experiment relevant parameter:
Test position: north latitude 43o49 ' 52.61 " east longitude 125o17 ' 50.48 ".On June 25th, 2013 intensity of solar radiation figure (see figure 9);
Average lamp is 747.ZW/ ㎡, and average ring temperature is 4.25 DEG C, and mean wind speed is 3.2m/s; Be 776.IW/ ㎡ without the average lamp during glass cover-plate working condition measurement, average ring temperature is 9,08 DEG C, and mean wind speed is 2.9m/s.
The primary condition of twice test is all the condensed water temperature of 15 DEG C, at 10:15
5min starts official testing and runs.After condensed water temperature is more than 55 DEG C, test stops.The meteorologic parameter of twice test is similar, testing equipment and arrange completely the same, and be convenient to the performance comparison under two kinds of operating modes, meteorological data is shown in figure.In process of the test, valve 1, valve 2, valve 5, valve 6 are closed, and valve 3, valve 4, valve 7, valve 8 are opened, and compressor is (40Hz) operation frequently surely.PV battery obtains the DC current output that voltage is 48V, after the alternating current that inverter inversion is 220V, by extraneous load consumption.Storing water in water tank 80kg, water cooling heat exchanger water effluent speed 0.217 ㎏/s.
The height of heat pump cycle hot property is the most directly reflected in condensation power, and statistics display, have the average condensation power of cover plate operating mode to be 1578.0W, the average condensation power without cover plate operating mode is 1271.8W, and condensation power adds 24% relatively.The increase of condensation power also can be reflected by the length of heat time indirectly.Be heated to the process of 55 DEG C from 15 DEG C at the condensed water of equal in quality, have cover plate operating mode 146min consuming time, without cover plate operating mode 201min consuming time, have the heat time of cover plate operating mode obviously to shorten.In the process that water temperature raises, the slope of water temperature curve reduces gradually, and the trend that water temperature raises slows down gradually.Rising along with water temperature is described, the condensation power of heat pump reduces gradually, and firing rate slows down.The another one principal element affecting heat pump cycle performance is compressor wasted work.
There is glass cover-plate not only can increase condensation power, also reduce compressor horsepower simultaneously.During water temperature 15 DEG C, have, be respectively 169.1w and 264.8w without the compressor horsepower of cover plate, along with the rising of water temperature, the compressor horsepower of two kinds of operating modes all obviously strengthens, and when water temperature is elevated to 55 DEG C, the compressor horsepower of two kinds of operating modes is respectively 666.8W and 728.5W.In whole test process, the compression horsepower under cover plate operating mode is had all to be starkly lower than without cover plate operating mode.Have, be respectively 433.4W and 532.0w without the average compressor power under cover plate operating mode, have cover plate that compressor horsepower can be made to reduce by 23%, directly decrease the consumption of system external circle electric energy.The overall performance of heat pump cycle generally represents with coefficient of performance, and coefficient of performance is the ratio of heat income and system wasted work.There is cover plate operating mode to improve the condensation power of heat pump cycle, reduce the compressor wasted work of heat pump, therefore have the COP of cover plate operating mode apparently higher than without cover plate operating mode.As shown in Figure 7, have the average COP of glass cover-plate operating mode to be 6.85, the average COP without glass cover-plate operating mode is 4.41, and the coefficient of performance improves 42%.Therefore, glass cover-plate can significantly improve the Thermal Performance in Winter of PV-WT/SAHP system heat pump circulation.Only for heat pump cycle, cover glass cover plate more suitably selects in the winter time.
Above-mentioned experiment shows: after the modularized design of PV-WT scene heater, can constitute jointly as view energy source heat pump (PV-WT/SAHP) system, make COP≤6 be in efficient operation all the time with common water source heat pump units.Photovoltaic generation PV system can provide source pump electric power, for its running.
By adopting special vacuum lamination process and insulating heat-conduction material that photovoltaic cell and thermo-compression evaporation parts are combined as a whole, form the PV evaporimeter with good thermal conductivity, electrical insulation capability.PV evaporimeter can carry out simultaneously opto-electronic conversion, photothermal deformation, wind electric heating conversion, working medium evaporates four kinds of functions, is flat sheet mould structure, both can with building or integrated with wall body, also can place separately.After solar irradiation is received by PV evaporimeter, 0.6-0.7
wave band irradiation is exported as an electrical current by opto-electronic conversion, flows to public electric wire net after inversion conversion.Adopt wind energy transformation to be that electric energy carries out electric power storage storage and low-voltage dc power supply drives the heating of carbon nano-fiber (semiconductor) material, realize wind, electricity, hot-cast socket.Adopt Controlled by micro computer, according to the calorific intensity of intensity of illumination regulate electrical current amount Drazin inverse nano carbon fiber heating layer, thus realize the thermal energy complementation control of wind energy, luminous energy.
In scene heater (PV-WT) frame, Intensity Analysis controller is housed, due to difference that is regional and weather, the light being projeced into heat collector is often very unstable, by the monitoring to projection light of Intensity Analysis device, reconcile the electric current that wind-power electricity generation stores power supply output, make heat collector temperature constant, thus realize primary heat source wind photothermal complementary.
In sum after the modularized design of PV-WT scene heater, can constitute jointly with common water source heat pump units as view energy source heat pump (PV-WT/SAHP) system, make COP≤6 be in efficient operation all the time.Photovoltaic generation PV system can provide source pump electric power, for its running.Opto-electronic conversion, photothermal deformation, wind electric heating conversion, heat pump cycle are organically combined, form a kind of solar photoelectric/photothermal utilization system-photovoltaic one solar heat pump (PhotovoltaicSolarAssistedHeatPumpWindpower, PV-WT/SAHP) with heat pump cycle.In PV-WT/SAHP system, photovoltaic cell and evaporator with heat pump organically combine, and form photovoltaic evaporimeter.Photovoltaic evaporimeter is the critical component of PV-SAHP system, can carry out opto-electronic conversion, photo-thermal, electric heating conversion and the evaporative cooling process of heat pump fluid simultaneously.On the one hand, heat pump directly utilizes solar irradiation as evaporation thermal source, and performance coefficient of heat pump is improved; On the other hand, due to the evaporation of heat pump fluid, photovoltaic cell obtains sub-cooled, and photoelectric transformation efficiency is improved.Air-cooled condenser and water-cooled condenser parallel connection, open during both general differences.After water-cooled condenser obtains heat, can recirculated water be passed through, indirectly to rooms or domestic hot-water supply, can directly to rooms when air-cooled condenser starts.By the switching of magnetic valve and cross valve, the several functions such as system can also complete air-cooled refrigeration, air-cooledly to heat, air-cooled water heating.
