Abstract: A piping package is provided for connecting a heating, ventilation, air conditioning, and refrigeration (HVACR) system to a building variable air volume (VAV) system. The piping package includes an enclosure containing a supply pipe and a return pipe. Each of the supply pipe and the return pipe include an air vent and a blow-down valve. The piping package can be configured such that it is flip-able and can be positioned on either side of a main unit of the HVACR system. The piping package can further include a heat exchanger configured to exchange heat between the HVACR system and the process fluid distributed to the building VAV system.

Abstract: A method for fabricating assembled structures. The method includes providing a tip structure, which has a first end, a second end, and a length defined between the first end and the second end. The second end is a free end. The method includes attaching a nano-sized structure along a portion of the length of the tip structure to extend a total length of the tip structure to include the length of the tip structure and a first length associated with the nano-sized structure. The method includes shortening the nano-sized structure from the first length to a second length. The method also includes pushing the nano-sized structure in a direction parallel to the second length to reduce the second length to a third length of the nano-sized structure along the direction parallel to the second length to cause the nano-sized structure to move along a portion of the length of the tip structure.

Abstract: Embodiments in accordance with the present invention relate to techniques for the growth and attachment of single wall carbon nanotubes (SWNT), facilitating their use as robust and well-characterized tools for AFM imaging and other applications. In accordance with one embodiment, SWNTs attached to an AFM tip can function as a structural scaffold for nanoscale device fabrication on a scanning probe. Such a probe can trigger, with nanometer precision, specific biochemical reactions or conformational changes in biological systems. The consequences of such triggering can be observed in real time by single-molecule fluorescence, electrical, and/or AFM sensing. Specific embodiments in accordance with the present invention utilize sensing and manipulation of individual molecules with carbon nanotubes, coupled with single-molecule fluorescence imaging, to allow observation of spectroscopic signals in response to mechanically induced molecular changes.

Abstract: An air conditioning apparatus having a dehumidifying mode so that the apparatus is able to cool and dehumidify air in a space to be conditioned and also dehumidify air in the space with no sensible cooling of the air. The apparatus has both an evaporator and a heater. A solenoid operated stop valve allows hot refrigerant to flow through the heater when the valve is open. In its cooling mode, the apparatus operates much as a conventional vapor compression air conditioner, with the stop valve shut and no refrigerant flow through the heater. The stop valve opens to align the apparatus for its dehumidifying mode. In that mode, a portion of the hot refrigerant exiting the compressor discharge bypasses the outside condenser and flows through the inside heater.

Abstract: An air conditioning apparatus having a dehumidifying mode so that the apparatus is able both to cool and dehumidify air in a space to be conditioned and also to dehumidify air in the space with no sensible cooling of the air. The apparatus has two heat exchangers in its indoor section and two heat exchangers in its outdoor section. In its cooling mode, the apparatus operates much as a conventional vapor compression air conditioner, with both outside heat exchangers operating in series as a single evaporator. A four way reversing valve shifts to align the apparatus for its dehumidifying mode. In that mode, hot refrigerant is directed to one of the inside heat exchangers before reaching one of the outside heat exchangers that continues to function as a condenser. The cooled refrigerant bypasses the second outside heat exchanger before passing through the second inside heat exchanger that continues to function as a evaporator.
