20090148316 | Pump Device - The invention relates to a pump device for feeding a delivery medium out of a deep borehole which leads from a floor level into the interior of the earth, which deep borehole is provided at least in sections with borehole piping, having a pump and having a motor which drives the pump. As a result of the motor being arranged outside the borehole piping and as a result of it being possible for the motor to be connected to the pump by means of torque transmitting means which extend laterally through the borehole piping, the motor can be protected from overheating, and in the event of a fault, can be pulled out of the deep borehole independently of the pump. | 06-11-2009 |
20090205336 | Method and Device for the Transfer of Heat from a Heat Source to a Therodynamic Cycle with a Working Meduim of at Least Two Substance with Non-Isothermal Evaporation and Condensation - The invention relates to a thermodynamic circuit with a working medium comprising at least two substances with non-isothermal evaporation and condensation whereby the working medium can decompose above a given temperature. According to the invention, the heat from heat sources at temperatures above the decomposition temperature of the working medium may be made useful with little complexity and with high operational security, whereby the heat from the heat source is transferred in a first step to a hot liquid circuit and, in a second step, from the hot liquid circuit to the circuit with the working medium comprising at least two substances with non-isothermal evaporation and condensation. The heat introduced to the circuit with the working medium comprising at least two substances with non-isothermal evaporation and condensation can be reduced by means of the intermediate hot liquid circuit, such that a decomposition of the working medium can be avoided. Furthermore, the circuit with the working medium comprising at least two substances with non-isothermal evaporation and condensation is embodied as a standardized solution for use with differing heat sources each at differing temperatures, whereby matching to the temperature of the heat source is achieved by means of the intermediate hot liquid circuit. | 08-20-2009 |

20100326131 | METHOD FOR OPERATING A THERMODYNAMIC CYCLE, AND THERMODYNAMIC CYCLE - In a thermodynamic cycle with at least one first heat exchanger for creating a first heated or partially evaporated working medium flow by heating or partially evaporating a liquid working medium flow by heat transmission from an expanded working medium flow; a second heat exchanger for creating a second at least partially evaporated working medium flow; a separator for separating a liquid from a vaporous phase of the second flow; and an expansion device for creating an expanded vaporous phase, pressure pulsations are prevented during the start-up of the cycle in that the vaporous phase separated by the separator is conducted past the expansion device and the first heat exchanger. The liquid phase separated by the separator is cooled in the first heat exchanger by heat transfer to the liquid flow. After the first heat exchanger, the cooled, separated, liquid phase and the separated vaporous phase are brought together. | 12-30-2010 |
20110000205 | METHOD AND DEVICE FOR CONVERTING THERMAL ENERGY INTO MECHANICAL ENERGY - When converting thermal into mechanical energy by a working medium containing a mixture of at least two materials having different boiling and condensation points, which is fed to a condenser, and is condensed therein, the condenser condensation pressure may increase and the efficiency for generating the mechanical energy thus decreases because the mixture of materials is separated into a liquid phase and a vapor phase upstream of the condenser. To prevent this, the liquid phase of the working medium is mixed with the vapor phase of the working medium before or while the working medium is condensed, thus once again creating a homogeneous mixture of materials which condenses at a lower pressure than the separated working medium, thereby preventing loss of efficiency. This can be applied to the use of thermal energy from low-temperature sources such as geothermal fluids, industrial waste heat, or waste heat from internal combustion engines. | 01-06-2011 |
