Research on the transformation of variable frequency pump of cooling system under low load rate in a data center
TRNSYS simulation platform is used to establish the energy consumption model of the cooling system in the data center.Based on the model,the frequency conver-sion transformation of the water pump is analyzed and studied.The results show that un-der the low load operation with the load rate of 10%~25%in the IDC,the pump energy consumption of the refrigeration system in the IDC is reduced by 150 kW~168 kW.The COP of chiller is increased from 6.2 to 8.0.Using variable frequency pump can effectively reduce PUE,up to 0.36.
