Abstract: Method for operating a solar installation. The solar installation includes a solar field with direct evaporation accompanied by the generation of superheated live steam, a turbine for expanding the live steam, and a generator driven by the turbine for generating electrical energy. At least one valve is associated with the turbine by which the amount of live steam fed to the turbine is adjusted. The valve, or each valve, through which the amount of live steam fed to the turbine is adjusted such that an actual value of a live steam pressure occurring upstream of the turbine follows a reference value determined depending on a live steam temperature of the live steam upstream of the turbine.

Abstract: A device (10) for suspending gas channel elements, in particular for suspending guide blades or guide blade segments or gas channel segments, on a housing of a gas turbines is provided. The device comprises first plate-shaped elements (11, 12, 13, 14) and second plate-shaped elements (15, 16, 17), whereby the first plate-shaped elements (11, 12, 13, 14) and the second plate-shaped elements (15, 16, 17) are connected together by web-like elements (18) which extend in an essentially perpendicular manner in relation to the first and second elements and form a meandering or crenelated profile.

Abstract: An apparatus and method for active gap monitoring for a continuous flow machine, in particular an aircraft propulsion device, which has a rotor and a housing which surrounds the rotor forming a rotor gap, is disclosed. The apparatus having a cooling channel which is arranged on the external circumference of the rotor housing and is supplied with cooling air from a plenum. The cross section of the cooling channel decreases from the plenum in the circumferential direction. This ensures homogenous cooling and reduces the weight of the apparatus.

Abstract: A method for controlling evaporation temperature in an air conditioning system, especially an air conditioning system in a motor vehicle, comprising a latent cold accumulator which can be cooled by an evaporator (1). The evaporation temperature of a coolant is adjusted inside the evaporator (1) according to requirement to a value lying between a minimum temperature (T_min) and a maximum temperature (T_max) lying below the phase transition temperature of the latent medium.

Abstract: A coolant evaporator (1) has a heat transmission surface (3) provided for the transmission of heat from air to a coolant and a number of flow duct segments (2) provided for receiving the coolant. A storage capsule (6a, 6b) provided for filling with a heat storage medium is arranged between adjacent flow duct segments (2). The coolant evaporator (1) is especially suitable for a motor vehicle with an idle-stop function.

Abstract: A method is provided for controlling the evaporator temperature in a vehicle air conditioner having an evaporator, a compressor, a condenser and an expansion element, in which the evaporator temperature is adjusted as a function of operating conditions. An evaporator temperature control, in conjunction with an optimizing of consumption and comfort, is achieved in that a first evaporator temperature value (TV—F) is determined with respect to a desired air humidity, a second evaporator temperature value (TV—F) is continuously determined for ensuring a sufficient cooling capacity, and the lowest of the two evaporator temperature values is selected as the evaporator temperature (TV) to be set.
