  6. Ice storage air conditioning - Wikipedia

    en.wikipedia.org/wiki/Ice_storage_air_conditioning

    The capital cost is higher, as such a system requires somewhat larger chillers than those from a partial storage system, and a larger ice storage system. The air conditioning chillers' efficiency is measured by their coefficient of performance (COP). In theory, thermal storage systems could make chillers more efficient because heat is ...

  7. Chilled beam - Wikipedia

    en.wikipedia.org/wiki/Chilled_beam

    A chilled beam is a type of radiation/convection HVAC system designed to heat and cool large buildings through the use of water. [1] This method removes most of the zone sensible local heat gains and allows the flow rate of pre-conditioned air from the air handling unit to be reduced, lowering by 60% to 80% the ducted design airflow rate and the equipment capacity requirements.
