As a preference, described dehumidifying coil 5 and in opposite directions air-flow heat exchange coil 4 are that the roundabout heat pipe of many groups comes and goes and passes through Multi-layer exchanging heat sheet and the liquid-gas-heat exchanger of combining closely, the aluminium flake that wherein heat exchanger fin is vertically arranged in parallel by multi-disc forms, and heat pipe is the parallel roundabout copper pipe of many groups and penetrates respectively in heat exchange film perforation and to closely cooperate.In addition, hot-blast coil pipe 7 also can adopt said structure.
Described including in the heat pump circulating chilled water pipeline of dehumidifying coil 5, in opposite directions air-flow heat exchange coil 4 and external radiator 6 is provided with flow controller 9, in heat pump circulating chilled water pipeline circulate refrigerant and heat pump refrigeration end carry out heat exchange.
The below of described dehumidifying coil 5 is provided with condensate drain pan, and described condensate drain pan has discharge outlet.
During heat pump dryer real work, in the heat pump circulating chilled water pipeline be connected with heat pump cold water circulating system, low-temperature cold water is entered by the outer field heat pipe of dehumidifying coil 5 by variable frequency pump, and the outlet finally by the outer field heat pipe of air-flow heat exchange coil 4 is in opposite directions flowed out.The damp-heat air that drying room is discharged is entered by air inlet, to project passing through of the region of occuring simultaneously from air-flow heat exchange coil in opposite directions 4 and dehumidifying coil 5, before air arrives dehumidifying coil 5 again, wherein portion of air is discharged from moisture exhausting port 8, another part air continues down by after dehumidifying coil 5, turn back again to air-flow heat exchange coil 4 in opposite directions another part region and flow out from air outlet, enter heat pump condenser afterwards, finally enter drying room.The inlet air flow path crossing wind path footpath 31 is U-shaped, damp-heat air flow through downwards in opposite directions air-flow heat exchange coil 4 time, air themperature progressively reduces and close to dew point, wherein a part of low temperature is also discharged from moisture exhausting port 8 close to saturated steam, separate out moisture when the air of remainder continues through temperature lower dehumidifying coil 5 and complete dehumidification by condensation process, heat wherein can be absorbed when the Cryogenic air after dehumidifying coil 5 dehumidification by condensation is turned back and flowed through air-flow heat exchange coil 4 in opposite directions, form the air flowed out and indirectly absorb the heat entering air in opposite directions, heated by heat pump condenser again after making air return to certain temperature, finally enter drying room.
Originally the drying room of design is under megathermal climate, cold water after dehumidifying due to outdoor environment medium temperature too high and can not externally dispel the heat, externally heat radiation ensures that the cold and hot balance of heat pump can not realize in this way, like this, just can only select to heat link from heat pump condenser or install exhaust outlet discharge high temperature air additional at drying room to dispel the heat, no matter that mode, the heating energy efficiency ratio of heat pump is sacrificed in capital, equal the heat by compressor work being produced is drained and wastes, so, separately incidentally take a breath tradition it runs and to be restricted or energy consumption increases in high temperature environments for the drying room of hydrofuge by the drying room of dehumidification by condensation or condensation.
And under microthermal climate, tradition does not have the heat pump drying room of waste heat recovery, because ventilation hydrofuge can cause the new wind of a large amount of low temperature to enter in drying room, considerably increase heat pump and heat load, original heat pump heating at low ambient temperatures newly can just be performed poor, so equal to make the matter worse, energy consumption significantly rises, current existing heat pump dryer utilizes sensible heat exchanger to heat new wind exhaust heat, afterwards by the total heat recovery of evaporimeter to exhaust, although this technology can greatly reduce the waste of heat, but can not heat at outside air temperature lower than there will be heat pump during zero degree or occur frost, the analysis found that, originally deisgn product club under different temperature of outgoing airs cause system occur below different result: 1, if by the air themperature of discharging after two-stage waste heat recovery higher than environment temperature, namely temperature of outgoing air is higher than the temperature sucking new wind, from law of conservation of energy, compressor assembly is in external heat extraction, internal system just obtains the heat of compressor operating power consumption, heating efficiency is extremely low, this Energy Efficiency Ratio with electrothermal tube heating is about the same, heat pump is so adopted to improve heating energy efficiency ratio just without any meaning, come save trouble not as good as directly adopting electrothermal tube heating.If temperature of outgoing air is lower than environment temperature (subzero) after 2, absorbing waste heat by twice again, other problem can be produced like this, the heat exchanger absorbing waste heat exactly can continuous frosting, block air channel soon, due to just serious frosting within very short time can be caused containing large quantity of moisture in exhaust, adopt the Defrost method of general warming machine may not deal with problems.According to above-mentioned analysis, as long as environment temperature is lower than zero degree, because frosting problem causes the heat pump drying room all cisco unity malfunctions being with exhaust heat recovery.So no matter temperature of outgoing air or high or low, all can have a strong impact on the normal work of system.
