Zusammenfassung:	In general the present invention provides a refrigeration system and a method of controlling the refrigeration system. The system includes a coolant circuit having in series a compressor, a metering device, an evaporator coil, and sensors for determining the coolant temperature and pressure within the circuit. The system also includes a defrost system that includes a fan and/or a resistive heating element. The present invention also provides a method of operating the refrigeration system to protect the individual components such as the compressor from damage from flooding with liquid coolant. Additionally, the operating method provides a more efficient operation by using a self-adaptive defrost sequence and rapid startup sequences after the defrost periods.
