Abrégé

Chilled-beam zone pump modules for controlling zones of a chilled-beam heating and air conditioning system, multiple-zone chilled beam air conditioning systems for cooling multiple-zone spaces, and methods of controlling chilled beams in multi-zone air conditioning systems. Embodiments include a pump serving each zone that both recirculates water within the module and chilled beam and circulates water in and out of a chilled or warm water distribution system through valves to control temperature. Different embodiments provide heating as well as cooling, use check valves to reduce the number of control valves required, adjust the temperature of the beam to avoid condensation, change pump speed to save energy or increase capacity, can be used in two- or four-pipe systems, allow for lower installation cost, provide better performance or control, improve reliability, overcome barriers to the use of chilled beams, or a combination thereof.
