- •
We have developed the load responsive control of the evaporating temperature for the VRF system.
- •
We have created the VRF system model that simulates the change in the evaporating temperatures using the EnergyPlus runtime language.
- •
The experiment results indicate that the energy efficiency of the VRF system has been improved by 12% through the use of the developed algorithm.
- •
Our simulation results demonstrate that the annual cooling energy consumption is lowered by 14%.
