Abstract
There is described an apparatus for storing heat. The apparatus comprises a thermal mass for storing heat, the thermal mass having a first surface and a second surface. Fins are provided on the first surface and the second surface for accelerating heat transfer to and from the thermal mass. A displacement mechanism is secured to the thermal mass for translating the first surface to a first environment, e.g., a duct, while removing the second surface and its fins from a second environment, e.g., outside, and for translating the second surface to the second environment while removing the first surface and its fins from the first environment.
Claims10
An apparatus for storing heat, the apparatus operating in a first environment and second environment, the apparatus comprising:
- a thermal mass for storing heat, the thermal mass having a first surface and a second surface;
- fins provided on the first surface and the second surface for accelerating heat transfer to and from the thermal mass, providing additional contact surface to the thermal mass for the heat transfer;
- and
- a displacement mechanism secured to the thermal mass, the displacement mechanism comprising an actuator which is electrically actuated or hydraulically actuated, wherein the actuator is controllable for:
- translating the first surface to the first environment, said translating the first surface comprising removing the second surface and the fins of the second surface from the second environment, and
- translating the second surface to the second environment, said translating the second surface comprising removing the first surface and the fins of the first surface from the first environment.
A method for transferring heat in a duct comprising:
- providing, in the duct, a thermal mass having a heat capacity greater than 2 kJ/kg·K to absorb heat from an air stream of the duct, or release heat to the air stream of the duct, wherein the thermal mass has fins on a first surface and a second surface, wherein transferring the heat comprises exposing fins of only the first surface to the air stream, the fins of the first surface extending on a direction parallel to a direction of the air stream in the duct to form a channel for the air stream;
- displacing the thermal mass out of the duct by actuating, electrically or hydraulically, a displacement mechanism which is secured to the thermal mass, the actuating being controllable to perform a translation of the thermal mass to which the displacement mechanism is secured to expose the thermal mass to outdoors, comprising exposing fins of only the second surface to the outdoors, to absorb heat from the outdoors, or release heat thereto, the displacing the thermal mass out of the duct comprising displacing the second surface with the fins;
- and
- providing a seal around the thermal mass to seal the duct from the outdoors around the thermal mass.
