Advantage of the present invention and effect are:
1. to have overcome the refrigeration system volume of existing lithium-bromide solution sorption type refrigerating technology big in the present invention, relates to the many shortcomings of equipment, provides a kind of kind of refrigeration cycle simple, do not comprise the lithium-bromide solution suction type refrigerating technology of any moving equipment.
2. because this refrigeration system volume is little, and there is not any rotating machinery, be highly suitable for vehicle, this class installing space of boats and ships is limited, and exist the occasion of engine exhaust heat to use, and has given full play to the intrinsic advantage that the lithium-bromide solution absorption refrigeration can utilize low-grade heat source.
Description of drawings
Fig. 1 is a refrigeration process flow chart of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
Among the figure: check valve 5, the second generator check valve 6, the first generator check valve 7, first generator 8, the first generator heater 9, the second generator heater 10, second generator 11 that chilled water heat exchanger 1, evaporimeter 2, coil condenser 3, evaporimeter check valve 4, evaporimeter link to each other with generator.
Connect with pipeline between the evaporimeter 2 and first generator 8 and second generator 11, be connected with check valve 5, the second generator check valve 6, the first generator check valve 7 and coil condenser 3 that evaporimeter check valve 4, evaporimeter link to each other with generator on the pipeline.
More than the system that forms by evaporimeter and generator and pipeline, check valve etc. vacuumize.
Be marked with the water that occupies its partial volume in the evaporimeter 2, first generator 8 and second generator 11 are marked with the lithium-bromide solution that occupies its partial volume.Indexs such as the ratio of the water of partial volume or the lithium-bromide solution of partial volume, pressure, vacuum can be with reference to the relevant refrigeration parameters selection of existing absorption lithium bromide refrigerating medium.
Chilled water heat exchanger 1 is arranged in the liquid of evaporimeter 2;
The first generator heater 9 is arranged in the liquid of first generator 8;
The second generator heater 10 is arranged in the liquid of second generator 11.
The first generator heater 9 and the second generator heater 10 alternately heat the lithium-bromide solution in first generator 8 and second generator 11.After liquid in evaporimeter and the generator injected, the water in the evaporimeter 2 is rapid evaporation owing to the existence of lithium-bromide solution in the system.Lithium-bromide solution in the generator comes the water vapor concentration of flash-pot thinning owing to having absorbed.In order to make the water in the evaporimeter 2 constantly evaporate, the lithium-bromide solution that alternately heats in first generator 8 and second generator 11 with the first generator heater 9 and the second generator heater 10 makes its evaporation and concentration.When the lithium-bromide solution in the first generator heater, 9 heating, first generator 8, steam partial pressure in first generator 8 raises, the first generator check valve 7 is opened, steam enters coil condenser 3 by pipeline, enters evaporimeter 2 by the condensed water near environment temperature behind the coil condenser 3; In this course, lithium-bromide solution in second generator 11 has higher concentration, steam partial pressure in second generator 11 is lower than the pressure in the evaporimeter 2, the check valve 5 that evaporimeter links to each other with generator is opened, water evaporation in the evaporimeter 2, steam enters second generator 11 and quilt lithium-bromide solution absorption wherein through check valve 5 and the pipeline that evaporimeter links to each other with generator, lithium-bromide solution concentration decreases simultaneously, when lithium-bromide solution concentration drops to the water that can not effectively evaporate in the generator 2, the second generator heater 10 begins heating, and the first generator heater 9 stops heating.When the lithium-bromide solution in the second generator heater, 10 heating, second generator 11, steam partial pressure in second generator 11 raises, the second generator check valve 6 is opened, steam enters coil condenser 3 by pipeline, enters evaporimeter 2 by the condensed water near environment temperature behind the coil condenser 3; In this course, lithium-bromide solution in first generator 8 has higher concentration, steam partial pressure in first generator 8 is lower than the pressure in the evaporimeter 2, evaporimeter check valve 4 is opened, water evaporation in the evaporimeter 2, steam is through evaporimeter check valve 4 and pipeline enters first generator 8 and quilt lithium-bromide solution wherein absorbs, lithium-bromide solution concentration decreases simultaneously, when lithium-bromide solution concentration drops to the water that can not effectively evaporate in the evaporimeter 2, the first generator heater 9 begins heating, and the second generator heater 10 stops heating.So circulation is gone down, and the water in the evaporimeter 2 is constantly evaporated, and the water evaporation descends its temperature, and chilled water heat exchanger 1 is delivered to conditioned space with cold.
