Abstract
The invention described herein enables a variety of heating, cooling, energy transformation, and energy storage options with a small number or components. Described are Pressure Swing Adsorption and Pressure Swing Desorption cycles, processes, and apparatuses including multiple sorption beds and active energy input by a pump and energy storage as pressure differentials. A preferred embodiment includes two activated carbon sorption beds, water vapor as the adsorbate, control valves, and a compressor or vacuum pump. In operation these components provide a range of heating, cooling, and energy storage options. Operational cycles are described.
Claims20
1) A thermal energy transfer system comprising;
- an adsorbate pump,
- an adsorbate,
- an adsorbent within a first sorption bed,
- wherein said pump performs a process selected from the group consisting of;
- said pump raises pressure within said first sorption bed whereby exothermic adsorption occurs and when said adsorption occurs, a system performance curve results wherein, said curve is derived from at least one equilibrium adsorption or desorption isotherm curve with an inflexion point slope greater than 0.1 mol/kg/kPa, said exothermic energy being transferred to heat an application,
- and said pump lowers pressure within said first sorption bed whereby endothermic desorption occurs and when said desorption occurs a system performance curve results wherein, said curve is derived from at least one equilibrium adsorption or desorption isotherm curve with an inflexion point slope greater than 0.1 mol/kg/kPa, said endothermic energy being transferred from an application to cool it.
11) A thermal energy transfer system comprising;
- A valve,
- an adsorbate,
- an adsorbent within a first sorption bed,
- wherein said valve performs a process selected from the group consisting of;
- said valve opens causing a pressure increase within said first sorption bed whereby exothermic adsorption occurs and when said adsorption occurs, a system performance curve results wherein, said curve is derived from at least one equilibrium adsorption or desorption isotherm curve with an inflexion point slope greater than 0.1 mol/kg/kPa, said exothermic energy being transferred to heat an application,
- and said valve opens causing a pressure decrease within said first sorption bed whereby endothermic desorption occurs and when said desorption occurs a system performance curve results wherein, said curve is derived from at least one equilibrium adsorption or desorption isotherm curve with an inflexion point slope greater than 0.1 mol/kg/kPa, said endothermic energy being transferred from an application to cool it.
