Abstract: A heating appliance for railway vehicles has at least one heating unit, forming a load-bearing sandwich structure together with edge profiles and a core layer. According to the invention, a plurality of heating units and sandwich structures are provided, each forming modular construction units, and the construction units can be positioned and fixed relative to one another in the railway vehicle by means of connecting elements.

Abstract: A method for heating ambient air for a passenger compartment of a motor vehicle is disclosed herein. The method includes the step of positioning a first heat exchanger proximate to a passenger compartment of a vehicle. The method also includes the step of passing ambient air for the passenger compartment through a first heat exchanger. The method also includes the step of concurrently directing distinct flows of engine coolant and steam to the first heat exchanger to heat the ambient air.

Abstract: A heating system for heating a tanker-trailer, including a housing, a fuel tank, a heating unit, fuel lines connecting the fuel tank to the heating unit, hot and cold water lines, connected at one end to the heating unit and at their other end to the tanker-trailer, and a control apparatus for controlling the flow of fuel from the fuel tank to the heating unit, water flow to and from the tanker-trailer, and the temperature of the water.

Abstract: A jet pump, in particular for hot-water heating systems or water-heating systems with return-flow mixing has a feeder head which is connected with a housing containing the receptor nozzle 13. The housing (7) contains a mixing tube (14) which is connected via a diffuser if needed with a second line connection (12), is coaxial with an injector nozzle (10) and adjoins the receptor nozzle (13); the mixing tube (14) also extends longitudinally through a chamber (22) of the housing in which at least a third line connection (18) and, if desired, a fourth line connection (19), directed respectively transversely to the mixing tube, discharges.In order to attain, e.g.

Abstract: A cabin heating arrangement is associated with an evaporative type engine cooling system and arranged so that immediately after a cold engine start when the cooling circuit of the engine is completely filled with liquid coolant coolant is inducted from a first port located immediately adjacent the most highly heated structure of the engine and pumped through the core of the cabin heater. Upon the coolant temperature rising sufficiently, coolant vapor is inducted from a second port located above the first one and introduced into the heater core.

Abstract: Herein disclosed is an improved passenger room heating system for use with a boiling liquid type engine cooling system. A coolant inlet tube of the heater core of the passenger room heater is connected to the coolant jacket of the engine through parallelly arranged two coolant outlet ports which are formed in the engine proper. One of the outlet ports is positioned above the other when the engine is properly mounted in a vehicle. A thermally operable valve is associated with the junction portion of the two outlet ports so that when the temperature of the coolant is higher than a predetermined degree, the upper outlet port is closed and the lower outlet port is opened, while, when the temperature of the coolant is lower than the predetermined degree, the upper outlet port is opened and the lower outlet port is closed.

Abstract: In a method for the regulated transfer of heat from a primary steam network to a heat consumer, the supply flow of which is at a predetermined overpressure and the return flow of which is at a relatively lower pressure, the steam withdrawn from the steam network in accordance with the heat consumption on the part of the consumer is cooled down to the point of condensation by the withdrawal of heat by means of a secondary medium, while a predetermined overpressure relative to the supply pressure of the heat consumer is maintained. The overpressure in a jet pump is then reduced to the supply pressure of the heat consumer, generating a corresponding driving force for the supply flow, and secondary medium heated up in the course of the cooling down of the steam is mixed with the supply flow.

Abstract: In a method for the regulated transfer of heat from a primary steam network (010), the flow (04) of the heat consumer (2) is supplied at a predetermined excess pressure, while the return flow (02) is at a relatively lower pressure.
