  • Publication number: 20180335224
    Abstract: A packaged terminal air conditioner unit (PTAC) and methods for operating the same are provided. The PTAC includes an auxiliary fan positioned adjacent a vent aperture defined in a bulkhead of the PTAC. A control system includes an occupancy identification source including data indicative of a room occupancy status, such as the number of room occupants. An occupancy reader is configured for reading the occupancy identification source to determine the room occupancy status and a controller selectively operates the auxiliary fan based at least in part on the room occupancy status determined by the occupancy reader.

  • Publication number: 20180335223
    Abstract: A packaged terminal air conditioner unit (PTAC) and methods for operating the same are provided. The PTAC includes an auxiliary fan configured for urging a flow of make-up air from the outdoor portion into the indoor portion through a vent aperture defined by a bulkhead. A vent door is positioned proximate the vent aperture and is operatively coupled with a reed switch assembly. A controller is configured for stopping the operation of the auxiliary fan when the reed switch assembly detects that the vent door is in the closed position.

  • Publication number: 20180283864
    Abstract: The inventive concept presented is a trench slope angle tool and the method for using the slope angle tool during the excavation of a trench in a particular type of soil. In essence the slope angle tool is a planar, hand-held sighting device having a handle integrally attached to a Y-shaped component. The device may be utilized by a construction worker or project supervisor (the “user”) at a trenching worksite. The user visually superimposes the slope and banks of the trench against the contours of the slope angle tool to determine compliance with government-regulated excavation standards. Other important construction safeguards and govemmentally-regulated standards are also displayed on each face of the slope angle tool. In this manner, the correct trench sidewall slope, “spoil” pile locations, and other safety requirements can be readily observed to determine whether these elements are in compliance with the governmental regulations.

  • Publication number: 20180051908
    Abstract: A water heater tank has several components formed of a one-piece seamless construction. The water heater tank includes a cylindrical wall with inner and outer surfaces. A helical condenser channel may be formed in the outer surface of the cylindrical wall. The water heater includes a cold water inlet. A cold water channel may be formed in the inner surface of the cylindrical wall in fluid communication with the cold water inlet and the interior volume of the tank.

  • Patent number: 9862628
    Abstract: In a submerged membrane bioreactor (MBR or SMU), diffusers are used to eject air bubbles, primarily to facilitate the movement of mixed liquor past the membrane surfaces, cleaning and scouring the surfaces of the membranes with the mechanical energy of the combined air/liquid/solids movement. Oxygen transfer from the bubbles into the mixed liquor is often a secondary goal, for supplying oxygen to biological processes. The invention involves the use of a specific bubble diffuser, oriented at a selected upward angle, to enable a single style diffuser to accomplish simultaneous generation of mid-size and fine bubble aeration, with adjustment of the tilt angle varying the percentages of mid-size and fine bubble aeration. The angle selection, along with the number of diffusers and air volume selected, allows achievement of target liquid movement through the MBR.

  • Publication number: 20170146268
    Abstract: The present subject matter provides chiller apparatus including a storage tank for storing the liquid and a refrigerant cooling system. The refrigerant cooling system includes a compressor attached to the storage tank, a condenser positioned downstream from the compressor to condense a refrigerant received therefrom, and at least one evaporator positioned downstream of the condenser and wrapped about the outer surface of the storage tank. The evaporator includes a negative pitch coil configured to direct refrigerant flow from a position near a top of the storage tank to a position near a bottom of the storage tank.

  • Patent number: 9632142
    Abstract: Feedback from a solenoid is achieved by adding at least one variable resistance in parallel with the solenoid current feedback circuit for position detection. The resistance has current flowing therethrough when a switching device actuated by the solenoid is in one position or transitions from one position to at least one other position. A feedback current may be measured in the current feedback circuit and the position of the switching device in response to actuation thereof by the solenoid may be determined from the measured feedback current.
