A solar-powered two-bed adsorption chiller which can operate after sunset when the solar radiation intensity becomes zero. Rechargeable solar-powered batteries (SPBs) are connected to a flat-plate solar collector (FPSC). The photoelectric charges are directed from FPSC to a solar charge controller (SCC) which acts as a charge amplifier thus magnifying the total charge before it is finally collected inside the SPB for future use. The SPB is in turn connected to a resistance heating wire (RHW) which is immersed inside the HWST.

A solar collection system includes an absorption refrigeration system to generate water from atmospheric moisture, and to do so without the use of an electrically operated compressor. At least a portion of the solar energy captured by the solar collection system is used to operate the absorption refrigeration cycle. The absorption refrigeration cycle provides cooling that causes water in the atmosphere to condense into a liquid that can be collected and used for various applications. As one example, the collected liquid can be used for the cleaning of the solar collection system of contaminants like dust or bird drippings. In other applications, the water can be used outside the solar collection system including, but not limited to, irrigation, drinking, and other industrial purposes.

A refrigeration and/or heat transfer device includes a heating section and cooling section, a release member, and a one-way check valve affixed together in a continuous loop so working fluid may flow in one direction therein. The heating section absorbs heat and transfers such heat to the working fluid, thereby heating, expanding and increasing pressure upon the working fluid therein. The pressurized working fluid is released in a regulated manner from the heating section to the cooling section, thereby carrying the heat away. The released working fluid cools and transfers its heat to the surroundings within the cooling section. As released working fluid enters the cooling section, such fluid displaces already cooled working fluid, pushing such fluid through the one-way check valve back into the heating section to absorb heat. The working fluid may undergo a phase change or remain in a single phase throughout to enhance heat transfer.

A system may include a beverage compartment with a beverage positioned therein, a wetted material disposed about the beverage, at least one sorption cartridge, and a vacuum pump. The sorption cartridge may be in communication with the beverage compartment, and the vacuum pump may be in communication with the sorption cartridge to create a vacuum in the sorption cartridge and the beverage compartment, causing water to evaporate from the wetted material and be captured by the sorption cartridge, thereby lowering the temperature of the wetted material and in turn cooling the beverage. In some instances, the sorption cartridge may be detached from the vacuum pump and the beverage compartment to discharge the captured water therein by way of solar energy. In other instances, the sorption cartridge may be in communication with a heater assembly to blow heated air through the sorption cartridge to discharge the captured water therein.

An adsorptive cooling system includes: a first highly adsorptive structure positioned to receive thermal energy from a thermal energy source, the first highly adsorptive structure including: a first substrate; and a first carbon aerogel adhered to the first substrate, a second highly adsorptive structure positioned to receive thermal energy from the thermal energy source, the second highly adsorptive structure including: a second substrate; and a second carbon aerogel adhered to the second substrate, a cooling unit; and a circulation system adapted for circulating the refrigerant from at least one of the first highly adsorptive structure and the second highly adsorptive structure to the cooling unit to provide cooling from the thermal energy source and to return the refrigerant from the cooling unit to at least one of the first highly adsorptive structure and the second highly adsorptive structure.

Disclosed is a system for conditioning air, the system comprising: a heat exchanger comprising a plurality of heat transfer tubes extending between an accumulation header and an outlet header, an internal volume, and an external surface, wherein an air mover is disposed in fluid communication with an air mover in fluid communication with an air inlet and an air outlet, wherein the air mover is configured to urge a flow of air to be conditioned across the external surface of the heat exchanger, a reactor comprising an adsorbent material, a reactor inlet in fluid communication with the outlet header, and a reactor outlet, a vacuum pump comprising a vacuum pump inlet in fluid communication with the reactor outlet and a vacuum pump outlet in fluid communication with a system exhaust.

A solar collection system is provided in which an absorption refrigeration system is included to generate water from atmospheric moisture, and to do so without the use of an electrically operated compressor. At least a portion of the solar energy captured by the solar collection system is used to operate the absorption refrigeration cycle. The absorption refrigeration cycle provides cooling that causes water in the atmosphere to condense into a liquid that can be collected and used for various applications.

In other applications, the water can be used outside the solar collection system including, but not limited to, irrigation, drinking, and other industrial purposes.

There is provided a system and a method for transferring energy, the method comprising the steps of: a)feeding a material comprising an absorbed fluid into a tube, b) heating the tube so that the fluid is desorbed in gas phase from the material, so that a fluid flow is created by the desorbed fluid in the tube, causing a flow of the material present as particles, and c) performing one of i) separating the material from the fluid so that a charged material is obtained, and ii)cooling the material and fluid so that the fluid is absorbed by the material whereby heat is released. An advantage is that no active transport means such as pumps are needed to transport the material during charging.

The integrated desalination and air conditioning system can provide desalinated (fresh) water, cold air or both in a single efficient system. The system incorporates a humidification-dehumidification (HdH) desalination system with a water-lithium bromide (H.sub.2O—LiBr) vapor absorption cycle (AbC) system. The AbC system includes an AbC generator that provides a heating source for an AbC condenser that heats the air input of the HdH; two AbC absorbers that provide heating sources for the feed seawater; a first AbC evaporator that provides a cooling source for the humidified air produced in the HdH; and a second AbC evaporator that provides a cooling source for use outside the system. The heat input for the AbC generator can be provided by low-grade heat sources, such as waste heat or solar thermal energy. The system is capable of producing fresh water and/or cold air at different capacities, depending on water demands and cooling load requirements.
