Abstract: | Taking a hospital in Chongqing as a case study, the energy-consuming equipment are counted with energy audited, it's obtained that the energy consumption per unit area is 136.82kW·h/㎡·a, and the classified building energy proportion and monthly electricity consumption are calculated to ana-lyze the existing problems. The major renovation goal, thus, for the building energy saving is central air-conditioning system. Combined with the test statistics, the energy consumption value and proportion of each part of the air-conditioning system are calculated, so as to determine the right renovation scheme to install the intelligent trip device, water pump frequency conversion and cooling tower automation. The renovated air-conditioning system has the energy efficiency of 39.85%, a proportion of 8.96% in total electricity consumption of the building, saving up to 407,300 yuan for economic benefit. |
