and two kinds of environment-protecting clean energy technologys of solar photovoltaic technology are more preferable Merge problem, design a kind of solar energy heat distribution system, this " hot " is " hot " physically, heat supply include freeze with Heating etc., adopts the ripe water source heat pump system of existing Technical comparing and solar photovoltaic generation system, by accumulation of heat simultaneously , as the intermediary of two systems, thus energy utilization efficiency is higher, it is less to be lost, two kinds of technological incorporation degree are higher for water tank, its Technical scheme is as follows：

Including hot water storage tank, as the intermediary of two systems, the water in hot water storage tank is by solar photovoltaic generation system light Volt assembly generated electricity without the direct powered by direct current of inversion heat, at this moment solar photovoltaic generation system shouldn't inverter, light Volt assembly electricity is unidirectional current, does not also have because unidirectional current is converted to the energy that alternating current causes if being not required to change that Loss.Also electrical heating can be supplied through the converting direct-current power into alternating-current power that photovoltaic module is sent out in inversion, solar energy under regular situation Photovoltaic generating system all comprises inverter and by inverter converting direct-current power into alternating-current power, but inevitable lossy in conversion. Meanwhile, hot water storage tank is user's heat supply as the thermal source of water source heat pump system（Including refrigeration and heating etc.）, water source heat pump system Obtain energy, the electricity of such solar photovoltaic generation system from hot water storage tank, eventually become water source heat pump system Energy is originated.Water source heat pump system also can be converted to electric energy rather than lively the energy of hot water storage tank, at this moment can to power, Due to more than once conversion（Water source heat pump system becomes heat energy into electric energy）, necessarily have more energy loss；But, Ke Yi Daytime is converted to thermal energy storage in hot water storage tank the electricity of solar photovoltaic generation system, and evening is again hot water storage tank The energy of middle storage is converted to electric energy for using, use of realizing staggering the time.Hot water storage tank more than 1 simultaneously water source heat pump system permissible The selected hot water storage tank as thermal source of switching, an energy obtains almost then uses another water tank；Solar energy power generating system System can also switch selected supply electrically heated hot water storage tank, a hot water storage tank heats almost to go and heats another accumulation of heat The water of water tank；The ability of so accumulation of energy energy supply of whole system is adjustable, can be used as needed, such system Can run more sane.Hot water storage tank can be installed on interior, underground or roof, and interior is applicable to normal domestic use occasion Heat supply is used, and underground is suitable for building, cell central heating is used（It is also with soil heat preservation even with geothermal energy simultaneously）, roof It is also applied for normal domestic use occasion heat supply to use.Certainly, above-mentioned solar photovoltaic generation system can be also directly water source heat pump system Power supply, at this moment generated electricity can be similar with the water in above heat storage water tank for photovoltaic module, and one is can be directly straight without inversion Stream electricity is powered for described water source heat pump system, and two is also can to power for described water source heat pump system through being reverse into alternating current, excellent scarce Point is the same.Also commercial power complementary system can included, supplemented by described commercial power complementary system when solar energy power generating is not enough and supply Electrical heating, and it is delivered to commercial power complementary system when solar energy power generating has more；Existing solar water heater etc. has electricity Concurrent heating system, function is somewhat similar, but also grid-connected directly electricity can be transported to electrical network when solar energy power generating has many here, There are a lot of support policies in much countries including China for solar grid-connected generating at present, can therefrom make a profit.Due to Water in hot water storage tank also directly can utilize these hot water through solar photovoltaic generation system for becoming hot water after electrical heating, It is further added by a hot water supply system, directly for user for the hot water in described hot water storage tank, certainly in hot water storage tank more than 1 When individual, hot water supply system should also the same with solar photovoltaic generation system with water source heat pump system above can switch selected As the hot water storage tank of thermal water source, a hot water is finished the hot water with another water tank.

It is not the sensible heat heat-storing material of water, phase transformation that the hot water storage tank of above-mentioned solar energy heat distribution system can be replaced heat storage medium The regenerative apparatus of heat-storing material, heat chemistry heat-storing material or adsorptive heat-storage material, simultaneously described water source heat pump system replace with phase The heat pump answered or electricity generation system.Water can not only be used for sensible heat heat-storing material also can phase change heat storage material, sometimes also with some special Oil is fuse salt as sensible heat heat-storing material, common phase change heat storage material, and fuse salt is divided into low-temperature heat accumulating fuse salt, high temperature again Accumulation of heat fuse salt.In the case of having multiple regenerative apparatuses, can the heat storage medium that has of different regenerative apparatuses be also watery fusion Salt have for high-temperature heat accumulation fuse salt, respectively take the chief.

The maximum feature of hot water storage tank is that its hot water can be used with direct-furnish, and heat storage medium is not the sensible heat accumulation of heat material of water Heat-storing material in material, the regenerative apparatus of phase change heat storage material, heat chemistry heat-storing material or adsorptive heat-storage material typically can not be straight For using（Certainly specifically can be used with direct-furnish using scene at some）But the heat storage capacity of some heat-storing materials significantly more than Water is it is possible to combine use the heat storage technology of both above solar energy heat distribution system.If with hot water storage tank as accumulation of heat Based on the solar energy heat distribution system of carrier, then be exactly that to set up heat storage medium thereon be not the sensible heat heat-storing material of water, phase The regenerative apparatus of change heat storage material, heat chemistry heat-storing material or adsorptive heat-storage material and corresponding heat pump or electricity generation system, accumulation of heat Heat storage medium in device is generated electricity without the direct powered by direct current of inversion by described solar photovoltaic generation system photovoltaic module Heat or through being reverse into AC-powered heating, and the energy that corresponding heat pump or electricity generation system are realized storing regenerative apparatus passes It is delivered to original hot water storage tank, this hot water storage tank still thermal source as water source heat pump system, that is, water source heat pump system is again from accumulation of heat Obtaining energy in water tank is user's heat and power supply；Same heat storage medium is not the sensible heat heat-storing material of water, phase change heat storage material, heat The regenerative apparatus quantity of chemical heat-accumulating material or adsorptive heat-storage material can exceed 1 and solar photovoltaic generation system can basis Need switching selected for electrically heated regenerative apparatus.It is not water due to there is hot water storage tank and heat storage medium in this programme simultaneously Sensible heat heat-storing material, the regenerative apparatus of phase change heat storage material, heat chemistry heat-storing material or adsorptive heat-storage material, and regenerative apparatus Energy will pass to hot water storage tank it is possible to hot water storage tank by fully wrapped around for regenerative apparatus or portion envelops, so The natural heat dissipation of regenerative apparatus can be absorbed by hot water storage tank, more reduces the loss of energy.

The solar energy heat distribution system made according to technique scheme, storage heating（Power supply）Ability is controlled, can be very strong Can also meet as needed, energy loss is little on the whole simultaneously, solar energy utilization ratio is high（It is also with geothermal energy）, institute simultaneously Using technology maturation, related product also comparative maturity on the market, price is no longer high, the construction cost of this sample system Will not be too high.
