摘要： A hydronic distribution system includes self-regulating valves networked together and operable to share valve temperature and valve position information with a microprocessor or other type of controller. The microprocessor runs one or more algorithms that process the temperatures and positions of the valves and then computes a desired speed for one or more variable speed pumps within the system. Controlling the pumps to operate at the desired speed and still maintain the correct amount of process fluid flow needed by the system reduces the overall energy use of the hydronic distribution system, saves on the operational lives of the pumps, and increases system efficiency.

摘要： A hydronic heating system employing comprises a water line, two or more boilers, and a control. In operation, the water line facilitates a circulation of water through a building and the boilers heat the water as the water flows through the water line. The control calculates a system energy load for operating boilers. The calculation of the system energy load is a function of a set-point water temperature for the hydronic heating system, a supply water temperature of water flowing relative to a supply point of the water line, a return water temperature of water flowing relative to return point of the water line and a flow rate of water flowing relative to a flow sense point of the water line.

摘要： A demand based control for a hydronic heating system varies the heat response based on an actual demand of the conditioned space, rather than an estimated thermal loss. Differences between supply and return of a heat transfer medium, such as forced hot water, are measured for the conditioned space, as well as the flow rate of the forced water to determine an actual thermal transfer to the conditioned space. A required heat generation is computed based on the measured transfer and resultant temperature change of the conditioned space, and heat generation parameters such as boiler firing rate and circulator pump speed varied to control the heat transfer to the conditioned space and avoid overshoot or excessive heat generation beyond that needed for the measured demand.

摘要： It is possible to realize flow rate control regardless of the scale on a load side or a piping system and to achieve energy saving. In a host control device (20) of a heat source system, a bypass valve opening command value is determined by an opening command value determination unit (22) such that a header differential pressure matches a target differential pressure value, and a target opening value according to the header differential pressure or the behavior of the bypass valve opening is set by a target opening value setting unit (24). A heating medium flow rate set value is determined by a heating medium flow rate setting unit (23) using the target opening value set by the target opening value setting unit (24) and the opening command value determined by the opening command value determination unit (22).

摘要： A method for operating a fluidic pipeline system including an active component generating a volume flow of a medium in the system is provided. A plurality of flow channels are connected in parallel with each other and supplied jointly with the volume flow of the medium by the active component. Each flow channel has an individual volume flow requirement of the medium, the requirement is variable over time for at least part of the flow channels. The volume flow in each flow channel includes a time-variable volume flow requirement individually throttled as a function of a control variable associated with the flow channel. The volume flow generated by the active component is additionally regulated as a whole so that no individual throttling of the local volume flow is required in at least one of the flow channels.
