Abstract
An HVAC actuator (1) comprises a motor (12), a motor controller (13) coupled to the motor (12), and a heating apparatus (14) thermally coupled to the HVAC actuator (1). The HVAC actuator (1) further comprises a condensation controller (15) coupled to the heating apparatus (14). The condensation controller (15) is configured to monitor at least one condensation parameter, and to control the heating apparatus (14) using the at least one condensation parameter.
Claims10
An HVAC actuator (1), comprising:
- a motor (12);
- a motor controller (13) coupled to the motor (12);
- and
- a heating apparatus (14) arranged inside the HVAC actuator (1) and thermally coupled to the HVAC actuator (1);
- wherein the HVAC actuator (1) further comprises a condensation controller (15) coupled to the heating apparatus (14);
- the condensation controller (15) being configured to monitor at least—two condensation parameters inside the HVAC actuator (1),
- wherein the HVAC actuator (1) further comprises a sensing device (17) arranged inside the HVAC actuator (1) configured to detect the at least two condensation parameters inside the HVAC actuator (1),
- wherein the HVAC actuator (1) further comprises a memory unit (16) configured to store a set of condensation thresholds as tables or as functions, wherein the set of condensation thresholds relate to a dew point inside the HVAC actuator (1),
- wherein the condensation controller (15) is configured to select a condensation threshold, from the set of condensation thresholds stored in the memory unit (16) using at least one of the two detected condensation parameters, and
- wherein the condensation controller (15) is configured to compare the at least one of the two detected condensation parameters to the selected condensation threshold, and to control the heating apparatus (14) using at least one of the condensation parameters and the selected condensation threshold in accordance with the comparison to avoid condensation inside the HVAC actuator (1).
