- the conventional evaporator structure with horizontal, each by a
- the evaporator at least in the lower region of the evaporator, preferably replaced by a structure in which rectilinear sections of the refrigerant line are oriented at an acute angle to each other and diverge up and down from a curve section connecting them.
- the straight sections are preferably inclined at most 5 ° to the horizontal, so that the distance between the rectilinear sections at their end remote from the curve section connecting them is not too great and good utilization of the evaporator surface is ensured.
- the inclination of the refrigerant channels in the lower area should not be less than 0.2 °, to ensure that a possibly not exactly horizontal installation of the refrigerator prevents the continuous escape of small steam bubbles.
- Fig. 1 is a schematic representation of an inventive
- Condenser 2 is connected via a dryer cartridge 3 with a capillary 4, which - partly running within a suction line 5 - leads to an evaporator 6.
- the evaporator 6 is essentially composed of two aluminum sheets, a flat sheet, the surface of a rear wall of an inner container of the
- the refrigerant line 7 of the evaporator 6 contains a mixture of liquid and gaseous refrigerant.
- a heating of the evaporator 6 taking place in the stoppage phase of the compressor 1 causes the liquid refrigerant to evaporate in its lower region 12. Bubbles forming thereby rise continuously and silently along the line sections 13, 14 until they reach the surface of the liquid.
- Refrigerant piping which is required to allow the gas bubbles to rise, is only fractions of a degree, is a lower limit to the slope substantially dictated by the requirement that the climb must still be possible even if the substrate on which the refrigeration device is located is not exactly horizontal.
