| Research Abstract |
In this project, adsorption heat pump (AHP) technology was investigated by the researchers in the field of chemistry, chemical engineering and architecture. The aim of this project is (1) increase in the output of AHP system, (2) the promotion of heat and mass transfer diffusion in the AHP module, and (3) the optimization and controlling technology of the effective system for use of cold heat energy. As for the system design, the alcohol/activated carbon absorption heat pump (AHP) with a disk-module -type absorber was also proposed for producing of high quality and high power cold heat energy. The heat and mass transfer characteristics in adsorption and regeneration processes of the AHP operation were experimentally investigated. It was found that the adsorption/regeneration cycle period was about 10 times shorter than that of the packed-bed-type adsorber of SAC. The equilibrium adsorption capacity per weight was reduced by SAC modulation, but the cold heat output per unit time of the proposed AHP system was enlarged. The present system works well with regeneration temperatures of around 350 K and readily generates cold heat at around 270 K. It is concluded that AHP fabricated with the proposed disk-module adsorber units can be used as a compact refrigeration unit for generating cold heat energy below 273 K by using a low temperature waste heat energy source. Secondly, the adsorption properties of porous silica materials, i.e., zeolites, FSM-16, MCM-41 and amorphous silica, were characterized by various physico-chemical techniques. It was found that they have radical sites which is active for some chemical reactions on their surfaces. Finally, the local heat energy system, including offices, residences and stores, with AHP drove by cold heart from factories as heat sources was simulated. The effectiveness of the use of AHP for the local energy system was clarified.
