摘要： A control adapter for fastening on a HVAC device includes a wireless communication interface for communicating control signals between a remote control device and the control adapter. A wireless near-field communication interface communicates control signals between the control adapter and the HVAC device. A control circuit converts the control signals received from the wireless communications interface into the control signals of the wireless near-field communication interface and converts the control signals received from the wireless near-field communication interface into control signals of the wireless communication interface.

摘要： An air handler unit (AHU) in communication with a building automation system (BAS) or through direct programming of one or more smart valves within the AHU operates to meter an amount of water that flows through a coil in the AHU. In one embodiment, the BAS transmits a temperature setpoint signal to the smart valve and allows the smart valve to control its valve position without additional input from the BAS. In another embodiment, the AHU includes a master smart valve and a second valve. The BAS provides the temperature setpoint signal to the master smart valve, which in turn provides another temperature setpoint signal to the second valve. The second valve may take the form of a slave smart valve or a slave non-smart valve.

摘要： A device for measuring a volume flow in a ventilation pipe (1) comprises a sensor element (13) disposed on the mounting (8) and configured as a thermal anemometer. Upstream of the sensor element is a turbulence-generating element, which is configured and disposed at a distance from the sensor surface (18.1) such that highly turbulent flow is generated in the region of the sensor surface in a targeted manner. Downstream of the sensor surface is a flow element (20), which widens in the cross-section thereof in the flow direction (L), wherein starting from a height level of the sensor surface a height is reached that is greater than the height of the break-away edge (17.1) opposite the sensor surface.

摘要： To balance (S3) a group of consumers in a fluid transport system in which each consumer is provided with a motorized control valve for regulating the flow through the consumer, characteristic data for the consumers is stored (S2) which determines a valve position of the relevant control valve for target flows through one of the consumers in each case. A current total flow through the group of consumers is determined by means of a common flow sensor (S32) and a balance factor (S34) is defined on the basis of the current total flow and a sum of the desired target flows through the consumers. The consumers are dynamically balanced by setting (S31) the valve settings for the corresponding control valves on the basis of the characteristic data and the balance factor.

摘要： A method for operating a heat exchanger, through which a heat transfer medium flows on a primary side, entering the heat exchanger with a first temperature and exiting the heat exchanger with a second temperature. The heat transfer medium emits on a secondary side a heat flow to a secondary medium flowing through the heat exchanger in the case of heating or, in the case of cooling, absorbs a heat flow from the secondary medium which enters the heat exchanger with a third temperature and exits the heat exchanger again with a fourth temperature. The heat exchanger is capable of transferring a maximum heat flow. At least three of the four temperatures are measured and the respective saturation level of the heat exchanger is determined from these measured temperatures and is used for controlling the operation of the heat exchanger.

摘要： A hydraulic network (1) having plural parallel zones (Z1, Z2) with a regulating valve (V1, V2) in each zone for regulating a flow of fluid (φ1, φ2) through respective zones. Characteristic parameters of the hydraulic network (1) include static flow capacity values (Kex,a, Kex,b) of the zones. Measurement data sets are recorded which include a determined value of a hydraulic system variable of the hydraulic network (1), e.g. the total flow (φtot) or the system pressure (ΔP), and valve positions of the regulating valves (V1, V2) set for the determined value of the hydraulic system variable. The characteristic parameters are calculated from plural measurement data sets, by grouping related measurement data sets, which include the same value of the hydraulic system variable but different valve positions, and by using the flow capacity (Kvalve,a, Kvalve,b) of the regulating valves (V1, V2) at the valve positions included in the data sets.

摘要： An actuator (1′) for driving a regulating element (30) for controlling a fluid flow in a flow channel (29) includes an electric motor (4) for driving the regulating element (30) and a control unit (2) for controlling a current provided to the electric motor (4). A resistive element (3) including a resistor (5) and a NTC thermistor (6) connected in parallel across the resistor (5) is positioned in a current path from the control unit (2) to the motor (4). Accordingly, when the ambient temperature increases, the decreasing resistance of the resistive element (3) counterbalances the increasing resistance of the motor windings, resulting in a less varying current from the control unit (2) to the motor (4) and therewith in a less varying output torque of the motor (4).
