Abstract: A method of manufacturing a catalyst material includes the steps of: providing a body having an open-porous foam structure and comprising at least a first metal or alloy; providing particles, each of which particles comprising at least a second metal or alloy; distributing the particles on the body; forming a structural connection between each of at least a subset of the particles and the body; and forming an oxide film on at least the subset of the particles and the body, wherein the oxide film has a catalytically active surface.

Abstract: A roof structure for an agricultural vehicle includes an upper roof assembly and a lower roof assembly connectable to the upper roof assembly. The lower roof assembly or the upper roof assembly includes a ventilation opening for guiding air-conditioned air and a circulation opening for supplying recirculated air. An air-guiding element is arranged between the lower and upper roof assembly. The air-guiding element is further disposed at the circulation opening and the ventilation opening such that a region sealed in relation to an external environment is formed.

Abstract: A roof structure for an agricultural vehicle includes an upper roof assembly, a lower roof assembly, and an air-conditioning chamber formed in the lower roof assembly. The upper roof assembly is connectable to the lower roof assembly to surround the air-conditioning chamber. An inlet chamber and an outlet chamber for air-conditioned air are provided such that the inlet chamber and the outlet chamber between the lower roof assembly and the upper roof assembly include chambers separated from each other. The structure also includes a circulation opening for supplying recirculated air arranged at the inlet chamber and an air-guiding element arranged in the inlet chamber, at the circulation opening, and at the air-conditioning chamber. A region is sealed in relation to an external environment.

Abstract: A control system controls a vehicle air-conditioning system including a cooling circuit having a compressor with a refrigerant that is supplemented with a compressor lubricant. The control system includes a control unit which controls the drive torque used for starting up the compressor. The control unit reduces the drive torque as a function of a determined time parameter that represents an elapsed compressor stoppage time (?T).

Abstract: Described is an air conditioning system with a heating function, wherein the inner heat exchanger is split in the air flow direction, wherein the first partial heat exchanger of the inner heat exchanger in the air flow direction preferably operates to cool the supply air, that is to say as a refrigerant evaporator, and wherein the second partial heat exchanger, which is connected downstream in the air direction, preferably operates to heat the supply air, that is to say as a refrigerant gas cooler, wherein the two partial heat exchangers of the inner heat exchanger can also both be used, in the case of the maximum cooling demand, as a refrigerant evaporator for cooling or can also both be used, in the case of the maximum heating demand, as refrigerant gas coolers for heating the supply air, and wherein in drying operation (reheat), the first partial heat exchanger of the inner heat exchanger in the air flow direction operates as a refrigerant evaporator and at the same time the second partial heat exchanger o

Abstract: A cooling system cools the air for a cab of a vehicle. The system includes a compressor and/or an evaporator, a condenser, an air guidance system and connecting lines. The condenser can be connected with the compressor or the evaporator by means of the connecting lines. Air for the cooling of the condenser can be conducted to the condenser by means of the air guidance system. The condenser installed in a limited or reduced construction volume and is located close to the cab without increasing the dimensions of the engine hood.

Abstract: The invention relates to a housing for an air conditioning system. There is a need for an air conditioning system housing which can be manufactured at low cost and which can withstand the higher pressures of an air conditioning system which uses CO2. The present invention provides a housing which includes walls and a woven reinforcing fabric consisting of plastic fibers. The walls are sheathed on their inner sides with the woven reinforcing fabric.

Abstract: An air quality monitoring arrangement is associated with an enclosed cab of an agricultural tractor used for towing or carrying spraying implements for treating crop with substances which might be toxic or otherwise harmful to people. A signal from a contaminant sensor is sent to a control arrangement which compares the actual sensed contamination of the air within the cab over time with a value from a performance map representing the performance expected from normal performance of the air circulating system of the cab. When the sensed contamination is higher than that of the performance map the operator is warned of a malfunction. The blower of the air circulating system may have its speed increased so as to pressurize the cab so as to exclude the entry of contaminated air through seals and other small openings of the cab.
