Drying course：
One, vacuum pump is opened, makes to dry indoor pressure decline, is automatically closed when pressure drops to certain value.And according to
Pressure change is automatically switched vacuum pump.
Two, compressor is opened, high temperature, high-pressure gaseous refrigerant is discharged, high temperature, high-pressure gaseous refrigerant enter heat exchanger, high
Temperature, high-pressure gaseous refrigerant release heat in a heat exchanger, become liquid high pressure refrigerant.The heat that refrigerant is released in a heat exchanger
Amount, to circulating heat conduction, matchmaker is heated.
Three, liquid high pressure refrigerant is depressurized by expansion valve, becomes low temperature, low-pressure liquid refrigerant enters condenser, low temperature, low
Pressure liquid refrigerants absorbs heat in condenser, and evaporation becomes low temperature, low-pressure gaseous refrigerant.Condenser temperature reduces, vapor
It is condensed into water within the condenser.Condenser ambient pressure reduces, and the water vapour in drying machine flows into condenser naturally, and by not
Disconnected is condensed into water, instills condensation drum bottom.
Four, low temperature, low-pressure gaseous refrigerant back into compressor, are compressed into high temperature again, high-pressure gaseous refrigerant enters hot friendship
Parallel operation.
Drying process：
Thermally conductive matchmaker is admitted to heating plate in hothouse after over-heat-exchanger is heated, through pipeline, to dried object into
Row heating.Dried object is heated, and contained humidity evaporating pressure increases, and water becomes vapor and releases.Cause dried object all
Steam pressure increase is enclosed, water vapour flows into condenser bucket by drying machine air inlet naturally, contacts with condenser, and temperature reduces,
Major part is condensed into water, instills condenser bucket bottom.Pressure reduction further attracts water vapour to enter condenser bucket.Small part
Water vapour and on-condensible gas form free convection, flow in hothouse through exhaust outlet.
Temperature reduces after thermally conductive matchmaker discharges heat, is pumped by liquid back pipe flow ipe, is forced into heat exchanger through pipeline pump,
It after thermally conductive matchmaker is heated in heat exchanger, flows out through outlet tube, dried object is heated into drying indoor heating plate.
With the increase of on-condensible gas content in hothouse, pressure can and then increase, when increasing to setting value, vacuum pump
It can start automatically, taking on-condensible gas away reduces the pressure of hothouse.
The effect of counter balance pocket is:Guarantee the abundance of thermally conductive matchmaker in the circulatory system.
After drying, vacuum pump, compressor, pipeline pump are successively closed；Later, intake valve is opened, air passes through filtering
After device filtering, through intake valve, into condensation drum and enter hothouse；Case is opened when external pressure reaches balance in hothouse room
Door takes out dried object.Finally, valve is opened, the water in condensation drum is excluded.
Feature：
The indoor absolute pressure of drying is dropped into water evaporation pressure corresponding to dried object drying temperature by vacuum pump,
But absolute pressure cannot be below 1KPa, dries indoor most air in this way and is evacuated, and surplus can be in thermodynamic computing
It ignores.In this way, dried object is in the drying process.Avoid unnecessary energy loss.Vacuum pump can intermittent running,
It reduces vacuum pump and continuously runs energy consumption.
The secondary vacuum condensation heat pump drier is material to be dried using heat pump, and hothouse is in endless authentic
Dummy status, but secondary vacuum state, it is dry to use source heat pump heat dry and condense time vacuum drying while carrying out, thus drying speed
Degree is fast, energy conservation, environmental protection.
