Experimental research on energy saving effects of variable frequency chilled water system of air conditioning

Taking fan coil unit water system as study object, develops simulative software for calculating water system pipe network of air conditioning and simulates the energy saving effects of variable frequency chilled water system under different frequencies. Experimental result shows that the simulation result is closed to the experimental data. The lower the frequency is, the better the energy saving effect is, and the actual power consumption of the pump is not fit for cubic law in variable conditions.
