Various embodiments of the teachings herein include a device for controlling a HVAC system of a room. The device may include: a memory storing a metamodel for a distribution of physical quantities of air in the room, the metamodel based on reduced order modeling of a plurality of executed simulations of the physical quantities for a first configuration of the room; and a processor programmed to determine a value of a first subset of the physical quantities at a certain location in the room using the metamodel and a set of measured values of each physical quantity being measured by a number of physical sensors.

Computerized device and computer-implemented method for controlling a HVAC system

A method for performing a simulation of a field having a subterranean formation is described. The method includes obtaining phase behavior data of subterranean fluids of the field, generating an equation of state (EOS) model of the fluids based on the phase behavior data, generating a Helmholtz free energy model that reproduces predictions of the EOS model over a pre-determined pressure and temperature range, and performing the simulation of the field using the Helmholtz free energy model. The method may further include reducing the EOS model to a reduced EOS model having a reduced number of components to represent the EOS model over a pre-determined pressure and temperature range, generating the Helmholtz free energy model based on the reduced EOS model, and obtaining and using phase behavior data of injection fluids used. A computer system data.

In a reduction unit of a drilling motor comprising a casing, input and output shafts installed on supports, a reduction gear including sun and crown wheels, pinion carriers and planet pinions with supports located in a circular space between the wheels, an oil-filled chamber and a system of oil protection, there is provided a means eliminating the overloading of the reduction gear and a means eliminating the effect of torque fluctuations on the operation of the reduction gear while the supports of the input and output shafts installed on the ends of said shafts connected with the reduction gear are made in the form of articulated units taking axial loads and permitting angular displacements of the shafts, each of said shafts carrying a seal installed side by side with said support at the side opposite to the reduction gear, said seal being provided with a dividing space filled with a buffer fluid which protects said seal against contact with the drilling fluid.

Reduction unit of drilling motor

A turbo-drill is provided with a mechanism for reducing the speed of rotation of the drilling bit, the mechanism being made in the form of a frictional reduction means wherein the rotors of the turbo-drill are the inner wheel and the stators of the turbo-drill are the outer wheel. Between the stators and rotors in the carrier of the reduction means disposed are bodies of rolling, which roll during rotation of the rotor under the action of contact frictional forces. In addition, between the reduction stages of the turbine and above them mounted are one or more auxiliary stages of the turbine, each having two wheels provided with vanes, one of the wheels being connected through its hub to the shaft so as to enable axial displacement thereof with respect to the shaft.
