Abstract: The problem of controlling the temperature of the different units in a process tool system which have to be cooled or heated using thermal transfer fluid at selected setpoints and flow rates is resolved by a system having multiple modular units each with some operative and form factor commonality but at least dual functional capability. The modular units each have separate recirculation loops for thermal transfer fluid but cool the fluid using refrigeration cycles or facilities water supplies or heat the fluid using compressed hot gases or electrical energy. By employing operative units which can be internally varied to provide different thermal capacities within form factor constraints, the system enables concurrent temperature control needs of a number of different units to be met with an energy efficient, low footprint, highly adaptable system.

Abstract: A damper assembly for use in conjunction with a conventional air conditioning system. The damper assembly includes a flexible damper which has a configuration and dimension to cover the grillwork of the air conditioning system. The damper further includes a centrally located magnet which allows it to be magnetically coupled to the grillwork.

When the air conditioning system is in operation. the periphery of the damper is caused to blow upwardly by way of air passing through the blower assembly. When this occurs, the magnet functions to keep the damper secured to the grillwork. In this manner, the damper does not preclude air flow from the blower assembly during normal air conditioning operation.
