Description
[technical field]
The present invention relates to a kind of vehicle-mounted refrigerating plant, more particularly, relate to a kind of generator of vehicle-mounted refrigerating plant.
[background technology]
Existing motorbus adopts LiBr-Air-conditioner to freeze usually, and LiBr-Air-conditioner generally includes absorber, generator, condenser, evaporimeter four parts, and its absorber adopts water-cooling pattern to dispel the heat usually, therefore needs in addition a cover water circulation system.Its operation principle is: boost through solution heat exchanger from absorber bromize lithium dilute solution out, after being improved by generator high temperature concentrated solution heating-up temperature out, enter generator.Be subject to the heating of external heat source in generator, solution temperature improves until boiling, and the moisture content in the solution is evaporated gradually, and solution concentration constantly increases.The water as refrigerant steam that is evaporated in the generator enters condenser, passes into cooling water in the heat-transfer pipe of condenser, and the water cooling so the outer water as refrigerant steam of pipe is cooled is condensed into water, and this is water as refrigerant.The water as refrigerant that accumulates in condenser flows in the evaporimeter after throttling, because the pressure in the pressure ratio evaporimeter in the condenser wants high, after water as refrigerant enters evaporimeter, because pressure decreased at first flashes off part water as refrigerant steam.Because evaporimeter is spray type heat exchanger, spray quinoline amount is than the large manyfold of evaporation capacity, so most of water as refrigerant is to be gathered in the water pond of evaporimeter, then send in the shower of evaporimeter after being boosted by refrigerant pump, spray on the tube bundle outer surface through nozzle, after having drawn the heat that flows through the chilled water in the pipe, flash to the water as refrigerant steam of low pressure.Because the evaporimeter internal pressure is lower, so can obtain production process or the needed low temperature chilled water of air-conditioning system, reaches the purpose of refrigeration.The refrigerant vapour that is evaporated enters absorber, and the intermediate solution of being sent here by absorber and evenly spraying absorbing the tube bundle appearance is absorbed, and solution is again thinning.Intermediate solution is by being mixed to get from the concentrated solution after the solution heat exchanger heat release cooling and the weak solution in the absorber liquid capsule.For guaranteeing constantly carrying out of absorption process, need absorption process institute liberated heat is in time discharged.Intermediate solution becomes weak solution after having absorbed a certain amount of steam, is gathered in the absorber bottom liquid capsule, delivers to generator by generator pump again, and so circulation endlessly.
As shown in Figure 1, usually adopt the structure of immersion at the generator 10 of above-mentioned lithium bromide water absorption refrigerating plant, namely in enclosed container 1, be set to suitable negative pressure, provide the heat exchanger 2 of heat in container 1 interior setting by external heat source 20, heat exchanger is immersed in the lithium-bromide solution 3; Heat by 2 pairs of lithium-bromide solutions 3 of heat exchanger, so that the evaporation of the water as refrigerant in the lithium-bromide solution 3 forms refrigerant vapour 4, refrigerant vapour 4 obtains water as refrigerant 5 after condenser 30 heat exchanges, water as refrigerant 5 forms refrigerant vapour in evaporimeter with after the surrounding air heat exchange, and with the surrounding air cooling, reach the purpose of refrigeration.Forming weak solution after the top layer formation bromize lithium concentrated solution of lithium-bromide solution absorbs in overfall 5 is expelled to absorber 40 and with refrigerant vapour again can be to generator 10 by pump.In this generator, because the proportion of lithium-bromide solution is very large, so that the pressure of lithium-bromide solution bottom is greater than the pressure on lithium-bromide solution top layer, namely there is larger liquid level pressure reduction, then the boiling point of bottom solution wants high, the temperature drift of the refrigerant vapour that forms of bottom lithium-bromide solution then, and then hindered the cryogen evaporation of water, have influence on refrigeration.
In addition, because what generator adopted is the immersion structure, the heat exchanger tube of heat exchanger needs enough areas could obtain higher heat exchange efficiency, and this has just determined the interior heat exchanger tube of generator or be set to multilayer, or has been set to all heat exchanger tubes in the structure of same layer.But the lithium-bromide solution of the higher liquid level of the structure of Multi-layer exchanging heat pipe needs could be with its submergence, so that liquid level pressure reduction further increases; Although and the structure of individual layer heat exchanger tube can reduce liquid level, need larger area, this is subject to larger restriction for the car body of limited space.
In addition, in generator, the bromize lithium dilute solution of importing be concentrated after bromize lithium concentrated solution be blended directly in the generation cavity so that the lithium-bromide solution concentration that derives from overfall is lower, thereby so that the absorption efficiency in the absorber reduce.
