  • Patent number: 11508801
    Abstract: A display device includes: scan lines extending in a first direction; data lines extending in a second direction intersecting the first direction and receiving data voltages; first driving voltage lines extending in the second direction and receiving a first driving voltage; second driving voltage lines extending in the second direction and receiving a second driving voltage different from the first driving voltage; and pixels connected to the scan and data lines. Each of the pixels includes first, second, and third subpixels arranged in the first direction. The first driving voltage lines and the second driving voltage lines are alternately arranged in the first direction. A location of the first driving voltage line in a first pixel differs from a location of the second driving voltage line in a second pixel. The second pixel is adjacent to the first pixel in the first direction.

  • Patent number: 11306912
    Abstract: In the present invention, a recuperator is used in a refrigerant cycle to make a heat exchange between a refrigerant generated in a condenser and a refrigerant before flowing into a compressor, thereby supercooling the refrigerant to minimize the quality of the refrigerant introduced into an evaporator, elevating temperatures at an inlet and an outlet of the compressor, and increasing condensed heat of the condenser. In the present invention, a recuperator is used to increase condensed heat of the condenser, leading to increasing the heat which circulation water circulating in a steam producing cycle receives from the condenser, whereby steam production efficiency can be improved.

  • Patent number: 9982918
    Abstract: A heating medium supplied to an evaporator is used to heat lubricant oil in a screw compressor before the screw compressor starts up, and no additional heater for heating the lubricant oil in the screw compressor is required. When the screw compressor operates, the heating medium discharged from the evaporator after the evaporator is heated by the heating medium, is used to cool the lubricant oil. The lubricant oil heated by a lubricant oil heat exchanger is directly injected into a motor and a screw rotor so that introduction of a liquid refrigerant into a compressive chamber is reduced when the screw compressor starts up later. The lubricant oil introduced into the motor is discharged toward a lubricant oil storage portion before the screw compressor starts up so that the liquid refrigerant is prevented in advance from being introduced into the screw rotor when the screw compressor starts up.
