This freshly rebuilt reciprocating compressor is destined for a large commercial chiller. Chillers chill water for air conditioning. Compressors compress refrigerant vapor and pump the compressed refrigerant to the condenser to be condensed into a liquid. The compressor provides compression which is an integral part of the refrigeration process. The old compressor was condemned for electrical burn out. The windings in the old compressor burned up and caused the circuit breaker to trip. Read more below.

HVAC Compressors (hermetic and semi-hermetic HVAC compressors) have electric motors inside of them. All electric motors have windings inside them. These windings are made of copper and are wound in loops. When electricity passes through these windings they provide an electromagnetic field that causes the rotor in the electric motor to turn. These windings are coated with shellac to prevent the copper windings from touching one another. One reason compressor motors fail is because the shellac on the windings deteriorates and the copper windings touch causing a dead short in the windings. An HVAC Technician can determine if the HVAC compressor windings are shorted using a meter.
