摘要： Premix furnace for heating an occupied space while producing lower NOx emissions and methods of mixing air and fuel delivered to a premix burner and of improving combustion stability. A mixing device may be located within an inlet tube, may have a flat surface that is perpendicular to the direction of fuel flow, or may have two surfaces held at substantially opposite angles to induce swirl. A mixing device may be attached to the fuel injector, may be made from a piece of sheet metal, and may have bends and a hole for attachment to the fuel injector. A fluidic diode in the inlet tube may improve combustion stability and may include a hollow frustum or a frustoconical portion, a cylinder concentric with the inlet tube, or a combination thereof. Some embodiments include refractory insulation lining the combustion chamber or may adjust for elevation or fuel characteristics.

摘要： Airflow rates within a ventilation system are controlled using motor spee d or torque and motor electric current or pressure. Fan speed or torque may be varied to compensate for differing restriction in ductwork, and may provi de a constant airflow rate over a range of varying airflow restriction. Air handlers or air conditioning units may be mass produced in common configurat ions, and installed in different buildings or structures with different duct work configurations. Methods operate a fan motor at a present speed or torqu e, sample speed or torque, sample current of the fan motor or pressure withi n the ventilation system, calculate a present airflow rate within the ventil ation system, calculate a new input setting using the present airflow rate a nd a target airflow rate, change the speed or torque to the new input settin g, and repeat these steps to converge on the target airflow rate, often avoi ding overshoot.

摘要： A furnace utilizing, in the upper portion of its cabinet, a blower acting downward through a separator opening to circulate room air past a combustion chamber whose gases flow upward through a sideward-positioned board radiator member which reaches up to the flue. A substantial increase in efficiency results from drawing the combustion gases out of the combustion chamber at the side opposite to the lower end of the broad radiator member, and interposing therebetween, directly beneath the separator opening, a plurality of tubes which serve as an intermediate heat exchanger. A still greater increase in efficiency is achieved by utilizing, instead, a finned tube heat exchanger across and beneath said separator opening; its heat transfer may be so great as to result in condensation of water vapor in the combustion gas. To purge this, a motorized inducer-blower is used in the inlet air system, driving the condensate through the finned tube heat exchanger to an appropriate drain.

摘要： SELF-ADJUSTING TELESCOPING CONCENTRIC FLUE ASSEMBLY A self-adjusting, telescoping concentric -flue assembly provides non-separating, substantial flexibility between the telescoping sections of both the flue and the air supply ducts. The lower flue and air supply ducts may move radially independently of each other sufficiently to permit installation even on a furnace having somewhat non-concentric flue and air inlet connections. Attachment of the lower air supply duct to the furnace insures that the lower flue is likewise attached, yet the lower air supply duct can be raised independently of the lower flue to check the connection of the latter with the furnace flue connection.

摘要： UNI-DIRECTIONAL FIN-AND-TUBE HEAT EXCHANGER A fin and-tube heat exchanger designed for one-way airflow, in which louvers, formed from the fin stock, progressively increase in length from the fin leading edge to its trailing edge. Their end walls channel air into stagnant air spaces behind the tubes. The tube collars may be offset somewhat toward the fin trailing edge, further reducing the stagnant air zones. In -those bent heat exchangers in which air flows in from outside the curve, offsetting the collars also lessens the angular convergence of fin trailing edges inside the curve and presents less resistance to airflow.

摘要： ELECTRIC RESISTANCE HEATER AND LIMIT SWITCH ASSEMBLY A heater and limit switch assembly, particularly useful for installation in the conditioned air duct of a rooftop air conditioner. The loop of a rigid-loop heater, mounted on a vertical plate by two parallel legs, is modified to provide an inward offset portion leading to the second leg. Radiation, from the offset portion and its bend into the second leg, is received at close range by a simple disk-type limit switch, positioned on the plate outward of the second leg and facing the offset, inducing prompt response to any increase over design temperature.

摘要： CEILING DISTRIBUTOR DUCT ASSEMBLY FOR ROOFTOP AIR CONDITIONERS A low profile ceiling duct assembly to be used with rooftop air conditioners. The unit combines an octagonal sheet metal ceiling plate which provides the upper portion of a plenum chamber; this extending into the roof space above a ceiling opening. The lower plenum portion is provided by the molded plastic octagonal air distributor box, mounted against the edges of the plate and extending into the room space sufficiently to afford air flow sidewardly outward from the plenum. The air distributor box has outlet grilles at alternate sides of the octagon. They discharge air in four directions along the ceiling line while return air is drawn centrally upward.

摘要： Heat pumps that heat or cool a space and that also heat water, refrigerant management systems for such heat pumps, methods of managing refrigerant charge, and methods for heating and cooling a space and for heating water. Various embodiments deliver refrigerant gas to a heat exchanger that is not needed for transferring heat, drive liquid refrigerant out of that heat exchanger, isolate that heat exchanger against additional refrigerant flowing into it, and operate the heat pump while the heat exchanger is isolated. The heat exchanger can be isolated by closing an electronic expansion valve, actuating a refrigerant management valve, or both. Refrigerant charge can be controlled or adjusted by controlling how much liquid refrigerant is driven from the heat exchanger, by letting some refrigerant back into the heat exchanger, or both. Heat pumps can be operated in different modes of operation, and segments of refrigerant conduit can be interconnected with various components.
