The present invention concerns a device and a process for the storage and restitution of heat which comprises at least two concentric heat storage volumes (TES1, TES2, TES3). The walls (2) delimiting these storage volumes are configured in a manner such that the thickness of the wall delimiting the central storage volume is greater than the thickness of the wall delimiting the peripheral storage volume.

A thermal heat storage system is provided, including a storage tank, a heat injection system and a heat recovery system. The storage tank holds a material for thermal storage. The heat injection system is coupled to an intake on the storage tank. The heat recovery system is coupled to an output on the storage tank and also uses vapor under depressurized conditions for heat transfer.

A compact cooling system based on thermoelastic effect is provided. In one embodiment, the system comprises a pair of rollers serving as a heat sink, stress applicator and belt drive, a cold reservoir and a solid refrigerant belt coupled to the cold reservoir and to the heat sinks to pump heat from the cold reservoir to the heat sink. The refrigerant belt comprises solid thermoelastic materials capable of thermoelastic effect. The refrigerant material is mechanically compressed when entering the gap of the roller and subsequently released after passing through. When compressed the refrigerant material transforms to martensite phase and releases heat to the roller and neighboring materials. After released by the rollers, the refrigerant material transforms back to austenite and absorbs heat from the ambient atmosphere.

The invention is a container (200) for a system for storing and restoring heat, comprising a vessel including means for injecting and withdrawing a gas to be cooled or reheated. The vessel is limited by a first jacket formed from concrete (203) surrounded by a thermally insulating layer (206), which is surrounded by a steel shell (204). The vessel comprises at least two modules formed from concrete (210) located one above the other and centered to form a first jacket from concrete (203). Each module formed from concrete comprises a volume limited by a side wall formed from concrete (211) and a perforated base formed from concrete (205). The volume contains a fixed bed of particles of a material for the storage and restitution of heat (207).

An adsorption system can be used as part of a climate control system in a vehicle or in any other space requiring heating or cooling.

A thermal transfer blanket includes a flexible container comprising a thermally insulating material. A thermal energy storage media is disposed within the flexible container.

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.

A dual air flow exchanger, allowing a heat transfer and humidity transfer between two air flows, and including a plurality of first and second air circulation networks separated by membranes permeable to water vapor and impermeable to air and to liquid water, each of the first and second networks including cells each defined by a wall including openings for passage of air, the cell wall including two opposing edges at which same is open in a direction of stacking. For at least one of the first networks, at least one of the two opposing edges of each cell wall defines a hollow open in a direction of the second directly consecutive air circulation network, the hollows receiving a part of the second network.
