Microprocessor controlled demand defrost for a cooled enclosure |
摘要 |
A refrigerated device having a cooled enclosure and an evaporator through which refrigerant is circulated. An air temperature sensor adapted to generate an air temperature signal indicative of air temperature within the enclosure is provided. A refrigerant temperature sensor adapted to generate a refrigerant temperature signal indicative of refrigerant temperature is provided. A programmable controller adapted to compare the air temperature signal and the refrigerant temperature signal to calculate a difference between the air temperature and the refrigerant temperature is provided. The controller initiates a defrost routine for removing condensate from the evaporator if the difference between the air temperature and the refrigerant temperature is greater or equal to a defrost threshold. Also disclosed are methods for defrosting a refrigerated device and for detecting condensate accumulation.
