Solar lithium bromide units of solar air conditioning patents seek cooperation

① system was evacuated and add lithium bromide solution. With the same conventional double effect absorption refrigeration unit. ② Select the initial boot fine weather. Start-up procedures and the traditional double effect absorption refrigeration unit is basically the same, except that the driving heat source part, heat the steam control valve 28 is not open, open it only when the auxiliary heat source in the system need to start. But the sun tracking system to work, the focus point of the sun's image focused on high-temperature solar thermal happen straight pipe 14 to provide sufficient heat as a driving source. To maximize the use of solar radiation, confocal imaging point Daylight sun tracking system will always focus on high-temperature solar thermal happen straight pipe 14 to provide driving heat source, the system will be adjusted by an energy storage system unit load, to match the solar radiation the amount of change, the system can still operate smoothly adapt to natural changes in the driving heat source was the case. ③ process system operating under normal conditions. Absorber and a dilute solution in the absorption liquid storage tank 55, transmission fluid pump 9 in three columns by the generator to direct solar heated hot tube 14 occurs, the high temperature generator 5 and the low-temperature generator 4, the first flow of the second solvent The solar valve 12 occurs directly heated hot temperature of the tube 14 is adjusted so that the opening of direct thermal effluent concentration of high-temperature solar energy generating tube was relatively constant, a dilute solution of high temperature heat exchanger 6, the second solvent flow valve 212, dilute lithium bromide solution shunt tube 15 into the high-temperature solar direct thermal generating tube 14. Due to the high temperature solar direct thermal generating tube 14 is focused on the solar energy heating the interior of a dilute solution into the rapid heating, since the system in a vacuum, dilute solution begins to flow by gravity in the course of a concentrated solution of lithium bromide manifold 17 boiling, high temperature refrigerant vapor refrigerant vapor up into the manifold 16, while dilute lithium bromide solution was concentrated flow into a concentrated solution flows into the manifold after 17 Summary 18 liquid gas separator. The refrigerant vapor into the manifold temperature refrigerant vapor through the summary and then the system via line 16 into the refrigerant vapor heat exchange tubes within a cluster of 54 high-temperature generator 5, to cool high-temperature refrigerant vapor condenses pressure release heat After the coolant water into the condensate separator 47, the other part of the refrigerant vapor pressure after cooling by steam injection device 57 and the high-temperature generator 5 mixed refrigerant vapor into the low temperature generator 4 clusters. 5 is a dilute solution of high temperature generator heating heat absorption, while the steam injection apparatus 57 due to the action of a low pressure state so that the high-temperature generator 5, a dilute solution thus within the high temperature generator 5 will be produced at a lower temperature boiling refrigerant Steam and dilute solution is concentrated. The third solution flow regulating valve 13 regulating the temperature of the high temperature generator 5 based on the opening degree, the control amount of the dilute solution flowing into the high-temperature generator 5, to maintain the concentration of high-temperature generator effluent solution 5 is relatively constant. 4 refrigerant vapor entering into the low temperature generator refrigerant condenses into water and heat into the condenser 3. 4 within the low temperature generator dilute solution is heated to produce a low temperature refrigerant vapor directly into the condenser 3 is cooled refrigerant is condensed into water. At the same time within a dilute solution of low-temperature generator 4 is concentrated. Solution flow rate adjusting valve 129 regulating the opening degree of the low temperature generator 4 according to the temperature, controlling the amount of the dilute solution flowing into the low temperature generator 4, so that the concentration of the solution flowing out of the low temperature generator 4 is relatively constant. Condensed refrigerant entering the separator 47 by the water coolant water separating device 46, the refrigerant flow switching valve 21 into the condenser 3 is further cooled by the cooling water into the low temperature generator 4 confluence. The condenser 3 in the collection of heat is flowing through the cooling water condenser 3 within the cluster away, to exclude external cooling system. After the condenser 3 summarizes each generator refrigerant water enters the evaporator 2 through closure. The liquid gas separator 18 out of the concentrated solution and high temperature generator 5 after mixing the concentrated solution flowing into the high temperature heat exchanger 6 with a dilute solution of heat generator infusion pump 9 pumped into the concentrated solution after cooling the storage tank 53, while the low temperature generator 4 concentrated solution flowing into the low-temperature heat exchanger 7 with a dilute solution of infusion pump generator 9 are pumped into the concentrated solution after cooling storage tank 53. Concentrated solutions of the generator out of the