Abstract: An HVAC system for controlling conditions in one or more grow rooms. The HVAC system includes pumps, sensors, controller(s) and valve(s) that mitigate undesired over cooling, which may result in thermally stressing the plants. To counteract the undesired overcooling the HVAC system utilizes reheat to return grow room temperatures to optimal conditions.

Abstract: A humidifier includes a water supply and a nebulizer bank having a plurality of ultrasonic nebulizers, where each of the plurality of ultrasonic nebulizers is in fluid communication with the water supply and is structurally configured for breaking up water in liquid form into aerosol droplets for humidifying a volume. The humidifier may further include a controller in communication with each of the plurality of ultrasonic nebulizers to selectively activate each of the plurality of ultrasonic nebulizers independently from one another, where the controller is configured to stage activation of one or more of the plurality of ultrasonic nebulizers while accounting for at least one of: (i) a time from startup to a production of an aerosol droplet for each ultrasonic nebulizer; (ii) a threshold power consumption for the humidifier; (iii) a temperature of a component of the humidifier; and (iv) a predetermined humidity of the volume.

Abstract: An air conditioning system includes a refrigeration cooling coil in fluid communication with process air, a refrigeration circuit containing refrigerant, a heat exchanger in fluid communication with the refrigerant and water, the heat exchanger adapted to transfer heat from the refrigerant to the water, a hot water coil in fluid communication with the water, a desiccant rotor having a process portion in fluid communication with the process air and a reactivation portion, and a reactivation blower adapted to move reactivation air over the hot water coil and through the reactivation portion of the desiccant rotor. A method of conditioning air is also described.

Abstract: An air handling unit for a computer room having a floor can include a cabinet having an upper chamber and a lower chamber separated by a partition. The lower chamber can be positioned in an air plenum located under the floor. The air handling unit can include a cooling device located in the upper chamber. A first fan assembly can include a first fan and a first mounting device coupling the first fan to the cabinet. The first fan assembly can be movable along a first axis between the upper and lower chambers. According to another embodiment, the air handling can further include a first sensor that detects air pressure in the cabinet, a second sensor that detects air pressure outside the cabinet, and a control unit that increases rotational speed of the fan when the air pressure in the cabinet is lower than the air pressure outside the cabinet.
