<p>A REFRIGERATING MACHINE HAVING TUBE-COOLED EVAPORATOR & AIR-COOLED EVAPORATOR INCLUDES A REFRIGERATING DEVICE (1) AND A DEFROSTER (4). THE REFRIGERATING DEVICE (1) INCLUDES A COMPRESSOR (11), A CONDENSER (12), A RESERVOIR (13), A HEAT EXCHANGER (14), A FIRST REFRIGERATING ELECTROMAGNETIC VALVE (15A), A FIRST EXPANSION VALVE (16A), A TUBE-COOLED EVAPORATOR (2), A SECOND REFRIGERATING ELECTROMAGNETIC VALVE (15 B), A SECOND EXPANSION VALVE (16B), AN AIR-COOLED EVAPORATOR (3), AND A PLURALITY OF PIPES (10A, 10B, 10C, 10D, 10G). THE DEFROSTER (4) INCLUDES A MICRO SWITCH (41), A DOOR-OPENING RELAY, A HIGH/LOW PRESSURE SWITCH (43), A COMPRESSOR ELECTROMAGNETIC SWITCH, A DELAY RELAY (45), A SET TIMER (46), A DEFROSTING TIMER (47), A DEFROSTING CONVERSION CONTACTOR, AND A DEFROSTING RESETTING TEMPERATURE SWITCH (40). THE AIR-COOLED EVAPORATOR 3 CAN ABSORB HOT AIR ENTERING A REFRIGERATING CHAMBER (5) AND ABSORBING MOISTURE IN THE HOT AIR TO INCREASE THE FREEZING EFFECT AND REFRIGERATING EFFICIENCY IN THE REFRIGERATING CHAMBER (5).</p> |
