Air conditioning equipment consume around 70% of total building energy and
constitutes 70% of the peak electric demand. By shifting that load from individual
houses to a central plant, the housing electric load is reduced substantially and
along with it the number of electric substations and length and sizes of electric
District cooling requires far less electric power than multiple plant rooms or
ducted splits. Furthermore the plant room can house the electric substation,
enormously reducing the electric works.
Electric demand and peak shaving are easily controlled when district cooling is
applied. This especially important in the case of on-site continuous or standby
Gas engine chiller can be used for standby or peak shaving operation in parallel
with electric chillers.
