  • Patent number: 4527398
    Abstract: A process using a cascade desiccant air-conditioning/air drying apparatus having cold thermal energy storage means is used to produce a major increase in the system's thermal coefficient of performance. The latent heat of vaporization from the water separation occurring in desiccant regeneration is recovered in the heating process for desiccant regeneration in the next stage. This energy recovery results in a major improvement in thermal coefficient of performance in air-conditioning or air drying processes. Values greater than 1.0 are expected to be common and values greater than 2.0 are possible. Presently most thermal driven air-conditioning systems have a thermal coefficient of performance less than 1.0 with an average value less than 0.7.

  • Patent number: 4507925
    Abstract: A process has been invented to inject and withdraw water from an aquifer for purposes of energy storage under some abnormal conditions. This transfer system is for thermal energy storage applications where the transfer water pressure is higher than the normal aquifer pressure at the point of withdrawal or injection. Applications include systems where water temperatures are in excess of the normal boiling point and the water must be pressurized, to prevent boiling and/or and where an aquifer has a water head well below ground level creating excess pressure from the column of water from the surface to the acquifer. Water is injected through a process which reduces the pressure at the aquifer to the pressure required for injecting the correct water flow rate. In recovering the thermal energy, or withdrawal, the system provides the proper pressurization at aquifer level to the required pressure.

  • Patent number: 4459814
    Abstract: A thermal energy compression system wherein the refrigerant in a heat pump or air-conditioner is compressed by thermal energy in the compression system rather than by work in a standard compressor. The compression uses an intermittent compression process with a solid absorbent. The vapor is absorbed by an absorbent at relatively low temperature and ejected as the absorbent temperature is raised and a set of one way valves limits flow to one direction so as to improve heat transfer requirements, to allow for molecular sieve-refrigerant matching, minimizing non-producing mass, solving thermal fatigue and shock problems, and use of the system in parallel with a standard compressor, automobile air-conditioning applications and truck refrigeration applications.
