Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram of the utility model closed type hot pump drying system as Figure 1-Figure 2, comprises compressor 5, vortex tube 7, condenser 4, condenser coil 3, heating power expansion valve 2, evaporimeter 10, first evaporation coil 1, hothouse 6, electronic by-passing valve 9, cooler 8, evaporimeter 10 and the second evaporation coil 11.Frequency-changeable compressor selected by compressor 5 in the present embodiment.Described condenser coil 3 is placed in described condenser 4, and described second evaporation coil 11 is placed in described evaporimeter 10.The outlet of described compressor 5 is connected with the inlet connection 14 of described vortex tube 7, the hot junction discharge connection 15 of described vortex tube is connected with the entrance of described condenser coil 3, the outlet of described condenser coil 3 is connected by the entrance of described heating power expansion valve 2 with described first evaporation coil 1, the cold side outlet adapter 17 of described vortex tube is connected with the entrance of described second evaporation coil 11, and the outlet of described second evaporation coil 11 is connected with the entrance of described compressor 5 with after the outlet parallel connection of described first evaporation coil 1.The outlet of described condenser 4 is connected with the entrance of described hothouse 6, the outlet of described hothouse 6 is divided into two branch roads, one tunnel is connected with the entrance of described cooler 8, another road is connected with the entrance of described electronic by-passing valve 9, the outlet of described electronic by-passing valve 9 is connected with the entrance of described evaporimeter 10 with after the outlet parallel connection of described cooler 8, and the outlet of described evaporimeter 10 is connected with the entrance of described condenser 4.Described evaporimeter 10 lower end is connected with condensation water drainage pipe 12, and the export pipeline of described evaporimeter 10 is provided with humidity sensor 13, and described humidity sensor 13 is connected by holding wire with described electronic by-passing valve 9.
