Disclosed is a carbon nanoball for deodorization composed of a circular hollow core, and a porous carbon shell to which at least one deodorizing material selected from the group consisting of transition metal, oxidized transition metal and alkali metal salt is adhered. The porous carbon shell of the carbon nanoball for deodorization has multi layers more than 2 layers having different pore sizes, and a pore formed in an outer layer has a larger average diameter than a pore formed in an inner layer. This multi-layered carbon nanoball for deodorization may absorb various kinds of stink-generating materials together with good deodorizing capability. Thus, the multi-layered carbon nanoball may give excellent deodorizing effects by capturing and dissolving stinky substances when it used as a deodorant for various stinky daily necessaries or in houses, offices, industrial facilities and other various stink-causing circumstances.
摘要:
An operation control method for a refrigerator after a power-supply comeback due to a power-failure that performs a re-operation according to operation information stored before the power-failure. The operation control method includes the steps of: (a) reading stored operation information when power is reapplied to the refrigerator; (b) determining whether the operation information includes a compartment set temperature information and an accumulated information of a compressor operation time; (c) if the compartment set temperature information and the accumulated information of the compressor operation time are found in the step (b), automatically setting an operation mode according to the compartment set temperature information, and detecting a compartment temperature of the refrigerator and an evaporator surface temperature; (d) determining whether the compartment temperature is lower than a predetermined compartment temperature to determine a power failure of a long time, or the evaporator surface temperature is lower than a predetermined surface temperature to determine a power-failure of a long time; (e) if the compartment temperature is lower than the predetermined compartment temperature or the evaporator surface temperature is lower than the predetermined surface temperature in the step (d), accumulating a compressor operation time in addition to the stored compressor operation time; and (f) if the compartment temperature is not lower than the predetermined compartment temperature and the evaporator surface temperature is not lower than the predetermined surface temperature in the step (d), deleting the stored compressor operation time accumulation information, and newly accumulating a compressor operation time.
