METHOD AND APPARATUS FOR TWO-PHASE START-UP OPERATION

摘要

A method and apparatus for removing vapor inside a liquid pump (110) at the start up operation of the pump. In addition, a method and apparatus for removing liquid inside a compressor (210) at the start up operation of the compressor. The pump and compressor each include a sensor (120, 220) attached to them that determines the physical state (i.e., liquid or vapor) of a material inside the pump or compressor. If vapor is detected inside the pump, a thermoelectric module (130) connected to the pump is powered to condense the vapor into a liquid. Likewise, if liquid is detected inside the compressor a heater (230) connected to the compressor is powered to evaporate the liquid into a vapor. After the state of the material inside the pump or compressor is changed, the pump or compressor is powered up for operation in a cooling system.
