Enter condenser 10 after liquid refrigerant, the liquid refrigerant of low-temp low-pressure becomes low after absorbing atmospheric heat in condenser 10
The gaseous refrigerant of warm low pressure is sucked by compressor 8 then after the C mouth on three position four-way electromagnetic valve 9 is with S mouthfuls and completes circulation,
The surface layer air in grain depot 17 is pumped into after evaporator 12 heats up by return air hose 7 and is sent into again through air supplying hose 6 by system at this time
17 surface layer of grain depot, to suitably increase 17 skin temperature of grain depot；Outdoor fresh air enters condenser by outdoor fresh air import 2 simultaneously
10 temperature are discharged to outdoor from outdoor fresh air outlet 3 again after increasing.The device has the cooling of 17 surface layer of grain depot and the anti-condensation function of outbound
Can, cooling processing is being done to 17 surface layer of grain depot, to keep the temperature difference of 17 skin temperature of grain depot and grain heap surface temperature in " dew
Point " temperature is hereinafter, to prevent grain heap surface from condensing；It, can be according to the actual situation in advance by grain depot 17 when grain prepares outbound
Skin temperature increase so that the temperature difference of temperature and ambient temperature when grain outbound in " dew point " temperature hereinafter,
Moisture condensation when avoiding grain outbound, the grain moisture condensation problem during very good solution 17 grain storage of grain depot and grain outbound, into one
Walk the safety of the grain storage improved.
Preferably, in order to avoid the impurity in outdoor air enters in condenser 10 damage condenser 10, therefore can be with
It is equipped with strainer in the outdoor fresh air import 2 and outdoor fresh air outlet 3, fresh air can also be made cold by the strainer of setting
Condenser 10 does not generate disorder afterflow phenomenon, improves the heat exchange efficiency of condenser 10.
In order to which in cooling and temperature-rise period, when temperature and humidity reaches target value in grain depot 17, equipment is stopped automatically
Machine, so that further Ensuring Food Safety, can be equipped with automatic control device, the automatic control device in the shell 1
Including temperature sensor 15 and controller 16, the temperature sensor 15 is arranged in return air hose 7, and connects with controller 16
It connects, the controller 16 controls the start and stop of compressor 8.
The temperature sensor 15 is used to detect the return air temperature in return air hose 7 in return air, and the specific temperature passes
Sensor 15 is used to acquire the temperature signal in return air hose 7, and the temperature signal of acquisition is sent in controller 16, by adopting
The temperature signal of collection, the controller 16 is for realizing the control to compressor 8, control principle are as follows: if at this moment in silo 17
Temperature do not reach setting value, this device continues to run, if at this moment the temperature in silo 17 has reached setting value, control
Just control compressor 8 stops current operation to device 16.The controller 16 is the prior art, is not specifically described here, such as control
Device 16 processed can be using the minimum system of mature advanced single-chip computer and its peripheral circuit composition, to complete to compressor 8