concentrated solution storage tank after 53 summary, and then with a dilute solution of the system via line 31 into the valve regulating the flow rate by the fourth solution mixed intermediate concentration solution, and then by absorbing liquid supply pump 20 to draw a mixed solution, Enter the sprinkler system, spraying a cluster outside the absorber surface, absorb 2 of evaporated refrigerant vapor from the evaporator, the heat released is absorbed by the cooling water is taken within a cluster, excluding external cooling system. The solution was diluted into a dilute solution enters the next cycle again. Meanwhile coolant pump 10 to draw 2 refrigerant coolant water inside the water storage tank 56 of the evaporator and, delivered to the sprinkler system, spraying in two clusters outside surface evaporator, since the water vapor in the absorber 1 is absorbed by the liquid absorbing a low pressure state, the refrigerant in the evaporator 2 water-cluster surface evaporation of water vapor into the absorber 1, while chilled water heat evaporator 2 water vapor within the cluster have been taken away by the energy storage system and air conditioners the heat of chilled water circulating chilled water circuit and the like within the pump into the cooling system. Absorption by water vapor in the absorber liquid 1 into a dilute solution of the next cycle. Such dilute solution infusion pump continuously transported by the generator 9 in three columns to the solar direct thermal generating tube 14 temperature, high temperature and low temperature generator 4 generator 5, producing refrigerant vapor into the refrigerant and water, dilute solution was concentrated the concentrated solution, and then flows back to the evaporator 2 and the absorber dilute solution diluted to 1 again, the cycle of the loop. While chilled water continues to flow through the evaporator 2 release heat when the heat absorbed by the refrigerant water evaporates, the temperature dropped to obtain a steady stream of freezing water into storage and user end portion of frozen water circuit of the air conditioner to meet the needs of users with cold . After absorber 1 and the condenser 3 absorption system exhaust heat in the cooling water, hot water flowing through the cooling season discharging part of the heat exchanger unit 22, after cooling loop into the cooling system. Absorbs heat and store hot water in the cooling season provides cheap sanitary hot water for the user. Because of the volatility of the great amount of solar radiation, the system through a concentrated solution storage tank 53, the refrigerant water storage tank 56 and absorbing liquid storage tank 55 to adjust the amount of solar radiation fluctuations in the system, when solar radiation is greater than the system operating at full capacity When the required driving heat, the system concentrated solution and refrigerant water excess heat output are stored in a concentrated solution storage tank 53 and the coolant water storage tank 56, in the amount of solar radiation and then drop into the refrigeration cycle system, enter each regenerator dilute solution produced is stored in a 55-absorbing liquid storage tank, solar radiation rose again to more than drive the heat required for the system operating at full capacity when the re-absorption of excess heat generated refrigerant water stored in the refrigerant inside water storage tank 56, dilute solution was concentrated stored in concentrated solution storage tank 53, and so on, to make the system running smoothly. At the same time cold cold system users need not be synchronized generated, the system through a hierarchical storage tanks 36, a host of water circulating pump 41 and the air conditioner water circulating pump 42 to adjust the system cooling capacity and cooling capacity required by the user balance between flow and cooling capacity of water circulating pump 41 provides a host of synchronous, air-conditioner water circulation pump 42 provides flow and cooling capacity required by the user synchronization, when the refrigeration system is greater than the amount you need to cool, the host water cycle flow pump provides more than 41 air conditioner water circulation pump 42 provides a flow of cold water outlet unit 24 out of the freezing water by the air-conditioner water circulation pump portion 42 and into the user end of the air conditioner circulating flow of water circulating pump 41 back to the host, some by lower storage tank inlet and outlet 37 into the stratified storage tank 36, while the higher layer storage tank top temperature of 36 chilled water inlet and outlet from the tank 38 is high top out, but also a host of water flowing into the circulating pump 41 and the end user chilled water circulating back into the air conditioner and then mixed with cold water via the inlet unit 23 enters the next cycle. Such excess freezing water was stored in a stratified storage tank 36. When the system cooling capacity is less than the cooling capacity required by the user, the flow of water circulating pump 41 provides a host of smaller than the flow of water circulating pump 42 to provide an air conditioner, and the air conditioner water circulation pump 42 via the user end of the air conditioner out of the chilled water circulating through the host part Water circulating pump 41 into the refrigeration cycle, the excess part of the upper inlet and outlet through the tank 38 into the stratified storage tank 36, while the bottom 36 stratified storage