摘　　要：由于在安全和环保上的优势,干式变压器的应用越来越广泛,其余热利用也成为新的研究方向。以近零碳建筑为设计目标的某拟建供电局大楼为例,对该大楼所配干式变压器的余热利用方案进行设计。通过热力计算和创新低温驱动的吸收式制冷循环等方法,在技术上分析了干式变压器的余热应用于机房空调的可行性。研究结果发现,虽然干式变压器的余热是能量密度较低的低温热能,但是运用一定技术手段后仍然可以用于制冷。Due to its advantages in safety and environmental protection,dry type transformer has been widely used and its waste heat utilization has become a new research direction.The waste heat utilization scheme of dry type transformer in a proposed power supply bureau building with near zero carbon building as an example is designed.Through thermodynamic calculation and innovative absorption refrigeration cycle driven by low temperature,the feasibility of applying the waste heat of dry type transformer to air conditioning in machine room is analyzed.The results show that although the waste heat of dry transformer is low temperature heat energy with low energy density,it can still be used for refrigeration with certain technical means.
