Abstract:
1. A method of evaluating performance of a chiller system, comprising the following steps: (1) determining a number of a plurality of chillers and a number of a plurality of cooling towers, and then determining a plurality of allocating assemblies having different numbers of activated chillers and activated cooling towers, according to the numbers of the chillers and the cooling towers; (2) determining the lowest outlet temperature of cooling water of the cooling towers in each allocating assembly, such that each of the allocating assemblies and the corresponding lowest outlet temperature of the cooling water form a plurality of system allocating combinations; (3) selecting one of the system allocating combinations, and determining an inlet temperature of the cooling water of each chiller; (4) determining a total power consumption of the activated chillers in the system allocating combination; (5) determining a total power consumption of the activated cooling towers in the system allocating combination; (6) determining a total power consumption for pumping cooling water and chilled water in the system allocating combination, and then determining a total system power consumption of the system allocating combination by adding the total power consumption of the chillers, the total power consumption of the cooling towers, and the total power consumption of the pumping; and (7) selecting another system allocating combination, and determining a total system power consumption of the system allocating combination, so as to determine the total system power consumptions of all the system allocating combinations.
