Abstract:
Establishes the calculation models of energy consumption of the water chiller and pump in fan-coil unit air coditioning chilled water system, and calculates the total energy consumption under different supply water temperatures. Under the calculation condition of this article, when the head of water pump is between 15 m and 33.2 m, and the chilled water supply temperature is 7 ℃ and the supply-return water temperature difference is 5 ℃, the system energy consumption is the lowest; when the head of water pump is between 33.2 m and 40 m, and the chilled water supply temperature is 6 ℃ and the supply-return water temperature difference is 6.17 ℃, the system energy consumption is the minimum.
