Summary:PURPOSE: A cooling and heating apparatus using hydrogen storage alloys, and a method for controlling the same are provided to reduce power consumption and improve the efficiency of compressors by controlling the compressors and a system according to a compression ratio and a discharge pressure of each compressor measured by pressure sensors in real time. CONSTITUTION: A plurality of reactors(10,15) are filled with a hydrogen storage alloy inside. A plurality of ventilating fans(30,35) forcibly absorb the external air for exchanging heat through the pair of reactors, and forcibly send the air into a room or out of the room. A plurality of hydrogen passage pipes(21-25) are connected with the reactors, wherein hydrogen flows inside. A plurality of compressors(40,45) are connected with the hydrogen passage pipes and are connected in serial for generating sending power to forcibly send the hydrogen inside the hydrogen passage pipe. A passage control valve(50) is installed in each hydrogen passage pipe for controlling a sending direction of the hydrogen. A plurality of pressure sensors(71,72,73) are installed in the hydrogen passage pipes for sensing a pressure of hydrogen flowed into or discharged from the plurality of compressors. A bypass passage(60) induces the hydrogen discharged from the plurality of compressors to a discharge side hydrogen passage pipe of the final compressor. A switch valve(65) is connected with the bypass passage for allowing or interrupting flow of hydrogen. 본 발명은 냉난방장치에 관한 것으로, 압축기를 다단으로 구성하고 각 압축기로 유입 및 토출되는 수소 냉매의 압력을 감지하여 각 압축기 또는 유로제어밸브의 작동을 제어함으로써 전체적인 냉난방 시스템의 효율을 향상시킨 것이다. 이를 위해 본 발명은, 수소 저장합금이 충전된 한 쌍의 반응기와; 외기를 실내 및 실외로 강제 송풍시키는 송풍수단과; 수소가 유동하는 수소 유로관과; 수소 유로관 내의 수소를 강제 압송하도록 여러 단계에 걸쳐 압송력을 발생시키는 직렬로 연결된 복수개의 압축기와; 상기 수소 유로관에 설치되어 수소의 압송 방향을 제어하는 유로제어밸브와; 상기 각 압축기로 유입 및 토출되는 수소의 압력을 감지하여 콘트롤러에 전달하는 복수개의 압력감지수단과; 상기 각 압축기에서 토출된 수소를 다음 압축기로 보내지 않고 바로 최종 압축기의 토출측 수소 유로관으로 유도하는 바이패스유로 및; 상기 각 바이패스유로 상에 연결되어 수소의 유동을 허용 및 차단하는 개폐밸브를 포함하여 구성된 수소 저장합금을 이용한 냉난방장치가 제공된다.
