Description
Technical field
The invention patent relates to field of solar energy utilization, in particular to a kind of solar energy of combination phase-change microcapsule
Photo-thermal system.
Background technique
In recent years, the problem of environmental pollution generated with the shortage of resources of traditional energy with it increasingly aggravates, so that traditional
The change of energy resource structure is imperative, thus renewable energy (such as solar energy, biomass energy) develop into it is more popular
Research emphasis.Wherein, the renewable energy that solar energy can be used permanently as one kind, clean and environmental protection inexhaustible with its make
With it is safe the advantages that, have powerful competitiveness.The energy utilization patterns of solar energy are divided into two classes: solar thermal utilization and photoelectricity benefit
With.The wherein most important building block of photovoltaic power generation --- photovoltaic module Shortcomings, i.e., in the case of a high temperature, photovoltaic power generation member
The generating efficiency of device can accordingly decline, and be unable to give full play the function of its power generation.Therefore, photovoltaic conversion effect how is sufficiently solved
The problem of rate reduces under high temperature environment becomes one of the theme of current photovoltaic power generation technology concern.
However, existing integral type photovoltaic/photo-thermal heat collector (evaporator and photovoltaic module direct-coupling) mode exists centainly
The drawbacks of: first is that being difficult to solve the matching problem between photovoltaic area and photo-thermal area, still due to current photoelectric conversion efficiency
Relatively low, about the 20% of sun investment radiation is converted into electric energy, and remaining 80% is nearly all converted to thermal energy, this
The heat that the generated energy of the PV/T evaporator under same area is numerically much smaller than is allowed for, so as to cause in practical production
In product, photovoltaic capacity and heat pump capacity are difficult to match；Second is that system flexibility is poor, since photovoltaic module is direct with evaporator
It is coupled, therefore photovoltaic system and heat pump system can be restrained mutually, so that the actual motion of heat pump is influenced by solar irradiation
More serious, stability is poor；And the efficient operation in order to guarantee photovoltaic module, heat pump must be constantly in operation on daytime
State, otherwise battery cannot be cooled down effectively, and at this time if user does not have the demand of heat, energy waste will be generated；Third is that
The occupied area and refrigerant line crushing of PV/T evaporator are big, cause the circuit of evaporator refrigerant too long, and crushing is larger, from
And the performance of heat pump is reduced, in addition the fabricating yard of system also tends to be limited.
Summary of the invention
The technical problem to be solved is that in view of the defects existing in the prior art, provide a kind of combination phase transformation for the invention patent
The photovoltaic and photothermal solar system of microcapsules.
In order to solve this technical problem, the invention patent provides a kind of photovoltaic and photothermal solar of combination phase-change microcapsule
System, including photovoltaic module, intermediate hot water storage tank, evaporator, compressor, condenser, flow controller, domestic hot-water's case, feature
Be: the photovoltaic module is combined in series and parallel by photovoltaic panel, and is attached to form closed circuit with intermediate hot water storage tank,
To carry out the cooling of photovoltaic module by the cooling device of photovoltaic back, and transfer heat in intermediate hot water storage tank.
Contain phase-change microcapsule in the intermediate hot water storage tank, the heat shifted is stored and extracted.
The utility model has the advantages that the invention patent innovatively installs circulating cooling system additional between photovoltaic module and evaporator, rule
Problem brought by evaporator with heat pump and photovoltaic module direct-coupling is kept away, is played the two indirect association by circulating cooling system
Come, after the heat storage that cooling will obtain in the phase-change microcapsule in intermediate hot water storage tank, to be provided when solar energy deficiency
The supply of hot water amount.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the invention patent；
Appended drawing reference: hot water storage tank, 3- phase-change microcapsule, 4- evaporator, 5- compressor, 6- among 1- photovoltaic module, 2-
Condenser, 7- flow controller, 8- domestic hot-water's case.
Specific embodiment
For the purposes, technical schemes and advantages of the invention patent are more clearly understood, below in conjunction with specific embodiment, and
Referring to attached drawing, the invention patent is further described.

Figure, including photovoltaic module 1, intermediate hot water storage tank 2, evaporator 4, compressor 5, condenser 6, flow controller 7, domestic hot-water's case 8,
Be characterized in that: the photovoltaic module 1 is combined in series and parallel by photovoltaic panel, and is attached to be formed with intermediate hot water storage tank 2 and be closed
Circuit is closed, to carry out the cooling of photovoltaic module 1 by the cooling device of photovoltaic back, and transfers heat to intermediate accumulation of heat water
In case 2.
Contain phase-change microcapsule 3 in the intermediate hot water storage tank 2, the heat shifted is stored and extracted, with rule
Keep away the drawbacks such as solar energy discontinuity, discontinuity.
The practical approach of the invention patent:
When carrying out photoelectric conversion power generation by photovoltaic module, photovoltaic panel bulk temperature rises, and bring effect is just
It is photoelectric conversion efficiency reduction, therefore, the present apparatus is extracted heat by the cooling device at the photovoltaic module back side, and storage is extremely
