Abstract: The present invention relates to a local thermal energy consumer assembly and a local thermal energy generator assembly to be connected to a thermal energy circuit comprising a hot and a cold conduit. The local thermal energy consumer assembly is selectively connected, via a pump or a valve to the hot conduit. The local thermal energy generator assembly is selectively connected, via a pump or a valve to the cold conduit. The use of either the valve or the pump is controlled by determining a local pressure difference between heat transfer liquid of the hot and the cold conduits.

Abstract: A furnace includes a pump in a circuit through a heat exchanger and a manifold having a plurality of discharge openings in a first area and return openings in a second area connected by a transfer area with each discharge and return feeding a respective heat loop. A bypass in the circuit includes a temperature controlled protection valve connected between the bypass and the manifold. The heated liquid inlet of the manifold is connected to the manifold in the first area with the plurality of discharge openings at a position between the plurality of discharge openings and the plurality of return openings. The manifold is defined by a rectangular chamber divided longitudinally and diagonally by a transverse wall which terminates at one end at a position spaced from an adjacent end of the chamber to define an undivided portion of the chamber at the end which forms the transfer area.

Abstract: A system and method of providing a high temperature hot water system assembly including a direct buried valve box that connects to one or more underground service pipes is disclosed. The buried valve box contains a valve assembly configured to control the flow of water through the one or more service pipes. An air gap within the valve box allows for movement and expansion of the components as the temperatures rise, preventing cracking or other failures. A bypass valve is also provided within the buried valve box, allowing for a small amount of hot water to flow through the service pipes to gradually increase the temperature. The direct buried valve boxes, controllable through valve risers that terminate in surface assembly boxes, eliminate the need for large, concrete underground vaults that make maintenance and operation of valve assemblies more difficult.

Abstract: The invention concerns a method for the recovery of thermal energy from a steam dryer 2 with a closed circulation 2.1 that produces excess steam SS characterized in that the excess steam SS is condensed to an unclean condensate UC in a steam regeneration unit 3 and in that thermal energy in the unclean condensate UC is recovered by being transferred to a district heating medium HW in a heat exchanger 4 for district heating. The invention concerns also a system for the recovery of thermal energy from a steam dryer 2 with a closed circulation 2.1.

Abstract: The present invention relates to a method of controlling pressure maintenance equipment for a cooling and heating system. More particularly, the present invention relates to a method of operating and controlling, under optimum conditions, pressure maintenance equipment with multiple sensors so as to check for irregularities in the sensors which measure the same physical parameter. In the present invention, measurement values of two or more sensors are used to detect whether an abnormality has occurred in any sensor. If a sensor is determined to be abnormal, a measurement value of the abnormal sensor is excluded when determining a reference control value. Thereby, the pressure can be precisely and reliably controlled in response to actual conditions of the system.

Abstract: A device, such as a heat meter for measurements of hot tap water energy usage, separated from building heating energy usage, in a district heating substation. The device is connected only to sensors attached to the supply pipe and return pipe of the district heating substation. A device, such as a heat meter, has a detector to detect a deviation in the total power (P) usage in the district heating substation which deviation depends on the use of warm tap water. The device may be used to calculate energy consumption in the heat exchanger related to building heating, and the energy consumption in the second heat exchanger related to tap water heating. The device may be used to calculate energy consumption for tap water heating, which relates to the duration of the deviation.
