Abstract

A refrigeration circuit (3) for household appliances comprises a first heat exchanger (5) or condenser in fluid communication with a 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. 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). 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.
