Claims16
A refrigerator comprising:
- at least one preservation compartment;
- a first evaporator comprising an extendable tube having a first portion wound around a support and a second portion unwound from the support, wherein the tube is extendable by unwinding the tube from the support to decrease the size of the first portion while increasing the size of the second portion.
A refrigerator comprising:
- at least one preservation compartment;
- a chamber separate from the at least one preservation compartment and in communication with the at least one preservation compartment through an aperture;
- and
- a first evaporator located in the chamber and comprising an extendable spiral-wound tube portion having an extended portion and a non-extended portion, with the length of the extended portion defining an effective cooling length, wherein the effective cooling length can be varied by selectively winding or unwinding the non-extended portion around a support to vary the length of the extended portion to change the cooling capacity of the evaporator.
