摘要： PROBLEM TO BE SOLVED: To reduce the pressure loss of hot water by reducing the length of a hot-water pipe by attaching a plurality of heat pipes to a base board in parallel with each other and a hot-water header which heats the heat pipes to the base board on the base-side end section sides of the heat pipes and, at the same time, to reduce the uneven temperature of the panel by improving the heat radiating efficiency of the panel. SOLUTION: A plurality of grooves 3 is formed into a base board 2 and heat pipes 4 are put in the grooves 3. A groove 6 is formed into the board 2 on the base-side end section sides of the heat pipes 4 and a hot-water header 7 which heats the heat pipes 4 is put in the groove 6. The heat of the hot water made to flow through the header 7 is transferred to the pipes 4 and evaporates a refrigerant in the pipes 4 at the base-side end sections 5 of the pipes 4. The working liquid which become vapor is circulated in such a way that the vapor flows to the main body sections 15 of the heat pipes 4, condenses while discharging heat, and returns to the base-side end sections 5. Therefore, the uneven temperature of a floor heating panel can be prevented, because the heat of the hot water can be radiated efficiently and uniformly. Since the hot water only flows through the header 7, the flow passage of the hot water can be shortened and the pressure loss of the hot water can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide the laying structure of a cooling heating panel, wherein an air reservoir is prevented from formation at the interior of a cold and hot water flow pipe. SOLUTION: A cooling and heating panel 3 is laid in an inclining state in a given spot. A cold and hot water supply header 6 is arranged on the low position side of the inclining state, and a cold and hot water discharge header 7 is arranged on the high position side of the inclination state. Cold and hot water 10 is supplied from the cold and hot water supply header 6 to a cold and hot water flow pipe 8 in the cooling and heating panel 3. Thereafter, the cold and hot water 10 is discharged through the flow pipe 8 to the cold and hot water discharge header 7. Buoyancy toward a high position based on a difference in elevation due to laying in an inclination state is generated at air generated at or braced in the internal part of the cold and hot water flow pipe 8. Thus, air in the cold and hot water flow pipe 8 is smoothly moved toward the cold and hot water discharge header 7 in a high position together with a flow of the cold and hot water 10. Air 11 discharged in the cold and hot water discharge header 7 is trapped by an air discharge valve 9 and released in the atmosphere. This constitution prevents formation of an air reservoir, by which lowering of cooling and heating efficiency is caused, at the internal part of the cold and hot water flow pipe 8.

摘要： PROBLEM TO BE SOLVED: To simplify circuit-breaker equipment for interconnection and reduce equipment expenses by improving a high-speed current limiting and interrupting device applied to an electric power system interconnecting system. SOLUTION: Separating circuit breakers are placed in an interconnecting bus 3 for interconnecting a commercial electric power system and distributed power supply units 2, and separates the distributed power supply units from the commercial system if an accident occurs in the system. As such a separating circuit breaker, a high-speed current limiting and interrupting device 9 is constituted by connecting a commutation circuit 15 and an arc extinguisher (nonlinear resistance element) 17 in parallel with a high-speed circuit breaker 11. The high-speed circuit breaker 11 performs contact parting operation when the breaker receives a signal from a fault detector 20. The commutation circuit 15 superposes high-frequency current on fault current during the contact parting operation of the high-speed circuit breaker to form a zero point. The arc extinguisher (nonlinear resistance element) 17 absorbs surge produced between the poles of the high-speed circuit breaker. An auxiliary circuit breaker (ordinary vacuum circuit breaker or switch) 26 is placed between the high-speed circuit breaker, and the commutation circuit and the arc extinguisher. After fault current is interrupted, the auxiliary circuit breaker is opened, and thereby the arc extinguisher is separated from the main circuit and protected. After the recovery of the system, synchronous power application is performed by the high-speed circuit breaker. COPYRIGHT: (C)2003,JPO
