Abstract:
A steam dryer control method controls the amount of water supplied to a heater to adjust an amount of steam. The steam dryer control method includes turning on a steam heater, turning on a water supply valve and counting the number of lapses of unit water supply duration at any time when the unit water supply duration elapses, and rotating a drum when the number of lapses of the unit water supply duration reaches a preset number.
Abstract:
A separation, purification and recovery method of SF6, HFCs or PFCs is disclosed, which comprises a step for forming a gas hydrate including components in addition to SF6, HFCs or PFCs. It is possible to separate and recover fluoro-gas at a much lower cost as compared to a conventional method for thereby obtaining an economical effect and preventing an emission of SF6, HFCs or PFCs which corresponds to Non-CO2 having a higher earth warming index, which leads to preventing an earth warming phenomenon. So, the present invention might be widely applied.
Abstract:
A washing machine is disclosed. The washing machine includes a detergent receiving part, a supply pipe communicating with a water supply pipe and supplying wash water, an on-off valve between the detergent receiving part and the supply pipe, and a controller opening or closing the on-off valve corresponding to a proceeding washing cycle to supply a preset amount of detergent to the supply pipe.
