Abstract: Exemplary embodiments are directed to a gas switching device including a body and a gas selector mechanism. The body includes an inlet and an outlet. The gas selector mechanism includes a first orifice in fluid communication with the inlet and a second orifice in fluid communication with the inlet. The gas selector mechanism includes a valve arm and a selector element. The selector element is configured to actuate the valve arm between a closed position and an open position. In the closed position, the selector element actuates the valve arm to close the second orifice for passage of a first type of gas through the first orifice. In the open position, the selector element actuates the valve arm to open the second orifice for passage of a second type of gas through both the first orifice and the second orifice.

Abstract: In a first aspect of the present invention, a header for a heat exchanger is disclosed that has an inflow side, an outflow side, a bypass port therebetween, and a pressure-sensitive flapper valve proximal the bypass port. As pressure increases at the inflow side of the header, the flapper valve opens proportionally, and, as pressure decreases at the inflow side, the flapper valve closes proportionally. In a second aspect of the present invention, a tube-in-tube heat exchanger is disclosed that includes a helical tube-in-tube assembly adapted for flow therethrough of a plurality of fluids for heat transfer therebetween. In a third aspect of the present invention, a heat system is provided to include an embodiment of the header and an embodiment of the tube-in-tube heat exchanger, so as to provide a bypass of the tube-in-tube heat exchanger under a pressure condition.
