Complete Solution for Central Air Conditioning System Retrofit in Mexican Office Buildings (American Standard Distribution Transformer)

Ⅰ. Project Background & Pain Point AnalysisThe Mexican office building utilizes a 15HP commercial central air conditioning system originally powered by a single-phase 220V grid. Due to the lack of 380V three-phase driving voltage, the compressor startup current exceeds overload limits (measured at 3.2× rated current), causing refrigeration efficiency to plummet to 40%, accompanied by: Motor winding temperature rise exceeding standards (ΔT > 65°C), reducing insu
