Abstract

In order to reduce the energy consumption of the Large-scale Air-conditioning system, this paper studies the influence on system energy consumption of different supply chilled water temperature, and the optimum temperature of supply chilled water was obtained. By through established the relation equation for the total energy consumption of chilled water supply temperature, the variation rules of the total energy consumption of the Large-scale air-conditioning with the chilled water supply temperature change were analysed. As a result, the optimum temperature of supply chilled water was 8.3153 ℃ when the total energy consumption is the minimum of the system under a certain loading.
