Abstract
The utility model discloses a lithium bromide absorbing refrigerator, which relates to a refrigerating device, particularly the refrigerator in which the upper parts of a generator and a generator with low pressure are provided with a crystallization preventing device. The utility model mainly comprises the generator, a heating device, the generator with low pressure, a condenser, an evaporator, and an absorber. A solution storing box on a high position with crystallization preventing function is positioned upon the generator and the generator with low pressure. When the refrigerator is in a sudden fault, refrigerant water positioned inside the solution storing box can automatically diluting the lithium bromide solution.
Description
The utility model relates to refrigeration plant, refers in particular to a kind of refrigeration machine that anti-crystallization device is set at generator and above the low pressure generator.
Lithium-bromide absorption-type refrigerating machine is a power with the water vapour usually, is cold-producing medium with water, is absorbent with the lithium-bromide solution.During work, the effect of absorbent is to absorb the refrigerant vapour of flash-pot, to reduce water saturation vapour pressure in the evaporimeter, guarantees that evaporimeter normally moves.The effect of refrigerant is to absorb the heat of chilled water, to produce cold effect.Absorbent is after having absorbed moisture content, and concentration is thinning, and absorbability begins to descend, and therefore, needs to heat with high-temperature water vapor, so that the water evaporation in the absorbent is separated out, becomes concentrated solution, then, absorbs water vapour for absorber again.
Lithium bromide belongs to salt; equally with salt can crystallization separate out under certain condition; when refrigeration machine normally moves; in case catastrophic failure occurs, during phenomenons such as shutdown suddenly, just might cause the lithium bromide crystallization to be separated out; can influence the proper flow of lithium-bromide solution attached to the lithium bromide crystal on the duct wall; when serious, even the meeting blocking pipe, refrigeration machine can not be moved.
The purpose of this utility model is that design a kind ofly can in time be diluted lithium-bromide solution when catastrophic failure, in case the refrigeration machine of crystallization.
Its main technical schemes is that this refrigeration machine mainly comprises generator (5), heater (11), low pressure generator (21), condenser (23), evaporimeter (17) and absorber (16), liquid reserve tank (26) is set at generator (5) and above the low pressure generator (21), and, the water as refrigerant inlet tube (27) of liquid reserve tank (26) is connected with refrigerant pump (37), outlet (25) utilizes valve (29) respectively, (24) and cryogen water pipe (30), (7) with low pressure generator (21), the bottom of high pressure generator (5) connects, the overflow pipe (28) that is connected with evaporimeter (17) in addition on liquid reserve tank (26) top.
The utility model has the advantages that owing to be provided with high-order water as refrigerant liquid-storing box, when refrigeration machine turns round, utilize the effect storage water as refrigerant of refrigerant pump, make refrigeration machine in the running, the concentration of lithium-bromide solution remains the best, in addition, when operation the time is broken down suddenly or had a power failure and can't normally dilute the time, the water as refrigerant in the high-order liquid-storing box is back to the denseer position of solution concentration in the unit automatically under the gravity effect, automatically the dense lithium-bromide solution of dilution is separated out to avoid the lithium bromide crystallization.
