Example Embodiment

[0021] At night when the price of electricity drops, the device starts to desorb and store energy. First, the electric heating plate 7 is energized to start heating the composite adsorption heat storage medium 10, which is the adsorbent. When the adsorbent is heated to 150 to 200°C, the valve between the adsorber 2 and the condenser 4 is opened, and the adsorbent (such as water) Begin to desorb from the adsorbent, condense in the condenser 4, and then store it in the accumulator 9. Since the desorption process is an endothermic process, the electrical energy is stored. In this process, the heat emitted by the condenser 4 is sent to the room by the air duct 12 as the night heating of the building. When the adsorbate desorption is completed, the electric heating plate 7 is turned off, and the heat storage process ends.

[0022] During the day, the price of electricity rises, and the process of adsorption heating begins at this time. The valve between the reservoir 9 and the adsorber...

Abstract

The invention is a kind of sorption heat reservation electric heating method and the device, it carries on sorption heat reservation by using sorption heat in sorption process with sorption agent and sorption media, using the difference in price of electricity of peak and valley, uses the electrically heats and makes the sorption agent to desorbing the sorption media, and reserves the electricity energy as heat energy mode, the sorption media is frozen in the condensator and discharged into the room, the frozen sorption media is stored in the water storage box; opens the valve in daylight, the sorption media is sprayed onto the sorption bed with liquid type, and discharges the accumulate energy at night into the room, realizes heat reservation at night, and heat supplying in daylight. The device is made up of box, condensator, wind channel, sorption device, liquid storage device, pump, sorption channel, the sorption device connects with the condensator, and the liquid storage device.

Description

technical field [0001] The invention relates to a heat storage energy storage method and a device thereof, in particular to an adsorption type heat storage electric heating method and a device thereof which use the heat of adsorption in the adsorption process of an adsorbent and an adsorbate to carry out adsorption heat storage. Background technique [0002] As human beings pay more and more attention to energy conservation, development of new energy sources and environmental protection, thermal energy storage technology has received more and more attention from all over the world and has been more and more widely used. In the 1960s, the United States began research on heat absorbers / regenerators. Garrett Company successively designed 3kW and 10.5kW space thermal devices, and conducted a large number of component performance experiments; Promoted the development of high-temperature phase-change heat storage technology; the United States proposed to ...