tank water from freezing and out of the cold water storage tank lower outlet nozzle 37 and by the outflow unit 24 out of the freezing water mixed into the air-conditioner water circulation pump 42, the next time the user end of the air conditioner cycling, so cold store in stratified storage tank 36 within the end user will enter the air conditioner cycling. So that the cooling capacity of the system and the user to establish a balance between the required cooling capacity. ④ system operating procedure is insufficient sunshine. Specifically divided into two cases, one is almost no sunshine and humid weather or sunlight intensity can not fully meet the cooling needs of the night; one is the intensity of sunshine can not fully meet the cooling requirements of the hot weather. In the former case the solar collector system to stop working, the second solution flow control valve 12 is closed, heat the steam control valve 28 is activated, the system completely using auxiliary heat source cooling, specifically the cooling process and the same conventional double effect absorption refrigeration unit. During operation the second case with the full use of solar-powered cooling system is basically the same, except that the system starts an auxiliary heat source for the high temperature steam heating generator 5, and adjust the heat steam control valve 28 is opened according to the system chilled water outlet temperature degree, control the amount of fluid entering the high-temperature heat steam generator 5 in order to maintain the high-temperature generator effluent solution flow rate 5 of the system cooling capacity balance. After the auxiliary heat source vapor into the high-temperature heat generator 5 condenses into water, dilute solution within the high temperature generator 5 provides an auxiliary heat source to boil. Because of the high temperature heat generator 5 to obtain an auxiliary steam source provided such that the refrigerant vapor flowing through the heat exchange tubes 54 of the cluster refrigerant vapor condenses into only a small portion of the refrigerant condensed water enters into the separator 47, and most refrigerant vapor then enters the steam injection means 57 in order to maintain a low pressure within the high temperature generator 5. The outflow temperature generator vapor condensate auxiliary heat source 5 proceeds to the heat recovery unit 8 with a dilute solution of heat flow low temperature generator 4, after cooling is discharged outside of the refrigeration system. ⑤ uncooled season preparation of sanitary hot water unit during operation. Absorber 1 and absorbing liquid storage tank 55 of a dilute solution, conveyed by the solar generator infusion pump 9 to a high temperature direct thermal generating tube 14, due to the high temperature solar direct thermal generating tube 14 is focused on the solar heating dilute solution into the interior of rapid heating, since the system is in a vacuum, a dilute solution by gravity flow during a concentrated solution of lithium bromide manifold 17 begins to boil, generating high-temperature refrigerant vapor up into the refrigerant vapor manifold 16, while dilute lithium bromide solution was concentrated flow into a concentrated solution flows into the manifold after 17 Summary 18 liquid gas separator. The refrigerant vapor into the manifold temperature refrigerant vapor through the system via line 16 and then aggregated into the condensate separator 47 and flowing through the sanitary hot water heat exchanger season uncooled device 19 condenses sanitary hot water heat exchanger to cool the cold Water, and then the coolant water separation device 46, the refrigerant flow switching valve 21 into the absorbing liquid storage tank 55 into the absorber mixing a concentrated solution of 1 next cycle, the refrigerant flows through the non-season hot water heat exchanger device sanitary hot water 19 refrigerant vapor condensation heat absorption and storage. Uncooled season provides cheap sanitary hot water for the user. At the same time concentrated liquid solution gas separation device 18 is high temperature heat exchanger 6, the concentrated solution storage tank 53 back into the absorber 1, and back into the water to absorb the refrigerant liquid storage tank 55 is mixed into the next cycle, and so forth, Uncooled season flowing through sanitary hot water heat exchanger means to provide heat and hot water 19 to store the main heat in uncooled season provides cheap sanitary hot water for the user. That is, the system through the double effect absorption chiller cooling process improvement and with having a high temperature solar collector system generator functions, resulting in a higher thermal coefficient COP≈1.7 three-effect absorption chiller The four seasons while also uninterrupted supply of sanitary hot water, due to the higher coefficient of thermal systems to obtain the necessary heat units less cold, and because the effective range of the solar heat collector expand 80 ℃ -160 ℃, its collector efficiency has been greatly improved by the collector to produce relatively above 150 ℃ steam. Coupled with uninterrupted supply of hot water can Seasons because of the high energy efficiency of refrigeration systems, so collector area is relatively small, only Gu winter supply of sanitary hot water use, matching the season better, more efficient use. Making it more cost-effective. At the same time the entire system in a vacuum operation, the security better and longer system life.
