Abstract: A refrigerator includes a cabinet that defines a freezing compartment and a refrigerating compartment, and an evaporator installed in the freezing compartment. The evaporator includes: an evaporator case that defines a food storage space formed therein; a cooling tube located at the evaporator case in a predetermined pattern and configured to receive a coolant; and a sheath heater disposed outside of the evaporator case to be adjacent to at least one surface of the evaporator case, the sheath heater being configured to generate heat such that heat for defrosting is transferred to the evaporator case. The sheath heater reduces the defrosting time to maintain the freshness of food, increases the cooling efficiency, and reduces power consumption. The defrosting efficiency by the sheath heater is improved by a reflection member, and an inflow of heat, generated when defrosting, into the refrigerating compartment is reduced by a heat insulation member.

Abstract: A clothes treatment apparatus includes a cooling water pipe that is placed within a condensing duct to condense humidity contained in a circulating air current. The latent heat generated from the condensation of humidity causes the temperature of the cooling water in the cooling water pipe to rise. A thermoelectric pump mechanism collects heat from the higher-temperature cooling water and uses it in heating the circulating air.
