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.

Description

technical field [0001] The present invention relates to refrigeration circuits. More specifically, the present invention relates to refrigeration devices, preferably of the type used in household appliances such as refrigerators, freezers, deep freezers, refrigerators and the like. The present invention is also applicable to household appliances such as air conditioners. Background technique [0002] As is well known, refrigerators and similar refrigeration devices of conventional type comprise a refrigeration circuit in which a refrigerant medium is used to remove heat from the inside of an enclosed space, such as a refrigerator or freezer, to cool it to a predetermined temperature, and to transfer the heat to the outside. Warmer space. The above-mentioned refrigeration circuit is a closed circuit, in which the compressor, condenser, stratified or capillary device and evaporator work in order according to known working methods. Specifically, the refrigerant medium is a l...
