Detailed description of the invention
See Fig. 1, a kind of rapidly pre-warming type air source heat pump dryer, include compressor 1, four-way change-over valve 2, extraneous air heat exchanger 3, first, two inner air heat exchanger 7a, 7b, first, two expansion valve 5a, 5b, first, two, three, four check valve 8a, 8b, 8c, 8d and liquid reservoir 9, the outlet of compressor 1 is connected with the main import of four-way change-over valve 2, one side outlet of four-way change-over valve 2 is connected with a side interface of extraneous air heat exchanger 3, first expansion valve 5a is with the first check valve 8a phase and after connecing, be connected with the opposite side interface of extraneous air heat exchanger 3 on the one hand, be divided into two branch roads on the other hand, one of them branch road connects successively the first inner air heat exchanger 7a and the 3rd check valve 8c, another branch road connects the second check valve 8b, the end of two branch roads is compiled in a place and is connected with one end of liquid reservoir 9, second expansion valve 5b is with the 4th check valve 8d phase and after connecing, be connected with the other end of liquid reservoir 9 on the one hand, be connected with a side interface of the second inner air heat exchanger 7b on the other hand, the opposite side interface of the second inner air heat exchanger 7b exports with the opposite side of four-way change-over valve 2 and is connected, and the central exit of four-way change-over valve 2 connects the import of gas-liquid separator 10 rear access compressor 1.
In the utility model, the first expansion valve is pre-thermal expansion valve, and the second expansion valve is dehumidifying expansion valve.
System needs to adopt controller 11, and controller 11 is for realizing the control of the parts such as compressor, four-way change-over valve, blower fan, electronic valve (electric expansion valve, magnetic valve), adjustment.
External heat-exchanging blower fan 4 provides the air of extraneous air heat exchanger 3 to circulate, and internal heat blower fan 6 provides the air of first and second inner air heat exchanger 7a, 7b to circulate respectively.
Below in conjunction with accompanying drawing, the utility model is further described:
First by heat pump mode, preheating heating is carried out to the air in insulation drying room, make it reach material preheating temperature required, be conducive to the evaporation of moisture in material, and then material is dried.The humidity that in drying materials process, air produces, then dehumidified by the mode of desiccant dehumidification, reclaimed heat.
The utility model omnidistancely can adopt Automated condtrol, does not need human users to realize auto-drying, and by monitoring dehumidifying space air temp state, realize the switching to four-way change-over valve, system enters warm-up operations respectively and removes wet cooling condition.Before unit operation, detection space air themperature, when temperature is lower than design temperature, then enters preheating mode, and dehumidifying space is rapidly heated; After design temperature, system enters dehumidification mode.
See Fig. 2, refrigeration working medium flows to the second inner air heat exchanger 7b through compressor 1 by four-way change-over valve 2, after the 4th check valve 8d, (two-way flow) receiver 9 flow to the first expansion valve 5a throttling, enter extraneous air heat exchanger 3, after the heat transmitted by absorption outer loop air (being driven by external heat-exchanging blower fan 4), refrigeration flashes to low-pressure gas state man-hour, compressor 1 is flowed back to successively through four-way change-over valve 2, gas-liquid separator 10, circulate according to this, outdoor low level air heat energy is transferred to dries space.
See Fig. 3, compressor 1 refrigeration working medium is compressed into high pressure gaseous from low temperature low pressure gas state, through flowing to extraneous air heat exchanger 3 by four-way change-over valve 2, external heat-exchanging blower fan 4 does not now run, namely working medium is dispelled the heat less when outside air heat exchanger flows through, the first inner air heat exchanger 7a is flow to again through the first check valve 8a, highly pressurised liquid is become after this release heat is to recirculate air inside (being driven from internal heat blower fan 6), through the 3rd check valve 8c, receiver 9 flows through the second expansion valve 5b throttling, after throttling, refrigeration working medium flashes to low-pressure gas state in the second inner air heat exchanger 7b heat absorption, successively through four-way change-over valve 2, gas-liquid separator 10 flows back to compressor 1, circulate according to this, dry space air (and even material) and realize dehumidifying and rewarming or intensification.
Whether external heat-exchanging blower fan can according to being that temperature-adjusting type dryer or heating type dryer determine whether to need speed governing, if temperature-adjusting type dryer, and ventilator selection speed-changing draught fan; If heating type, then during initial launch, blower fan is stopped transport.
Refrigeration working medium can according to dry materials characteristic, and select high temperature refrigerant or normal temperature working medium respectively, usual R134a working medium can meet less than 80 DEG C high temperature drying room temperature requirements.
Due to the difference of two kinds of operating modes, set up corresponding expansion valve throttling device separately, according to electric expansion valve, due to the modulability that it is good, can be merged into single, automatically adjust.
Section components, as device for drying and filtering, liquid-sighting glass, (electromagnetism, manually) valve etc., generally all can arrange in systems in which, to ensure safe operation and the management of system as required.The parts such as receiver, gas-liquid separator, device for drying and filtering, liquid-sighting glass, (electromagnetism, manually) valve generally all adopt, but do not adopt and also do not depart from protection domain of the present utility model.
