For a human-powered version, see yakhchal.. When the ambient air temperature drops to a set temperature, a modulating valve allows all or part of the chilled water to by-pass an existing chiller and run through the free cooling system, which uses less power and uses the lower ambient air temperature to cool the water in the system.
Chilled water cooling is not very different from typical residential air conditioning where water is pumped from the chiller to the air handler unit to cool the air. Regardless of who provides it, the chilled water (between 3 and 6 °C (37 and 43 °F)) is pumped through an air handler , which captures the heat from the air, then disperses the ...
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [ 1 ] [ 2 ] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.
Capital expenditures are minimized because the chillers can be just 40 - 50% of the size needed for a conventional design. Ice storage sufficient to store half a day's rejected heat is usually adequate. A full storage system minimizes the cost of energy to run that system by entirely shutting off the chillers during peak load hours.
District cooling is the cooling equivalent of district heating. Working on broadly similar principles to district heating, district cooling delivers chilled water to buildings like offices and factories. In winter, the source for cooling can often be seawater, so it is a cheaper resource than electricity to run compressors for cooling.
