The present labor sufficiency aims to select the best and optimal components for the automation of the chilled water pumps, fans in the cooling tower and alternation of these in the Wiese building in 2020. The chilled water plant is made up of 2 Carrier brand Chillers with 375 tons of cooling capacity, 3 primary pumps of 20HP, 2 secondary pumps of 75HP, 3 condensation pumps of 40HP and 2 cooling towers of 20HP. The alternation will take into account the state of the pump or fan for its correct operation to avoid the chiller stopping due to lack of water flow or high temperature in the condensation circuit. Additionally, mantenance staff will be able to change the start and stop time and view which equipment is in operation in a SCADA system. For the analysis of results, the start-up tests were taken into account, which consists of changing the states of the pumps in the field and tags in the PC system; according to these changes, the system should behave following the controller programming. Finally, it is concluded that the best components for starting the pumps are soft starters and frequency converters, the latter only if pressure or temperature control is desired. To monitor and control the alternation of the pump, an S7-1200 PLC connected to a PC system running the WinCC RT Professional program was chosen.
