One of the worst enemies of a compressor is liquid refrigerant, so technicians should make sure the refrigeration system has proper superheat in order to protect the compressor from damage that can occur from flooding or slugging.
Even though the circulated refrigerant is the working fluid required for cooling, lubricant or oil is needed for lubrication of the compressor’s moving mechanical parts.
Inexperienced service technicians have a tendency to add refrigerant to a troubled system in order to remedy a problem. Because of this, many systems are operating with an overcharge of refrigerant.
For new technicians who need an early hands-on experience in a controlled setting, or experienced technicians who need to work through real-world problems, this seminar offers a day of hands-on experience.
