Waste heat recovery systems and methods for a livestock barn

A thermal exchange system for a livestock barn, said system comprising:

• a main cabinet comprising:
• a fresh air flow inlet fluidly connectable to an ambient outdoor environment;
• a fresh air flow outlet fluidly connectable to an interior of a livestock barn;
• a waste air flow inlet fluidly connectable to the interior of a livestock barn;
• a waste air flow outlet fluidly connectable to the ambient outdoor environment;
• at least one access opening;
• and
• at least one access panel structured and operable to removably cover the at least on access opening;
• at least one tube bundle cell structured and operable to be removably disposed within the main cabinet via the at least one access opening, each tube bundle cell comprising:
• a plurality of tubes arranged substantially parallel with each other and having space between adjacent tubes, each tube having an exterior surface and an interior lumen extending therethrough;
• and
• a first end panel and a second end panel, each of the first and second end panel having a plurality of bell-mouthed openings extending therethrough, each bell-mouth opening comprises a curved funnel-shaped head portion and a tubular neck portion extending from the head portion, wherein the plurality of tubes are each connected at a first end to the neck portion of a respective one of the bell-mouth openings in the first end panel, and connected at an opposing second end the neck portion of a respective one of the bell-mouth openings in the second end panel;
• at least one waste air fan structured and operable to generate a waste air flow that draws waste air from inside the livestock barn into the waste air inlet, passes the waste air around the exterior surfaces of the tubes, and exhausts the waste out the waste air outlet and into the ambient outdoor environment;
• and
• at least one fresh air fan structured and operable to generate a fresh air flow that draws fresh air from the ambient outdoor environment into the fresh air inlet, passes the fresh air through the interior lumens of the tubes wherein the fresh air flow thermally exchanges heat with waste air flow to change the temperature of the fresh air flow, and forces the changed temperature fresh air out the fresh air outlet and into the livestock barn.
