Mode improve air themperature, make stream of hot air through clothing surface under fan action, the water of clothing taken away by hot and humid area
Point, realize the acceleration drying of clothing.Cheap because its structure is simple, electrothermal dryer accounts for exhausted most market share.But
Since electrothermal dryer directly uses electric-heating-wire-heating air, a large amount of electric energy is consumed, and pass through the higher temperatures high humidity of clothing
Air-flow be directly discharged into interior, hot wet soiling can be caused to interior.In order to solve the problem above of electrothermal dryer, expedite the emergence of
Heat pump clothes dryer.
Heat pump clothes dryer is a kind of Novel clothes (or textile) drying equipment using heat pump techniques.In heat pump clothes dryer
In system, there are heat pump cycle and two closed cycles of air circulation, two cycle through evaporator and condenser progress heat
Exchange.In heat pump cycle, by compressor work, a small amount of electric energy is consumed, refrigerant circulation is driven, makes refrigerant in evaporator
It is middle absorb exhaust waste heat and condensed water from drying bucket latent heat, within the condenser with higher temperature reject heat to by into
Enter the air of drying bucket.In air circulation, under the promotion of blower, the damp-heat air being discharged from drying bucket is in evaporator
Reduce temperature, and the moisture in condensation air；The air of the low water capacity of low temperature is heated up by condenser later, but water capacity
Constant, relative humidity reduces, and air absorbs the very capable of moisture at this time；Finally, the air of high temperature low relative humidity blows over clothing
Object surface, clothing carry out hot and humid area, release heat, take away moisture.Since system continually enters electric energy, to maintain circulation air
Energy balance, system need to pass through setting auxiliary cooler, auxiliary condenser or supplement fresh air maintain system stablize.Heat pump clothes-drying
Machine has many advantages, such as that energy consumption is low, small on indoor air quality influence, drying effect is good；Meanwhile the drying temperature of heat pump clothes dryer
Lower than electrothermal dryer, the damage that air temperature is too high to clothing surface is avoided.
