Description of the drawings
Fig. 1 is this utility model structural representation.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.
A kind of hot-gas bypass heat pump constant temp. drying box as shown in Figure 1, including compressor 1, the connection condenser 2 of compressor 1
Connection, the connection choke valve 3 of condenser 2, the connection vaporizer 4 of choke valve 3, vaporizer 4 are connected with compressor 1, are set by vaporizer 4
It is equipped with blower fan 5；Condenser 2 is arranged in condenser shell 10, is provided with pressure fan 6, condenser by 10 inner condenser 2 of condenser shell
Shell 10 and drying baker 7 connect, and pressure fan 6 can be blown into drying baker 7, connect heat on the pipeline that compressor 1 is connected with condenser 2
One end of gas bypass valve 8,8 other end of hot gas bypass valve are connected with the pipeline for being connected choke valve 3 and vaporizer 4.
As one kind preferred embodiment, hot gas bypass valve 8 adopts electric expansion valve.Humiture is set in drying baker 7
Sensor 9.
A kind of hot-gas bypass heat pump constant temp. drying box of the present utility model, specific implementation process is：
The high temperature and high pressure gas that compressor 1 is discharged enter condenser 2,2 cool down and condense and become supercooled liquid within the condenser
Body, its liberated heat are taken away by air, then vaporizer 4 is entered after 3 reducing pressure by regulating flow of expanded valve, and vaporizer 4 is flow through in absorption
Become superheated steam to be inhaled in compressor 1 after the heat of air, so as to complete the circulation of coolant system；
Air is cooled in the dirty pervaporation device 4 of driving of blower fan 5；
Fresh air sends into drying baker 7 in dirty the mistake after condenser 2 is heated of driving of pressure fan 6；
According to the adjustable cold medium flux into condenser 2 of the work of signal hot gas bypass valve 8 that Temperature Humidity Sensor 9 is provided
So as to realize that heating amount adjusts temperature in constant drying baker 7.
The above is only preferred implementation of the present utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
