Detailed description of the invention:
Embodiment is described in detail as it is shown in figure 1, this heat pump drying equipment 1 is by drying chamber 2, return airway in conjunction with the figures above
5 and heat pump machine hall constitute, described drying chamber is positioned at the bottom of heat pump machine hall, and return airway 5 is positioned at the top of drying chamber, heat
Pump machine hall is arranged at the top of return airway 5.
Being sequentially installed with circulating fan 15 and heater 16 in described return airway 5, heater is to use heat pump condenser,
Return airway is provided with new wind air door 12 on the extraneous side wall connect, for introducing the dry air in the external world, return airway and heat
Arrange between pump machine hall 7 and wet-emitting blower 6 is installed, the Hot wet air heating in drying chamber is arranged by wet-emitting blower by return airway
Enter in heat pump machine hall.
Described drying chamber 2 is built-in is placed with loading attachment 3, and loading attachment is placed the material 4 needing to be done, and air is at return air wind
By circulating fan, hot-air is sent in drying chamber after being heated by the heaters in road, for the drying of material.
It is placed with heat pump main frame 11 in described heat pump machine hall, can be selected one or more according to the number of drying materials
Installing, described heat pump machine hall is provided with air door 8 on a side wall of wet-emitting blower 6, the wall of opposite side is provided with air draft
Blower fan 14, built with machine hall's temperature sensor 13 of measurement temperature, there is measurement ring heat pump machine hall outside heat pump drying equipment
The environment temperature sensor 9 of border temperature, heat pump main frame 11 is placed in heat pump machine hall 7, heat pump machine hall and heater 16 it
Between connected by copper pipe 10, be used for transmitting coolant, constitute complete heat pump, thus be reached for drying equipment supply heat it
Purpose.
During work as in figure 2 it is shown, this duty be not dehumidifying, do not introduce the duty of new wind, now due to main frame
Dehumidifying heat in the interior dehumidifying heat supply without drying equipment in room 7 or heat pump machine hall 7 has made full use of, in machine hall
Temperature and ambient temperature basically identical (or slightly below ambient temperature), now exhaust fan 14 and air door 8 are opened simultaneously, machine hall
Carrying out heat exchange with external environment, it is ensured that heat pump is properly functioning, this duty works with common heat pump drying device
Process is identical；
As it is shown on figure 3, this duty is dehumidifying, introduces the duty of new wind, now dry owing to receiving in machine hall 7
The dehumidifying heat of dry equipment, main frame indoor temperature can be higher than ambient temperature, now simultaneously closes off exhaust fan 14 and air door 8, row
Damp and hot amount can be improved heat pump heating capacity and heat pump efficiency by heat pump host computer.Due to the Hot wet air heating discharged from drying equipment
Temperature is higher, humidity is relatively big, can be the biggest by the heat of heat pump host computer.Rely on the space that heat pump main frame is formed, not filling
Divide the heat utilized again to recycle, until machine hall's temperature is less than after ambient temperature, open exhaust fan 14 and wind simultaneously
Door 8, utilizes outside air to carry out heat exchange；On the other hand dehumidifying is relied on to discharge the moisture in material during heat pump drying,
Dehumidifying process accounts for the large percentage of total dry run, and dehumidifying Btu utilization is considerable, even if at low ambient temperatures, heat pump steams
Sending out temperature will not be the lowest, can improve heat pump heating capacity and heat pump Energy Efficiency Ratio by a relatively large margin.This drying equipment running status is this reality
By novel feature.
Described exhaust fan 14 and air door 8 are by intelligent controller control, and concrete intelligence controls to can be selected for PLC or single-chip microcomputer,
Concrete control is as described below:
Described exhaust blower 14 and air door 8 are affected by environment temperature sensor 9 and machine hall's temperature sensor 13, intelligence control
Device processed controls it and is turned on and off；It specifically controls logic:
A, when machine hall's temperature is less than ambient temperature, exhaust fan 14 and air door 8 open simultaneously, and heat pump main frame is with extraneous
Air carries out heat exchange；
B, when machine hall's temperature is not less than ambient temperature, exhaust fan 14 and air door 8 simultaneously close off, heat pump main frame and master
Machine room air carries out heat exchange；
C, when machine hall's temperature higher than 40 DEG C (actual temp numerical value is adjustable according to different situations) time, exhaust fan 14 and wind
Door 8 is opened simultaneously, forces the air of excessive temperature to discharge machine hall, prevents heat pump main frame electric current too high.
