Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the one band dehumidification function high temperature air energy heat pump drying system that the present embodiment provides, it comprises compressor 1, internal circulation heat-exchanging device 2, supplementary heat exchanger 3, external circulation heat exchanger 4, changement 5, expansion valve 6, gas-liquid separator 7 and cross valve 8, described internal circulation heat-exchanging device 2 is arranged on outside baking room 9, and be connected with baking room 9 by thermal insulation air channel, described supplementary heat exchanger 3 is arranged on this internal circulation heat-exchanging device 2, described cross valve 8 by pipeline 10 respectively with described internal circulation heat-exchanging device 2, supplementary heat exchanger 3, gas-liquid separator 7 is connected with external circulation heat exchanger 4, described changement 5 respectively with described supplementary heat exchanger 3, gas-liquid separator 7 is connected with external circulation heat exchanger 4, described compressor 1 is connected with gas-liquid separator 7 with described internal circulation heat-exchanging device 2 by pipeline 10, described expansion valve 6 is arranged on the pipeline 10 between described changement 5 and gas-liquid separator 7.
Described gas-liquid separator 7 is the gas-liquid separator with regenerative apparatus.Described internal circulation heat-exchanging device 2 comprises interior circulating fan 21 and is arranged on the interior heat exchanger 22 of these interior circulating fan 21 1 sides.Described external circulation heat exchanger 4 comprises outer circulation blower fan 41 and is arranged on the external heat exchanger 42 of these outer circulation blower fan 41 1 sides.
The utility model structural design is ingenious, reasonable, and described compressor 1, internal circulation heat-exchanging device 2, supplementary heat exchanger 3, external circulation heat exchanger 4, changement 5, expansion valve 6, gas-liquid separator 7 and cross valve 8 are connected and are formed the refrigerant circulation circuit of sealing by pipeline 10.
Under heating mode, by the work of compressor 1, the gas of refrigerant boil down to HTHP enters interior heat exchanger 22, enter supplementary heat exchanger 3 through cross valve 8, reject heat to the rear refrigerant condensation of baking room 9 and become the liquid of HTHP by interior circulating fan 21, enter the gas-liquid separator 7 with regenerative apparatus, with the further heat exchange of low temperature return-air, improve degree of supercooling, enter afterwards the liquid refrigerants that expansion valve 6 throttlings become low-temp low-pressure, entering external heat exchanger 42 evaporates again, become the gas of low-temp low-pressure by the airborne heat of effect absorbing environmental of outer circulation blower fan 41, enter the gas-liquid separator 7 with regenerative apparatus, with after the further heat exchange of condensed high-temperature liquid state refrigerant, get back to compressor 1, complete a circulation.Along with circulation is constantly carried out, the heat in surrounding air, just continually to being discharged in baking room 9, is realized drying effect, and not only efficiency utilization rate is high, also significantly shortens baking time, improve and dry efficiency, and dries quantity is good.
