The Study On The Air-condition System Of Solar Energy And Geothermal-source Heat Pump

Solar energy is a sort of never-failing clean energy source, and how to moreeffectively utilize it has increasingly become a hot spot scientists tap with efforts. Thecharacteristic of heat pump consist in that it can transfer heat from low temperature tohigh temperature, and improve the rates of low temperature heat sources. There will bea great future if we integrate solar energy utilization techniques into heat pumptechniques. On the base of integrating the two techniques, the paper analyzed the arttrait of the air-condition system of solar energy and geothermal-source heat pump,theconcept of the solar energy and geothermal-source heat pump type air-conditionsystem is proposed;the working principle of this system has been studied in thispaper;and how to control system.This paper introduced the transfer model and the computational method of theplate-type solar energy collection heat and the hot tubular vacuum tube collection hotheat in detail, have studied the hot tubular vacuum tube collection heat moduleengineering design method and the movement pattern with emphasis, has overcome thefrost of the big area solar energy collection is used in the north cold area. To theair-source, the water-source and the geothermal-source of three kinds of heat pumpspatterns have carried on the introduction, according to the actual need of the study,mainly has conducted the thorough research to the geothermal-source heat pump, haddetermined buried the heat interchanger concrete form and has established the heattransfer model. Unifies the concrete project, has carried on the detailed theoreticalcalculation and the project implementation plan design to the air-condition system ofsolar energy and geothermal-source heat pump, and confirms the system in technologyfeasibility using the system measured data and the theoretical calculation contrast.The union system construction and the movement actual situation, this articlecarried on the efficient analysis to this system, the analysis result had proven thissystem design extremely reasonable, was extremely feasible in the economy. Themovement effect demonstrated this system energy conservation effect extremelyobvious, when this system is used in Winter the heating coefficient of performancemay reach 4.5 equally, in Summer the refrigerating coefficient of performance to beeven may reach 3.8, the operating cost may with burn coal quite, but has not pollutednearly. The researched results indicated that the air-condition system of solar energyand geothermal-source heat pump is completely feasible in the technology and theeconomy, has the research and the promoted value very much.
