Abstract
1297065 Defrosting GOTTLOB BAUK. NECHT ELEKTROMOTORENBAU 16 April 1970 [23 April 1969] 18179/70 Heading F4H In a compression-condensation refrigeration system having two evaporators, a maincompartment evaporator 18 in series with a freezer compartment evaporator 19, the main evaporator 18 is defrosted by the warm refrigerant, still flowing through a capillary tube connection 14 between a drier 13 and the evaporator 18 after the compressor 11 has been turned off, entering the evaporator 18, expanding and forcing the refrigerant remaining in the evaporator along duct 25 and past a peak gate or barrier 28 to the freezer evaporator 19. As shown, the gate 28 is disposed higher than the accumulator 20 and also higher than the conduit system of the freezer evaporator 19 arranged between the accumulator 20 and the gate 28. The capillary tube 14 is introduced into the evaporator 18 at the highest location thereof, so that the refrigerant flows downwardly in the tube coil 17. In operation, upon de-energizing the compressor 11, under the control of thermostat 37, the forced circulation of the refrigerant is interrupted. The liquid, warm refrigerant flows from the capillary tube 14 into the cooler evaporator 18 where it evaporates; the vapour pressure so formed forces the column of liquid refrigerant accumulating at 23 from the evaporator 18 and over the barrier 28.
