Abstract
A heating/cooling system modulates the temperature of water flowing through a hydronic emitter by mixing water flows through a mixing valve. The mixing valve has an inlet connect to a water flow pipe, an inlet connected to a water return pipe, and an outlet connected to the hydronic emitter. Water flows through the inlets are configured to obtain a desired mixed water flow at a targeted temperature through the outlet. A controller receives temperature information from a thermometer and then determines the targeted temperature of the outlet. The controller then determines an inlet ratio and configures the mixing valve based on the ratio. The heating/cooling system may support one or more heating/cooling zones and may operate either in a heating or a cooling mode.
