Abstract (en)
[origin: WO2009010839A2] A refrigeration circuit (3) for household appliances comprises a compressor (4) suitable for compressing a predetermined cooling fluid and for allowing the circulation thereof within said circuit (3), a first heat exchanger (5) or condenser in fluid communication with the compressor (4) for allowing the cooling and the consequent condensation of the cooling fluid going through, and a second heat exchanger (7) or evaporator in fluid communication with the first exchanger (5) through a circuit with a special device (6) suitable for decreasing the pressure of the cooling fluid at a space (2) to be cooled (normally inside the refrigerator). The second exchanger (7) allows the cooling fluid to evaporate, absorbing heat, thus cooling the space (2) and returning through the tubing (17) to the compressor (4). The cooling fluid circulates from the compressor (4) towards the first exchanger (5), from the latter towards the second exchanger (7) and then returns to the compressor (4) for a subsequent cycle. At least one of the heat exchangers (5, 7) comprises a plastic tubing (9), at least a portion whereof exhibits such corrugated profile as to impart flexibility thereof and/or increase the thermal exchange surface.
