Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model patent apparent
Explicitly define.
Referring to Fig. 1, the utility model embodiment:
A kind of enclosed heat pump drying device with tandem auxiliary condenser, comprising: cabinet 1, heat pump system, cabinet 1
Interior to be equipped with drying room 2,2 inside upper part of drying room is equipped with drying room exhaust outlet 3, and lower part is equipped with drying room air inlet 12.It is drying
Material is placed in room 2 and drying and processing is carried out to the material by dried medium.The refrigerant circuit of heat pump system are as follows: pressure
Contracting machine 10, main condenser 8, auxiliary condenser 11, throttle valve 6 and evaporator 4 pass sequentially through pipeline 9 and are connected, and refrigerant is in pipeline
Flowing in 9.Wherein the compressor 10 and auxiliary condenser 11 are mounted on the outside of cabinet 1；Auxiliary condenser 11 is board-like
Heat exchanger is connected with main condenser 8, and is placed on 8 downstream of main condenser；The evaporator 4 is mounted on the exhaust of drying room 2
