A new family of crystalline microporous metallophosphates designated AlPO-91 has been synthesized. These metallophosphates are represented by the empirical formula
C.sub.c.sup.+A.sub.a.sup.+M.sub.m.sup.2+EP.sub.xSi.sub.yO.sub.z
where M is a divalent framework metal such as magnesium or zinc, C is a cyclic organoammonium cation, A is an acyclic organoammonium cation, and E is a trivalent framework element such as aluminum or gallium. The AlPO-91 compositions are characterized by a new unique ABC-6 net structure, and have catalytic properties suitable for carrying out various hydrocarbon conversion processes, as well as characteristics suitable for the efficient adsorption of water vapor in a variety of applications, such as adsorption heat pumps.

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. The adsorbent system can include an enclosure, a plurality of layers arranged in a stack inside the enclosure, and a vapor channel inside the enclosure.

A cooling system for a vehicle cab where the vehicle has an internal combustion engine is provided. The system comprises a cooling chamber having an ambient air intake, and first and second pairs of sorption vessels. Each pair of sorption vessels comprises a first sorption vessel containing a sorption solution which is located in the cooling chamber and is in fluid communication with a second sorption vessel located outside the cooling chamber. The system further comprises first and second cooling circuits, each circuit containing a coolant and being in heat exchange contact with a respective one of the second sorption vessels. A first control valve selectively directs coolant from the first or the second cooling circuit towards the cab. An exhaust passage conveys exhaust gases away from the engine, and the exhaust passage has at least one exhaust aperture in communication with the cooling chamber. A moveable flap is located within the cooling chamber so as to divide the cooling chamber into a first chamber portion containing one of the first sorption vessels, and a second chamber portion containing the other of the first sorption vessels. The moveable flap is moveable between: a first position in which exhaust gas flows from the at least one exhaust aperture through the first chamber portion whilst ambient air flows from the air intake through the second chamber portion, and a second position in which exhaust gas flows from the at least one exhaust aperture through the second chamber portion whilst ambient air flows from the air intake through the first chamber portion.

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.

An exhaust gas flow control system disclosed relates to the field of mechanical engineering. The system reduces exhaust gas back pressure exerted on an internal combustion engine and prevents excessive heat loss in a radiator. The system comprises a flow regulator connected to an outlet of a silencer and configured to selectively direct the flow of exhaust gases to a metal hydride heat pump and/or a tailpipe. The flow of exhaust gases is directed towards the metal hydride heat pump in case of increased cooling requirement in the vehicle, and to the tailpipe in case of no cooling requirement or maintenance of the metal hydride heat pump. In case of reduced cooling requirement, partial flow of exhaust gases is directed to the metal hydride heat pump and the remaining to the tailpipe. A diverter is configured within the flow regulator to selectively direct the flow of exhaust gases.

An air-conditioning system is provided for a motor vehicle. That system includes a vacuum enclosure having a refrigerant, a first section and a second section. The system further includes a radiator, a core and a phase change material vessel downstream from the core. A conduit and valve system operate the air-conditioning system in two modes of operation.

A cooling system including a first cooling apparatus thermally exposed to a space to be cooled. The cooling system further includes a second cooling apparatus thermally exposed to the space to be cooled and thermally exposed to the first cooling apparatus. Heat discharged from the second cooling apparatus powers the first cooling apparatus.

A motor vehicle may include an internal combustion engine and an air-conditioning system, which may include a heat exchanger and a compression refrigeration system. The heat exchanger and the compression refrigeration system may be incorporated into a coolant circuit configured to communicate a coolant flow and may have a pump. The compression refrigeration machine may be driven at least one of directly and indirectly via the internal combustion engine. An adsorption system may be incorporated into the coolant circuit and may be connected to the internal combustion engine in a heat-transferring manner. The adsorption system may be configured to receive a waste heat load from the internal combustion engine for operation. A valve device may be incorporated into the coolant circuit and be switchable between at least two position for distributing the coolant flow between the adsorption system and the compression refrigeration system.
