An air flow system for a horticulture application is configured to facilitate simplified, reconfigurable air flow. Via use of adaptable and reconfigurable inlet ports, outlet ports, and a number and/or configuration of ventilation socks, the air flow system may be customizable to each respective application and/or produce increased plant density and/or health in horticultural applications.

Methods and apparatus to monitor environmental conditions and reduce condensation are disclosed. An example apparatus includes a first sensor system to measure a first temperature in a first area and a second sensor system to measure a second temperature in a second area adjacent to the first area. The first area being separated from the second area by a door. A controller has at least one memory, instructions, and processor circuitry to execute the instructions to at least: compare the first temperature and the second temperature; determine if a temperature difference between the first temperature and the second temperature exceeds a temperature threshold; and in response to determining that the temperature difference does not exceed the temperature threshold, deactivate a fan located in the first area.

A fan filter unit with an integrated heater system includes a housing comprising an air intake and an air outlet; a blower motor mounted within the housing and downstream of the air intake; a heater mounted within the housing and downstream of the blower motor; and an air filter mounted within the housing. In some cases, the system further includes an inner housing mounted to a top of an inside portion of the housing, the inner housing having an inner housing air outlet, where both the blower motor is mounted within the inner housing and the heater is mounted within the inner housing. In some of such cases, the air intake and the air outlet are positioned to direct an air flow vertically and the inner housing air outlet is positioned to direct an air flow horizontally.

The range hood unit includes a range hood transmitting unit configured to transmit information on an exhaust volume. The heat exchanging ventilation device (1) includes: a heat exchanger receiving unit (19) configured to receive the information from the range hood transmitting unit; and a heat exchanger control unit (17) configured to determine the operation of the heat exchanging ventilation device (1), based on the information received by the heat exchanger receiving unit (19). Based on the exhaust volume of the range hood unit that has been received by the heat exchanger receiving unit (19), the ventilation system exhausts air by subtracting the exhaust volume of the range hood unit from an exhaust volume equivalent to the air supply volume of the heat exchanging ventilation device (1).

Embodiments of the present disclosure include a drive belt tensioner configured to adjust tension in a drive belt of a blower assembly for a heating, ventilation, and/or air conditioning (HVAC) system. The drive belt tensioner includes a mounting bracket configured to couple directly to a blower housing that is configured to house a blower of the blower assembly. The drive belt tensioner further includes an idler pulley configured to contact the drive belt. A position of the idler pulley is adjustable relative to the mounting bracket to enable adjustment of the tension in the drive belt.