The application then solves the problems referred to above, performs an analysis respectively below with regard to the utility model in the operation principle in high temperature summer and low temperature winter.
1, summer operation pattern: when keeping dehumidifying coil 5 to work, driven by the speed-changing draught fan of moisture exhausting port 8, when the hydrofuge amount of internal system heat increase moisture exhausting port of more times 8 is just all the more large, the cold and hot balance of indirect regulation heat pump is carried out with the number that this controls hydrofuge amount by speed-changing draught fan 81, namely heat pump occurs that refrigeration does not catch up with when affecting dehumidification by condensation effect with regard to increasing hydrofuge amount, just reduce hydrofuge amount when heat pump heats when not enough drying room temperature does not increase, above-mentioned adjustment can realize automatically controlling by the temperature sensor of the cold and hot end of heat pump.Summer, operating mode was that dehumidification by condensation combines ventilation hydrofuge, the latent heat that ventilation hydrofuge mainly discharges steam carrys out the cold and hot balance of adjusting heat pump system with this, due to the air draft after thermal discharge is analysed in air-flow heat exchange coil 4 heat exchange in opposite directions and new air temperature relatively, its sensible heat of ventilation hydrofuge process does not almost lose, dehumidification by condensation is kept while ventilation hydrofuge, the return air than new wind more low water content can be produced on the one hand, the problem that solution new wind moisture content in summer is higher, the drying efficiency of material can be improved, on the other hand, the operation of dehumidifying cold water can make air-flow in opposite directions remain on duty at air-flow heat exchange coil 4 in opposite directions.
2, winter operation pattern: adopt dehumidification by condensation separately, close moisture exhausting port 8, start the blower fan of outer radiator 6, by drying room and external environment air exchange, like this, also have nothing to do with internal system even if outside air temperature is low again, the change of heat pump and the inner cold and hot amount of drying room just exchanges in various medium in its system, and system unnecessary heat after entering normal dehumidifying normal condition is all externally dispelled the heat with the cold and hot balance of this adjusting heat pump system by the mode of non-Medium Exchange by external radiator.
3, at transition season in spring and autumn, if the heat eliminating medium temperature drift of environment, when relying on separately outer radiator heat-dissipation still can not meet the cold and hot balance of internal system, operational mode reference summer operation pattern is also the cold and hot balance being maintained internal system by the adjustment of the hydrofuge amount of moisture exhausting port 8; If the heat eliminating medium temperature of environment is on the low side, when relying on separately outer radiator just can meet the cold and hot balance of internal system, operational mode reference winter operation pattern.
The above analysis, originally be unfavorable for that traditional condensation dehumidification type heat pump drying room runs summer, be unfavorable for the operation of conventional ventilation dehumidification type heat pump drying room winter, and the design can maximize favourable factors and minimize unfavourable ones under Different climate condition, realize under any weather conditions, remain the operating condition that heat pump drying room is good and energy-conservation.
According to above-mentioned principle, the utility model can also carry out suitable change and amendment to above-mentioned embodiment, such as this drying machine structure can adopt connection tumbler dryer jointly to form design, the air outlet of the air inlet access heat pump dryer of dryer, the air inlet of the exhaust outlet access heat pump dryer of dryer, etc.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.
Through facts have proved, this utility model can be maximized favourable factors and minimized unfavourable ones under Different climate condition, realize under any weather conditions, remaining the operating condition that heat pump drying room is good and energy-conservation, change and be unfavorable for that traditional condensation dehumidification type heat pump drying room runs, is unfavorable for winter the shortcoming of the operation of conventional ventilation dehumidification type heat pump drying room summer in original design, the drying of agricultural product, marine product, Chinese medicine, tobacco, textile etc. can be widely used in.
