Description
Technical field
The utility model relates to clothing-drying wardrobe design field, particularly relates to the heat pump clothes-drying cabinet that a kind of dehumidification system side arranges, has the dehumidifying of the low condensing pressure deeply undercooling degree of depth.
Background technology
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.
Existing heat pump clothes dryer is mostly on roller washing machine basis, installs heat-pump-type heating additional and forms with dehumidification equipment; 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 existing heat pump drying and refrigerated dehumidification technology, also exist following problem:
1, condenser ventilation is less than normal, and condensing pressure is raised, and causes that the power consumption of compressor increases, pressure reduction increases, compression ratio increases, Energy Efficiency Ratio reduces
Refrigerant dehumidification system of the prior art operationally, the condensation thermal discharge of high-temperature high-pressure refrigerant gas in condenser, the sensible heat Q1 that to be refrigerant gas release from humid air during the cool-down dehumidification that evaporimeter brings, humid air, water vapour condensation heat Q2 and compressor are to the summation of the work done during compression A three of low pressure refrigerant gas, are generally about 3 times of the sensible heat Q1 that the humid air cooling of vaporizer side is released.And the condenser of refrigerant dehumidification system, evaporimeter are in same air channel, share a blower fan, adopt series system to ventilate; In order to evaporimeter can dehumidify by effective temperature-reducing to suction air under the dew-point temperature of air, the ventilation of blower fan just can not be too large; And meet the ventilation of evaporimeter cool-down dehumidification, for less than normal again condenser; The air themperature flowing through condenser is caused to rise excessive, drive condenser condenses temperature to raise, namely condensing pressure is raised, and causes the pressure reduction of refrigerant dehumidification system condensing pressure and evaporating pressure to increase, the power consumption of compressor increases, compression ratio increases, and Energy Efficiency Ratio reduces.
The leaving air temp of the conventional heat pump drying system (or refrigerant dehumidification system) of evaporator-condenser air channel series connection, can derive on humid air psychrometric chart.
With reference to figure 9, suppose that air condition that the refrigerated dehumidification device of connecting in evaporator-condenser air channel sucks corresponds to a point on air psychrometric chart, namely suck the temperature of air, humidity, enthalpy be respectively 40 DEG C, 40%RH, 89KJ/ (kg dry air); From a point, 40 DEG C, 40%RH, 89kJ/ (kg dry air) containing humid air, flow through evaporimeter and be cooled to 24 DEG C, the b point of 100%RH, 72kJ/ (kg dry air), namely become saturated air; Saturated air is lowered the temperature further in evaporimeter, namely water vapour exothermic condensation is had to separate out, the temperature humidity enthalpy going out air during evaporimeter becomes 21 DEG C of c point, 100%RH, 62kJ/ (kg dry air) respectively, realizes dehumidifying 3.3g/ (kg dry air); In the process of a → b → c, humid air enthalpy change (enthalpy difference) is 27kJ/ (kg dry air); This 27kJ/ (kg dry air) enthalpy of humid air difference (heat) is absorbed by evaporimeter, is converted into the heat of vaporization of cold-producing medium, then is transported in condenser by compressor and discharges; Only condenser discharges the enthalpy difference (heat) of this part, and namely c point air is condensed device heat drying to c ' point, and namely air condition is changed to 48.3 DEG C, the c ' point of 22%RH, 89kJ/ (kg dry air) from c point; And condenser heat rejection amount is evaporimeter caloric receptivity and compressor compresses merit sum, so add the work done during compression of compressor, the state flowing through the air of condenser namely from 48.3 DEG C, the c ' point of 22%RH, 89kJ/ (kg dry air) rises to 56 DEG C, the c of 15%RH, 97kJ/ (kg dry air) further " point.The leaving air temp of condenser reaches 56 DEG C, is higher than leaving air temp, up to about 60 DEG C for realizing the condensation temperature of condenser to the cold-producing medium in air exothermic condensation device.
If the refrigerant evaporating temperature reduced further in evaporimeter dehumidifies with the degree of depth realized containing humid air, such as on psychrometric chart from a point, by a point 40 DEG C, 40%RH, 89kJ/ (kg dry air) containing humid air, flow through evaporimeter cool-down dehumidification to 15.2 DEG C, the e point of 100%RH, 43kJ/ (kg dry air), then the temperature of the air-out of condenser, humidity, enthalpy will reach 70 DEG C, 5.5%RH, 99kJ/ (kg dry air) respectively, and the condensation temperature of the cold-producing medium in condenser will reach about 75 DEG C.
The condensing pressure of such refrigerant dehumidification system and the pressure reduction of evaporating pressure are too large, and the power consumption of compressor is too large, compression ratio is too high, and Energy Efficiency Ratio is too low, and such operating mode is unsafe!

Existing heat pump drier, refrigerated dehumidification machine adopt monoblock type condenser, attempt in a monoblock type condenser, complete continuously the heat release cooling of sensible heat part of superheated refrigerant gas that compressor discharges, the condensation heat release liquefaction of refrigerant gas and refrigerant liquid further cooling excessively cold.
In fact, material selected by monoblock type condenser is all copper, the good conductor of the heat such as aluminium, thus in " the heat release cooling of superheated refrigerant gas sensible heat part ", " heat bridge " is formed along fin direction between the region that " refrigerant gas condensation heat release liquefaction " and " refrigerant liquid was lowered the temperature cold further " these three have an obvious temperature fall, cause heat from " the heat release cooling of superheated refrigerant gas sensible heat part ", " refrigerant gas condensation heat release liquefaction " region is transmitted along fin to " refrigerant liquid was lowered the temperature cold " region, seriously undermine " excessively cold " degree of condenser ends refrigerant liquid.
Due to not enough at condenser ends refrigerant liquid " excessively cold ", refrigerant liquid temperature exceeds a lot than the refrigerant evaporating temperature in evaporimeter, and first refrigerant liquid will be reduced to evaporating temperature own temperature carry out evaporation endothermic in evaporimeter before, for this reason, choke valve (capillary) before entering evaporimeter is inner, there is again a small amount of liquid refrigerant and do not enter evaporimeter with regard to shifting to an earlier date carburation by evaporation, absorb the sensible heat of most liquid refrigerant to promote that its " excessively cold " is to evaporating temperature.And a small amount of liquid refrigerant does not enter evaporimeter just shift to an earlier date carburation by evaporation in capillary, this causes again the evaporation endothermic ability of evaporimeter to comprise the decline of dehumidifying effect further.
3, arid region, air is uniformly distributed the problems such as Uniform Flow
Many enterprises and research staff, attempt to arrange steam compression type refrigeration dehumidification system on wardrobe, makes wardrobe while storage clothing, have the function utilizing heat pump to realize refrigerated dehumidification, drying clothes concurrently.
But, for heat pump type clothes dryer, how to solve in the principal space region of wardrobe i.e. arid region, air is uniformly distributed Uniform Flow problem, namely the dry air how making refrigerated dehumidification equipment room export flow uniformly through wardrobe horizontal section, effectively carry out heat exchange, do not stay the problem at dead angle with wet clothes, never solve very well.
Further, how to solve the line come off from clothing in dry run and consider to be worth doing, in cyclic process, be attached to the air inlet of evaporimeter, condenser, to the blockage problem that the fin clearance of refrigerant dehumidification system evaporimeter, condenser produces; How to solve the condensed water that refrigerant dehumidification system evaporimeter is separated out humid air cool-down dehumidification, utilize the natural emission problem of spatial altitude difference; These problems also never have effective solution.
