APPARATUS FOR IMPROVING STARTING PERFORMANCE, A COOLING MACHINE, AND A COOLING SYSTEM EQUIPPED WITH THE SAME, CAPABLE OF IMPROVING THE STARTING PERFORMANCE WITHOUT USING AN ADDITIONAL AIR SUPPLYING APPARATUS FOR STARTING

摘要

PURPOSE: An apparatus for improving starting performance, a cooling machine and a cooling system equipped with the same are provided to use a bypass path and a check valve, thereby quickly completing starting under inlet/outlet pressure conditions for the wide range of cooling machines and systems applied with an air bearing.;CONSTITUTION: An apparatus(100) for improving starting performance includes a compressor(130), a turbine(140), a fluid bearing, a bypass path(210), and a check valve(220). The apparatus is connected to a cooling machine. The turbine is connected to the compressor by a flow path. The fluid bearing bears a rotary shaft at the turbine. The bypass path is branched from the inlet of the compressor and is connected to the flow path so that a fluid is directly supplied to the turbine by skipping the compressor when starting the cooling machine. The check valve is placed on the bypass path. The apparatus is equipped with first and second inlets(214,213) and first and second outlets in order to form the bypass path. A first heat exchanger(110) is mounted on the inlet of the compressor. The fluid flows in the first heat exchanger so that heat exchange between the fluid and a coolant is implemented in the first heat exchanger. A second heat exchanger(160) is placed on the flow path with which the compressor and the turbine are connected to each other.;COPYRIGHT KIPO 2013;[Reference numerals] (110,160) Heat exchanger; (130) Compressor; (140) Turbine
