Description
Technical field
The utility model relates to the large temperature difference heat pump dehumidifier of a kind of high temperature, is mainly used in the dehumidifying in high temperature place, the dehumidifying of drying the hot and humid gas in place and oven dry.
Background technology
Current existing heat pump dehumidifier, owing to being compressed the restriction of machine back pressure, the environment temperature of the highest adaptation of dehumidifier of normal domestic is generally no more than 40 DEG C, and gas only has about 5 DEG C by the temperature difference that evaporator temperature declines; The highest temperature that conforms of industrial heat pump dehumidifier is generally no more than 55 DEG C, and the temperature difference that gas is declined by evaporator temperature is at about 10 DEG C; Thermal pump dehumidification drying all-in-one, owing to having set up heat exchange core body, the highest temperature that conforms generally has been no more than 65 DEG C, and the total temperature difference that gas is declined by evaporimeter and heat exchange core body temperature is generally within 20 DEG C.
Because the ability of Air containment water vapour improves along with the raising of temperature, so the dehumidifying effect of heat-pump dehumidification improves along with the increase of the raising of temperature, the temperature difference of cooling.
Dehumidifying effect refers to the dewatered quality g of humid air often processing 1kg dry air, that is:
The water capacity (all when pressure is 101325pa) of saturation state humid air at temperature after the water capacity-cooling of the front humid air of dehumidifying effect=cooling.
Such as, when relative humidity is all 80%:
The dehumidifying effect that normal domestic dehumidifier drops to 30 DEG C temperature 35 DEG C is 36.756*0.8-27.329=2.08g/kg; The dehumidifying effect that industrial heat pump dehumidifier drops to 40 DEG C at temperature 50 C is 86.856*0.8-49.141=20.34g/kg; The dehumidifying effect that thermal pump dehumidification drying all-in-one drops to 40 DEG C at temperature 60 C is 153.54*0.8-49.141=73.69g/kg.
Above several dehumidifiers all can not be applied in temperature higher than the place of 65 DEG C, and dehumidifying effect is not high.
Thermal pump dehumidification drying all-in-one is applied in the dehumidifying of the hot and humid gas of drying place, because the maximum cooling temperature difference of dehumidifying only has 20 DEG C, this temperature difference be less than dry environment temperature outside the gas temperature in place and place the temperature difference (such as, gas temperature 60 DEG C, environment temperature 20 DEG C, the temperature difference 40 DEG C), so the dehumidifying effect of thermal pump dehumidification drying all-in-one is lower than directly the dehumidifying effect that hot and humid gas discharging falls.In oven dry is produced, in order to improve the operating efficiency of oven dry, need at interval of a period of time, hot and humid gas in oven dry place is directly emitted, again the air heat under the environment temperature outside the oven dry place of equivalent to dry need temperature on, and be sent to oven dry place, thus waste a large amount of energy.

Specific implementation process:
The large temperature difference heat pump dehumidifier of a kind of high temperature, comprise air total heat recovery device 9, left air channel shell 4 and right air channel shell 11 is provided with in the left and right sides of air total heat recovery device 9,15 are exported after air total heat recovery device 9 is provided with recover upper left, lower air duct shell 5 on the arranged outside exporting 15 behind recover upper left has, upper lower air duct shell 5 with export 15 behind recover upper left, left air channel shell 4 is communicated with; Compressor assembly (comprising fluid reservoir, gas-liquid separator, expansion valve) 13 is arranged on position between left air channel shell 4, right air channel shell 11, and is fixed on chassis 14; Air total heat recovery device 9 is fixed on left air channel shell 4, right air channel shell 11, upper lower air duct shell 5 by recover and air channel shell set bolt 7, and electric cabinet 8 is fixed on the side plate of air total heat recovery device 9.
In left air channel shell 4, be provided with condenser (heat exchanger of refrigerant and air) 3, air-introduced machine 2, the air outlet of air-introduced machine 2 is high temperature dry air outlets 1; The delivery pipe 12 of evaporimeter (heat exchanger of refrigerant and air) 10, condensed water is provided with in right air channel shell 11.
Refrigerant pipeline and the condenser heat exchanger of air (refrigerant with) 3, the evaporimeter heat exchanger of air (refrigerant with) 10, compressor assembly (comprising fluid reservoir, gas-liquid separator, expansion valve) 13 are communicated with and form closed loop, complete the overall process of condensation, evaporation in the condenser 3 of refrigerant in left air channel shell 4, right air channel shell 11, evaporimeter 10.
Dry the hot and humid air in place to enter recover 9 from entrance 6 before the upper left of recover and carry out heat exchange with the air of low temperature and low humidity, through cool-down dehumidification, be discharged in right air channel shell 11 by exporting 17 behind the bottom right of recover again, then carry out cool-down dehumidification again through evaporimeter (heat exchanger of refrigerant and air) 10, now complete the overall process of dehumidifying.In air total heat recovery device 9, condensed water is by exporting the bottom that 17 are discharged to right air channel shell 11 behind recover bottom right, the condensed water of evaporimeter (heat exchanger of refrigerant and air) 10 also flows to the bottom of right air channel shell 11, is then together discharged outside machine by drip pipe 12.Now air has become the air of low temperature and low humidity, the air of low temperature and low humidity again before the bottom right of recover entrance 16 enter in air total heat recovery device 9 with dry the hot and humid air sent in place and carry out heat exchange, define time high temperature dry air, secondary high temperature dry air enters in upper lower air duct shell 5 by exporting 15 discharges behind the upper left of recover, enter in left air channel shell 4 again, then by after the temperature of the further lift gas of condenser (heat exchanger of refrigerant and air) 3, define high temperature dry air, high temperature dry air finally exports 1 by high temperature dry air through air-introduced machine 2 and discharges, dry used for object for drying place.
Such as (see figure 4):
Dry 75 DEG C, place, the air (relative humidity 80%) of water capacity 309.13g/kg, enters air total heat recovery device 9 by entrance 6 before recover upper left, and with wherein 10 DEG C, the gas of water capacity 7.66g/kg carries out heat exchange.
Because the gas water capacity of 75 DEG C of sides is large, namely heat enthalpy value is high, and in the middle of heat exchange, for the gas of equal in quality, what the gas temperature of 75 DEG C of sides declined has a narrow range of temperature, and the temperature difference that the gas temperature of 10 DEG C of sides rises is large.
Just can determine heat exchange area and the model of air total heat recovery device according to heat exchange amount and heat transfer temperature difference, make 75 DEG C of side air drop to 20 DEG C behind recover bottom right, export 17 discharges; The air of 10 DEG C of sides rises to 70 DEG C and behind recover upper left, exports 15 and discharges.
Behind recover bottom right, export 17 air of 20 DEG C of discharging enter evaporimeter (heat exchanger of refrigerant and air) 10, temperature drops to 10 DEG C and enters into entrance 16 before recover bottom right again; The 70 DEG C of air exporting 15 discharges behind recover upper left enter condenser (heat exchanger of refrigerant and air) 3 and promote temperature.
Because gas has condensed water to separate out the release latent heat of vaporization in evaporimeter, compressor power consumption discharges heat energy within the condenser in addition, so the temperature difference that the gas of equal in quality heats up within the condenser is greater than the temperature difference of lowering the temperature in evaporimeter.Can determine the input power of heat pump according to the size of ventilation volume, make the air themperature of 70 DEG C rise on 85 DEG C, now, the water capacity of the air of 85 DEG C only has 7.66g/kg.
