摘要： PURPOSE:To improve a heat exchanging efficiency by a method wherein a suction pump and water-liquid separator are disposed in sequence at a supplying pipe, a discharging pipe connected to an evaporator of a freezer is connected to an ice heat accumulating water tank and an injection nozzle is disposed at an end part of the discharging pipe. CONSTITUTION:At night, less-expensive electrical power is utilized to drive a suction pump 21, cold water W and heat accumulating refrigerant liquid Wa slightly mixed to each other are sucked up through a supplying pipe 19, they are separated into cold water W and heat accumulating refrigerant liquid Wa with a water-liquid separator 22 and the cold water is circulated through a water discharging pipe. Concurrently, the heat accumulating refrigerant liquid Wa is heat exchanged through an outdoor heat exchanger or an evaporator of a freezer 18 so as to cool it. The cooled heat accumulating refrigerant liquid Wa is injected from each of injection nozzles 24 into water in the ice heat accumulating water tank 10 through a discharging pipe 23, the heat accumulating refrigerant liquid Wa exchanges heat with water to generate cold water W. This cold water W becomes a sherbet-like ice W1 as the cooling is promoted, resulting in forming a heat accumulated state. Then, at day-time, the cold water W is supplied to each of the indoor heat exchangers to perform a heat exchanging operation to generate cold air and to cool a room.

摘要： PURPOSE:To cool a rotor well even under low speed rotation, in a power plant employing a gas turbine as a prime mover, by cooling the electrical rotary machine through an independent fan when the plant is started then detecting the rotary speed of the rotor, starting current, and the starting condition such as the rotor temperature and controlling the starting operation. CONSTITUTION:When start of motoring is requested, a static starter board 1 provides a signal for informing request of the start of motoring to a forcible cooling condition controller 2. Then the controller 2 starts operation of an independent fan 3 and when the rotation of the fan 3 reaches to a predetermined value, a rotor is driven. When the rotor temperature T is settled to a normal level, the controller 2 stops operation of the independent fan 3.

摘要： PURPOSE:To quickly detect the abnormality of a circulating system by providing a sensor which measures the change of the surface heat conductivity in a spiral piping and a measuring system which detects that the surface heat conductivity is lower than a reference value with a prescribed or more frequency. CONSTITUTION:When abnormality like damage occurs in a cooling water circulating system piping 6 in a generator 1, gaseous hydrogen in the generator 1 penetrates the piping 6 from the damage position, and the extent of penetration of gaseous hydrogen is several tens times as large as that for normalcy because the pressure of gaseous hydrogen is high. Therefore, the vapor phase of gaseous hydrogen as bubbles 18 is concentrated to the inside part of the bend of a spiral piping 10 by the vapor phase separating function in the piping. At this time, cooling water (liquid phase) 17 exists in the outside part of the bend of the piping 10. Since bubbles 18 collides with a front end detecting face 5 of a surface heat conductivity sensor 14, the surface heat conductivity of the sensor 14 is reduced. When the surface heat conductivity is reduced to the reference value or lower and the frequency of this reduction exceeds a prescribed value, an alarm signal is outputted in a measuring system part 16, and the abnormality of the cooling water circulating system is detected.

摘要： PURPOSE:To improve a countermeasure against quenching and also improve quick-response excitation performance by, connecting a stabilization circuit consisting of a stabilization field winding and a connection resistor, to a superconducting field winding in parallel with each other. CONSTITUTION:Current generated from an excitation power source device 1 flows into a rotor via a collector ring 2, to excite a superconducting field winding 4 through the normal conducting circuit of the resistor and the like of a current lead 3. The stabilization circuit 7 of a stabilization field winding 5 and a connection resistor 6 connected in series is connected to the superconducting field winding 4 in parallel with each other. The stabilization field winding 5 has the current capacity of several times as large as the allowable current value of the superconducting field winding 4, and is composed of superconducting conductors having a small number of turns with a voltage required at the time of quick-response excitation which can be suppressed to the degree of a few volts by inductance. The connection resistance 6 has a resistance value to a degree that field current can be diverted to the stabilization field winding 5 by ascending voltage generated when quenching is generated at the superconducting field winding 4.

摘要： PURPOSE:To enable a load to cope with sudden fluctuation, by setting the hydrogen balanced pressure of hydrogen storage alloy contained in a case connected to the outer section of a hydrogen-gas-cooled rotary electric machine, to be the highest limit or more/ the lowest limit or less of regulated pressure in the machine. CONSTITUTION:The headers 8a, 8b at the both ends of stator coils 2 formed with hollow conductors are connected to out-of-machine pipings 10a, 10b to organize water- cooled system consisting of a tank 11, a pump 12, and a cooler 13. The tank 11 is by-passed with valves 22a, 22b and pipings 21, and current is returned to the tank 11 via the valve 22a, a case 14, and a pipe 18b. Hydrogen storage alloy 17 is contained in the case 14 and is heated/cooled with circulation water, and is set, for example, at the temperature of 60-80 deg.C and the hydrogen pressure of 5.2kg/cm , or at the temperature of 40-45 deg.C and the hydrogen pressure of 1.0kg/cm . In accordance with the fluctuation of a load, a valve 22c is opened or closed to communicate with or intercept a space section 4 in the machine. As a result, the device can cope with the sudden increment of the load, and the windage loss of a self-fan on a low load is reduced, and operation efficiency can be improved.
