Abstract: A heat converter according to one embodiment of the present invention comprises: a plurality of unit modules respectively arranged in a first direction and a second direction that intersects the first direction; and a frame, which supports the plurality of unit modules, allows cooling water to flow in through one surface arranged in the first direction, and allows the cooling water to be discharged through the other surface arranged in the first direction, wherein each unit module includes: a cooling water passage chamber having first and second surfaces arranged to be spaced in the first direction, third and fourth surfaces arranged to be spaced in a third direction that intersects the first direction and the second direction, a fifth surface arranged to be spaced in the second direction such that cooing water flows therein, and a sixth surface from which cooling water is discharged; a first thermoelectric module arranged on the first surface; and a second thermoelectric module arranged on the second surface

Abstract: A light source module and an air conditioner including the light source module. The light source module includes: at least one light source emitting sterilizing light in a wavelength band capable of sterilizing pollutants; a substrate on which the light source is mounted, the substrate being electrically connected to the light source; and a light guide guiding a traveling direction of the sterilizing light emitted from the light source. The light guide may guide the sterilizing light such that a beam angle of the light source module becomes narrower than a beam angle of the light source.

Abstract: The present invention relates to a styrenic thermoplastic resin composition, and more particularly to a styrenic thermoplastic resin composition comprising a non-halogen flame-retardant having superior flame-retarding properties and impact strength. The present invention provides a flame-retarding styrenic thermoplastic resin composition comprising a) 100 weight parts of a base resin comprising i) 10 to 50 weight parts of a rubber-modified styrene-containing graft copolymer, ii) 5 to 20 weight parts of phenol novolac resin, and iii) 20 to 70 weight parts of a styrene-containing copolymer; and b) 5 to 20 weight parts of an aromatic phosphate. In addition, the a) base resin may further comprise iv) 10 to 40 weight parts of a thermoplastic polyurethane resin.
