A pump liner is used to direct a laminar flow of purge gas across a workpiece to remove contaminants or species outgassed or otherwise produced by the workpiece during processing. The pump liner can take the form of a ring having a plurality of injection ports, such as slits of a variety of shapes and/or sizes, opposite a plurality of receiving ports in order to provide the laminar flow. The flow of purge gas is sufficient to carry a contaminant or outgassed species from the processing chamber in order to prevent the collection of the contaminants on components of the chamber. The pump liner can be heated, via conduction and irradiation from a radiation source, for example, in order to prevent the condensation of species on the liner. The pump liner also can be anodized or otherwise processed in order to increase the emissivity of the liner.

Embodiments of the invention describe thermostats that use model predictive controls and related methods. A method of controlling a thermostat using a model predictive control may involve determining a parameterized model. The parameterized model may be used to predicted ambient temperature values for an enclosure. A set of radiant heating system control strategies may be selected for evaluation to determine an optimal control strategy from the set of control strategies. To determine the optimal control strategy, a predictive algorithm may be executed, in which each control strategy is applied to the parameterized model to predict an ambient temperature trajectory and each ambient temperature trajectory is processed in view of a predetermined assessment function. Processing the ambient temperature trajectory in this manner may involve minimizing a cost value associated with the ambient temperature trajectory. The radiant heating system may subsequently be controlled according to the selected optimal control strategy.

A panel for radiant heating and cooling includes a moisture impermeable shell with protrusions extended from a base. Channels between adjacent protrusions frictionally retain a thermal control component such as flexible tubing or an electrical heating element. The protrusions define chambers open at the bottom of the shell. An anchor in each chamber is secured to the top wall and extends downwardly beyond the base. A thermally conductive film is applied to the top surface of the shell. An insulative layer extends downwardly from inside the shell and beyond the base, surrounding the anchors while leaving bottom surfaces of the anchors exposed. The anchors are secured to a floor or substrate by an adhesive to integrally mount the panel. The anchors can receive and frictionally retain axially driven fasteners such as nails and staples, facilitating the attachment of a flooring overlayer integrally with respect to the substrate through the panel.

The present invention provides a safer all-around radiation heating assembly than similar traditional heaters. As typical with traditional heaters, a shroud is used to surroundably cover a portable liquid propane tank. To replace the portable liquid propane tank, the shroud must be continuously raised to a predetermined height while a service person accesses the propane tank. There is a danger that if and when the shroud drops, a spark could be created resulting in igniting highly flammable escaped propane gas. The present invention overcomes dangers associated with the traditional heaters by eliminating the spark creation danger and by introducing a ventilation system to allow any leaked propane gas to escape away from the heater.
