A scroll compressor includes a fixed scroll having a fixed wrap, and an orbiting scroll having an orbiting wrap engaged with the fixed wrap to define a first compression chamber between an inner surface of the fixed wrap and an outer surface of the orbiting wrap, and to define a second compression chamber between an inner surface of the orbiting wrap and an outer surface of the fixed wrap. A rotation shaft is provided with an eccentric portion at one end thereof to drive the orbiting scroll. A protruding portion protrudes inwardly from an inner end of the fixed wrap, and contacts the orbiting wrap. A distance between a center of the eccentric portion and a tangent line at a contact point between the protruding portion and the orbiting wrap at an end of the first compression chamber is smaller than a radius of the eccentric portion.

Scroll compressor

A heat pump including a boiler is disclosed. The heat pump may include a quick-hot-water-supply tank and the boiler, which may be operated selectively based on a temperature of external air or an electric power rate per unit heat quantity.

Heat pump

An outdoor unit for an air conditioner according to an exemplary embodiment of the disclosure, comprising: a case forming shape and having a suction port suctioning outside air and a discharge port discharging the suctioned air; a heat exchanger accommodated inside the case; a fan that is accommodated inside the case and forcibly circulate air; and a louver assembly revolvably mounted in the case so as to selectively open and close the discharge port.

Outdoor unit for air conditioner

A heat pump-type hot water feeding apparatus includes a cooling cycle circuit, a heat storage tank, and a hydro kit heat exchanging unit, wherein the hydro kit heat exchanging unit is connected to the cooling cycle circuit, wherein during a heat storage mode operation that stores heat in the heat storage tank, heat of the first heat transfer fluid, which is heat exchanged in the first heat exchanger, is stored in the heat storage tank or heat of the first heat transfer fluid, which is heat exchanged in the first heat exchanger and heat of the second heat transfer fluid, which is heat exchanged in the second heat exchanger, are simultaneously stored in the heat storage tank.

Heat pump-type hot water feeding apparatus

A refrigerator is provided which can individually cool a freezing chamber and a refrigerating chamber by dividing a heat exchange region of an evaporator into a freezing chamber side region and a refrigerating chamber side region, forming individual circulation passages for supplying cool air from each region to the freezing chamber and the refrigerating chamber, and forming a freezing chamber fan and a refrigerating chamber fan on each circulation passage. Further, a method for controlling operation of the same is provided which can efficiently perform a cooling operation and reduce power consumption by effectively controlling the operations of each component.

Refrigerator, and method for controlling operation of the same

A surface treatment system is disclosed to form a deposition layer at a surface of an object of surface treatment by using a deposition reaction in which an electrode () for applying power to form a deposition reaction in the deposition chamber () is installed between an inner wall () of the deposition chamber () and an object of surface treatment () and further includes a cooling unit () installed at the inner wall () of the deposition chamber () facing the electrode () and cooling ambient thereof.

Surface treatment system and method

Disclosed are a surface treatment system that includes a deposition chamber () for forming a deposition layer at a surface of an object of surface treatment (); a carrier () for carrying the object of surface treatment () by mounting thereon, and a power applying unit () for forming a deposition reaction by applying a power to the object in the deposition chamber (), wherein the power applying unit () includes a fixed power applying unit () installed in the deposition chamber () and connected to an external power source (); and a movable power applying unit () installed at the carrier () for being electrically connected to the fixed power applying unit () movably as the carrier on which the object of surface treatment () is mounted goes into the deposition chamber and thereby applying a power to the object of surface treatment mounted on the carrier by contacting thereto.

Surface treatment system and method thereof

A surface treatment system in which gas for a deposition reaction is injected into a deposition chamber and power is applied to form a deposition reaction to form a deposition layer at a surface of an object or surface treatment, wherein the deposition chamber has a plurality of deposition spaces disposed in parallel and a convey unit for conveying one or more objects of surface treatment to each deposition space or discharging the objects of surface treatment from each deposition space after a deposition reaction.
