Adsorption cooling system using metal organic frameworks
Abstract
An adsorptive cooling system includes two highly adsorptive structures positioned to receive thermal energy from a thermal energy source, each highly adsorptive structure includes a substrate and a metal-organic framework (MOF) coupled to the respective substrate and adapted for adsorbing and desorbing a refrigerant under predetermined thermodynamic conditions. The adsorptive cooling system includes a cooling unit and a circulation system adapted for circulating the refrigerant from one of the highly adsorptive structures to the cooling unit to provide cooling from the thermal energy source and to return the refrigerant from the cooling unit to the same or other highly adsorptive structure. Each substrate may include a plurality of microchannels, providing ingress and egress paths for a refrigerant, defined by grooves in a surface of the substrate nearest the MOF and/or surfaces of a plurality of microcapillaries of the substrate. The microchannels provide ingress and egress paths for a refrigerant.
