Embodiment 1
Refering to fig. 1 shown in -3, a kind of low temperature dehumidification machine suitable for freezer, includes shell 1, and be installed in shell 1
Condensing plant 2, the downside of the shell 1 offers return air inlet 11, and the condensing plant 2 includes 21 He of the first condenser
Second condenser 22, what first condenser 21 was connected to each other with return air inlet 11, second condenser 22 is located at the first condensation
21 top of device is equipped with first pipe 23 and connects between first condenser 21 and the second condenser 22, the first pipe 23
On the first solenoid valve 231 is installed, first condenser 21 is also connected with evaporator 24, first condenser 21 and evaporator
Second pipe 25 is equipped between 24, the second pipe 25, which is equipped with pressure switch 251 and is connected with compressor 252, is forwarded to steaming
Device 24 is sent out, the pressure switch 251 is connected with pressure controller 253, and first solenoid valve 231 is connected with humidity controller 232, institute
It states pressure controller 253 and humidity controller 232 to be electrically connected, the is additionally provided between first condenser 21 and evaporator 24
Three pipelines 26 are successively arranged filter 261 and second solenoid valve 262 on the third pipeline 26, and the upper side of the shell 1 is set
