The invention relates to a phase-change material reservoir 9 for a heat exchanger of an air-conditioning installation of a vehicle, the reservoir 9 being arranged between two reservoir plates 10a, 10b and having filling means 14, characterized in that the filling means 14 include at least one tube 15 delimiting a filling channel 19 arranged outside the reservoir 9against a first plate 10a of the reservoir 9.

A system is for infusing liquid with a gas to form a gas-infused beverage. The system has a tank with first and second cavities. A refrigeration circuit refrigerates the tank and the contents of the first and second cavities. The liquid is supplied to the first cavity and cooled therein by the refrigeration circuit and then supplied to the second cavity and infused with gas therein to thereby form the gas-infused beverage. The gas-infused beverage is then supplied to a beverage outlet for dispensing to a user.

A compressed air energy storage power generation device equipped with: a compressor mechanically connected to a motor; a first pressure storage tank storing compressed air from the compressor; an expansion device driven by compressed air from the tank; a generator mechanically connected to the expansion device; a first heat exchanger that exchanges heat between a heat medium and the compressed air supplied from the compressor to the tank; a second heat exchanger that exchanges heat between the heat medium and the compressed air supplied from the tank to the expansion device; a pressure sensor that detects the state of charge (SOC) of the tank; SOC adjustment units that adjusts the SOC; and a control device. The control device controls the SOC adjustment units such that the detected SOC is within an optimal SOC range while satisfying the requested power. Thus, in this compressed air energy storage power generation device the SOC is controlled so as to be within an optimal SOC range, so the operating efficiency can be improved.

The heater block of the present disclosure can transfer heat from a heat transfer fluid to a received fuel fluid, air passing in proximity to the heater block or combinations thereof. These heat transfers reduce, substantially prevent or prevent the freezing of water within the received fuel fluid and/or the air as it enters an intake member of a gas burning unit.

A method for operating a heat exchange system is provided. The heat exchange system includes at least one heat exchange chamber with heat exchange chamber boundaries which surround at least one heat exchange chamber interior of the heat exchange chamber, wherein the heat exchange chamber boundaries comprise at least one first opening for guiding in an inflow of at least one heat transfer fluid into the heat exchange chamber interior and at least one second opening for guiding out an outflow of the heat transfer fluid out of the heat exchange chamber interior, at least one heat storage material is arranged in the heat exchange chamber interior such that a heat exchange flow of the heat transfer fluid through the heat exchange chamber interior causes a heat exchange between the heat storage material and the heat transfer fluid.

A thermal energy store comprising a chamber having a gas inlet and a gas outlet and a plurality of successive, downstream, gas permeable thermal storage layers disposed between them, each layer comprising gas permeable thermal storage media, the store being configured for gas flow from the gas inlet to gas outlet through the layers for transfer of thermal energy to or from the thermal storage media, wherein at least one of the layers is a valved layer provided with at least one valve operable selectively to allow or prevent at least some gas flow through that layer via the valve so as to bypass the thermal storage media. A control system may selectively alter the flow path of the gas flowing from inlet to outlet in response to the progress of a thermal front, so as to bypass thermal storage layers upstream of the thermal front, where transfer is complete, or downstream thereof, where transfer is minimal.

The heater block of the present disclosure can transfer heat from a heat transfer fluid to a received fuel fluid, air passing in proximity to the heater block or combinations thereof. These heat transfers reduce, substantially prevent or prevent the freezing of water within the received fuel fluid and/or the air as it enters an intake member of a gas burning unit.

A thermal energy storage and power generation system includes a thermal energy storage device including a container, a heating element in the container, a pair of fins in the container and arranged on opposite sides of the heating element, a thermal storage material in the container, and a tube in the container and extending around the thermal storage material. The system also includes a generator in communication with the thermal energy storage device for converting thermal energy into electrical energy as well as subsystems for regulating and controlling the system.

A kit including a plurality of separate and distinct identically sized phase change material-containing panels shaped as a frustum of a right pyramid, a method of assembling a thermal insulating enclosure from such panels and the resultant assembled thermal insulting enclosure.

Provided is an hybrid solar heat absorption cooling system comprising: an absorption refrigerator; a solar heat steam generator configured to generate steam using solar heat; a daytime steam supplying unit configured to supply steam generated by the solar heat steam generator during the day as a heat source for the absorption refrigerator; a daytime hot water storage tank configured to store hot water discharged from the absorption refrigerator during the day; a nighttime hot water supplying unit configured to supply hot water stored in the daytime hot water storage tank during the night as a heat source for the absorption refrigerator; a nighttime hot water storage tank configured to store hot water discharged from the absorption refrigerator during the night; and a daytime hot water supplying unit configured to supply hot water stored in the nighttime hot water storage tank during the day to the solar heat steam generator.
