Oversized single zone air conditioning units often lead to extremely poor space comfort and high humidity. A "bigger is better" philosophy is not always better and can lead to many comfort and operational problems. A psychometric analysis demonstrates the oversized impact on space comfort. Common design and operational reasons that drive oversizing is presented based upon actual field experiences. This session presents the results from NIST research that shows oversized residential cooling systems can lead to greater discomfort. Real world commercial case studies showing successful retrofit strategies without replacing equipment is presented.
