Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of air energy high-temperature dehumidification heat pump tobacco leaf drying system with heat sink as shown in Figure 1, comprise and to be arranged in apparatus casing by air channel and baking room UNICOM internal circulation heat-exchanging device 2, compressor 1, external circulation heat exchanger 5, main electric expansion valve 7, to spray electric expansion valve 6 and gas-liquid separator 8, described device is interconnected by pipeline 10.Cross valve 4 and changement 9 is connected with between internal circulation heat-exchanging device 2 and external circulation heat exchanger 5; Cross valve 4 also has gas-liquid separator 8 in succession; Compressor 1 is connected with described internal circulation heat-exchanging device 2 by pipeline 10 one end, and the other end is connected with described gas-liquid separator 8; Main electric expansion valve 7 is arranged on the pipeline between changement 9 and gas-liquid separator 8, and spray electric expansion valve 6 one end and be arranged between main electric expansion valve 7 and gas-liquid separator 8, the other end is arranged between cross valve 4 and gas-liquid separator 8; Pipeline 10 between compressor 1 and cross valve 4 is connected with control valve 3.Internal circulation heat-exchanging device 2 comprises Inner eycle blower fan 21 and is arranged on interior heat exchanger 23 and the supplementary heat exchanger 22 of this Inner eycle blower fan side.External circulation heat exchanger 5 comprises outer circulation blower fan 51 and is arranged on the external heat exchanger 52 of this outer circulation blower fan side.Gas-liquid separator 8 is the gas-liquid separator with regenerative apparatus.
The course of work of the present utility model is: be divided into heating mode, dehumidification mode and cooling mode.In a heating mode, by the work of compressor 1, the gas of refrigerant boil down to HTHP enters the interior heat exchanger 23 in internal circulation heat-exchanging device 2, supplementary heat exchanger 22 is entered through cross valve 4, after rejecting heat to baking room by Inner eycle blower fan 21 and air channel, refrigerant condensation becomes the liquid of HTHP, through changement 9, enter the gas-liquid separator 8 with regenerative apparatus, heat exchange further with low temperature return-air, improve degree of supercooling, enter the liquid refrigerants that the throttling of main electric expansion valve 7 becomes low-temp low-pressure afterwards, enter external heat exchanger 52 again to evaporate, the gas of low-temp low-pressure is become by the heat in the effect absorbing environmental air of outer circulation blower fan 51, enter the gas-liquid separator 8 with regenerative apparatus, compressor 1 is got back to after the further heat exchange of condensed high-temperature liquid state refrigerant, complete a circulation.Along with circulation is constantly carried out, the heat in surrounding air is just continually to being discharged in baking room, and realize drying effect, not only efficiency utilization rate is high, also significantly shortens baking time, improve and dry efficiency, and dries quantity is good.
Under dehumidification mode, by the work of compressor 1, the gas of refrigerant boil down to HTHP enters interior heat exchanger 23, external heat exchanger 52 is entered through cross valve 4, refrigerant condensation becomes the liquid of HTHP, enter the gas-liquid separator 8 with regenerative apparatus, heat exchange further with low temperature return-air, improve degree of supercooling, enter the liquid refrigerants that the throttling of main electric expansion valve 7 becomes low-temp low-pressure afterwards, then enter supplementary heat exchanger 22 to evaporate, enter the gas-liquid separator 8 with regenerative apparatus again, compressor 1 is got back to after the further heat exchange of condensed high-temperature liquid state refrigerant, complete a circulation.Because supplementary heat exchanger 22 surface temperature is lower than the dew-point temperature of air in baking room, hot and humid air in baking room is lowered the temperature after supplementary heat exchanger 22, steam wherein becomes water to discharge in supplementary heat exchanger 22 surface condensation, and the heat of the release of steam condensation is simultaneously absorbed along with kind of refrigeration cycle is discharged in baking room at interior heat exchanger 23 place by refrigerant again.
Under cooling mode, by the work of compressor 1, the gas of refrigerant boil down to HTHP is through control valve 3, external heat exchanger 52 is entered through cross valve 4, refrigerant condensation becomes the liquid of HTHP, enter the gas-liquid separator 8 with regenerative apparatus, heat exchange further with low temperature return-air, improve degree of supercooling, enter the liquid refrigerants that the throttling of main electric expansion valve 7 becomes low-temp low-pressure afterwards, then enter supplementary heat exchanger 22 to evaporate, enter the gas-liquid separator 8 with regenerative apparatus again, compressor 1 is got back to after the further heat exchange of condensed high-temperature liquid state refrigerant, complete a circulation.Because supplementary heat exchanger 22 surface temperature is lower than the dew-point temperature of air in baking room, the hot and humid air in baking room is lowered the temperature after supplementary heat exchanger 22, and simultaneously steam wherein becomes water to discharge in supplementary heat exchanger 22 surface condensation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
