Abstract: An air conditioner unit includes a variable speed compressor for circulating refrigerant through an outdoor heat exchanger and an indoor heat exchanger, an indoor fan, and an outdoor fan. A controller obtains an indoor temperature using an indoor temperature sensor and operates the variable speed compressor, the indoor fan, and the outdoor fan at a first capacity level to adjust the indoor temperature toward a target temperature. The controller determines that a rate of change of the indoor temperature is below a predetermined rate threshold and operates the variable speed compressor, the indoor fan, and the outdoor fan at a second capacity level.

Abstract: A method of operating an air-treatment appliance, as provided herein, may include directing a fluid-motivating unit (FMU) to motivate a fluid through the air-treatment appliance based on a condition setpoint. The method may also include receiving an ambient condition signal. The method may further include measuring a total active time of the FMU over a predetermined time period and estimating a power consumption based on the total active time of the FMU. The method may still further include determining a diagnostic state of the air-treatment appliance based on the ambient condition signal and the estimated power consumption. The method may include transmitting a state signal to a user interface according to the determined diagnostic state.

Abstract: A gas feed tube assembly for a gas fueled water heater and a water heater including such assembly. A pair of gas tubes are connected with one tube received into the other and secured between a pair of complementary fasteners position along a wall or door the water heater. The gas feed tube assembly can be more readily manufactured, facilitates installation of the water heater, and helps minimize gas leaks.

Abstract: A system for monitoring temperature in the combustion chamber of a gas fueled water heater using a thermoelectric device placed near the gas burner. Based on the measured temperature, the water heater can determine whether abnormal operation is occurring that would require closing the flow of gaseous fuel to e.g., the main burner, pilot burner, or both.

Abstract: A gas water heater that includes a sheathed thermistor placed into the combustion chamber near a gas burner to provide for more accurate measurements of the temperature therein.

Abstract: A water heater defines a vertical direction and includes a tank for holding water. The water heater further includes a shroud positioned over the tank along the vertical direction. The shroud defines a chamber over the tank, and includes a partition wall that divides the chamber into first and second chamber portions. The water heater includes an evaporator disposed within the first chamber portion, and a compressor disposed within the second chamber portion. The partition wall is positioned between the evaporator and compressor within the chamber of the shroud. Further, the shroud defines a vent extending through the shroud to the chamber of the shroud. In one embodiment, the vent is contiguous with the first chamber portion.

Abstract: Air conditioner units, bulkhead assemblies, and methods for operating air conditioner units are provided. A bulkhead assembly includes a bulkhead which includes a first sidewall, a second sidewall, and a rear wall extending laterally between the first sidewall and the second sidewall. The rear wall includes an indoor facing surface and an opposing outdoor facing surface. The bulkhead assembly further includes a vent aperture defined in the rear wall, and a vent door movable between an open position and a closed position, wherein in the open position the vent door permits air flow through the vent aperture and in the closed position the vent door inhibits air flow through the vent aperture. The bulkhead assembly further includes a drive assembly connected to the vent door and operable to selectively move the vent door between the open position and the closed position.

Abstract: Air conditioner units are provided. A unit includes an outdoor heat exchanger, an indoor heat exchanger, and a compressor. The unit further includes a bulkhead disposed between the outdoor heat exchanger and the indoor heat exchanger. The unit further includes a vent aperture defined in the bulkhead. The unit further includes a dehumidification system disposed at least partially within the outdoor portion, the dehumidification system including an evaporator configured for removing heat from outdoor air flowing therethrough, a condenser configured for adding heat to outdoor air flowing therethrough, and an auxiliary compressor in fluid communication with the evaporator and the condenser.

Abstract: Multi-compartmentalized ink cartridges for ink jet printers and improved methods for making the ink cartridges. The multi-compartmentalized ink cartridge includes a molded, open-topped body having an interior cavity and a printhead surface area opposite the interior cavity. A divider wall is integrally molded with the molded body structure and disposed in the interior cavity to provide at least three segregated ink chambers. The divider wall includes a first wall section and a second wall section attached substantially perpendicular to the first wall section. At least first, second, third molded ink flow paths connect each of the at least three segregated ink chambers with the printhead surface area. The second and third ink flow paths are oriented relative to their corresponding ink chambers for molding with a mold insert tool so that the cartridge body does not require a separately attached member to close mold insert tool insertion areas in the body.
