摘要： An improved power vent and associated control system for a heating apparatus such as a furnace. The invention utilizes a vent blower and a flow control orifice device permitting the use of a single size air moving device and motor with different size furnaces. The control is arranged to discontinue delivery of fuel to the furnace in the event of a blockage of the furnace flue or a failure of the air moving structure. In one form of the invention, a pressure condition is sensed downstream of the air moving structure to detect the failure conditions. In another form of the invention, the control utilizes structure to sense the speed of the air moving device. The invention comprehends the use of a motor for driving the air moving device which varies in speed substantially between the unloaded and loaded conditions. The air moving device preferably unloads under high discharge pressure conditions, such as by a blocked flue. In a preferred form of the invention, a closure closes the orifice during periods when the vent blower is not operating. The closure is responsive to fluid movement through the orifice to move automatically to an open condition.

摘要： A heat pipe heat transfer structure for use in a furnace wherein individual heat pipes are arranged in a series for successive heat transfer association with the hot products of combustion of the furnace. The heat transfer enclosure defines successively a combustion chamber portion, an acoustic decoupling portion, and an input heat transfer chamber portion. The heat transfer chamber portion, in turn, is divided into first and second portions. The first portion of the input heat transfer chamber portion, in the illustrated embodiment, decreases in cross sectional area in a direction away from the burner. The final portion of the input heat transfer chamber portion, in the illustrated embodiment, has a constant cross sectional area. The heat pipes are arranged in a folded series row, with the direction of the products of combustion being reversed in entering the first portion from the combustion chamber and in passing from the first portion to the second portion before being discharged to the vent pipe of the furnace. The construction provides improved uniform loading of the heat pipes and acoustic decoupling of the burner from the input heat transfer chamber portion.

摘要： A fluid flow device having a biased closure structure for selectively closing an opening in a flow conducting structure. The closure includes a pair of closure members pivoted relative to a transverse axis of the opening and biased to the closed position by a spring which is maintained spaced from the closure members in the closed position thereof. The spring has a midportion which is brought into engagement with the closure members as an incident of the movement thereof to and beyond a preselected position intermediate the closed and fully opened positions of the closure members. The spring acts to resiliently bias the closure members toward the closed position as result of the spring tension between the closed position and the intermediate position and the abutment of the midportion of the spring with the closure members at and beyond the intermediate position permits the closure members to be swung toward the fully open position with a decreased force.

摘要： A control system for a central air conditioner. The air conditioner includes an outdoor condensing unit including a refrigerant compressor, an indoor evaporator unit, an indoor thermostat responsive to the indoor temperature for controlling the air conditioner, and a control system for protecting the air conditioner and indicating to the user certain malfunctions in the air conditioner should they occur. The malfunction indication may be by means of signal lights and a manually operable reset control is provided permitting the user to reset the control system. The malfunction indicator and reset control are disposed adjacent the thermostat for facilitated determination of the system operating condition. The control system includes an improved control portion for starting of the compressor motor which is arranged to prevent operation of the system in the event of a low power supply voltage condition. The control system provides a minimum "Off" reset time before permitting the air conditioner to automatically attempt to restart regardless of the condition causing stopping of the air conditioner. The control system further includes a current sensing control which determines the compressor motor current a preselected time after the closing of the compressor motor switch and is arranged to discontinue operation of the compressor motor in the event the current is above a preselected high value. Clock pulses are used to facilitate operation of the current sensing control. Improved accuracy in the timing of the control system is obtained by means of coordinated use of clock pulses and R-C time delays.

摘要： The present invention is a diagnosis and testing system for a temperature control system which includes a communication bus, a control processor, and a service thermostat. The communication bus is coupled to substantially all of the components of the system. The control processor initiates communication between components by sending a bus address over the bus. The control processor includes an address decoder for recognizing various bus address signals, including a normal thermostat bus address and a service thermostat bus address. The service thermostat has a switch, a processor, and a bus interface unit. The switch selects the operating mode of the service thermostat, e.g. either normal or service modes. The bus interface unit communicates over the bus for the service thermostat processor. The service thermostat processor operates the service thermostat and is adapted to communicate over the bus using a bus address according to the operating mode which is determined by the switch.

摘要： An improved fin configuration is provided for use in central air conditioning unit heat exchangers in which heat transfer takes place between a first fluid, typically a refrigerant, flowing inside a nested plurality of tubes and a second fluid, typically air, flowing between the tubes and through a plurality of heat conducting fins attached to and arrayed between the tubes. Lanced pairs of streamwise adjacent bridge-like formations, one out each side of a generally corrugated fin surface, provide numerous leading edges to generate a plurality of reforming velocity and heat transfer boundary layers which leads to an increase in flow turbulence for enhanced heat transfer between the fins and the second fluid. By strategic location of a pair of such formations between tubes, with the upstream one of the pair at a positive angle of attack to the flow, air flow is directed through the fin to mix with flow on the other side of the fin and hence the heat transfer rate is improved. The provision of a shallow conical annular fin region around each collar attaching a fin to a tube, preferably with a 6.degree. inclination of the conical surface to a plane orthogonal to the collar axis, provides additional enhancement to the heat transfer between the fin and the second fluid.
