具体实施方式 detailed description

夜晚当电价降低时,装置开始解吸蓄能。 When night price reduction, the desorption energy storage device starts. 首先电加热板7通电开始加热复合吸附蓄热介质10也就是吸附剂,当吸附剂被加热到150到200℃时,吸附器2与冷凝器4之间的阀门被打开,吸附质(如水)开始从吸附剂中解吸出来,并在冷凝器4中冷凝,然后在储液器9中存储下来。 First, electric heating plate 7 is energized to start heating the composite thermal storage medium 10 is adsorbed adsorbent when the adsorbent is heated to 150 to 200 ℃, adsorber 2 is open and the valve between the condenser 4, adsorbate (water) start desorbed from the adsorbent and condensed in a condenser 4, and then stored in the liquid reservoir 9 down in the. 由于解吸过程是吸热过程,所以电能被存储下来。 Since desorption is an endothermic process, so that energy is stored. 在这一过程中,冷凝器4所放的热量被风道12送到房间,作为建筑物的夜间供热。 In this process, the amount of heat release condenser 4 is sent to the room air duct 12, as heating of buildings at night. 当吸附质解吸完成后,电加热板7关闭,蓄热过程结束。 After the completion of desorption of adsorbate, electric heating plate 7 is closed, the end of the thermal storage process.

在白天,电价升高,此时开始吸附供热过程。 During the day, price increases, then began to heat the adsorption process. 储液器9和吸附器2之间的阀门打开,吸附质从储水器9中进入吸附器2,通过喷头以喷雾的形式喷到吸附剂上,吸附剂吸附吸附质开始放热,所放出的热量被风道12中的空气传入室内,完成放热供暖过程。 A valve between the reservoir 9 and the adsorber is opened, the adsorbate from the adsorber into the reservoir 92, through the spray nozzle as a spray onto the adsorbent, the adsorbent adsorbs adsorbate exotherm started, the released heat is passed in the indoor air duct 12, to complete the exothermic heating process. 由于这一过程要放出大量热,所以吸附蓄热可以达到很高的蓄热密度,当采用本研究课题组最新开发的物理化学复合吸附剂时,蓄热密度可以高达800-1000kJ/kg. Because the process give off a lot of heat, so the adsorption heat storage can achieve a high storage density, when using the present composite adsorbent Physicochemical Research Group newly developed high thermal storage density can 800-1000kJ / kg.
