REFRIGERATING SYSTEM FOR DOMESTIC REFRIGERATING APPLIANCES

摘要

The invention relates to a refrigerating system for domestic refrigerating appliances which is comprised of a hermetic motor compressor (10), of a condenser (2) that is connected on the pressure side to said motor compressor (10), and of a capillary tube (42) which is connected on the outlet side to the condenser (2) and which is in thermal contact with the suction line (44) of the motor compressor (10). The refrigerating system is also comprised of an evaporator (3) which is connected to the capillary tube (42), is thermally coupled to a PCM device, and which is connected on the suction end to the motor compressor (10), and of a fan for intensifying the convection in the refrigerator section of the refrigerating appliance. The outlet of the evaporator (3) is connected to an undercooling accumulator (40) on the suction end which, in turn, is connected to the air intake (44) of the motor compressor (10). Said motor compressor (10) and undercooling accumulator (40), which is located on the suction end, are mounted on a frame and are flexibly supported and enclosed by a sound insulation cover. The maximum overall height of said frame including the components and the sound insulation cover mounted thereon corresponds to the base height of the refrigerating appliance. The invention additionally relates to the design of the hermetic refrigeration compressor (10), of the reciprocating compressor piston and of the undercooling accumulator located on the suction end.
