COOLING AND HEATING DEVICE USING HYDROGEN STORAGE ALLOY

摘要

PURPOSE: A cooling and heating device using a hydrogen storage alloy is provided to prevent the size of a total system from being enlarged even if each reactor gets larger and to increase the efficiency of a compressor by making the compressor for pumping hydrogen refrigerants in multi-stage. CONSTITUTION: A cooling and heating device using a hydrogen storage alloy is composed of a pair of reactors(10,15) filled with the hydrogen storage alloy; blowing devices(30,35) for forcibly sending external air to the indoor and outdoor after forcibly sucking in the air and heat-exchanging the air through reactors; a hydrogen passage(20) coupled to each reactor to flow hydrogen; a plurality of compressors(40) connected to the hydrogen passage and coupled in series to generate sending force in several stages to forcibly flow hydrogen in the hydrogen passage from one reactor to another; at least one intermediate cooling unit disposed between each compressor to cool hydrogen discharged from compressors; and a passage control valve(50) installed to the hydrogen passage to control the forcible-sending direction of the hydrogen.
