Description

A kind of air open-circuit circulating heat pump clothing-drying wardrobe
Technical field
The present invention relates to drying device design field, particularly relate to a kind of air open-circuit circulating heat pump clothing-drying wardrobe.
Background technology
Heat pump, as a kind of handbarrow of heat, improve tow taste heat quality in soil, air, water to obtain the equipment compared with high-grade heat, under the background of energy-saving and emission-reduction as a kind of, in fields such as heating, hot water, dryings, obtain and apply more and more widely.The essence of heat pump energy-conserving is exactly inject a small amount of electric energy to drive compressor, is operated by the suction and discharge of compressor, will absorb the low pressure refrigerant gas of a large amount of tow taste heat in evaporimeter, is compressed into gases at high pressure and enters condenser and realize high-temperature position heat release.
Usually, the ratio of the electrical power that the heat pump condenser heat release power determined under operating mode and compressor suck, the Energy Efficiency Ratio of heat pump is called.Under standard condition, this Energy Efficiency Ratio is generally near 4, the namely electrical power input of water 1kw, the high-temperature position that the tow taste heat of about 3kw in soil, air, water is transported to required for people can be gone, carry out operations such as heating, dry, and obtain the heating power of about the total amount 4kw be made up of tow taste heat and compressor horsepower in high-temperature position.
The characteristics of energy saving of heat pump, makes it, in heating, hot water, drying etc. field, to obtain a wide range of applications.Wherein, containing the drying of wet stock, needing flood tide heat, is big power consumer.When will carry out heat drying containing wet stock, after drying operation, create a large amount of low-grade heat humid air, if heat pump techniques can be used to carry out these low-grade heat humid air, and heat is wet to be reclaimed, both flood tide energy had been saved, additionally reduce the pollution of Hot wet air heating to environment, there is important economic worth and Significance for Environment.
When containing wet stock by heat drying, at commitment and the constant rate drying period of drying, the heat needed for material moisture evaporation is completely from dry air, and the surface temperature of material equals the wet-bulb temperature of air.Namely also the evaporation rate of material surface unbound water is very high for rate of drying now, and has nothing to do with the character of material and moisture, only depends on the structure of drier and the flow velocity of dry air; Dry moisture of vaporizing is all unbound water.At constant rate drying period, dry air does " constant enthalpy " change, and the enthalpy (energy density) of air is constant, but drying air temperature fall is large, relative humidity and absolute moisture content increase fast, the sensible heat of dry air is transformed to the latent heat of water vapour, and the humidity load of air increases fast.After completing drying process, carry the damp-heat air of a large amount of humidity load (water vapour), if directly enter environment, will a large amount of wastes of the energy be caused.
For heat pump clothes dryer, existing heat pump clothes dryer, mostly adopts air closed cycle mode.When air closed cycle heat pump clothes dryer is used for step wet clothes drying operation, also namely wet clothes successively by " cage one cage " (intermittently) be placed on heat pump condenser after dry air in carry out drying time, air is heated into the dry air of high-temperature, low humidity through condenser, flows through wet clothes and carries out drying operation; At commitment and the constant rate drying period of dry run, dry air does " constant enthalpy " change, the enthalpy (energy density) of air is constant, but drying air temperature declines to a great extent, relative humidity and absolute moisture content increase fast, the sensible heat of dry air is transformed to the latent heat of water vapour, and the humidity load of air increases fast.After completing drying process, carry the damp-heat air of a large amount of humidity load (water vapour), flow to evaporator with heat pump, heat release cooling in evaporimeter, when damp-heat air temperature drops to below corresponding humid air dew-point temperature, the water vapour in air on an evaporator exothermic condensation is separated out.Separate out the saturated air of part water vapour through evaporator, be again heated into the dry air of high-temperature, low humidity through condenser, enter next dry cycle.
But at falling rate drying period, wet clothes has lost most moisture, close to " oven dry " state; At falling rate drying period, air closed cycle in heat pump clothes dryer, " constant enthalpy " change is still done when high-temperature after condenser heating, low humidity dry air flow through clothing, the enthalpy (energy density) of air is constant, but the increasing degree of the fall of the temperature after falling rate drying period dry air flows through clothing, relative humidity and absolute moisture content is compared with constant rate drying period, all occurs obviously narrowing; After completing the drying operation to clothing, the decline of drying air temperature is few, the amplification of moisture content (water vapour) is little, and the corresponding dew-point temperature of dry air is lower; Dry air flows to evaporator with heat pump and heat release cooling in evaporimeter, but temperature is difficult to drop to below corresponding dew-point temperature, although the relative humidity of air increases to some extent but can not reach " saturated " state after cooling, water vapor in air is difficult to exothermic condensation on an evaporator and separates out; Lower the temperature through evaporator but there is no the unsaturated air that water vapour exothermic condensation is separated out, the device that is again condensed is heated into high-temperature, the dry air of low humidity carries out closed cycle, invalid operation under " high temperature " state, seriously reduces the heat pump drying effect of falling rate drying period and raises the bulk temperature level of closed cycle air continuously.
