Patent SE-515812-C2 (SE)
Inventor: LINDGREN MATTS
IPC: F24D19/10
Filed: 1999-11-04
Abstract: A procedure and device for controlling the temperature of at least one outbound secondary flow (2u) in a secondary circuit from a heat exchanger (1) by means of a primary flow (3) in a primary circuit, via a regulatory member (5, 11) that regulates the primary flow, influenced by a control unit (7). The enthalpy difference ( DELTA h) between the inbound primary flow (3i) to the heat exchanger (1) and the outbound primary flow (3u) from the heat exchanger (1) is determined. The secondary flow (2i) is determined. The flow (3i) in the primary circuit (3) is determined, and the parameters determined above are supplied to the control unit (7) for controlling the regulatory organ (5, 11), whereby the primary flow (3) is controlled in dependence of the secondary flow (2), so that the power supplied to the heat exchanger through the primary flow (3) substantially equals the sum of, partly, the power needed to raise the temperature of the secondary medium from the current initial temperature Tsec_in to the desired outbound temperature Tsec_out_desired, and, partly, the assumed power requirement for compensating for the energy stored in the heat exchanger (1), and, partly, the assumed leak power from the heat exchanger (1). The invention also relates to a method for measuring power and heat quantity yielded by the primary medium.

Abstract: The device (100) has a circuit (200) furnished with a connecting circuit. A binary code word which specifies an absolute position is formed from the scanning signal of a scanner within the circuit. The coded word is introduced into an output circuit (300). Based on the command of a data processor (400), the output circuit transmits a serial code word through a data conductor (500). Two memory units (800,900) store the characteristic parameter of the position measuring device. The parameter is transmitted to the processing unit through the conductor. The memory (800) stores a decoding command of the processing unit. The decoding command similar to the binary data word is introduced serially into the position measuring device through the conductor. A digital scanning signal bypasses a connecting logic circuit and is introduced into the processing unit.

Трубчатый элемент-перемычка из пластичного, способного к пластической деформации, стойкого к коррозии материала, например латуни или нержавеющей стали, имеет два трубчатых концевых участка, расположенных в противоположных направлениях от промежуточного трубчатого участка, имеющего наружный диаметр, превышающий наружный диаметр концевых участков, и внутренний диаметр, превышающий внутренний диаметр указанных концевых участков. Концевые участки окружены фланцами. Вначале наружный диаметр концевых участков меньше, чем внутренний диаметр облицовочных труб. Таким образом каждая облицованная труба может устанавливаться на соответствующие концевые участки, при этом промежуточный участок занимает комбинированное расточенное отверстие. Инструмент, работающий изнутри, расширяет в радиальном направлении концевые участки, чтобы прижать пластмассовые облицовочные трубы к наружным трубам на величину в пределах от 8 до 30% толщины стенки облицовочных труб. Прилегающие концы наружных труб свариваются вместе. Наружная поверхность промежуточного участка может иметь расположенный на ней теплоизоляционный материал.
