Description
Technical field
The utility model relates to a kind of dryer, is specifically related to a kind of heat pump dryer with dehumidification function.
Background technology
Heat pump dryer is in fact a kind of heat lift device, high temperature heat pump dryer group utilizes inverse Carnot's principle, draw heat from surrounding environment, and it is passed to by the object (object that temperature is higher) heated, its operation principle is identical with refrigeration machine, all according to inverse Carnot cycle work, difference is that operating temperature range is different.At present, drying plant generally adopts electrical heating type dryer or fuel-firing gas-firing etc. to provide heat, not only wastes energy, and the effect of dehumidifying can not be played, heat pump dryer with dehumidification function adopts compression refrigerating system, can not only economize energy greatly, and provides dehumidification function.
Summary of the invention
The purpose of this utility model there are provided a kind of heat pump dryer with dehumidification function, this dryer can not only provide hot blast to carry out heat drying to room air, also can carry out certain dehumidifying to room air, make the continuous removal moisture drying of room air, reach instructions for use.
The utility model is achieved like this, a kind of heat pump dryer with dehumidification function, comprise outdoor fan, evaporimeter 1, compressor, gas-liquid separator, four-way change-over valve, device for drying and filtering 1, evaporimeter 2, Bidirectional expansion valve, fin condenser, indoor fan, device for drying and filtering 2, liquid reservoir, it is characterized in that: compressor connects four-way change-over valve, four-way change-over valve connects fin condenser, fin condenser connects liquid reservoir, liquid reservoir connects device for drying and filtering 2, device for drying and filtering 2 connects Bidirectional expansion valve, Bidirectional expansion valve connects device for drying and filtering 2, device for drying and filtering 2 connects evaporimeter 2, evaporimeter 2 connects evaporimeter 1, evaporimeter 1 connects four-way change-over valve, four-way change-over valve connects gas-liquid separator, gas-liquid separator connects compressor, in addition, outdoor fan connects evaporimeter 1, indoor fan connects evaporimeter 2 and fin condenser.
During unit work, cold-producing medium is periodic duty in refrigeration systems, to play the effect of cold delivered heat.Room air is drawn through evaporimeter 2 and fin condenser by indoor fan.Room air first after evaporator 2 dehumidifies, then heats through fin condenser, to reach the object of room air drying.Outdoor air is drawn through evaporimeter 1 by outdoor fan.During defrosting, four-way change-over valve commutates, refrigeration system inverted running, melts on evaporimeter.

In the drawings 1, outdoor fan 2, evaporimeter 13, compressor 4, gas-liquid separator 5, four-way change-over valve 6, device for drying and filtering 17, evaporimeter 28, Bidirectional expansion valve 9, fin condenser 10, indoor fan 11, device for drying and filtering 2 12, liquid reservoir.
Detailed description of the invention
As shown in Figure 1, the utility model comprises outdoor fan (1), evaporimeter 1(2), compressor (3), gas-liquid separator (4), four-way change-over valve (5), device for drying and filtering 1(6), evaporimeter 2(7), Bidirectional expansion valve (8), fin condenser (9), indoor fan (10), device for drying and filtering 2(11), liquid reservoir (12), it is characterized in that compressor connects four-way change-over valve, four-way change-over valve connects fin condenser, fin condenser connects liquid reservoir, liquid reservoir connects device for drying and filtering 2, device for drying and filtering 2 connects Bidirectional expansion valve, Bidirectional expansion valve connects device for drying and filtering 2, device for drying and filtering 2 connects evaporimeter 2, evaporimeter 2 connects evaporimeter 1, evaporimeter 1 connects four-way change-over valve, four-way change-over valve connects gas-liquid separator, gas-liquid separator connects compressor, in addition, outdoor fan connects evaporimeter 1, indoor fan connects evaporimeter 2 and fin condenser.
Unit work time, cold-producing medium by discharging after compressor compresses, through four-way change-over valve, then by fin condenser condensation, condensed cold-producing medium through liquid reservoir, after device for drying and filtering 2, after Bidirectional expansion valve reducing pressure by regulating flow, drying filter 1 arrives evaporimeter 2 again, after evaporimeter 2 vaporized in part, again through evaporator 1 evaporimeter completely, then through four-way change-over valve, compressor got back to by gas-liquid separator, so circulates.
Room air is drawn through evaporimeter 2 and fin condenser by indoor fan.Room air first after evaporator 2 dehumidifies, then heats through fin condenser, to reach the object of room air drying.
Outdoor air is drawn through evaporimeter 1 by outdoor fan.
During defrosting, four-way change-over valve commutates, and cold-producing medium is by discharging after compressor compresses, through four-way change-over valve, then by evaporimeter 1, evaporimeter 2, then through device for drying and filtering 1, Bidirectional expansion valve, device for drying and filtering 2, liquid reservoir, after entering fin condenser, get back to compressor through four-way change-over valve, gas-liquid separator again, so circulate.
