Cooling System Arrangements A Series Arrangement System B Ined. the system with the lowest life cycle cost consisted of six electric centrifugal chillers with dual refrigeration cir cuits, that used 2 gpm (0.0358 ml j) of condenser water per ton of cooling, and was piped in a “series evaporator–series condenser” arrangement. as table 1 indicates, arranging the chiller evaporators in se. Download scientific diagram | cooling system arrangements: (a) series arrangement system, (b) parallel arrangement system, (c) individual cooling system. from publication: cooling system.
Cooling System Arrangements A Series Arrangement System B System power for vpf with series chillers. in systems with constant flow through the chillers' evaporators, designers often specify maximum acceptable pressure drops. the design flow pressure drop through a pair of chillers in series is likely to be much higher than what is considered acceptable in a parallel system. Configuring water cooled chiller plants in a series counterflow (scf) arrangement splits the lift between two machines to enhance the operating efficiency of the plant. in a scf configuration the chiller making the coldest chilled water also gets the coldest condenser water. now one machine will cool the water from 56 f° to 49 f° and the. The total lift produced by the scf system can be up to 20% lower than a conventional parallel system. lower lift means less work, and therefore a reduction in power consumption for a given cooling capacity. application considerations when a system is in a scf arrangement, appropriate field water piping design and proper controls algorithms are. 3, previously shown, is a common system set up for two chillers in a series counter flow arrangement for 1000 ton [3516 kw] cooling load. the industry standard for chiller conditions is set by ahri (air conditioning, heating & refrigeration institute), at which they certify performance on chillers. the industry.
