Title: Control of heat-exchanger with hydrogen-occluding metal built in
Inventor: KANAZAWA SHIYOU
IPC: F28F27/00
Filed: 1980-03-28
Abstract: PURPOSE: To produce the heat which is poor in dispersion and shows a desired temperature by a method wherein a differential pressure regulator is provided on a hydrogen supply duct to the captioned heat exchanger and the opening of this regulator is controlled by the difference between a temperature of the heat medium fluid taken out of the heat exchanger and the standard temperature.  
     CONSTITUTION: Hydrogen gas in a hydrogen gas vessel 11 is supplied to a heat exchanger 1 through a differential pressure regulator V 1 , occluded in hydrogen- occluding metal 2 and the heat produced is heat-exchanged with a heat medium fluid through a heat-exchanger 10 to heat the heat-medium fluid. The temperature of this heat-medium fluid is detected by a temperature detector 16 and when this temperature is lower than the standard temperature, the differential pressure regulator V 1  is opened and when it is higher, the device is closed to control the supply of hydrogen gas and to regulate the hydrogen occluding reaction of the metal. Thus, dispersion of temperature is reduced in this heat medium fluid and desired temperatures can be kept.
