Abstract

The invention discloses an electroosmotic regenerative adsorption refrigeration system jointly supplied with PEMFC, comprising a first adsorption bed, a second adsorption bed, a first condenser, a second condenser, a first evaporator, a second evaporator, Water replenishment system, hot water tank, cooling tower, chilled water tank, PEMFC system and gas storage tank. Compared with the prior art, the present invention adopts electroosmotic regeneration technology and joint supply technology of adsorption refrigeration system and PEMFC system, and the adsorption refrigeration system Using the waste heat generated by the PEMFC system to run, can quickly form an electroosmotic flow, increase the regeneration rate of the adsorbent, shorten the desorption cycle, and improve the performance of the adsorption refrigeration system. The by-product hydrogen generated by electrolysis can be absorbed by the fuel cell and stored by the battery. , Oxygen can enter the gas storage tank for storage and utilization, so as to achieve the purpose of energy saving, environmental protection and maximum utilization of energy.

Description

technical field [0001] The invention relates to the technical field of adsorption refrigeration, in particular to an electroosmotic regeneration adsorption refrigeration system co-supplied with PEMFC. Background technique [0002] Proton exchange membrane fuel cell (PEMFC) has become an energy-saving and environment-friendly technology with great potential for commercialization due to its high energy conversion efficiency, non-polluting emissions, wide range of fuel sources, low operating temperature, and rapid start-stop. However, PEMFC will generate a large amount of waste heat during operation. In order to meet the ecological concept of energy saving and environmental protection, waste heat utilization has become a hot research issue at present. [0003] Studies have shown that using fuel cell waste heat in a combined heat and power (CHP) system can increase system efficiency to 85%, higher than when only fuel cells are used for power. The fuel cell waste heat can be use...
