A composite material including a covalent organic framework (COF) single crystal having a major axis length of larger than 120 μm or a COF polycrystal including a plurality of the single crystals, and at least one heat-storage compound. The heat-storage compound is a compound that generates heat or absorbs heat by adsorption to or desorption from the COF single crystal. Also, a heat dissipation/storage member containing the composite material as a heat storage/dissipation material a COF single crystal having a major axis length of larger than 120 μm, and a method for producing a COF single crystal by crystallizing COF raw material compounds via a solution containing an ionic liquid or an organic salt and an equilibrium adjusting agent to grow a COF single crystal.

A heat store comprises heat-storage bodies for storing thermal energy, a housing, in which the heat-storage bodies are accommodated; and at least one line for a heat-transfer fluid, in order to feed thermal energy to the heat-storage bodies and/or carry it away from the heat-storage bodies. Each of the heat-storage bodies comprises a metal rail of an elongated form, the cross-section of which has a web between widened ends.

Provided herein are systems and methods for the processing of exhaust gases of industrial processes in order to reduce or eliminate emission of pollutants (including carbon dioxide) and store energy in the form of cryogenic liquids. Advantageously, the provided systems and methods utilize advanced heat exchanger systems to reduce or eliminate the net power required for operation. The heat exchangers are used both to reduce effluent gases to liquid temperatures as well as reheat previously cooled and separated gases, which can generate electricity via a turbo generator. The described systems and method may also produce cryogenic liquid products (Argon, Krypton, liquid Oxygen, liquid Nitrogen, etc.).

Secondary loop air conditioning and heat pump systems include a reservoir with a capsule holding a phase change material.

A thermal capacitor includes a shell and a PCM. The shell includes a first major surface that is configured to contact a container including media to be frozen. The shell defines a cavity in which the PCM is disposed. The PCM has a transition temperature in a range of −80 degrees Celsius to −50 degrees Celsius and is configured to rapidly freeze media from room temperature to −60 degrees Celsius with the container including the media in contact with the shell in an enclosed space.

The present invention provides a bottle type cooling pack including a case, which: has a storage space formed therein to store a refrigerant including a phase change material (PCM), the phase of which varies according to temperature; has a front surface and a rear surface, the widths of which are wider than that of a side surface thereof; and has a rectangular hexahedral shape formed through the front surface and rear surface and curved in the forward and backward directions.

The invention provides a heat-storage medium conveying system for a solar-thermal power plant. The system includes a high-level tank subsystem including a high-level tank used to store the heat-storage medium. The system further includes a heat-storage medium transport subsystem. The high-level tank subsystem is connected with the heat-storage medium transport subsystem. The heat-storage medium transport subsystem includes a low-level tank. A mounting height of the low-level tank is lower than that of the high-level tank. A volume of the low-level tank is smaller than a volume of the high-level tank. The heat-storage medium can enter the low-level tank from the high-level tank partially or completely by its own gravity. The low-level tank is provided with a conveying pump, and the heat-storage medium is pumped out of the low-level tank through the conveying pump. The invention solves the problems such as construction cost, operation and maintenance cost brought about by using the vertical long-shaft submerged molten salt pump, while avoiding the potential safety hazards in the design of large and small tanks or high-level and low-level tanks.
