Abstract: An absorption heat pump having a generator, a heat source to heat the generator to drive coolant vapor out of solution, a condenser for cooling the coolant vapor and an expansion valve that expand the coolant fluid as well as an evaporator for at least partial evaporation of the expanded coolant fluid against a medium which is connected to at least one absorber which absorbs the expanded coolant fluid. A hot gas line which branches off from a line for coolant vapor upstream of the condenser and is fluid-connected to the evaporator such that it bypasses the condenser and the expansion valve, a defrosting valve being provided in the hot gas line, by means of which the flow of coolant vapor through the hot gas line can be controlled. The absorption heat pump is operated in a cyclic circulation process.

Abstract: Disclosed are systems and methods of intelligently cooling thermal loads by providing a burst mode cooling system for rapid cooling, and an auxiliary cooling system that controls the temperature of the thermal load and surrounding environment between burst mode cooling cycles.

Abstract: Disclosed are systems and methods of rapidly cooling thermal loads by providing a burst mode cooling system for rapid cooling. The burst mode cooling system may include a complex compound sorber configured to rapidly absorb ammonia.

Abstract: A thermal energy battery for cooling temperature sensitive components comprises a composite of a sorbent with ammonia, water, alcohol, amine or a fluorocarbon refrigerant absorbed thereon and incorporated on a substrate material. The composite is encased in a containment material configured to rupture or otherwise release refrigerant desorbed by the sorbent composition when internal battery pressure reaches a threshold ?P from the outside pressure, and thermal conduction means in thermal contact with the thermal energy battery and one or more temperature sensitive components for directing thermal energy therebetween to heat the composite and cool the temperature sensitive components.

Abstract: The invention regards a self-supporting, substantially cuboid vacuum container which is particularly thin-walled, and the use thereof especially for adsorption devices.

Abstract: This application discloses a control logic for maintaining a proper solution concentration within an absorption chiller. Further, safeguards are added to a system control to ensure robust operation when operated in a co-generation application with a heat source such as a micro-turbine, a reciprocating engine, etc. In such applications, in proper management of the heat flow into the chiller from such sources can result in crystallization of the absorption solution, which would be undesirable. Inventive control logic works to minimize such occurrences.

Abstract: An absorption refrigerating machines-group apparatus that can be installed at reduced cost and prevent the occurrence of abnormal situations due to the unexpected suspension of the operation of a cooling water pump is provided. The absorption refrigerating machines-group apparatus according to the invention comprises a control panel 200 for issuing control signals, an adapter 300 having a control section 310 for relaying control signals and absorption refrigerating machines 100A, 100B, 100C having respective control sections 80, said control sections 310 and 80 being connected by a telecommunications line L51. When a signal for suspending the operation of the shared cooling water pump is relayed, the currently operating absorption refrigerating machines are brought into a temporary state that allows the operation of the cooling water pump P2 to be suspended through an exchange of signals between the control sections 310 and 80.
