220kV变电站不同空调方案的全寿命周期费用比较

The Comparison of Life Cycle Cost about Different Air-conditioning Scheme in 220kV Substation

以220kV变电站中35kV配电装置室内空调选型方案为背景,比较分体空调方案与多联空调方案的全寿命周期费用。对于变电站内的空调房间,从全寿命周期费用角度考虑应尽量采用多联空调方案。随着室内冷负荷、空调运行时间的增加,多联空调方案的全寿命周期所节省的费用也逐渐增加。

Taking the air conditioning scheme of 35kV distribution room in 220kV substation as the back ground, compare the LCC of split air conditioning scheme with variable refrigerant volume air conditioning scheme. For air conditioned rooms in substations, from the perspective of LCC,variable refrigerant volume air conditioning scheme should be used as far as possible. With the increase of indoor cooling load and operation time, the cost savings will increase accordingly.
