HVAC distributor cfm Distributors recently developed a list of items to test and/or questions to ask when dealing with sites that have experienced multiple failed compressors. The first step consists of determining the compressor’s mode of failure. Was it electrical or mechanical? This piece focuses on mechanical failures. Read our piece on electrical failures.
Airflow is one of the leading causes of failure for compressors. Most manufacturers recommend a nominal airflow of 400 cfm/ton. Enough airflow is needed to ensure adequate heat transfer to boil the refrigerant off in the evaporator so that the compressor does not become slugged with liquid.
