Description of drawings
Comprise that accompanying drawing is for providing the utility model further to be understood, they are included and are constituted the application's a part, and accompanying drawing shows embodiment of the present utility model, and play the effect of explaining the utility model principle with this specification.In the accompanying drawing:
Fig. 1 is the diagrammatic sketch according to the lithium bromide absorption refrigeration and air-conditioning device of vertical two-period form absorption of the present utility model.
Fig. 2 is according to the diagrammatic sketch of arranging the two-period form absorbing structure up and down in the lithium bromide absorption refrigeration and air-conditioning device of vertical two-period form absorption of the present utility model.
The specific embodiment
Now embodiment of the present utility model will be described with reference to the drawings in detail.Fig. 1 is the diagrammatic sketch according to the lithium bromide absorption refrigeration and air-conditioning device of vertical two-period form absorption of the present utility model.As shown in Figure 1, refrigerating plant of the present utility model comprise condenser 1, generator 2, solution heat exchanger 3, on put low temperature absorption device 4, on put cryogenic vaporizer 5, underlying high temperature absorber 6, underlying high-temperature evaporator 7, solution pump or siphon passage 8 (9), absorb evaporation channel 10 (11).Condenser 1 and generator 2 are arranged in the same cavity, and this cavity is arranged at the top of whole refrigerating plant.On put low temperature absorption device 4 and on put cryogenic vaporizer 5 and be arranged in the same cavity, and underlying high temperature absorber 6 and underlying high-temperature evaporator 7 are arranged in the same cavity, these two cavitys are stacked up and down and be positioned at the below of above-mentioned condenser 1 and generator 2 jointly, as being shown specifically among Fig. 2.
The following work of refrigerating plant of the present utility model.Weak solution in the underlying high temperature absorber 6 is carried by solution pump or siphon passage 8 and enter generator 2 after solution heat exchanger 5 is heated up.Concentrate after the heating of weak solution in the generator 2 by the heating thermal source, the condenser 1 that the steam that is produced is set in the same cavity is condensed into water as refrigerant, is stored in the drip tray.Under the effect of gravity and pressure, this water as refrigerant enters underlying high-temperature evaporator 7 after throttling, puts spraying and sprinkling evaporation in evaporimeter 5 and the underlying evaporimeter 7 through water pump or siphon passage 9 last.Because evaporation latent heat is forming lower temperature in the evaporimeter 5 and 7 up and down, and carries out heat exchange with cold water.Simultaneously, the bromize lithium concentrated solution through concentrating enters after solution heat exchanger 3 coolings and puts spray in the low temperature absorption device 4 in the generator 2.On put low temperature absorption device 4 form thus with on put the relatively low pressure of cryogenic vaporizer 5 for steam, make the solution concentration in the same cavity thinning thereby absorb steam by evaporation channel 10, form intermediate concentration solution.This intermediate concentration solution compiles in last bottom of putting low temperature absorption device 4 after the gravity effect, by on the dividing plate hole of putting between absorber 4 and the underlying absorber 5 come together in the spray dish of underlying high temperature absorber 6.This intermediate concentration solution after cooling water heat exchanger heat exchange cooling, sprays and forms the water vapour pressure lower with respect to underlying high-temperature evaporator 7 in underlying absorber 6 under the acting in conjunction of the gravitational difference of absorber up and down and pressure differential.Therefore, above-mentioned intermediate concentration solution is further dilution in underlying absorber 6, forms the weak solution that systemic circulation is used in its bottom.This weak solution is taken out liter through solution pump or siphon passage 8, flows back in the generator 2 after heating by solution heat exchanger 3, thus the circulation of formation solution.
