Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
Example 1:
as shown in fig. 2, the unit is a hot water vapor double-effect two-stage lithium bromide absorption chiller composed of a high-pressure generator 26, a high-temperature hot water generator 12, a low-pressure generator 30, a low-temperature hot water generator 11, a high-temperature condenser 13, a low-temperature condenser 9, a high-temperature evaporator 3, a low-temperature evaporator 22, a high-temperature absorber 21, a low-temperature absorber 2, a high-temperature heat exchanger 18, a low-temperature heat exchanger 6, a heat recoverer 31, a condensate heat exchanger 16, a high-temperature solution pump 24, a low-temperature solution pump 25, a high-temperature refrigerant pump 23, a low-temperature refrigerant pump 1, a generating pump 29, and pipelines and valves connecting the components. The low-temperature hot water generator 12 and the low-temperature hot water generator 11 are collectively called a hot water generator; the high-temperature condenser 13 and the low-temperature condenser 9 are collectively called a condenser; the high temperature evaporator 3 and the low temperature evaporator 22 are collectively referred to as an evaporator; the high temperature absorber 21 and the low temperature absorber 2 are collectively referred to as an absorber. The high temperature solution pump 24 and the low temperature solution pump 25 are collectively referred to as a solution pump; the high temperature coolant pump 23 and the low temperature coolant pump 25 are collectively referred to as coolant pumps. Wherein, the low-pressure generator 30 is arranged at the lower part of the high-temperature hot water generator 12 and forms a composite high-temperature generator condenser with the high-temperature condenser 13, the low-temperature generator 30 and the low-temperature condenser 9 form a low-temperature generator condenser, the composite high-temperature generator condenser and the tube bundles of the low-temperature generator condenser are arranged in the same generator condenser cylinder 27, and the middle is separated by a baffle plate 33. The tube bundles of the four parts of the high temperature absorber 21, the low temperature evaporator 22, the high temperature evaporator 3 and the low temperature absorber 2 are arranged in the same evaporation absorber cylinder 28, and the middle part is completely separated by a segmented baffle plate 32 to form a two-stage structure of a high temperature stage and a low temperature stage. The solution lines of the low-temperature hot water generator 11 and the high-pressure generator 26 are provided with a generating pump 29 and a heat recovery device 31. A condensate heat exchanger 16 is arranged on the solution pipeline from the low-temperature heat exchanger 6 to the low-temperature water generator 11.
The unit uses hot water and steam to perform refrigeration operation. And (3) circulating the solution at the high temperature section: high temperature absorber 21→high temperature solution pump 24→high temperature heat exchanger 18→high temperature water generator 12→low pressure generator 30→high temperature heat exchanger 18→high temperature absorber 21; low temperature Duan Rongye cycle: low temperature absorber 2- & gt low temperature solution pump 25- & gt low temperature heat exchanger 6- & gt condensate heat exchanger 16- & gt low temperature water generator 11- & gt generator pump 29- & gt heat recoverer 31- & gt high pressure generator 26- & gt heat recoverer 31- & gt low temperature water generator 11- & gt low temperature heat exchanger 6- & gt low temperature absorber 2. Hot water from an external system enters the high-temperature hot water generator 12 and the low-temperature hot water generator 11 in series through the hot water inlet pipe 15 and flows out through the hot water outlet 8 pipe. Cold water from an external system enters the high-temperature evaporator 3 and the low-temperature evaporator 22 in series through the cold water inlet pipe 4 and then flows out through the cold water outlet pipe 20; cooling water from an external system enters the absorber (the low-temperature absorber 2 and the high-temperature absorber 21 in parallel) and the condenser (the low-temperature condenser 9 and the high-temperature condenser 13 in parallel) in series through the cooling water inlet pipe 5, and then flows out through the cooling water outlet pipe 19. Working steam from the outside enters the high-pressure generator 26 through the steam inlet pipe 7 to heat the solution in the cylinder, steam condensate enters the condensate heat exchanger 16 to exchange heat with the solution from the low-temperature heat exchanger 6 for cooling, and the cooled steam condensate is discharged out of the machine or recycled through the condensate outlet pipe 17. The refrigerant vapor generated by the high-pressure generator 26 enters the low-pressure generator 30 through the refrigerant vapor pipe 34 to heat the solution in the high-temperature section, and the formed refrigerant vapor condensate enters the low-temperature condenser 9 through the refrigerant vapor condensate pipe 35. Because the heat of the working steam is utilized twice in the high-pressure generator 26 and the low-pressure generator 30, double-effect refrigeration cycle is realized, thereby reducing the refrigeration energy consumption of the unit and improving the comprehensive efficiency of the unit.
When the unit is operated by hot water alone, the high-pressure generator 26, the low-pressure generator 30, the condensate heat exchanger 16 and the heat recoverer 31 do not operate. The hot water generator 11, condenser, evaporator and absorber of the unit respectively circulate the solution and the refrigerant water according to the high temperature section and the low temperature section, the generating pump 29 stops running, and the condensate heat exchanger 16 is only a circulation channel of the low temperature dilute solution. The hot water, cold water and cooling water system flow from the external system is the same as the above-mentioned refrigerating operation using both hot water and steam.
When the unit is operated by using steam alone, the high-temperature hot water generator 12 and the low-temperature hot water generator 11 do not work. And (3) circulating the solution at the high temperature section: high temperature absorber 21→high temperature solution pump 24→high temperature heat exchanger 18→high temperature hot water generator 12 (not in operation) →low pressure generator 30→high temperature heat exchanger 18→high temperature absorber 21; low temperature Duan Rongye cycle: low temperature absorber 2→low temperature solution pump 25→low temperature heat exchanger 6→condensate heat exchanger 16→low temperature water generator 11 (not in operation) →generation pump 29→heat recoverer 31→high pressure generator 26→heat recoverer 31→low temperature water generator 11→low temperature heat exchanger 6→low temperature absorber 2. Working steam, cold water and cooling water from an external system flow is the same as that when hot water and steam are used for refrigeration operation.
Example 2:
the cooling water system in the unit absorber and the condenser can be in series flow as shown in figure 2 or in parallel flow as shown in figure 3. And cooling water is in two paths, one path of cooling water is connected in series to enter the low-temperature absorber and the high-temperature absorber, the other path of cooling water is connected in series to enter the low-temperature condenser and the high-temperature condenser, and the two paths of cooling water are combined and then flow out through the cooling water outlet pipe. The parallel flow can reduce the temperature of the hot water backwater to , and the utilization rate of the hot water is improved.
