Investigation of a single consolidated adsorber cooling system

The description of an adsorption cooling machine is presented with a single consolidated adsorber and activated carbon-methanol pair. A new consolidated adsorbent block made of activated carbon mixed with a binder with good heat transfer properties has been developed and implemented in the adsorber. The design is focused on the adsorber consisting of copper finned tubes and carbon blocks. This paper describes experimental results of such a prototype operating with an intermittent cycle and a cycle time of 35 minutes. The thermal conditions used to test the cycle are: the heat source, 110degreesC-125degreesC; the heat sink, 22degreesC; the evaporator temperature corresponding to the chilled ethylene glycol temperature of VC to -5degreesC. The operating cycle of the machine is described, along with typical experimental observations of pressure and temperature in the adsorber. At those evaporating pressure, the mass transfer resistance controls the adsorption process. Based on improvement of the mass transfer, Making of a two-bed adsorptive prototype refrigeration machine is under construction. The present work therefore presents a study of a consolidated adsorber which is intended to receive high SCP.
