But photoelectricity is built in actual motion, and the photoelectric transformation efficiency of photovoltaic cell can be along with the rising of operating temperature
Decline.If directly photovoltaic cell to be laid on building surface, photovoltaic cell while absorbing solar radiant energy, operating temperature
Rise rapidly, generating efficiency can be caused to be decreased obviously.Simultaneously for large-area photovoltaic curtain wall system, photovoltaic curtain wall and curtain wall two
The closing space formed between side and building can produce greenhouse effect after absorbing solar radiant energy because of curtain wall, closes interior volume
A large amount of hot-airs of alluvial rise along curtain wall under heat buoyancy effect, if being drained by hot-air not in time, will cause photovoltaic curtain
Wall tip temperature is too high, not only can affect indoor thermal environment of building, also can have a strong impact on the generating efficiency of photovoltaic cell.
Solar water heater is the device that solar energy is converted into heat energy, by water from low-temperature heat to high temperature, to meet
People's hot water in life, production uses, mainly based on vacuum pipe solar water heater.Vacuum pipe solar water
Device relies on vacuum heat collection pipe that solar energy is converted into heat energy.Vacuum heat collection pipe utilizes the principle that hot water floating cold water sinks, and makes water
Produce microcirculation and reach required hot water.Along with the continuous expansion in city, the highest stratification of urban architecture, roof area is the most not
Can meet the layout of all user's solar water heaters, solar water heater progressively balcony direction to the south is developed.But, due to very
The shortcomings such as blank pipe exists frangible, Maintenance Difficulty, are not appropriate for being used in the platform of skyscraper Nanyang.
Summary of the invention
For prior art exist the problems referred to above, the present invention propose a kind of photovoltaic curtain wall based on architectural exterior-protecting construction and
Residual heat pump utilizes system, can solve to building increase building enclosure and to keep photovoltaic curtain wall work effect by photovoltaic curtain wall
Rate, make full use of the problem such as heat energy produced in photovoltaic curtain wall photoelectric conversion process.The present invention mainly by photovoltaic curtain wall with
Heat pump, while carrying out photovoltaic generation, is supplied to air source heat pump by the unnecessary heat that photovoltaic curtain wall produces by air,
Improve its work efficiency.
In order to solve above-mentioned technical problem, a kind of based on building enclosure curtain wall the photovoltaic of present invention proposition and residual heat pump
Utilizing system, including the stent wall on the outer layer being arranged on building, the top of described building is provided with air source heat pump, described wall
Having space between body support frame and construction outer layer, the medial surface of described stent wall is equipped with photovoltaic curtain wall, described photovoltaic curtain wall
Lower section be provided with multiple air intlet each leading to space, thus between described photovoltaic curtain wall and described construction outer layer, form one
Air buffer；The upper end of described photovoltaic curtain wall is provided with the pipeline connected with described air buffer, and the other end of described pipeline connects
To described air source heat pump, described pipeline is provided with valve, temp testing controlling system and drain blower fan, described temp testing controlling system and institute
State valve to couple.
Further, in the present invention, described stent wall is positioned at the south of described building, and described photovoltaic curtain wall is vertically put
The south being placed in building is used as the building enclosure of building, and the electric energy that described photovoltaic curtain wall produces is transferred to the electrical equipment of building.
The installation of described drain blower fan is oriented after the hot-air suction pipeline in air buffer and import described air
Source heat pump, described air source heat pump provides hot water supply for building.
Compared with prior art, the invention has the beneficial effects as follows:
(1) utilize the features such as air heat transfer property difference, by the air buffer between photovoltaic curtain wall and building body, can reduce
Building and the heat transfer rate of external environment, reduce building energy charge, the most also have noise-reducing, reduce surface of wall frost and dew
The function formed.
(2) the easy temperature influence of the photoelectric transformation efficiency of photovoltaic battery panel, when it normally works in the external world, if not in time
Deriving heat, backboard constant temperature rises, and greatly reduces photoelectric transformation efficiency.The air between building is utilized to carry heat also
Derive in time, temperature too high during work can be reduced, improve photovoltaic efficiency.And the heat energy that photovoltaic generation process produces is added
With Collection utilization, improve the total energy approach rate that system is overall.
(3) operation principle of air source heat pump is Carnot cycle, and with outdoor air as low-temperature receiver, room air is thermal source.?
In the case of keeping other conditions constant, sink temperature is the highest, and the COP of heat pump is the biggest.Therefore, the air source heat of this technology is used
Pump can obtain compared with the higher sink temperature of ambient temperature, it is thus achieved that higher heat pump heats work efficiency.
