A humidifier assembly for capturing moisture from the furnace and releasing the moisture into an area includes a furnace. A housing is coupled to the furnace. An inlet is coupled to the housing. The inlet is coupled to a drain line on the furnace. Condensation from the furnace is directed into the housing. A filter is removably coupled to the housing. The filter captures the condensation from the furnace and converts the condensation into an evaporate. The evaporate is released into the furnace. An outlet is coupled to the housing. An overflow line is coupled to the outlet. A reservoir is coupled to the overflow line to capture excess condensation. A secondary reservoir is fluidly coupled to the reservoir. A heating element in the secondary reservoir generates steam delivered to discharge ductwork of the furnace.

A machine core component, which is a universal part component for heater and fan manufacture, includes a core housing with a vertical structure having an air inlet at a lower end portion, an air outlet at an upper end portion, and an air duct formed between the air inlet and the air outlet; a driving motor and a wind wheel supported and received inside the core housing; and a heating element mounting window located at the air inlet for quick and easy installation of a heating element so that the machine core component can be used for fan or heater manufacture.

This concept is very new, and it will allow for safe and continuous operation of gas heating units when the induced draft fan no longer operates. This device will allow the HVAC service technician to continue to operate the gas heating unit until the proper replacement induced draft fan can be acquired and installed on the gas heating unit. This invention is a supplemental induced draft fan that will attach to the exhaust output side of a gas heating units inoperable induced draft fan to draft air through the heat exchanger and create a vacuum to the pressure switch at a rate to be regulated by a control switch to make the gas heating unit operate safely until the correct part is acquired and installed.

A fuel-fired furnace incorporates specially designed fuel/air mixing and combustion structures. The fuel/air mixing structure is of a mixing sound-attenuating design and comprises a venturi having a perforated sidewall portion and being surrounded by a noise-damping housing chamber communicating with the interior of the venturi via its sidewall perforations. During use of the mixing structure, air is flowed through the venturi in a swirling pattern while fuel is transversely injected internally against the swirling air. The combustion structure comprises a burner box housing into which the fuel/air mixture is flowed, combusted, and then discharged as hot combustion gas into and through the heat exchanger tubes. The fuel/air mixture entering the burner box housing initially passes through a non-uniformly perforated diffuser plate functioning to substantially alter in a predetermined manner the relative combustion gas flow rates through the heat exchanger tubes.

Disclosed is a high-temperature hot air blower capable of gathering energy and generating heat, including a machine housing (1) provided therein with a side wall (12) of a machine inner-side channel; an energy-gathering heat generator (13) is disposed on the side wall (12) of the machine housing inner-side channel and includes a heat generator transmission protective cover (14), a heat generator friction heat-generation body (15) and a heat generator heat-insulation isolation wall (16); the heat generator transmission protective cover (14) and the heat generator heat-insulation isolation wall (16) are respectively arranged on two sides of the heat generator friction heat-generation body (15), and are respectively in fit connection with the side surfaces of the heat generator friction heat-generation body (15); and the energy-gathering heat generator (13) is in fit connection with the side wall (12) of the machine housing inner-side channel via the heat generator heat-insulation isolation wall (16). The high-temperature hot air blower capable of gathering energy and generating heat disclosed herein can generate high-temperature hot air, and has the advantages of generating a large amount of hot air having a high hot air pressure, saving energy, having low noise, having multiple functions and a wide usage range, which can satisfy multiple usage demands for high-temperature hot air in production and living by people.

A gas furnace is provided. Embodiments of the present disclosure generally relate to a gas furnace operated such that the flame temperature is maximized by ensuring operation at or near stoichiometric conditions. Additional systems, devices, and methods are also disclosed.

An air conditioner may include a casing having an inner air flow space defined therein and an entrance defined in one of a first side plate or a second side plate, a heat exchanger and a fan disposed between an outdoor air inlet body and an air outlet body in an air flow direction of the casing, a heater module inserted through the entrance into the inner air flow space, a handle mounted on one side face among both side faces of the heater module, one side face of the both side faces being closer to the entrance than the other side face thereof, a pair of guide brackets installed in the casing to slidably guide the heater module, and a door module that opens and closes the entrance. The door module may be configured to contact the handle to press the handle in a direction away from the entrance.

A cabinet for a furnace filter is positioned beneath the base of a forced air furnace system, the cabinet being made up of a base plate, vertical side and end panels joined together to define a generally rectangular housing, one of the end panels having a door way and an upper door panel mounted in the door way and hinged along its lower edge with spring loaded hinges and pivotal side clip members between the door and sides of the door frame or side panels to securely retain the door in a closed position.
