Abstract
A heat exchange system for controlling heat within an indoor space is provided. The system includes a heat exchanger located within the indoor space and a dual flow heat exchanger that is located in a space that is not temperature regulated by the system. The outdoor dual flow heat exchanger has flow through two different pluralities of parallel tubes that are interspersed between each other. The system includes a first expansion valve located within the indoor space to receive flow from one of the two sets of parallel tubes and cause flow to the indoor heat exchanger. The system includes a second expansion valve located in the non-temperature regulated space, wherein the second expansion valve receives flow from the second set of tubes and returns expanded lower pressure flow to the first set of tubes.
