1. A control system for controlling liquid flow from a supply into a chilled beam, the control system comprising:
a supply input port;
a load return port;
a recirculation pump for pumping liquid from a pump input port to a pump output port, the pump input port connected to receive a first portion of liquid flowing from the load return port;
a junction configured to combine liquid flowing from the pump output port with liquid flowing from the supply input port;
a load input port configured to receive such combined liquid from the junction;
a supply return port connected to receive a remaining portion of the liquid flowing from the load return port;
a control valve to restrict flow of liquid between the supply input port and the supply return port;
a sensor; and
a control module to control the control valve based at least in part on a measurement from the sensor.
