It can be understood that the drying system comprises a heat pump unit, and the heat pump unit is respectively communicated with the first drying space 500 and the second drying space 600; the work flow of the drying spaces comprises a heating stage, an internal dehumidification stage, a heat exchange dehumidification stage and an evaporation dehumidification stage, and when one of the drying spaces is subjected to the heat exchange dehumidification stage and the evaporation dehumidification stage, the other drying space can be heated at the same time.
It will be appreciated that when the second drying space 600 is subjected to the heating phase, the temperature rise of the material is accompanied by an accelerated evaporation of the moisture, and the evaporation process requires a relatively large amount of heat to be absorbed, which may be from the auxiliary heating of additional heat or from the excess heat released during the dehumidification of the first drying space 500.
Referring to fig. 3, the drying system is in the first state, and it can be understood that, when the second drying space 600 performs the internal dehumidification, the second condenser 203 is operated while the fifth and sixth fans 120 and 121 are operated, and the second and eighth dampers 107 and 113 are opened; the first evaporator 201 in the first drying chamber 101 absorbs heat of the air of the second drying space 600 inputted to the first drying chamber 101 and uses the heat for heating the air of the second drying space 600; in the inner dehumidifying stage, the heat generated by the dehumidification is mainly used to heat the second drying space 600 or to keep the second drying space 600 at a constant temperature.
Referring to fig. 4, the drying system is in the second state, it can be understood that moisture is continuously evaporated during the internal dehumidification phase of the second drying space 600, and if the temperature in the second drying space 600 is difficult to maintain, the second drying chamber 102 can absorb the heat of the external air through the second evaporator 301, and then the absorbed heat is used to heat the air of the second drying space 600 through the fourth condenser 303.
Referring to fig. 5, the drying system is in the third state, it can be understood that moisture in the second drying space 600 is continuously evaporated, so that the moisture evaporation amount of the material is large, and the air in the second drying space 600 is in a high humidity and high heat state, so that the difficulty of dehumidification of the second drying space 600 is increased, and therefore, a heat exchange dehumidification stage of the second drying space 600 is required to cool the second drying space 600, so as to maintain the continuity of the dehumidification process.
It will be appreciated that the first fan 116, second fan 117, fourth fan 119 and fifth fan 120 are running and the first damper 106, fifth damper 110, sixth damper 111 and tenth damper 115 are open; the air of the second drying space 600 passes through the second heat exchange channel, the first air valve 106, the first fan 116, the fifth air valve 110 and the fifth fan 120 and then re-enters the second drying space 600; the air of the first drying space 500 is transferred along the first heat exchanging path and then re-enters the first drying space 500 after passing through the sixth air valve 111, the fourth air fan 119, the tenth air valve 115 and the second air fan 117.
It can be understood that the air of the first drying space 500 and the air of the second drying space 600 exchange heat in the heat exchanging device 400 in the dividing wall type heat exchanging direction, so that the temperature of the air of the second drying space 600 can be reduced, the dehumidification of the second drying space 600 can be facilitated, and in addition, the air of the first drying space 500 can absorb heat and raise the temperature.
Referring to fig. 6, the drying system is in the fourth state, it can be understood that as the dehumidifying process continues, the air temperature of the first drying space 500 increases, the air temperature of the second drying space 600 decreases, the temperature difference between the air of the first drying space 500 and the air of the second drying space 600 gradually decreases, the efficiency of heat exchange decreases, and the evaporation dehumidifying stage of the second drying space 600 is required.
It can be understood that the first evaporator 201 is communicated with the first condenser 202, the second fan 117, the fifth fan 120 and the sixth fan 121 are operated, the first evaporator 201 can absorb heat of the air of the second drying space 600 and heat the absorbed heat to the air of the first drying space 500 through the first condenser 202, the air of the second drying space 600 can release heat and reduce temperature, which is beneficial to the dehumidification process of the second drying space 600, and in addition, the air of the first drying space 500 can absorb heat and further increase temperature.
Referring to fig. 7, the drying system is in a fifth state, and it can be understood that, in order to increase the dehumidifying speed of the second drying space 600, the second drying chamber 102 may be communicated with the second drying space 600, the second evaporator 301 is activated, and the second evaporator 301 is communicated with the third condenser 302; the second evaporator 301 absorbs heat of air in the second drying space 600 and uses the absorbed heat to heat the air of the first drying space 500 through the third condenser 302.
It can be understood that, in the process of the heat exchange dehumidification phase and the evaporation dehumidification phase of the second drying space 600, the heat released by the second drying space 600 can be used to heat the first drying space 500, so as to complete the heating phase of the first drying space 500, so that the air temperature of the first drying space 500 rises, the evaporation amount increases, and the humidity increases.
It will be appreciated that the internal dehumidification phase of the first drying space 500 is similar to the internal dehumidification phase of the second drying space 600, and the first evaporator 201 absorbs heat from the air of the first drying space 500 input to the first drying chamber 101 and heats the air of the first drying space 500 through the first condenser 202 to achieve continuous evaporation of moisture in the material in the first drying space 500.
It can be understood that when the air in the first drying space 500 is in a high humidity and high temperature state and the dehumidification difficulty is large, the heat exchange of the air of the first drying space 500 and the air of the second drying space 600 is achieved by the heat exchanging device 400 to lower the temperature of the first drying space 500 and to raise the temperature of the second drying space 600.
It can be understood that when the temperature difference between the air in the first drying space 500 and the air in the second drying space 600 is small and the heat exchange efficiency is low, the first evaporator 201 is communicated with the second condenser 203, and the heat absorbed by the first evaporator 201 is used to heat the air in the second drying space 600, so as to lower the temperature of the first drying space 500 and raise the temperature of the second drying space 600.
It can be understood that the dehumidification process of the first drying space 500 and the dehumidification process of the second drying space 600 can form a cyclic process, so that the two drying spaces are mutually cold and heat sources, wherein the material of one drying room is heated first to evaporate the moisture of the material, and the heat released in the dehumidification process is used for heating the other drying room; after the dehumidification process of the two drying spaces is repeatedly carried out, the moisture of the materials in the two drying spaces is continuously evaporated and removed until the requirements are met, then the materials are respectively discharged from the kang, and the materials enter the next round of heating dehumidification process after being re-loaded into the kang.
It will be appreciated that when the heat of both drying spaces is not used up, the excess heat still needs to be discharged to the outside; at this time, the damp and hot air in the drying space can be replaced with the air in the external space by the seventh fan 122 at the fourth air opening 128, so as to reduce the temperature and humidity in the drying room.
