An electric fireplace (1210) includes a fireplace housing (412) and a heater assembly (1226) that is configured to generate heated air. The heater assembly (1226) is configured to be installed substantially within the fireplace housing (412). In various embodiments, the heater assembly (1226) includes a heater body (1245), and a grill cover (1248) that is couplable to the heater body (1245). The grill cover (1248) includes a cover body (1295) that is couplable to the heater body (1245), and at least one extender (1296) that is configured to be positioned substantially adjacent to the cover body (1295). The cover body (1295) has a first cover length. The cover body (1295) and the at least one extender (1296) cooperate to have a second cover length that is greater than the first cover length. The second cover length is substantially equal to a dimension of the fireplace housing (412).

A firebox is provided for use in a gas fireplace, the firebox comprising: a back which includes at least one combustion fan aperture, an upper end and a lower end and a length therebetween, a pair of sides, each side including an upper end, a lower end, a first riser which has an inner section and an outer section, the inner section attached to the back, a first flange, which is parallel to the back and extends outward from the back, and a second riser, wherein the outer section of the first riser, the first flange and the second riser extend above the upper end of the back and below the lower end of the back; a top which is attached to the inner section of the first risers and to the back at the upper end; and a base which is attached to the inner section of the first risers and to the back above the combustion fan aperture, to define an opening. The fireplace is also provided.

An apparatus, system and method for dispensing underfill to components on a printed circuit board. The apparatus, system and method may include an underfill chamber having an input through which the printed circuit board is received; at least one dispensing robot capable of dispensing the underfill to the components; a lower heater suitable to substantially evenly heat at least half of or the entirety of an underside of the printed circuit board once the printed circuit board is within the underfill chamber; and an overhead heater capable of heating up to half of a topside of the printed circuit board once the printed circuit board is within the underfill chamber.

The present invention provides for a mobile heating apparatus for heating an enclosed space to a temperature sufficient to kill bed bugs. The mobile heating apparatus has a recirculation chamber having a fresh air inlet configured to receive fresh air from a fresh air area and a recirculation air inlet configured to receive recirculation air from a heated air area. The fresh air area is located outside of the area to be heated. The heated air area is located within the area to be heated. The apparatus also has an air mixture/circulation apparatus configured to mix the fresh air and the recirculation air and an air heating chamber having a heat exchanger. A mixed air inlet is in communication with the air mixture/circulation apparatus. A heated air outlet is configured to route the heated air into the heated air area. A heating apparatus is configured to provide heated combustion flow to the heat exchanger. The present invention also provides for a related method.

A split bay forced draft air-cooled heat exchanger includes first and second bay sub-assemblies. Each sub-assembly includes a tube bundle, a plenum half positioned under the tube bundle and base beams supporting the tube bundle and the plenum half. Also included is a fan assembly having a fan, a fan motor and a drive assembly and a machinery mount upon which the fan assembly is mounted. The machinery mount is attached to base beams of the first bay sub-assembly and is configured to removably attach to base beams of the second sub-assembly with the fan configured to force air into a plenum made up of the plenum halves and across the tube bundles.

In alternative embodiments, provided are products of manufacture, including automobiles and buildings, and multiplexed systems such as ventilation systems, for treating, preventing, ameliorating, slowing the progress of, decreasing the severity of or preventing a microbial infection, such as bacterial and viral infections, including the common respiratory viruses such as infuenza virus, respiratory syncytial virus, parainfluenza virus, adenovirus, rhinovirus, human metapneumovirus, hantaviruses, enterovirus, coronavirus (such as a SARS, MERS or COV1D-19 infection), or an infection caused by a virus in the subfamily Orthocoronavirinae, or a virus in the family Coronaviridae, or a virus in the order Nidovirales.

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.

Systems and methods for controlling conditions in an enclosed space, such as a data center, or for providing cooling to a device, can include using a Liquid-to-Air Membrane Energy Exchanger (LAMEE) as an evaporative cooler. The LAMEE or exchanger can cool water to the outdoor air wet bulb temperature in a cooling system disposed outside of the enclosed space or device. The reduced-temperature water can be delivered to the enclosed space or device or can cool a coolant that is delivered to the enclosed space or device. The air in the enclosed space, or one or more components in the enclosed space, can be cooled by delivering the reduced-temperature water or coolant to the enclosed space, rather than moving the supply air from the enclosed space to the cooling system. In an example, the cooling system can include one or more cooling coils, upstream or downstream of the LAMEE.

Embodiments relate generally to a heated towel rack that includes at least one lateral support, at least one forced air heating unit in fluid communication with a channel within a lateral support, and at least one cross bar coupled to the at least one lateral support. The at least one cross bar including at least one vent that traverses into a conduit within the cross bar. The channel is in fluid communication with the at least one vent by way of the conduit.
