  • Patent number: 10753236
    Abstract: Systems and methods are provided for data center cooling by vaporizing fuel using data center waste heat. The systems include, for instance, an electricity-generating assembly, a liquid fuel storage, and a heat transfer system. The electricity-generating assembly generates electricity from a fuel vapor for supply to the data center. The liquid fuel storage is coupled to supply the fuel vapor, and the heat transfer system is associated with the data center and the liquid fuel storage. In an operational mode, the heat transfer system transfers the data center waste heat to the liquid fuel storage to facilitate vaporization of liquid fuel to produce the fuel vapor for supply to the electricity-generating assembly. The system may be implemented with the liquid fuel storage and heat transfer system being the primary fuel vapor source, or a back-up fuel vapor source.

  • Publication number: 20130291574
    Abstract: Cooling systems using adsorption are described. The cooling systems use an adsorption cycle without continuous heat input and over a long duration. The cooling system can function by vaporizing a liquid at a reduced pressure. The cooling systems have applications in developing countries, in both arid and non-arid regions, allowing, for example, for the operation of refrigerators and small air conditioners without electrical input. The cooling systems can be used for cold storage. The cooling systems can present a greener alternative to conventional cooling methods in developed countries.

  • Publication number: 20130269375
    Abstract: Vapour absorption refrigeration is carried out by condensing, in a condensing stage (98), a refrigerant in vapour form to obtain condensed refrigerant, being passed into an expansion/evaporation stage (16) in which it is subjected to heat transfer with a higher temperature medium (29) such that at least some of the refrigerant evaporates. Vapourised refrigerant passes from the evaporation stage into an absorption stage (30) in which some of it is absorbed, at a first pressure, into an absorbent, thereby to obtain partially refrigerant-enriched absorbent. This absorbent is contacted, in a compression absorption stage (58) at a second pressure greater than the first pressure, with vapourised refrigerant, rendering refrigerant-enriched absorbent which is passed from the compression absorption stage into a refrigerant regeneration stage (62), in which refrigerant in vapour form is recovered, rendering refrigerant-depleted absorbent.

  • Publication number: 20130263616
    Abstract: In a devolatilization/solution concentration process, the feed stream is pre-heated and further heated to a temperature which is higher than the normal boiling point, evaporated into a circulating gaseous medium to obtain a concentrated stream, and the vapor in the circulating gaseous medium is condensed to provide the pre-heating and produce a condensed stream. Increasing the temperature span between the heated stream and the cooled, concentrated stream provides more energy for evaporation into the circulating gaseous medium and improves the performance. The process is thus better adapted for fresh-water production, salt-solution concentration, volatile-matter extraction, air conditioning, refrigeration, low-temperature heat energy upgrading, and electricity generation. Examples of the relevant applications are also provided.
