Detailed description of the invention
Fig. 1 is a kind of refrigeration system with lithium bromide absorption schematic diagram of wind-light-electricity joint driving of the present invention.
Specific embodiment
Present invention will now be described in further detail with reference to the embodiments and the accompanying drawings, but embodiments of the present invention are unlimited In this.
As shown in Figure 1, the present embodiment includes solar thermal collection system 1, donkey boiler 2, phase transition thermal storage water tank 3, cooling tower 4, cooling water tank 5, generator 6, absorber 7, condenser 8, throttle valve 9, evaporator 10, freezing water tank 11, combined air conditioning box 12, wind heats generator 13;Solar thermal collection system 1, wind heating generator 13, donkey boiler 2 outlet pipeline respectively with phase Become hot water storage tank 3 to connect, the water outlet of phase transition thermal storage water tank 3 by the pipeline of setting pump four respectively with solar thermal collection system 1, Wind heats the entrance connection of generator 13, donkey boiler 2, the pipeline that the hot water outlet of phase transition thermal storage water tank 3 passes through setting pump one It is connect with generator 6, the steam (vapor) outlet of generator 6 connects absorber 7, and absorber 7 is occurred by the piping connection of setting pump two The water outlet of device 6, cooling water tank 5 is successively connected with absorber 7, condenser 8 by the pipeline of setting pump three, and wind heats generator 13 connect with cooling water tank 5, and the outlet of cooling tower 4 is connect with 5 entrance of cooling water tank, and the outlet of cooling water tank 5 passes through setting pump five Pipeline is connect with 4 entrance of cooling tower, and cooling water tank 5 is connected with condenser 8, evaporator 10 outlet respectively with freezing water tank 11, group Box-like air-conditioning box 12 is connected, and freezing water tank 11 is connected with combined air conditioning box 12, and the saturation water out of condenser 8 passes through setting pump 6 and the pipeline of throttle valve 9 be sequentially connected evaporator 10, absorber 7, the pipeline and evaporator that freezing water tank 11 passes through setting pump seven 10 entrances are connected.
The hot water and phase transition thermal storage water tank 3 that solar thermal collection system 1, wind heating generator 13 or donkey boiler 2 generate change Heat, by heat storage in phase transition thermal storage water tank 3;The heat can continuously in heating generator 6 lithium-bromide solution, So that the water evaporation in lithium-bromide solution comes out;After vapor completes refrigerating function, it is brominated lithium suction again in absorber 7 It receives, enters generator 6 later and complete cyclic process;Cooling water tank 5 is connected with absorber 7, condenser 8, after cooling water heat exchange, leads to Supercooling tower 4 rejects heat to environment;The cooling capacity that evaporator 10 generates is stored in freezing water tank 11;Freezing water tank 11 and group Box-like air-conditioning box 12 is connected, and can be used for indoor cooling supply.
