2070 Cost Saving Power Management System
Realizing 20% cooling and chilled water flow control!
System for 70% reduced electricity cost!
Development of refrigeration system for controllable precise flow of cooling and chilled water
■ Development of refrigeration system for controllable precise flow of cooling and chilled water.■ Maintenance of the maximum temperature difference in the temperature difference between the inlet and outlet of the cooling and chilled water under partial load.
■ Operation on 100% load, control operation with partial load after stabilizing.
Electricity cost of cooling and chilled water pump have reduced by 70% than previous year.
Researching for 1.6 year, selected as a demonstration complex (Pan-gyo Startup Campus), the electricity cost has reduced 70% than previous year by cooling and chilled water pump control technology of World Energy.Upgrade its safety by installing the pipe assembly for low flow detection as self-development.
Protection device for water outage to detect cooling and chilled water flow under low condition of 20% cooling and chilled water flow.Consistent reduced operating costs through initial low installation cost (inverter).
Initial installation cost can be recovered within a year or 2 (It may be partially different depending on the site condition.)Comparison table of electricity cost savings and payback period by World Energy refrigeration capacity (running time per year: 1,075 hours).
Electricity cost savings system, joint R&D with Korea District Heating Corporation
Period: May 14, 2018 ~ October 13, 2019 (Total 1.6 year)
Place: Pan-gyo Startup Campus
Model: 2ABH210 (193usRT) x 2 units
Being stable with low speed by the pump rotation speed control under cooling load fluctuation, and energy is saved by lower pump power and power consumption
The lowest 20% flow detection test, World Energy factory experiment completed
Period: January 2, 2019 ~ February 28, 2019
Place: Performance Test Center in World Energy
Change of flow rate and pump power by the inverter control of the cooling and chilled water pump.
When the load is changed, maintain the normal condition of the pump rotation speed, the surface temperature on the pump motor and the chiller operation.
Check the precise operation of flow detection switch.
