COOLING AND HEATING SYSTEM USING HYDROGEN STORAGE ALLOY

摘要

PURPOSE: A cooling and heating system using hydrogen storage alloy is provided to allow only hydrogen refrigerant without oil to be introduced into a reactor having the hydrogen storage alloy built therein by separating oil from fluid discharged from a compressor, mixture of hydrogen refrigerant and oil, and recovering the oil to the compressor. CONSTITUTION: The cooling and heating system includes a first reactor(10) and a second reactor(15) charged with hydrogen storage alloy; fans(30,35) forcibly introducing outside air and forcibly blowing the air into a room and the outdoors; a hydrogen channel tube(20) connected with the first reactor and the second reactor to allow hydrogen to flow therein; a compressor(40) connected with the hydrogen channel tube to generate pressure so as to forcibly feed hydrogen; a channel control valve(50) installed to the hydrogen channel tube to control feeding direction of hydrogen discharged from the compressor; and an oil separating unit separating oil from mixed fluid of hydrogen and oil discharged from the compressor to re-introduce to the compressor.
