CDMHHP COOLING SYSTEM USING TWO OF DIFFERENT METAL HYDRIDES

摘要

PURPOSE: A CDMHHP(Compressor-Driven Metal Hydride Heat Pump) cooling system using two of different metal hydrides is provided to increase energy efficiency. CONSTITUTION: A cooling system includes a low pressure reaction part(10) comprising a low pressure reactor(12) using low pressure reactionary metal hydride storing and discharging hydrogen at relatively low pressure and a first blower(14) supplying the low pressure reactor with air to be cooled; a high pressure reaction part(20) comprising a high pressure reactor(22) using high pressure reactionary metal hydride storing and discharging hydrogen at higher pressure relatively to the low pressure reactor and a second blower(24) supplying the high pressure reactor with air to be cooled; a connecting pipe(32) connecting the low pressure reaction part and the high pressure reaction part to transfer hydrogen; a first valve(30a) connected to the middle of the connecting pipe to open and close moving path of hydrogen; a hydrogen transfer device, a compressor(30) having an inlet and an outlet connected to both ends of the first valve, respectively; a second valve(30b) and a third valve(30c) connected between both of the ends of the first valve and the inlet and the outlet of the compressor, respectively, to open and close moving path of hydrogen; and a control part(35).
