Abstract: The present invention relates to a hollow fiber membrane. Provided is a cylindrical hollow fiber membrane having an inside in which a hollow part is formed along an axial direction, the hollow fiber membrane including: a first layer positioned at the outermost part so as to be exposed to the outside, and having pores formed therein to make raw water enter and leave via the pores; a second layer formed on the inside of the first layer to filter out contaminants from raw water as the raw water passes through; and a third layer to optionally separate or filter out contaminants from the raw water introduced through the second layer or introduced from the hollow part, wherein the first layer to the third layer are integrally formed; the porosity of the first layer is greater than the porosity of the third layer; and porosities are gradually decreased from the first layer to the third layer.

Abstract: A controlling method for a dryer is applied to a dryer, in which at least one of a heat pump system and a heater is selected as a heat source for heating air supplied in to a drum and a heat supply capacity of the heat pump system is more than that of the heater. The controlling method includes, when both the heat pump system and the heater are selected as the heat sources, turning the heat pump system on, turning the heater on after the heat pump system is normally turned on, turning the heater off to cool the drum and terminate drying after the drying is performed, and turning the heat pump system off after the heater is turned off.
