2. Free cooling - Wikipedia

   en.wikipedia.org/wiki/Free_cooling

   Integral chillers are ideal for sites which have limited space and can offer high energy efficiency levels. These units feature high quality components including scroll and screw compressors, axial fans, and three-way modulating valves. [citation needed] The other options is an independent free cooler that has a greater capacity for heat ...

3. Chiller - Wikipedia

   en.wikipedia.org/wiki/Chiller

   A liquid (glycol based) chiller with an air cooled condenser on the rooftop of a medium size commercial building. In air conditioning systems, chilled coolant, usually chilled water mixed with ethylene glycol, from a chiller in an air conditioning or cooling plant is typically distributed to heat exchangers, or coils, in air handlers or other types of terminal devices which cool the air in ...

4. 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.

5. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   The COP of absorption chillers can be improved by adding a second or third stage. Double and triple effect chillers are significantly more efficient than single effect chillers, and can surpass a COP of 1. They require higher pressure and higher temperature steam, but this is still a relatively small 10 pounds of steam per hour per ton of cooling.

6. Ice storage air conditioning - Wikipedia

   en.wikipedia.org/wiki/Ice_storage_air_conditioning

   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 discharged into colder nighttime air rather than warmer daytime air. In practice, heat loss overpowers this advantage, since it melts the ice.

7. Chiller boiler system - Wikipedia

   en.wikipedia.org/wiki/Chiller_boiler_system

   A chiller boiler system is a hydronic system. It uses water instead of air to heat and cool a structure. A properly designed hydronic system is usually more efficient than a standard forced air system. [1] Chiller boiler systems use radiant heating and cooling or fan coil systems to condition a home or business. This allows for multiple zones ...
