(54) A defrosting method


(57) The present invention develops an alternative method for defrosting the ice accumulating on the evaporator-1 (3) of a cooler device (S), provided with at least one cooling compartment (2) and at least one freezing compartment (1) that comprises compressor (5), condenser (6), evaporator (3, 4) and capillary tube units. There is at least one additional condenser (7) which is to be included in the cooling cycle of the said cooler device (S) when defrost operation is active. The said additional condenser (7) and the main condenser (6) are connected to the compressor (5) via at least one valve (9b). Thus, the valve (9b) breaks the connection between the compressor (5) and the additional condenser (7) when defrost operation is inactive, and it is ensured that the refrigerant completes the regular cooling cycle through the main condenser (6). The valve (9b) includes the additional condenser (7), positioned on the evaporator-1 (3) the ice of which is to be defrosted, in the cooling cycle by breaking the connection of the compressor (5) with the main condenser (6) when defrost operation is active.
