摘要： A method for operating a control valve using an HVAC actuator is described, the method comprises a circuit of the HVAC actuator executing the steps of: monitoring (S1) a rotation angle (ϕ) associated with a drive torque (Mdrive) applied by the HVAC actuator for moving the valve member; detecting (S2) a blocking of the control valve, if the applied drive torque (Mdrive) effects a change of the rotation angle (Δϕ) which is smaller than a threshold angle (ϕth); upon detection of the blocking, controlling the HVAC actuator to repeatedly change the applied drive torque (Mdrive) between a first torque value (M1) and a second torque value (M2); and controlling the HVAC actuator to periodically modulate (S4) the first torque value (M1) between a third torque value and a fourth torque.

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： 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 control valve (2) for regulating a fluid flow in an HVAC comprises a valve body (21) and a temperature sensor (25) configured to measure the temperature of a fluid (24) flowing within the control valve (2). The temperature sensor (25) is arranged such that the temperature sensor (25) is essentially thermally decoupled from the valve body (21).

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： The invention relates to a control apparatus (3) for an HVAC system (5), wherein the control apparatus (3) has a communication module (33) for communicating with one or more components of the HVAC system (5). The control apparatus comprises a passive NFC transponder (34), which is set up to receive and store a unique identifier (341) of each of the one or more components from a mobile service apparatus (2) before a power supply for the control apparatus (3) is switched on, and a control module (35) which is set up to access stored identifiers (341) after a power supply for the control apparatus (3) has been switched on and to transmit control signals to components determined by the identifiers via the communication module (33). The invention also relates to a mobile service apparatus (2) and to components in the form of drives (1), sensor apparatuses, regulators, operating devices and/or communication devices of the HVAC system (5).

摘要： An actuator (1) comprises an electric motor (11) for moving an actuated part (2) to an actuated position. The actuator (1) further comprises a controller (10) connected to the electric motor (11) and configured to determine a motor current of the electric motor (11) and to detect motor rotations. The controller (10) is further configured to determine the actuated position by counting the motor rotations detected while the motor current is at or above a current threshold indicative of a load torque, and by not counting motor rotations detected while the motor current is below said current threshold.

摘要： A control valve having a closing element, mounted in a housing between an inlet side and an outlet side and rotatable about an axis between a first and second end positions, and a passage channel through the closing element perpendicularly with respect to the rotational axis. The channel has inlet and outlet openings and connects the inlet side to the outlet side in the first end position, disconnects the inlet side from the outlet side in the second end position, and permits an increasing throughflow of a medium during the transition from the second end position into the first end position with a characteristic curve. Low valve noise is achieved because of the shape, size and configuration of the inlet and outlet openings of the passage channel and the configuration of walls of the passage channel without steps and edges.
