摘要： PROBLEM TO BE SOLVED: To provide an inexpensive ring or drum made of a fiber reinforced composite material, wherein the damage of fibers at the time of compounding molding is reduced and the control or inclination of a fiber volume ratio is easy. SOLUTION: In the ring made of the fiber reinforced composite material formed by subjecting a preform to compounding molding, the preform has a cylindrical drum and a matrix metal layer formed by spraying a matrix metal on the continuous fibers wound around the outer peripheral part of the cylindrical drum. Since the molten matrix metal is sprayed on the continuous fibers wound around the outer peripheral part of the cylindrical drum, the intertices of the continuous fibers can be filled with the matrix metal at a high density. Therefore, the deformation quantity of the preform at the time of compounding molding can be reduced extremely and the damage of the continuous fibers is prevented to enhance the mechanical strength of the ring made of the composite material.

摘要： PROBLEM TO BE SOLVED: To enhance the performance of a heating tube by providing a plurality of holes, at an interval, on the inner circumferential fringe of a planar fin along the circumferential direction thereof thereby wetting the entire region of the heating tube with a liquid film. SOLUTION: A plurality of holes 7 are made, at an interval, through the inner circumferential fringe of a planar fin 2 along the circumferential direction thereof. When concentrated solution is sprayed from each ejection port 3 of a spray unit 15 disposed above a heating tube 1, liquid drops 4 thereof drip at an interval onto the heating tube 1 and adheres to the outer circumferential surface thereof thus forming a liquid film 5. The heating tube 1 is thereby wetted, over the entire region thereof, by the liquid film 5 through the holes 7 at the root of the fin 2 and heat is exchanged with cooling water passing through the heating tube 1. Consequently, the heating tube 1 is cooled and coolant vapor touching the outer surface of the liquid film 5 is absorbed. Since the heating tube 1 is wetted over the entire region thereof, absorption of coolant vapor and heat exchange of the concentrated solution are increased resulting in the enhancement of performance of an absorption refrigerator.

摘要： PROBLEM TO BE SOLVED: To prevent the undershooting of the cold water outlet temperature when an extremely low load is started and at the same time cool the cold water exit temperature of a high load quickly by providing a temperature sensor for detecting external air temperature and setting a timing for starting a refrigerant pump based on the measurement value. SOLUTION: In an absorption freezer consisting of, for example, a low- pressure reproduction equipment 12, a condenser 13, an absorption equipment 14, a high-temperature heat exchanger 15, and a low-temperature heat exchanger 16, a heat source 1 is thrown to the high-voltage reproduction equipment 2 and a solution pump 3 is driven, thus circulating and condensing a solution 4 and storing a refrigerant 5 in an evaporator 6. In this case, a refrigerant pump 9 is started according to the output of an external air temperature sensor 8. A solution temperature and an external temperature are in a specific relationship, so that the external temperature is considered by a controller 11 and the refrigerant pump 9 is started. Also, when the refrigerant pump 9 is started according to the refrigeration level of the evaporator 6, control is made by a level sensor 10.

摘要： PROBLEM TO BE SOLVED: To prevent flash vapor from flowing into an absorber, and ensure reduction of a load, miniaturization, and making light weight by flash vaporizing part of a liquid refrigerant flowing through an expansion mechanism in a flash tank, and introducing the remaining part into the vaporizer. SOLUTION: A liquid refrigerant on a bottom of a condenser 35 is extracted by a transfer pipe 38 and is drawn by an expansion mechanism 39 to be subjected to adiabatic expansion, and is then supplied into a flash tank 1 where a part thereof is flash vaporized and the remaining part is introduced into an evaporator 10. The refrigerant vapor flash vaporized in the tank 1 passes through a section piping 2 and is fed into a gas chamber 3b of a suction apparatus 3. In contrast, a diluted solution 23 on the bottom in an absorber 14 is extracted by a solution pump 17, and a part thereof is sent to a heat exchanger 7 after passage through a flow rate adjusting valve 6 where it is cooled and is then injected from a nozzle 3e of the suction apparatus 3. Hereby, the refrigerant vapor is fed into an ejector 3d, entraining the refrigerant vapor in the gas chamber 3b and is mixed with the diluted solution and is further sent into the absorber 14.

摘要： PROBLEM TO BE SOLVED: To reduce a cooling heating value per unit suction air quantity by cold water from a refrigerating machine by cooling suction air up to intermediate temperature higher than the fixed temperature of a gas turbine inlet by evaporation of circulating water at a contact part on the upper stream side, and thereafter cooling up to fixed temperature by cold water from the refrigerating machine. SOLUTION: Suction air (the atmosphere) 5 introduced into a suction air duct 1 connected to the inlet of a compressor is directly contacted with circulating water through filler 2a on the upper stream side so as to be cooled up to intermediate temperature higher than the inlet temperature of the compressor. The suction air 5 cooled up to the intermediate temperature is next directly contacted with cold water of very low temperature from a refrigerating machine 3 through filler 2b on the down stream side so as to be cooled up to fixed temperature, and fed to a gas turbine 10. Cold water raised in temperature after cooling the suction air 5 is fed to the refrigerating machine 3 by a pump 8, heat-exchanged with refrigerant so as to become cold water of very low temperature again, and returned to the filler 2b through a cold water pipe 4. Hereby the temperature lowering quantity of the suction air by the cold water from the refrigerating machine can be reduced, and hence the capacity of the refrigerating machine can be reduced.

摘要： PURPOSE: To extend a volume control range of an absorption refrigerator by forming an alcohol storage unit which segments a liquid pool with a submerged weir and installing a supply opening of liquid refrigerant to the upper part and opening a suction opening of liquid refrigerant and alcohol to the lower part. CONSTITUTION: A small area alcohol storage part 21 which segments a liquid pool 11 with a submerged weir 20 is formed. A supply opening 5 of liquid refrigerant including alcohol transferred from a condenser is opened at the upper part of the alcohol storage part 21, and a suction opening is opened on a bottom plate of a housing 10 at the lower part of the alcohol storage part 21. The liquid refrigerant supplied from the supply opening 5 moves to the liquid pool 11 outside the alcohol storage part 21 passing through the lower part of the installing weir 20 but the alcohol floating on the liquid surface of the liquid refrigerant remains in the alcohol storage unit 21. When a circulation pump 4 is started, a large amount of alcohol 2 is sucked up into the suction opening 22 together with the liquid refrigerant and sprayed to a bundle of tubes 13 by way of a pipeline 13.
