Abstract:
A method of operating a cooling system that has at least one evaporator containing a refrigerant and at least one adsorbent chamber containing adsorbent configured to provide adsorption of vaporized refrigerant from the at least one evaporator in a cooling mode and provide desorption of the refrigerant to the at least one evaporator in a recharging mode, the method including; controlling the adsorption and desorption of the refrigerant of the at least one adsorbent chamber between the cooling modes and recharging modes during a cooling cycle; ceasing desorption of the refrigerant from the at least one adsorbent chamber; allowing adsorption of the vaporized refrigerant from the at least one evaporator; and maintaining the at least one adsorbent chamber in an adsorbed state at the end of the cooling cycle in a storage mode.

Abstract:
A sorption module for a sorption temperature-control device may include a housing enclosing a working chamber. A sorption zone and a phase change zone may be arranged in the working chamber where a working medium is displaceable reversibly between the sorption zone and the phase change zone. A sorption structure may be arranged in the sorption zone, and a phase change structure may be arranged in the phase change zone. An outer wall of the housing may include a double-walled section that may provide a cavity between an outer wall part and an inner wall part of the double-walled section, and the phase change zone may be arranged on an inner side of the inner wall part.
Abstract:
Disclosed herein a technique for producing a gas mixture for controlling an oxygen concentration in the interior of a container while reducing the overall weight of the apparatus. For this purpose, a gas mixture supply device is provided for a container refrigeration apparatus. The gas mixture supply device is provided with adsorption columns. If one of the first and second adsorption columns is supplied with air, the adsorption columns are pressurized, and nitrogen in the air is adsorbed onto an adsorbent. If air is sucked from the other of the first and second adsorption columns, the adsorption columns are depressurized, and nitrogen adsorbed onto the adsorbent is desorbed. A gas mixture including the nitrogen desorbed from the adsorbent is supplied to the interior of a container.
Abstract:
An apparatus and method for measuring concentration of a liquid-state refrigerant of a nonazeotrope refrigerant mixture. A container is disposed in such a way that a liquid-state refrigerant mixture of the nonazeotrope refrigerant mixture in a saturated state is temporarily stored with set quality. By measuring temperature and pressure of the liquid-state refrigerant mixture, concentration of the liquid-state refrigerant can be calculated from a database regarding a relationship between a saturation vapor pressure, temperature, quality, and concentration of the previously-stored nonazeotrope refrigerant mixture in the saturated state. Thus, a configuration for measuring the concentration of the liquid-state refrigerant-absorbent mixture includes a container, a temperature sensor and a pressure sensor and thus is very simple and the cost for the configuration can be reduced. In addition, the container can be easily mounted on existing equipment without disturbance of a flow.
Abstract:
Provided in some embodiments is a system that includes a gas compressor including an engine, a compressor driven by the engine, and a vapor absorption cycle (VAC) system driven by waste heat from the compressor, wherein the VAC system is configured to cool at least one medium. In other embodiments is provided a method that includes generating waste heat while compressing a gas, driving a vapor absorption cycle (VAC) system with the waste heat, and cooling at least one medium via the VAC system.
Abstract:
An energy administration device serves for operating an absorption refrigerating device with different energy sources and includes an energy control unit (7) for controlling and selecting an energy source. It includes at least one gas operation unit (8 to 12) for operating said absorption refrigerating device with gas with a gas burner connected to a gas supply line, which can be controlled by a surveillance system. Said surveillance system is an ignition surveillance system and includes an ionisation sensor and/or UV sensor for surveying said gas flame of said gas burner (11).
Abstract:
The burner of a gas refrigerator reduces the temperature by burning gas received from a gas control valve which is opened by the membrane capsule of a thermostat, or closed by a spring. The membrane capsule is connected by a snap spring disc with the gas control valve so that the valve is not slowly opened and closed by the membrane capsule and spring, but rapidly shifted by the snap spring disc between the open and closed positions.
Abstract:
A manual control for a refrigerator which can be operated by either gas or electricity. The control unit can be either two-way or three-way. In the latter, means are provided for switching to any of the following modes: gas; 110 volt A.C.; and 12 volt D.C. The switching mechanism is selectively operative for the desired mode of refrigerator operation.
Abstract:
A control apparatus designed to control the flow of a gas from an inlet to an outlet is shown. The control apparatus includes a housing provided with switch means operatively connected thereto. A gas filled closed member is connected to a bellows with the bellows being responsive to pressure changes within the gas filled member. A gear is connected to a worm screw which in turn is connected to the housing. The gear is also connected to a valve spindle which in turn is connected to control mechanism and to a selectively openable and closeable valve.
