摘要： PURPOSE:To permit operation with a load continuously by obtained electric energy by a method wherein the load is controlled in accordance with the electric energy obtained from solar energy. CONSTITUTION:When the amount of sunshine is much and operation can be continued by the output electric power of a solar battery 36, a changeover switch 14 is put OFF by a command from an operation mode setter 60 and another changeover switch 62 is switched to the side of a settable temperature operating circuit 58. In this case, the amount of sunshine is detected by an amount of sunshine sensor 54 whereby the available maximum output electric power of the solar battery 36 is operated. The operated value is inputted into a number of rotation operating circuit 64 and the operation mode setter 60. When it is decided that the operation of a compressor 28 becomes possible by only the output power of the solar battery 36 at a set temperature in the operation mode setter 60, the changeover switches 14, 62 are switched by a command from the operation mode setter 60 and operation effected by the solar battery 36 only is started.

摘要： PURPOSE:To construct a system saving labor and time for laying a control signal transmission line and excellent in user's operability of a load in the load control system capable of executing the remote control of power consumption. CONSTITUTION:A control signal for a load 4 is radio-transmitted by using the system of a cordless telephone 7. Since the load control system is provided with a function capable of sending a control signal to a slave set, a remote control means for a load user is obtained. Since the control signal to the load 4 can be wirelessly transmitted, necessity for newly laying a signal transmission line can be eliminated. Since the load 4 can be remotely controlled by means of the cordless telephone slave set, the user's operability of the load can be improved.

摘要： PURPOSE:To permit the supply of heat having a temperature higher than the temperature of recovered waste heat of a power generating plant, by a method wherein the title system is provided with a heat accumulating type heat pump, accumulating excessive waste heat from the power generating plant and capable of radiating heat having a temperature higher than the temperature of the waste heat recovered from the power generating plant. CONSTITUTION:When heat is not necessitated in an instrument 9 utilizing hot-water, valves 5, 8 are regulated to heat a hydrogenated metal 9 in a heat accumulating tank 7 by all of recovered waste heat through a heat exchanger 6 for a heat source and release hydrogen with a pressure equilibrated to the temperature. The hydrogen is sent to and stored in a hydrogen gas tank 13 through a releasing hydrogen pipeline 17. Next, when the supply of heat to an instrument 12 utilizing high temperature hot-water becomes necessary, the hydrogen, stored in the hydrogen gas tank 13, is pressurized by a compressor 16 to a pressure higher than the equilibrium pressure to a necessary temperature to supply it to the heat accumulating tank 7. In this case, the hydrogenated metal 9 absorbs the hydrogen and generates heat having a temperature equilibrated to the pressure of the hydrogen, then, the heat is taken out by a heat exchanger 10 for the instrument utilizing the heat and is supplied to the instrument 12 utilizing high-temperature hot-water.

摘要： PURPOSE:To reduce the necessary heat source capacity of a water injection system by connecting both of a high temp. region and a low temp. region by a flow passage having a small equivalent flow passage area. CONSTITUTION:A tank 10 filled with low temp. cooling water as a core cooling system for emergency and a tank 12 filled with cooling water set and adjusted to high temp. by a water temp. control system 11 (heater) are connected by a flow passage 13 having a small cross-sectional area such as piping and the tank 10 is connected to the liquid phase part in a pressure vessel 3. At the time of the destruction accident of piping, the pressure in the tanks 10, 12 are lowered as the pressure in a pressure vessel is lowered. When the pressures reach the saturated pressure of the high temp. water in the tank 12 or less, the cooling water in the tank 12 is boiled under reduced pressure. At this time, the low temp. cooling water in the tank 10 is injected in the pressure vessel 3 through piping by the volume change (expansion) from a liquid phase to a gaseous phase to achieve the keeping of the cooling and submergence of the core.
