In an air cooling mode of cooling air as a fluid to be heat-exchanged, a refrigeration cycle device is provided to perform switching to a refrigerant circuit in which a high-pressure refrigerant exchanging heat with outside air in an exterior heat exchanger and dissipating heat therefrom flows into an accumulator serving as a gas-liquid separator. In an air heating mode of heating the air, the refrigeration cycle device also performs switching to another refrigerant circuit that allows a low-pressure refrigerant decompressed by a first expansion valve to flow into the accumulator. Thus, even in any operation mode, a difference between a refrigerant temperature in the accumulator and the outside air temperature is reduced to thereby suppress the degradation of performance of the refrigeration cycle device due to the unnecessary transfer of heat between the refrigerant in the accumulator and the outside air.

A furnace for combusting wood comprises a firebox floor in a primary burn chamber of the furnace, where the wood is received for generating a gas therefrom, that is defined by a thermally conductive body of refractory material. The body of refractory material defines an upper support surface arranged to support the wood above or over the same. The body of refractory material also defines, beneath the upper support surface, a duct as part of a secondary burn chamber of the furnace which is arranged (i) to be communicated with the primary burn chamber of the furnace to receive the gas generated by heating of the wood therein and carrying combustible products, and (ii) to convey the gas in a manner supporting combustion of the combustible products carried thereby.

Evaporator system used for the production of maple syrup. The evaporator system includes at least one receptacle, a combustion chamber, an evacuation port and an air supply system. The evaporator system also includes a door assembly being configured for removably mounting onto a corresponding support frame of the evaporator system, and being operable between an opened configuration for allowing access to the combustion chamber and to be able to selectively feed biomass into the combustion chamber via the inlet thereof, and a closed configuration for preventing access to and closing off the inlet of the combustion chamber, the door assembly being provided with at least one aeration passage extending between an outer portion of the door assembly and an inner portion therefor, for providing a supply of secondary air to the combustion chamber via said at least one aeration passage of the door assembly when operated in the closed configuration.

A fire pit comprising a body having a side wall structure. The body further comprises a base plate located adjacent a lower end portion of the side wall structure, and an opening defined by a perimeter of an upper end portion of the side wall structure. Together, the side wall structure and the base plate form a fire pit chamber. The lower end portion of the side walls and the base plate form a collection sump for collecting and retaining ash that is generated during use. The lower portion of two opposite side walls and and the base plate are tapered downwards towards the center of the base plate to facilitate collection of ash.

A biomass burner includes a hopper, a ventilating chamber, a U-shaped fire box, a feeding cylinder including an output end, an auger, a feeding motor including a driving wheel, an ignition device, an ignition motor, a ventilation plate, a first poking device, a second poking device, a first poking motor configured to drive the first poking device, a second poking motor configured to drive the second poking device, a first fixed plate, and a second fixed plate. The hopper is disposed below the feeding cylinder. The feeding cylinder is disposed through the ventilating chamber and the output end of the feeding cylinder extends into the U-shaped fire box. The auger is disposed in the feeding cylinder and is driven by the feeding motor; one end of the auger is provided with a driven gear, and the driven gear is meshed with the driving wheel of the feeding motor.

Exemplary embodiments of a system and method for bimodal air control in a kettle-style grill are configured to be detachably mounted to the exterior of a kettle-styled grill such as, but not limited to, a Weber® charcoal grill. When mounted to the kettle-styled grill, a plenum-like component directs air flows to the interior of the grill's kettle via the kettle's lower body damper holes. A manually adjustable intake damper in the plenum component allows, restricts, or prevents a drawn ambient air flow into the plenum component. Separately, a forced air flow generated by a fan may also be provided into the plenum component. Adjustment of the intake damper may also adjust damper blades inside the grill's kettle. Ash that falls out of the kettle's damper holes falls through the plenum component and is captured in an ash receptacle that is removably mounted to the plenum component.

A system for a forced air flow into a kamado-style cooker comprises a control unit and an adapter defining an airflow duct with an entrance aperture and an exit aperture. The adapter is configured to removably mount over a lower damper port in a kamado-style cooker such that the exit aperture is aligned with the lower damper port. The control unit comprises an electric fan, one or more sensor input ports, and an airflow exit duct. The control unit is configured to separably mate with the adapter such that the airflow exit duct of the control unit is received by the entrance aperture of the adapter. Advantageously, a forced air flow generated by the electric fan, in response to a temperature signal input, passes out of the control unit, through the adapter, and into a body portion of the kamado-style cooker to encourage, facilitate and manage combustion within the cooker.

The present invention relates to a foldable containment bag for charcoal, designed to seamlessly remove used or spent charcoal and ashes directly from a grill. The bag can be unfolded in a planar sheet to insert into a grill. The sheet is flexible and conforms to the shape of the inside surface of the grill. The sheet includes a top surface, a bottom surface and a mesh of flexible aluminum wiring disposed within the top surface and the bottom surface. During use, charcoal is placed on the top surface of the sheet, and after use of the grill, the sheet can be folded to form a bag that firmly secures the used charcoal and associated ashes for transportation and disposal. The bag can have folding lines to fold and unfold for use.
