具体实施方式 detailed description

夜晚当电价降低时,装置开始解吸蓄能。 At night when electricity prices lower 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 deg.] C, the adsorber 2 and the valve 4 is opened between the condenser, the adsorbate (water) start out desorbed from the adsorbent and condensed in a condenser 4, 9 and then stored in the accumulator down. 由于解吸过程是吸热过程,所以电能被存储下来。 Because 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 condenser heat release to the air duct 4 is 12 rooms, as the night the building heating. 当吸附质解吸完成后,电加热板7关闭,蓄热过程结束。 When the adsorbate desorption is completed, electric heating plate 7 is closed, the end of the regenerative process.

在白天,电价升高,此时开始吸附供热过程。 During the day, the price increases, then began the process of adsorption heat. 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。 2 valve between the reservoir 9 and the adsorber is opened from the reservoir into the adsorbate adsorbed 9 2, in the form of a spray nozzle through the spray onto the adsorbent, the adsorbent adsorbate began to heat, emitted heat is 12 incoming indoor air duct, 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 to release a lot of heat, so the adsorption heat storage can achieve a high storage density, when using composite adsorbent Physical Chemistry Research Group of the newly developed thermal storage density can be as high 800-1000kJ / kg.
