Abstract
Air conditioning systems for cooling multiple-zone spaces, each zone having a thermostat, where each of multiple pump modules delivers chilled water to chilled beams in a plurality of zones and a chilled-water distribution system circulates chilled water through a chilled-water distribution loop to the multiple pump modules. Current dew points are determined in zones that call for cooling, and temperature of chilled water delivered to the chilled beams is maintained for each pump module at least a predetermined temperature differential above the highest dew point within the zones served by that pump module. Each zone has a zone control valve to shut off flow to that zone. Serving a plurality of zones from each pump module reduces how many pump modules are required. Zones served by one pump module may be selected to have similar thermal loads. Pump modules may supply hot water when heat is needed instead of cooling.
