Abstract: The invention relates to a liquid/gas state separating device capable of separating the molecules of vapour (V) of a liquid evaporating under the effect of a partial vacuum (31) maintained by pumping means from drops (L) of said liquid carried along by the flow of vapour (V), characterised in that it comprises a vapour deflector (50) and a drop collector (60), the vapour deflector (50) imposing at least one sudden change of direction on the flow of vapour (V).

Abstract: A method of controlling the capacity of an absorption chiller by regulating the heat input to a generator in response to a selected one of two system variables. The first variable involves the measured chilled water temperature leaving the system evaporator and the second involves the calculated solution concentration that is being returned to the absorber. Data relating to each variable is sent to a selector where it is processed so that the data can be used to control the heat input to the generator. The temperature data is used to control the heat input during normal chiller operation, however, the selector changes over control to the concentrate related data when the solution concentration level approaches the solution crystallization limit.

Abstract: An absorption refrigerator includes a generator for separating, by vaporization, a refrigerant from an absorption solution, a condenser for liquefying by condensation the vaporized refrigerant, an evaporator for vaporizing the liquefied refrigerant from the condenser by heat exchange with a heat medium, and an absorber for absorbing the vaporized refrigerant to react against the absorption solution to be supplied from the generator. The evaporator has heat exchanger pipes disposed in the vertical direction and refrigerant discharge nozzles for discharging the refrigerant toward the inner walls of the heat exchanger pipes. Each of the refrigerant discharge nozzles is arranged at a position displaced downward by a predetermined distance from the upper end of each of the heat exchanger pipes.

Abstract: A failure diagnosing system for an absorption chiller including an evaporator, absorber, etc. comprises a plurality of sensors for measuring at least one representative temperatures of each of two fluids participating in heat exchange in a specified heat exchange unit, and an arithmetic unit for receiving measurement data from the sensors. The arithmetic unit comprises a circuit for calculating an actual temperature difference using a simple calculation equation defined by a linear expression, a circuit for calculating the amount of heat exchange by the absorber, and a circuit for calculating the degree of abnormality of the absorber by comparing the actual temperature difference with an ideal temperature difference for the same amount of heat exchange as the calculated amount.

Abstract: A refrigeration fluid flow control device for application to absorption refrigeration systems for either cooling or heating air is comprised of an inverted, generally U-shaped, dripper tube having a non-siphon bend which joins on inlet leg and an outlet leg. The inlet leg projects into a refrigeration liquid pool; the outlet leg directs liquid flowed by pumping and surface tension effects, and not by a siphon effect, to the active heat transfer surface of an absorption refrigeration system absorber, evaporator, or desorber assembly.
