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： 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.

摘要： PROBLEM TO BE SOLVED: To provide an engineering management system ensuring that a maintenance and service person adjusts the operating condition of a product. SOLUTION: A remote supervisory device 4 supervises the operating condition of a product provided at a remote location. A control device 5 controls the remote supervisory device 4 so that condition information 10 showing the operating condition is created and transmitted via an external network 2. The condition information 10 coming from the remote supervisory device 4 is transmitted to an intranet 3. A service support device 8 connects to the intranet 3 and has an error analysis table 26 by which the condition information 10 from the control device 5, error information showing operating errors, and analysis information for solving the errors are associated with one another. A manual 11 for letting a maintenance and service person adjust the operating condition in the event of errors by referencing the error analysis table 26 is created and reported to the maintenance and service person.

摘要： PROBLEM TO BE SOLVED: To provide an absorption refrigerator which prevents debris or metal flakes from flowing into a pump and prevents rocking of the pump from occurring. SOLUTION: A refrigerant R is heated and evaporated by an evaporator 10, directed to an absorber, and absorbed into a solution in the absorber to obtain a thin solution; the thin solution obtained thus is transferred to a generator for pressure rising and superheating to obtain a thick solution of high temperature, which is then returned to the absorber. There are provided a pump P1 for pumping up the refrigerant R or the thin solution from the evaporator 10 or the absorber, and a suction pipe P1A for connecting the evaporator 10 or the absorber with the pump P1. The pipe P1A is made to protrude into the evaporator 10 or the absorber for connection therewith.
