Abstract
A method to use high temperature thermal storage for integration into building heating/cooling systems and to meet building's peak power demand. The method can be used to store the thermal energy at any desirable rate and then discharge this stored energy to meet the demand for short or long time intervals. Input energy stored with this method is thermal energy, however, output can be thermal or electric based upon the requirement.
Claims14
A method for managing thermal storage capability of a building, the method comprising:
- blowing air, after it has been determined that the building is entering a time of peak energy load, the air being blown at a first temperature through a thermal storage bed comprising a number of packed beds;
- the thermal storage bed having thermal energy stored therein;
- permitting air at the first temperature to absorb heat from the thermal storage bed, thereby heating the air to a second temperature;
- and
- circulating the air at the second temperature to one of the building or one or more thermo-electric devices;
- wherein the thermal energy has been stored in the thermal storage bed by:
- (a) initially injecting fluid, the fluid being used in a heat and mass transfer operation, into a first packed bed from a first number of packed beds;
- said first packed bed being an input packed bed;
- a sensor being disposed between each consecutive one of the number of packed beds from the number of packed beds;
- exit of the fluid being enabled a second number of packed beds away from and along a flow path including the input packed bed;
- a packed bed the second number of packed beds away from the input packed bed being an output packed bed;
- (b) sensing, utilizing the sensor between the input packed bed and a consecutive packed bed, a quantity representative of the heat and mass transfer operation;
- (c) transferring, if output of the sensor disposed between the input packed bed and a next packed bed in the flow path exceeds a predetermined sensor output, injection of fluid from the input packed bed to the next packed bed in the flow path, referred to as a successor packed bed, the input packed bed becoming isolated, and transferring the exit of fluid from the output packed bed to a packed bed succeeding the output packed bed and next to the output packed bed, referred to as a follower packed bed;
- wherein, when output of the sensor disposed between the input packed bed and a next packed bed in the flow path exceeds a predetermined sensor output, the input packed bed is taken out of the flow path and fluid inlet injects fluid directly into the successor packed bed;
- wherein the follower packed bed was not previously in the flow path;
- the successor packed bed becoming the input packed bed and the follower packed bed becoming the output packed bed;
- wherein, since the fluid is injected into the input packed bed and exits from the output packed bed, flow is in a series connection from the input packed bed to the output packed bed;
- (d) Repeating steps (b) and (c) until the output packed bed is a last packed bed from the first number of packed beds.
