Please refer to Fig.3 and Fig. 5, the air circulation process in box heat pump drying case 100 is as follows：Contain refrigeration in babinet 13
Agent gas.The flow direction of refrigerant gas is as arrows in fig. 5.First, the refrigerant gas of high temperature and pressure is from compressor 18
In out enter by electrically controlled 4-way valve 15 in parallel the first condenser 17a and the second condenser 17b by the gas of side wall 121
Discharge orifice 203 carries out heat exchange with the air in internal cavity 202 and (with reference to figure 3, does not place supporting plate 21 in Fig. 3, do not place supporting plate
Airflow direction when 21 is as shown in Figure 3), after heat exchange, refrigerant gas is changed into medium temperature high pressure from high temperature and pressure, then refrigerant
Gas is filtered by filter 26 and capillary 27 throttles is changed into the liquid of low-temp low-pressure, then enters parallel connection by check valve 24
The first evaporator 16a and the second evaporator 16b in be evaporated the gas for becoming normal temperature and pressure, the refrigerant gas of normal temperature and pressure
Body is constantly forced to carry out heat exchange with air by fan 23, then is returned to through electrically controlled 4-way valve 15 in compressor 18.The above process by
Centrifugal blower 19 is forced the air circulation in babinet 13 and is completed, and constantly repeats above-mentioned air circulation process, makes in babinet 13
Air themperature constantly raises, and the moisture of the article of needs drying is constantly taken away, from the air-flow of the roof 122 of door shape partition plate 12
Hole 203 is discharged, and when the air themperature in internal cavity 202 rises to a timing, automatic relieving valve 25 is started to work, will be a part of high
The refrigerant gas of warm high pressure is discharged into the 3rd evaporator 16c, is returned directly to by electrically controlled 4-way valve 15 in compressor 18, can
The air themperature in internal cavity 202 is set to rise to obtain higher.
Please refer to Fig.1 to Fig. 5, the specific operation process of box heat pump drying case 100 is as follows：Chamber door 11 is opened, first will card
Close convex 21a and engage with engaging recessed 121a, form drying chamber 202a；The article of required drying is put into, will according to the height of humidity
Article is put into drying chamber 202a, and the low article of humidity is placed in the drying chamber 202a on upper strata, humidity it is high be placed on lower floor
Drying chamber 202a in；The parameters such as temperature, the humidity of each drying chamber 202a are set using controller 14, are closed after being provided with
Chamber door 11；Open box heat pump drying case 100, the air circulation in 19 drive case 13 of centrifugal blower, refrigerant gas is continuous
Carrying out heat exchange with air in internal cavity 202 makes the temperature in internal cavity 202 constantly raise；After heat exchange, added using fan 23
Refrigerant gas in fast evaporator 16 and air carry out heat exchange, the airflow circulating in babinet 13 constantly make needed for it is dry
The moisture of article is discharged from the airflow hole 203 of roof 122；During drying, each drying is detected by sensor 22
The parameter feedbacks such as the temperature and humidity of chamber 202a contrast set parameter into controller 14, and wind is controlled by controller 14
The power of fan 23 and centrifugal blower 19 also utilizes sensor untill reaching the temperature needed for each drying chamber 202a
Situation in the data of 22 feedbacks and the babinet 13 observed from chamber door 11, judges whether drying smoothly carries out；If occur
Emergency case, stops the work of box heat pump drying case 100 in time；After the completion of drying, dried article is taken out, by supporting plate
21 up push up, and the convex 21a of engaging is departed from engaging recessed 121a, and supporting plate 21 is exited drying chamber 202a, closes chamber door 11 and electricity
Source.Certainly when needing the article of dry high-volume same type, without engaging supporting plate 21, directly dry article is put into dry
In dry chamber 202a, drying can be started after setting parameter using controller 14.
The foregoing is merely embodiment preferred for this invention, it is impossible to the interest field of the present invention is limited with this.At this
In the concept of invention, corresponding change can be reasonably made.Therefore, protection scope of the present invention should be with claims
Subject to.
