Abstract
A refrigeration system for a chilled-product vending machine including a refrigeration compressor, a temperature sensor for detecting the temperature within said vending machine and turning the compressor ON and OFF to define a compressor cycle in response to the detection of predetermined temperature limits, an evaporator coil and evaporator fan means for blowing air across said evaporator coil and circulating said air throughout the vending machine. The system further includes a temperature-based responsive control circuitry including a product sensor for detecting the temperature of the chilled products and cycling said evaporator fan ON in response to detected product temperatures above a predetermined limit, the predetermined limit being less than the temperature required to torn the compressor ON, and a coil sensor for detecting the temperature below a predetermined limit, maintaining said evaporator fan ON during and beyond the end of the compressor cycle, and cycling the evaporator fan OFF when the temperature of the coil stabilizes above the freezing point of water.
