Abstract
A hydronic economizer module is configured for use in a chiller system that has a vapor compression cycle. The hydronic economizer module includes a heat exchanger assembly located within a housing having at least one heat exchanger coil, a fan assembly having at least one fan generally aligned with at least one heat exchanger coil, and at least one valve is movable between a plurality of positions to control a flow of fluid into the heat exchanger assembly. When the at least one valve is in a first position, the economizer module is arranged in parallel with a flat plate heat exchanger. When the at least one valve is in a second position, the economizer module is arranged in series with the flat plate heat exchanger. The flat plate heat exchanger includes at least one fluid port for communicating with a component of the vapor compression cycle.
