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 irradiation is 747.ZW/ ㎡, and on average encircling temperature is 4.25 ℃, and mean wind speed is 3.2m/s; Without the average irradiation during glass cover-plate working condition measurement, be 776.IW/ ㎡, on average encircling temperature is 9,08 ℃, and mean wind speed is 2.9m/s.
The primary condition of twice test is all the condensed water temperature of 15 ℃, at 10:15
5min starts official testing operation.After condensed water temperature surpasses 55 ℃, test stops.The meteorologic parameter of twice test is similar, and testing equipment and arrange is in full accordly convenient to two kinds of performance comparison under operating mode, and 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 is 220V through inverter inversion, 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 shows, the average condensation power that has cover plate operating mode is 1578.0W, without the average condensation power of cover plate operating mode, is 1271.8W, and condensation power has increased by 24% relatively.The increase of condensation power also can reflect indirectly by the length of heat time.The condensed water of equal in quality is heated to the process of 55 ℃ from 15 ℃, there is cover plate operating mode 146min consuming time, without cover plate operating mode 201min consuming time, there is the heat time of cover plate operating mode obviously to shorten.In the process raising in water temperature, water temperature slope of a curve reduces gradually, and the trend that water temperature raises slows down gradually.Explanation is along with the rising of water temperature, and the condensation power of heat pump reduces gradually, and firing rate slows down.The another one principal element that affects heat pump cycle performance is compressor wasted work.
There is glass cover-plate not only can increase condensation power, also reduced compressor horsepower simultaneously.During 15 ℃ of water temperatures, have, without the compressor horsepower of cover plate, be respectively 169.1w and 264.8w, 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 ℃, the compressor horsepower of two kinds of operating modes is respectively 666.8W and 728.5W.In whole test process, there is the compression horsepower under cover plate operating mode to be all starkly lower than without cover plate operating mode.Have, without the average compressor horsepower under cover plate operating mode, be respectively 433.4W and 532.0w, have cover plate can make compressor horsepower reduce by 23%, directly reduced the system consumption of electric energy to external world.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.Have cover plate operating mode to improve the condensation power of heat pump cycle, reduced the compressor wasted work of heat pump, the COP that therefore has a cover plate operating mode is apparently higher than without cover plate operating mode.As shown in Figure 7, the average COP that has glass cover-plate operating mode is 6.85, without the average COP of glass cover-plate operating mode, is 4.41, and the coefficient of performance has improved 42%.Therefore, glass cover-plate can obviously improve the Thermal Performance in Winter of PV-WT/SAHP system heat pump cycle.Only, for heat pump cycle, adding a cover in the winter time glass cover-plate is more suitably to select.
Above-mentioned experiment shows: 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 all the time in efficient running status.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 the conversion of opto-electronic conversion, photo-thermal, wind electric heating conversion, four kinds of functions of working medium evaporation simultaneously, 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 with current forms by opto-electronic conversion, after inversion conversion, flows to public electric wire net.Adopting wind energy transformation is that electric energy carries out electric power storage storage and low-voltage dc power supply drives the heating of carbon nano-fiber (semiconductor) material, realizes wind, electricity, heat conversion.Adopt Controlled by micro computer, according to the output of intensity of illumination regulate electrical current amount, regulate the calorific intensity of nano carbon fiber heating layer, thereby the heat energy of the wind energy of realization, luminous energy transforms complementary control.
In scene heater (PV-WT) frame, Intensity Analysis controller is housed, difference due to area and weather, the light that is projeced into heat collector is often very unstable, by the monitoring to projection light of Intensity Analysis device, reconcile wind-power electricity generation and store the electric current that power supply is exported, make heat collector temperature constant, thereby realize primary heat source wind photothermal complementary.
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 in sum, make COP≤6 all the time in efficient running status.Photovoltaic generation PV system can provide source pump electric power, for its running.Opto-electronic conversion, photo-thermal conversion, wind electric heating conversion, heat pump cycle are organically combined, form a kind of solar photoelectric/photothermal utilization system-photovoltaic one solar heat pump with heat pump cycle (Photovoltaic Solar Assisted Heat Pump Wind power, PV-WT/SAHP).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 the evaporative cooling process of opto-electronic conversion, photo-thermal, electric heating conversion and 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 are in parallel, during both general differences, open.Water-cooled condenser obtains after heat, can pass through recirculated water, and to room heating or domestic hot-water supply, air-cooled condenser can directly heat to room while starting indirectly.By the switching of magnetic valve and cross valve, the several functions such as system can also complete air-cooled refrigeration, air-cooledly heats, air-cooled water heating.
