Abstract: PURPOSE: A heat pump system and a control method thereof are provided to reduce energy consumption of a compressor and improve driving performance while minimizing the speed reduction loss, the restarting loss, and the acceleration loss of the compressor. CONSTITUTION: A heat pump system comprises an auxiliary refrigerant supplying unit(150). The auxiliary refrigerant supplying unit comprises a bypass pipe(160), a first control valve(170), a second control valve(180), and a high pressure insulation cylinder(190). When the partial load operation of a compressor is performed, some quantity of the refrigerant discharged from the compressor is filled in the high pressure insulation cylinder and in case the restarting the compressor is performed, and when the compressor restarted, the refrigerant filled in the high pressure insulation cylinder is supplied to the compressor.

Abstract: PURPOSE: A manufacturing device for a nano sintered body with directionality and a manufacturing method thereof are provided to have a uniform directionality and form a rod shaped sintered body by forming a high speed flow field in a sintering process of the nanoparticles. CONSTITUTION: A manufacturing device for a nano sintered body with directionality comprises a sintering furnace(100) which includes a blowhole(120) and an exhaust pipe(130), a stage(110) which is installed inside the sintered body and is used for installing a base substrate(600), a gas passage(200) which forms a pulmonary circulatory circuit, a blower(300) which is installed inside the sintering furnace in order to form a gas flow field, and a heater(400) for heating inside the sintering furnace. A hollow part which is used as a gas channel is formed inside the gas passage, and the gas passage interlinks the blowhole with the exhaust pipe at outside the sintering furnace. The surface of the base substrate is arranged to be inclined in accordance with the flow direction of gas which is provided to the base substrate.
