The present invention relates to an organic polymer adsorbent, an organic polymer adsorbent composition, and a method for preparing an organic polymer adsorbent and, more specifically, to an organic polymer adsorbent to be used for a ventilation device such as a desiccant dehumidifier. According to the present invention, an adsorbent material is changed to an organic polymer adsorbent such that the mechanical stability and durability of the material itself can be ensured, and the specific surface area of interconnected inner pores and adsorbents and the size of formed pores can be controlled since toluene is contained as a pore generator of the adsorbent. Therefore, the adsorbent of the present invention has superior adsorption performance over that of other conventional organic polymer adsorbents containing a salt-type carboxyl group and has remarkably improved desorption performance, and thus has an effect of very remarkable energy efficiency.

A heat exchanger is provided that is operated in a cooling operation mode in which a region to be heat-exchanged is cooled by the heat exchanger or in a drying operation mode in which the heat exchanger is supplied with wind from a blowing fan. The heat exchanger includes a refrigerant pipe, a cooling fin coupled to the refrigerant pipe, and a hydrophilic coating coated on a surface of the refrigerant pipe or the cooling fin. The hydrophilic coating includes a first type transition metal oxide which becomes acidic by reacting with moisture formed on the refrigerant pipe or the cooling fin to have antimicrobial activity when the heat exchanger is operated in the cooling operation mode, and a second type transition metal oxide or a post-transition metal oxide which has antimicrobial activity when the heat exchanger is operated in the drying operation mode.

A method for operating a clothes treating apparatus comprising a hot air supplying unit provided with a heater and a blowing device, and having a drying function of drying clothes by supplying hot air into a drum by use of the hot air supplying unit, includes rotating the drum with the clothes introduced therein, and supplying hot air into the drum by using the heater and the blowing device while the drum is rotated, wherein an air flow rate supplied by the blowing device changes during the hot air supplying step.

Operating method for clothes treating apparatus

A laundry treating apparatus is disclosed. The laundry treating apparatus includes a first cabinet having a first receiving space to receive laundry, a second cabinet having a second receiving space to receive laundry, the second cabinet being separated from the first cabinet, a partition wall located at an upper part of the second receiving space to divide an interior of the second cabinet, a discharge unit to discharge air from the first receiving space and air from the second receiving space, and a supply unit including a supply duct to selectively supply air to the first receiving space and the second receiving space and a supply fan provided in the partition wall such that the supply fan is located in the second cabinet to move air from the second receiving space to the supply duct.

Laundry treating apparatus

A laundry treatment apparatus and a method for controlling a laundry treatment apparatus are provided. The method may include supplying alternating current at a predetermined first frequency to a compressor; measuring a first time a temperature of refrigerant discharged from the compressor; measuring a second time a temperature of the refrigerant discharged from the compressor, when a predetermined first reference time has passed after the measuring the first time of the temperature of the refrigerant discharged from the compressor; and controlling the first frequency of the alternating current based on a difference between the temperature measured the first time and the temperature measured the second time.
