<p>This invention is related to design of adsorption modules that overcome the problems of low thermal conductivity of adsorbents, without increasing the thermal mass of the system. Further the adsorption module when integrated into system configurations involving condensers, evaporators and other components, to implement different cycles, deliver characteristics of lower cycle times, high coefficient of performance (COP), high specific cooling power (SCP) with easy operability. The adsorption modules make it possible to develop compact adsorption systems by overcoming the problems of low thermal conductivity of adsorbents without increasing the thermal mass of the adsorption modules, thereby increasing heat transfer rates and reducing cycle time while maintaining high efficacy of the cycles and processes in which they are used. The adsorption module of this invention leads to lower cycle times as low as 5 minutes and makes it possible to achieve high system Coefficient of Performance (COP) up to 0.9 due to reduced thermal mass while offering high specific cooling power in the range of 50 to 750 W/kg of AC when integrated into a system. It is easy to manufacture and operation and reduced the costs. Further this invention discloses a refrigeration cum heating system wherein the heat pipe in thermal contact with the adsorption modules increase the heat transfer rates without increasing the thermal mass leading to increase of COP and single or multistage pressure equalisation increases the internal regeneration of heat thereby increasing the COP, reducing the cycle time resulting in increased specific cooling power (SCP), reducing the required quantity of adsorbent/refrigerant making the module compact and cost effective.</p> |
