Embodiments of the present invention are directed to a customizable bio-manufacturing system which includes a manufacturing space having a first air handling system for providing supply air and a second air handling system for handling exhaust air, the supply air system being optionally provided with at least one of filtration, heating, cooling and or humidity control and a plurality of portable modules provided within the manufacturing space. At least one module having an interior capable of being interconnected with another module interior and each module's interior includes one or more components to perform at least one specific task of a biological, chemical, and / or pharmaceutical manufacturing process. At least one module includes an on-board environmental control system for controlling an environment within the module and a connection means for interconnecting the module interior with another module interior. The system also includes a central controller operating to at least perform one or more of operation and information collection for the operation of at least one of the system and one or more modules.

The invention is a battery powered source for an air handling system that provides subsurface aeration services when an available power source provides insufficient power. The system comprises a subsurface aeration duct, a motor, an air pump, a storage battery, a battery charger, and a control circuit responsive to commands. The control circuit is operatively coupled to the storage battery to control a connection of the storage battery to provide power to the motor. In response to a command, the control circuit connects the storage battery to provide power to the motor, and the storage battery provides sufficient power to operate the motor and air pump satisfactorily for operation of an air handling system used for subsurface aeration. The system further comprises a reversing valve to provide air under pressure with air flow in a first direction, and partial vacuum with air flow in a second direction.

A cooling system for providing conditioned air to a facility includes a chiller or other cooling subsystem, a cooling tower subsystem and one or more air handling units or process cooling units. The cooling subsystem may advantageously include one or more chillers (e.g., variable speed chillers, constant speed chillers, absorption chillers, etc.) and chilled fluid pumps. The cooling tower subsystem includes one or more cooling tower units and condenser fluid pumps. In some implementations, the air handling unit has a cooling coil and a variable volume fan. In some implementations, direct expansion (DX) cooling systems comprise compressors, evaporators and air-cooled, water-cooled or evaporatively-cooled condensing systems. Such systems can be controlled to reduce energy waste, improve occupant comfort and / or improve the thermal characteristics of the process cooling unit. The cooling system further comprises a control system which is configured to evaluate a cooling load value at the air handling unit and use the cooling load value to calculate at least one operational setpoint. The operational setpoint may advantageously be selected to improve the energy efficiency of the overall cooling system.

Disclosed is a packaged chilling system for providing chilled water to an air conditioning system for a building that includes: a duct system; an air handling system; and a water chilling system; wherein: the duct system is in operable communication with a building that has a plurality of rooms, at least one of the rooms having a sensor for detecting the room air temperature in the room, the duct system comprising at least one supply duct for directing low temperature air from the air handling system to the building and at least one return duct for directing high temperature air from the building to the air handling system; the air handling system includes a plurality of air handling units, each air handling unit comprising an air inlet for receiving high temperature air from the building, a cooling coil that includes at least one conduit through which chilled water flows, the cooling coil having multiple passes and positioned for heat transfer contact with the high temperature air, and a fan for increasing the velocity of air in the air handling unit; the water chilling system is installed at a location proximate the building, and is operably connected to the air handling system; and the water chilling system includes a moveable support structure comprising a support base on which a plurality of water chilling system components are affixed, the components including at least one water chiller for lowering the temperature of water from a high temperature to a low temperature. This packaged chilling system may also be used to provide chilled water to industrial processes such as chemical plants, automotive plants, textile mills, paper mills, computer cooling, and factory air-conditioning.

An upright surface cleaning apparatus comprises a support structure moveably connected to a surface cleaning head and having an air treatment member mounted to the upright section. The support structure is bendable and is operated by a remote actuator.

An air handling unit (AHU) for housing a number of components used in a heating or cooling system to provide forced air for climate control in a particular structure includes a single raceway construction having both low thermal conductivity and enhanced mechanical properties for use with lifting the AHU; a single insulated panel construction having a minimum number of components as well as enhanced mechanical properties for use as the floor in an AHU compartment; to minimize costs associated with fabrication and installation.
