摘要： A laser machine for machining workpieces has a workpiece support that forms a support main plane and is permeable to air perpendicularly to the support main plane. Supply air is directed to an upper side of the workpiece support. Air that is contaminated due to machining is discharged as exhaust air from the upper side of the workpiece support through the workpiece support to the bottom side of the workpiece support. In order to generate a laminar supply air flow which is perpendicular to the upper side of the workpiece support, the flow cross section of the supply air channel is divided into partial cross sections by partial cross sectional walls.

摘要： An HVAC actuator configured to actuate an HVAC component may include a rotatable output shaft having a range of rotation between a first end position and a second end position, a drive mechanism configured to selectively drive the output shaft, and a housing for housing the drive mechanism. The HVAC actuator may include a position indicator viewable from a front side of the housing that moves as the output shaft is rotated such that the position indicator indicates a current position of the output shaft. The position indicator may include an indicator wheel that is directly coupled to the output shaft of the HVAC actuator and may rotate with the output shaft. The indicator wheel may have one or more markings that move with the indicator wheel. The one or more markings may include a line extending in a radial direction from a rotation axis of the indicator wheel.

摘要： An energy recovery ventilator for a heating or cooling system includes a housing and a heat exchanger located in the housing for recovery of thermal energy from a stale airflow of the heating or cooling system. An exhaust fan positioned in the housing is in flow communication with the heat exchanger to urge the stale airflow from a return port disposed in a first side panel of the housing, across the heat exchanger and toward an exhaust port of the energy recovery ventilator. The exhaust fan and the heat exchanger are configured such that the heat exchanger is removable from the housing via a front panel opening in the housing without disturbing a position of the exhaust fan.

摘要： A monitoring system for a heating, ventilation, or air conditioning (HVAC) system of a residential or commercial building includes an evaporator unit device and four temperature sensors. The evaporator unit device includes an electrical sensor that measures current supplied to a circulator blower of the HVAC system. The measured current from the first electrical sensor is used to diagnose a problem with the circulator blower. The first temperature sensor that measures a temperature of refrigerant flowing between a condenser of the HVAC system and an expansion valve of the HVAC system. The second temperature sensor measures a temperature of refrigerant flowing between an evaporator and a compressor. The third temperature sensor measures a temperature of air flowing away from the evaporator. The fourth temperature sensor measures a temperature of air flowing toward the evaporator. The evaporator unit device transmits sensor data to a remote monitoring service over a data network.
