  • Publication number: 20120318000
    Abstract: A vehicle includes an air conditioning system for conditioning intake air flowing into a vehicle interior. The air conditioning system has a primary heat exchanger in thermal communication with a drive unit via a coolant circuit, a compressor, and a secondary heat exchanger which is disposed jointly with the compressor in a refrigerant circuit. The secondary heat exchanger operates as a condenser in a heating mode of the air conditioning system and jointly with the primary heat exchanger gives off heat to the intake air. A control device controls operation of the refrigerant circuit in response to an input by a user. The control device includes an evaluation unit to carry out a comparison between a desired heat supply commensurate with the input by the user and a determined actual heat supply, and generates an output signal for operating the compressor in response to the comparison.

  • Patent number: 7279602
    Abstract: Process for separating triethanolamine continuously by distillation from a mixture of monoethanolamine, diethanolamine and triethanolamine together with ethanolamine ethers and water obtained by reaction of ammonia with ethylene oxide in the liquid phase under superatmospheric pressure and at elevated temperature, in which the mixture is distilled in two stages. The low-boiling fraction and the high-boiling fraction are taken off and discharged in the first stage and the intermediate-boiling fraction comprising >99.4% by weight of triethanolamine and <0.2% by weight of diethanolamine is distilled in the second stage. The distillation of the mixture is preferably carried out in a first column and a second column connected to this or in a dividing wall column.
