It is cooling, it then by second heat exchanger, is further cooled at second heat exchanger, then passes through third heat exchanger,
It is heated, is then return in roller at third heat exchanger.The present invention is particularly useful for closed loop heat pump clothes dryer.
Background technique
As shown in Figure 1, known heat pump clothes dryer 1 includes for making the closed circulation for handling air P circulation or being closed back
Road L.A component of closed circuit L is the roller 2 for receiving wet clothes or clothing to be dried.Air P is handled to utilize
Fan 3 is recycled.For example, processing air P is discharged from the exhaust outlet 2b (operating point p1) of roller 2 during drying cycles.?
There, relative humidity rh1 of the processing air P with about 40 DEG C of medium temperature T1, high absolute humidity and about 85% or 0.85.Place
Air P is managed subsequently into heat exchanger namely the air inlet 4a of the evaporator 4 of compression heat pump H.There, air P quilt is handled
Its dew point is cooled to hereinafter, to generate condensate C particularly by making processing air P be in contact with the surface of evaporator 4.By
Thus the processing air P of exhaust outlet 4b (at the p3 of the operating point) discharge of evaporator 4 has about 32 DEG C of relatively low temperature water
Flat T3 is about 100% with significantly lower absolute humidity and close to its saturation point or the relative humidity rh3 of saturation, i.e. rh3
Or 1.Air P is handled subsequently into other heat exchanger-and the air inlet 5a of the condenser 5- of heat pump H.It is vented when passing through
When mouth 5b (operating point p5) is discharged, temperature has risen to about 73 DEG C of the horizontal T5 of high-temperature, while keeping absolute humidity
It is constant.However, relative humidity rh5 falls to approximately 13%.This to handle air P can be from wet after reentering roller 2
Moisture is absorbed in clothes.By absorbing moisture from wet clothes, the relative humidity of processing air P is again raised to about 85%
Rh1, temperature drop to by-level T1.Since processing air P is recycled in the closed circuit, so the process is repeated, until
Clothing reaches a certain target humidity or target humidity rate.
If adjacent exhaust outlet 2b, 4b, 5b and air inlet 4a, 5a and 2a is located next to, and/or if adjacent air inlet
Influence of the air pipeline to processing air P between exhaust outlet is negligible, then for these air inlets and exhaust outlet, processing is empty
The situation of gas P and operating point are correspondingly identical.
The operation of heat pump clothes dryer 1 can be controlled by control device, such as central control circuit 13.
The temperature difference between heat exchanger (i.e. evaporator 4 and condenser 5) is formed due to compression heat pump H, wherein fluid
(or refrigerant R) is compressed to from low pressure/low-temperature condition overheated gas state in high pressure/high temperature situation by compressor 6
Overheated gas state.At elevated pressure, saturation of the refrigerant at the bubble point under the pressure equal or close to refrigerant R
Subcooled liquid is condensed into condenser 5 (thus it is used as refrigerant-air formula heat exchanger) at a temperature of temperature.Refrigerant
R then reach expansion valve 7, equal or close to the dew point of refrigerant R at this pressure saturation temperature at a temperature of be expanded into
Low stress level, to reach two-phase state, then in evaporator 4 (thus it is used as air-refrigerant heat exchanger)
Middle evaporation, to reach overheated gas state again.
