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： 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： A control procedure operates an expansion valve (120) of an air conditioning system. The control procedure utilizes a first control procedure to bring a calculated su perheat value within a range of a target superheat value, and a second control procedure to cause the calculated superheat value to match the target superheat value. Both the first and second control procedures preferably use Proportional, Integral, Derivative control algorithms.

摘要： Methods of controlling air conditioning and HVAC units using a thermostat for a discrete- speed unit that include changing speed based on how long the unit operates at a particular speed. Speed may be increased if a unit operates for longer than a predetermined time at a particular speed, and speed may be reduced if the unit operated for less than a specific amount of time during the prior run. In different embodiments, single-stage thermostats may control units that operate at three speeds, and two-stage thermostats may control units that operate at five speeds. In addition, in some embodiments, outdoor coil temperature may be measured and considered in determining speed. Further, in some embodiments, maintaining continuous operation at a boost speed may be avoided. Energy savings and noise reduction may result.
摘要翻译：使用用于离散速度单元的恒温器控制空调和HVAC单元的方法，包括基于单元以特定速度运行多长时间来改变速度。如果单元以特定速度操作长于预定时间，则可以增加速度，并且如果在先前运行期间单元操作少于特定量的时间，则速度可能会降低。在不同的实施例中，单级恒温器可以控制以三个速度操作的单元，并且两级恒温器可以控制以五个速度操作的单元。此外，在一些实施例中，可以在确定速度时测量和考虑室外线圈温度。此外，在一些实施例中，可以避免以升高速度保持连续操作。可能导致节能降噪。