Although the moisture great majority in " wet clothes " of falling rate drying period evaporate, close to " drying ", also do not have bone dry, dry task does not also finally complete.If there is no water vapour exothermic condensation precipitation on an evaporator, just really do not complete the desiccant dehumidification of falling rate drying period, just do not solve " last one kilometer " problem of wet clothes drying; High temperature air proceeds closed cycle, the just lasting invalid operation of heat pump under " high temperature " state.

The operation principle of this air open-circuit circulating heat pump clothing-drying wardrobe is specific as follows:
One, the periodic duty principle of cold-producing medium
High temperature refrigerant gas after compressor 8 out pressurized, flows through the pipeline of condenser 6, realizes heat release cooling, transfers heat to the air flowing through condenser 6, and the refrigerant liquid that high temperature refrigerant condensation of gas is liquefied as low temperature simultaneously exports; The refrigerant liquid of low temperature, after throttling arrangement 9 reduces pressure, is imported in the pipeline of evaporimeter 12, and absorb after flowing through the heat of the air of evaporimeter 12, evaporation becomes low pressure refrigerant gas; Compressor 8 flows to condenser 6 after pressurizeing to the low pressure refrigerant gas of being come by evaporimeter 12 again, thus forms a complete refrigerant circulation.
Two, dehumidification principle
The external environment air of drying machine is sucked by the first blower fan 7, is heated into dry air through condenser 6; The ventilating opening 301 of dry air on dividing plate 3 enters in drying room 1, flows through and carries out drying operation containing wet stock; With carry out after hot and humid area completes drying operation containing wet stock, dry air is transformed into damp-heat air; Damp-heat air flows to evaporimeter 12 by drying room top outlet inlet 102, moisture passages 101 successively, heat release cooling in evaporimeter 12, and the exothermic condensation on evaporimeter 12 of the water vapour simultaneously in air is separated out; Separate out the air after most of water vapor through evaporator 12, more directly discharged drying machine by air-out passage 5.
With reference to Fig. 3, be constant rate drying period in early days in dry run, humidity load is higher.The external environment air of drying machine is heated into the dry air of high-temperature, low humidity through condenser 6, the wet stock that contains that dry air is higher to moisture content carries out drying operation; At this constant rate drying period, dry air does " constant enthalpy " change, and the enthalpy (energy density) of air is constant, but drying air temperature declines to a great extent, relative humidity and absolute moisture content increase fast, the sensible heat of dry air is transformed to the latent heat of water vapour, and the humidity load of air increases fast.With carry out after hot and humid area completes drying operation containing wet stock, damp-heat air is heat release cooling in evaporimeter 12, and when damp-heat air temperature drops to below corresponding dew-point temperature, the exothermic condensation on evaporimeter 12 of the water vapour in air is separated out; Separated out the saturated air of most of water vapor through evaporator 12, temperature and water capacity all greatly reduce, and enthalpy greatly reduces, then are excluded drying machine.
With reference to Fig. 4, the phase is falling rate drying period after drying process, and humidity load is lower.Air in the external environment of drying machine is inhaled into, and is heated into the dry air of high-temperature, low humidity through condenser 6; What through ventilating opening 301, dry air flow through that moisture content significantly reduced carries out drying operation containing wet stock, now dry air still does " constant enthalpy " change, the enthalpy (energy density) of air is constant, but dry air flow through containing wet stock after the fall of temperature, the relative humidity constant rate drying period early stage with drying with the increasing degree of absolute moisture content compared with, all occur obviously narrowing, the fall of drying air temperature amplification that is little, moisture content (water vapour) is little; Air after drying operation flows through pump evaporimeter and heat release cooling in evaporimeter, and temperature is difficult to drop to below corresponding dew-point temperature, although the relative humidity of air increases to some extent but water vapor in air to be difficult on evaporimeter 12 exothermic condensation precipitation; Through the unsaturated air that evaporator 12 is lowered the temperature, its absolute moisture content, still higher than the air in machine external environment, is directly discharged among drying machine external environment.
Although the moisture great majority in " wet clothes " of falling rate drying period evaporate, close to " drying ", also do not have bone dry, dry task does not also finally complete.At falling rate drying period, the high temperature air in traditional air closed cycle heat pump clothes dryer proceeds closed cycle, the just lasting invalid operation of heat pump under " high temperature " state; Do not have water vapour exothermic condensation on evaporimeter 12 to separate out, just do not complete last desiccant dehumidification, just do not solve " last one kilometer " problem of wet clothes drying.And at falling rate drying period, a kind of air open-circuit circulating heat pump clothing-drying wardrobe provided by the invention, the absolute moisture content of the surrounding air that the absolute moisture content of the air outlet air of air-out passage 5 sucks higher than the air inlet of air intake passage 4, the difference of these two absolute moisture contents is exactly the drying capacity of falling rate drying period heat pump.This ability, can solve the last desiccant dehumidification problem containing wet stock drying close to " oven dry " state that " moisture content " has significantly reduced.
