Micro-channel evaporator with frost detection and control

摘要: A refrigerant vapor compression system includes an evaporator having a plurality of longitudinally extending, flattened heat exchange tubes disposed in parallel, spaced relationship. Each the has cross-section and defining discrete, extending flow passages. One or more frost detection sensor(s) is/are installed operative association with for detecting presence frost/ice formation on at one associated transfer fins. defrost is provided operatively exchanger. controller, coupled to system, selectively activates initiate cycle response signal indicative
