Described first generator 5, second generator 6, first condenser 21, second condenser 22 are finned heat exchanger.
The present invention adopts the LiBr aqueous solution and R410A (or R22 or alternative refrigerant) to be illustrated.
Because there is stronger corrosivity in the lithium bromide system, so all adopt copper or stainless steel structure in the part of lithium bromide contact.Generator adopts the pouring form of dripping, and promptly weak solution drops in the nest plate type heat exchanger surface by dripping the pouring structure, causes the refrigerant vapour that the generator centre takes place to produce to be difficult to evaporate with regard to being easy to like this.In order to solve this contradiction, improve the heat and mass efficient of generator, we are divided into two parts up and down with the nest plate type generator, and structure is shown in " low-grade energy drives and the mechanical power driven composite refrigeration system high pressure module structure chart ".
When system moves, press schematic diagram and in generator and condenser, feed heat source water and cooling water respectively, dripping and drenching structure is a stainless steel square box, high about 2cm, size dimension and generator floor space suitable (150 * 150mm).Be equipped with the aperture that diameter is Φ 2mm in the bottom of dripping the pouring square box every 1cm, weak solution flows down by aperture, the hot water heat exchange that drips in generator surface and the generator takes place, the refrigerant vapour that takes place to produce upwards moves along the space around the generator, run into behind the condenser with condenser in the cooling water heat exchange, thereby be condensed into liquid refrigerant, liquid refrigerant is pooled in the drip tray below the condenser by pipeline through the throttle mechanism inflow evaporator.The weak solution of drip drenching flows to the generator bottom after generating process carries out, flowing through by pipeline enters absorber behind solution heat exchanger and the throttle mechanism.
The heat exchange caliber of nest plate tube type generator is external diameter 9.52mm, single row of tubes spacing 17.6mm, and spacing of fin is 1.7mm, and fin thickness 0.14mm, pipe arrange to put and adopt difference row form, and fin two end-stopping plates adopt stainless steel material, to improve the corrosion resistance of heat exchanger.In order to obtain rational water flow velocity, generator is made as two heat exchanger parallel connections, and promptly the flow process number in the generator is 2.Spread pattern is: two heat exchanger parallel connections up and down, and the total pipe range 2.5m of single heat exchanger, single heat exchanger structure form is 3 rows, 6 row, heat exchange unit single process length is 0.14m.
Structure of condenser and generator are similar, also adopt the nest plate tubular structure.Cooling water flows in pipe, and refrigerant vapour and cooling water heat exchange are at out-tubular condensing.
Shown in " low-grade energy drives and the mechanical power driven composite refrigeration system high pressure module structure chart ", condenser and generator coexist in " high pressure " container, the high pressure here is meant the high-pressure section of lithium bromide absorption refrigeration system, and the saturation pressure during condensation just is about 7kPa.Because the specific volume of steam is very big under the condition of low pressure, for the resistance that reduces system then will become very thick by the refrigerant vapour pipeline that generator flows to condenser, so for convenience's sake, usually generator and condenser are placed on (sealing side's bucket as shown in the figure) in the container.Refrigerant vapour rises to condenser from the heat exchanger periphery, is condensed into refrigerant liquid with the condenser heat exchange, and liquid collects in the drip tray and drawn by pipeline.
The machined parameters and the generator of condenser are similar, and the heat transfer caliber of nest plate pipe still is 9.52mm, and other specifications parameters are identical with generator.In order to be consistent with the generator floor space, condenser also should be 6 row, and the version of single heat exchanger is 3 rows, 6 row.Because the restriction of cooling water flow and cooling water flow velocity, the parallel transistor row number in the condenser is 6, and two heat exchangers are all made the form of 6 comb parallel connections up and down for convenience's sake, and two heat exchangers are taked cascaded structure up and down.
