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