Abstract: A system and method for sampling air at multiple locations in a controlled environment. The system and method includes automatic adjustment of mass flow rates and duration of vacuum connections (either via time elapsed or indirectly by volume) based on rates set by an operator. Additionally, the system and method enables users to monitor and control aspects of the system via network-connected devices. Additionally, the system enable a vacuum pump to be disconnected from power in response to a physical emergency button, a software-based emergency stop button available on network connected devices, and an automatic power disconnection in response to an abnormal mass flow reading that could potentially impact the vacuum pump.

Abstract: A Heating, Ventilating Air Conditioning (HVAC) fan control method comprising: detecting a HVAC fan is controlled by a fan-on setting, determining a HVAC fan-on operating time (F6) is greater than a Threshold Fan-on Time (TFT); and performing at least one action selected from the group consisting of: providing a HVAC fan-on alarm message, overriding the fan-on setting, and turning off the HVAC fan. The method may also include turning off an ultraviolet lamp after the HVAC fan is turned off, and turning on the ultraviolet lamp after the HVAC fan is turned on. Turning off the HVAC fan comprises: turning off the HVAC fan for a variable duration, skipping a scheduled fan-on setting, turning off the HVAC fan based on a call for cooling/heating, turning off the HVAC fan based on an indoor air quality measurement, and turning off the HVAC fan based on a geofencing or occupancy sensor signal.

Abstract: A condensate drain assembly includes a drain pan configured to receive condensate from an evaporator coil of an air conditioning system. The drain pan is configured to be removed from the air conditioning system. The condensate drain assembly also includes a drainage pipe configured to translate the condensate from the drain pan to a drain located beneath the air conditioning system and a drain pan end cap. The drain pan end cap includes a first aperture configured to drain the condensate from the drain pan and a second aperture configured to align with the drainage pipe.

Abstract: A terminal unit for a heating, ventilation, and/or air conditioning (HVAC) system may include a housing defining a mixing chamber. The mixing chamber may have a primary air inlet, a plenum air inlet, and a mixed air outlet, and mix a primary air flow from the primary air inlet with a plenum air flow from the plenum air inlet to form a mixed air flow that is output through the mixed air outlet to a conditioned space. The terminal unit may also include a panel adjustably coupled to the housing to adjustably occlude the plenum air inlet. The terminal unit may also include an actuator coupled to the housing and the panel to move the panel and adjust a size of an air flow path corresponding to the plenum air inlet.
