Systems and methods for integrating a building management system communicatively coupled to a security subsystem via a communication network, in which the building management system determines occupancy data, with a heating, ventilation, and air conditioning subsystem that includes a scrubber unit communicatively coupled to the building management system via the communication network. The scrubber unit includes a contaminant filter that sorbs air contaminants from a surrounding environment when an elevated pressure differential is introduced across the contaminant filter; an inlet sensor that determines sensor data indicative of contaminant level present in return air received by the scrubber unit from an internal portion of the building; and scrubber control circuitry that selectively instructs the scrubber unit to operate in one of multiple regeneration modes based at least in part on the occupancy data and the sensor data to facilitate improving filtering efficiency provided by the contaminant filter during subsequent operation.

HVAC scrubber unit with building management system integration systems and methods

A contaminant scrubber of a heating, ventilation, and air conditioning (HVAC) system includes a housing having a first side wall and a second side wall opposite to the first side wall. The contaminant scrubber also includes a first compartment formed within the housing, a second compartment formed within the housing and having a cartridge set removably disposed therein, and a third compartment formed within the housing, where the second compartment is positioned between the first compartment and the third compartment. The contaminant scrubber also includes a first cross-member beam extending along a first bottom end of the first compartment and a second top end of the second compartment, where the first cross-member beam extends from the first side wall of the housing to the second side wall of the housing. The contaminant scrubber also includes a second cross-member beam extending along a second bottom end of the second compartment and a third top end of the third compartment, wherein the second cross-member beam extends from the first side wall of the housing to the second side wall of the housing.

Contaminant scrubber of an HVAC system

System and methods for improving implementation of a scrubber unit in a heating, ventilation, and air conditioning system. The scrubber unit includes a housing that house a plurality of filter cartridges, which each includes a chemical compound that facilitates sorbing air contaminants. The housing includes a first sidewall and a second sidewall. The scrubber unit includes an internal wall enclosed within the housing, a cross-member coupled between the first sidewall and the second sidewall perpendicular to the internal wall, and a contaminant filter that includes the plurality of filter cartridges coupled between a top cartridge deck and a bottom cartridge deck, in which the bottom cartridge deck is coupled to the cross-member when the contaminant filter is completely enclosed within the housing to facilitate reducing likelihood of the bottom cartridge deck deforming under weight of the plurality of filter cartridges.

HVAC scrubber unit mechanical improvement systems and methods

Systems and methods for improving operation of a heating, ventilation, and air conditioning system, which includes a scrubber unit coupled to an air handling unit via a return air conduit. The scrubber unit includes a contaminant filter, which sorbs air contaminants from a surrounding environment when at a target pressure differential and releases previously sorbed air contaminants into the surrounding environment when at target temperature, a return inlet actuator coupled to a return inlet damper, and scrubber control circuitry programmed to determine parameters of outside air and instruct the return inlet actuator to ramp the return inlet damper from a closed position to an open position during a bleed phase of a regeneration cycle to enable venting of the previously sorbed air contaminants using return air when the parameters of the outside air are not within corresponding target parameter ranges.

HVAC scrubber unit operational control systems and methods

Systems and methods to facilitate controlling operation of a scrubber unit implemented in a heating, ventilation, and air conditioning system. The scrubber unit includes a scrubber housing, which encloses a contaminant filter; and a control panel coupled in a sidewall of the scrubber housing. The control panel includes a controller module, which includes a first module housing that encloses scrubber control circuitry and a first plurality of input/output ports. The scrubber control circuitry communicates with first equipment in the scrubber unit via the first plurality of input/output ports. The control panel includes an input/output module, which includes a second module housing that encloses a second plurality of input/output ports; and a communication bus coupled between the controller module and the input/output module that enables the scrubber control circuitry to communicate with second equipment in the scrubber unit via the second plurality of input/output ports.
