COOLING AND HEATING APPARATUS USING HYDROGEN STORAGE ALLOYS

摘要

PURPOSE: A cooling and heating apparatus using hydrogen storage alloys is provided to prevent oil from moving into reactors by discharging an oil-removed hydrogen refrigerant. CONSTITUTION: A pair of reactors are filled with a hydrogen storage alloy inside. A plurality of ventilating fans forcibly absorb the external air to forcibly send the air into a room or out of the room. A hydrogen passage pipe(20) is connected with the reactors, wherein hydrogen flows inside. A compressor(40) is connected with the hydrogen passage pipe to compress hydrogen. A passage control valve controls a sending direction of hydrogen. A discharge muffler(45) is installed in the compressor for reducing a pressure pulse of a mixed fluid of a hydrogen refrigerant and oil, and separating the oil from the mixed fluid to discharge the oil. An oil recovery pipe(46) is connected with one end of the discharge muffler to recover the oil separated from the mixed fluid to an oil storage part of the compressor.
