ABSTRACT:
A method and apparatus for utilizing the cool outdoor air or other cooling sources for cooling a volume are disclosed. The system comprises at least two coils suitable fluid pipe line, fluid and a circulator pump. In the preferred embodiment, indoor and outdoor coils and the circulator are connected by circulation piping containing a heat transfer fluid, the fluid being isolated from ambient air. In winter the circulator pump is activated and warm fluid flows through the outdoor coil, causing the fluid in the coil to release heat, the coil fluid flows through the indoor coil, causing the fluid in the indoor coil to absorb heat. Such a system can be used to cool a volume when the ambient, outdoor air is cooler than the air within the volume.
