Detailed description of the invention
As shown in Figure 1, a kind of heat pump drying dehumidifier, comprise air compartment, blower fan 2 is provided with in air compartment, second heat exchanger 3, air compartment is outside equipped with First Heat Exchanger 8, 3rd heat exchanger 4, compressor 1, expansion valve 9, first magnetic valve 6, second magnetic valve 5, check valve 7, wherein air compartment air outlet is successively by air delivery duct 10, air-return duct 11 contacts with the 3rd heat exchanger 4 and connects, 3rd heat exchanger 4 is contacted with the second heat exchanger 3 in air compartment by connection air channel and connects, the entrance of the second heat exchanger 3 is communicated with by the exhaust outlet of pipeline with compressor 1, the outlet of the second heat exchanger 3 fills 9 by pipeline and throttling expansion and puts inlet communication, expansion valve 9 export by pipeline respectively with the first magnetic valve 6, the inlet communication of the second magnetic valve 5, the outlet of the second magnetic valve 5 is by the inlet communication of pipeline and the 3rd heat exchanger 4, the outlet of the first magnetic valve 6 is by the inlet communication of pipeline and First Heat Exchanger 8, the outlet of First Heat Exchanger 8 is by the inlet communication of pipeline and check valve 7, the outlet of check valve 7, the outlet of the 3rd heat exchanger 4 is communicated with the air entry of compressor 1 jointly by pipeline.
Blower fan 2 drives institute's drying dehumidification air to flow through the 3rd heat exchanger 4 and the second heat exchanger 3 carries out heat exchange, and First Heat Exchanger 8 carries out heat exchange with outside ambient air or current.
In the utility model, heat pump drying dehumidifier, by the opening and closing of the first magnetic valve 6 and the second magnetic valve 5, switches to heat pump to heat and the intensification two kinds of operational modes that dehumidify, needs to carry out reasonable set selection according to user.
In the utility model, in the heat pump heating mode of this unit, First Heat Exchanger 8 is as the evaporimeter of heat pump, and the 3rd heat exchanger 4 does not work, and the second heat exchanger 3 is as the condenser of heat pump; Air handled by this unit flows through the 3rd heat exchanger 4 and the second heat exchanger 3 successively, occurs without heat exchange when flowing through the 3rd heat exchanger 4, then flows through the condensation heat of absorbent refrigeration system during the second heat exchanger 3 and raised temperature.
In the utility model, in the dehumidifying heating mode of this unit, First Heat Exchanger 8 does not participate in heat exchange substantially, second heat exchanger 3 is as the condenser of heat pump, 3rd heat exchanger 4 is as the evaporimeter of heat pump, and when check valve 7 prevents from dehumidifying running, refrigeration working medium is to migration in the lower First Heat Exchanger 8 of temperature; Air handled by this unit flows through the 3rd heat exchanger 4 and the second heat exchanger 3 successively, when flowing through the 3rd heat exchanger 4, temperature reduces thus removes the part moisture content in air, the condensation heat of absorbent refrigeration system when then air flows through the second heat exchanger 3 and raised temperature.
Now the course of work of the present utility model is described in detail, first preheating can be carried out to institute's drying dehumidification air by heat pump heating mode, reach temperature required, then select dehumidifying heating mode again to institute's drying dehumidification air-treatment, make it to be in low humidity, and maintain higher temperature, therefore this gas has very efficient drying dehumidification effect to dried object.
Heat pump heating mode, as shown in Figure 2: the first magnetic valve 6 is communicated with, the second magnetic valve 5 cuts off, now the 3rd heat exchanger 4 does not work, First Heat Exchanger 8 is as the evaporimeter of heat pump cycle, refrigeration working medium evaporation wherein also absorbs heat from unit outside, and (the mode evaporimeter of air-source directly absorbs heat from outside air specifically can to adopt the mode at air-source or water source; The mode at water source is that evaporimeter absorbs heat from extraneous current), refrigeration working medium absorb external heat, enter compressor 1 by the road, by compression raised pressure after, enter the second heat exchanger 3, refrigeration working medium condensation wherein and by thermal release to dry in air; Dry air under the driving of blower fan 2, flow through the 3rd heat exchanger 4, second heat exchanger 3 successively via air-return duct 11, be then transported in drying dehumidification space to 10 by air draft.Now flow because the second magnetic valve 5 cuts off refrigeration working medium in the 3rd heat exchanger, so there is no heat exchange; Condenser heat is released in dried air by the second heat exchanger 3, achieves this gas-heated by heat pump cycle.
Dehumidifying heating mode, as shown in Figure 3: the first magnetic valve 6 cuts off, the second magnetic valve 5 is communicated with, second heat exchanger 3 is as the evaporimeter of heat pump, now First Heat Exchanger 8 not heat exchange, check valve 7 prevents refrigeration working medium to migration in the lower First Heat Exchanger 8 of temperature, and the second heat exchanger 3 is as condenser; Refrigeration working medium absorbs heat in the 3rd heat exchanger 4, waits associated refrigeration parts to enter compressor 1 by the road, after compression raised pressure, enters the second heat exchanger 3, refrigeration working medium condensation wherein release heat, by thermal release to dry in air; Under the driving of blower fan 2, institute's drying dehumidification air rejects heat in refrigeration working medium when flowing through the 3rd heat exchanger 4 via air-return duct 11, thus institute's drying dehumidification air is lowered the temperature and is discharged moisture content, then airflow passes second heat exchanger 3, absorb heat wherein, the principle of evaporimeter heat is greater than according to kind of refrigeration cycle condenser heat, temperature when institute's drying dehumidification air leaves the second heat exchanger 3 will be slightly higher than temperature when entering air-return duct 11, will then be transported in drying dehumidification space to 10 by air draft.Through this flow process, institute's drying dehumidification air is through dehumidifying and heating up, and dry hot-air has better dries and effect on moisture extraction.
Refrigeration working medium according to dry materials characteristic, can be selected high temperature refrigerant or normal temperature working medium, meets the drying requirement of different disposal object respectively.
