Monitor the temperature at the cooling water outlet and further reduce power consumption through inverter control except during the peak summer daytime.
The flow rate sent to the cold water pump was adjusted by throttling the valve, but significant reductions in electrical power consumption were achieved by controlling it with an inverter. By monitoring the temperature at the cold water outlet with a temperature sensor, the pump motor's rotation speed can be controlled by the inverter, allowing for further energy savings except during the peak summer daytime. 【Features】 ○ Control Method: Pump motor rotation speed controlled by inverter using a temperature sensor ○ Target Equipment: Absorption chiller/heater Cold water pump (200V/55.0kW) For more details, please contact us or download the catalog.
