Filter be provided for purify air.
Further, above-mentioned precooler 3 and surface cooler 7 are respectively finned copper pipe heat exchanger, the freezing that 7 DEG C of Bottomhole pressure
Water, its input is respectively provided with electric control valve and is used for adjusting chilled-water flow, setting condensation water pond below heat exchange fin, is used for
The condensed water dripping is collected on fin.
Further, separated using aluminium foil between the high temperature channel of above-mentioned board-like sensible heat exchanger 2 and low temperature path.It changes
Hot form is Exchange of apparent heat, and efficiency is up to 60-70%, and fresh air is completely isolated with air draft, it is to avoid form cross-contamination.
Further, separated using grid between the upper channel of above-mentioned rotary type total heat exchanger 6 and lower passage, described
The runner rotating speed of rotary type total heat exchanger 6 is 10-20 rev/min.Rotary type total heat exchanger is with heat storage as material, from
In high-temperature gas, energy absorption is released in cryogenic gas, realizes the energy conversion between gas and gas, and runner covering of the fan passes sequentially through
Top and the cold and hot passage of bottom, complete the transmission of energy.
In the system, fresh air F is sent into the high temperature channel of board-like sensible heat exchanger by the first blower fan, is lowered the temperature as hot blast,
Temperature carries out freeze drying by precooler after reducing again, then cold dry air be passed through again board-like sensible heat exchanger low temperature logical
Road, is heated up as cold wind, and now cold dry air temperature rises, and relative humidity declines；Air after intensification is through the first bypass
Air-valve is mixed with indoor return air R, mixing wind in rotary type total heat exchanger as thermal source through upper channel, heat transfer process is
Constant enthalpy is lowered the temperature, and water capacity rises, and is then passed through surface cooler and carries out freeze drying, the cold dry air of surface cooler output passes through by the of second
Ventilation valve is divided into two-way, a road in rotary type total heat exchanger as low-temperature receiver through lower passage, heat transfer process is constant enthalpy liter
Temperature, air themperature rises, and water capacity declines, and another road connects the outfan of rotary type total heat exchanger lower passage, and table is cold
The air-supply of device outfan is mixed with the air-supply of rotary type total heat exchanger lower passage outfan, and is adjusted by the second bypass air-valve
Whole mixed proportion, finally gives the relatively low air-supply G of water capacity, sends into required place, thus reaching the purpose of accurate dehumidifying.
The water capacity of the air-supply obtaining through the system is lower than the air humidity content after traditional freeze drying, be because through
Rotary-type total heat exchanger, using the mixing wind under specified conditions as thermal source, carries out Total heat exchange, remove more contain wet
Amount.Between rotary type total heat exchanger during positive energy exchange, the temperature difference between the two is by the power conducting heat for two strands of air；With
When relative humidity between difference be also transmission water capacity a power, happens is that constant enthalpy between rotary type total heat exchanger
Process, so water capacity can be delivered in the relatively low Hot wet air heating of relative humidity from the higher cold dry air of relative humidity.
The system through simulation and is tested, and wet the cooling such as is between the first blower fan outfan and precooler input
Journey, completes in board-like sensible heat exchanger, is Exchange of apparent heat；It is freeze drying process in precooler, after precooler, produce
Raw condensed water, air humidity content reduces；Between precooler outfan and board-like sensible heat exchanger low temperature path outfan it is
Wet temperature-rise period, completes in board-like sensible heat exchanger, is Exchange of apparent heat；Board-like sensible heat exchanger low temperature path outfan with
It is air mixed process between rotary type total heat exchanger upper channel input, its mixed proportion can be by the first bypass wind
Valve is adjusted；It is to mix wind through the process of rotary type total heat exchanger in rotary type total heat exchanger upper channel, be
Constant-enthalpy process, temperature drop, water capacity rises；It is freeze drying process in surface cooler, is completed by surface cooler, be dehumidifying and cooling mistake
Journey；It is the constant enthalpy temperature-rise period through rotary type total heat exchanger in rotary type total heat exchanger lower passage, temperature rises,
Water capacity reduces.Ventilation state point temperature after the system final process is 16.2 DEG C, humidity is 58%RH, air humidity content
For 6.6g/kg, the air humidity content dehumidifying with respect to general freezer（23.2℃、66.1%RH、11.76g/kg）Much lower.
As shown in Fig. 2 fresh air F of the respectively first blower fan input, precooler input A, precooler outfan B, plate
Formula sensible heat exchanger low temperature path outfan C, rotary type total heat exchanger upper channel input M, the second blower fan input
Return air R, surface cooler input D, surface cooler outfan E, rotary type total heat exchanger lower passage outfan air-supply G wet in enthalpy
The expression of in figure.
Following table is the Comparative result that the system is dehumidified with traditional air conditioner and controls for different operating modes：
Can be seen according to upper table, the system, under the standard condition of simulation, is compared traditional air-conditioning system, had larger excellent
Gesture.The system is applied to the special occasions that required precision is higher or requirement air-supply water capacity is relatively low to air-supply water capacity, such as cures
The fields such as institute, biochemical laboratory, high standard storage room, tobacco warehouse, food/pharmacy；Using fresh air itself as regulation medium
And thermal source, stage by stage as the thermal source of heating and regeneration；Using the difference of the relative water capacity of fresh air as the power of dehumidifying；Using
Board-like sensible heat exchanger, as preheating device, by the use of the temperature difference before and after surface cooler as power, reduces the relative humidity of fresh air；Adopt
With rotary type total heat exchanger as dehydrating unit, wet as changing by the use of the difference between the relative humidity of runner upper and lower both sides air
Power, formed height water capacity between reverse transmission, reach depth dehumidifying effect；Rotary type total heat exchanger it
Before, setting bypass air-valve, can by automatic control and manual by way of adjust aperture, make through with without dehumidifying fresh air with appoint
Anticipate mixing accurate in scale, for adjusting the water capacity of final air-supply；The dehumidifying of the system depth is to adopt rotary type total heat exchanger
Come to realize, the thermal source of secondary dehumidifying comes from the air-supply of high temperature low humidity itself；The precise control of humidity passes through the air-valve that links, and comes
Control and pass through and to realize without the mixed proportion of the air of depth dehumidifying, the air-supply of any number between two kinds of water capacities
State, all can be reached by mixed wind ratio.
The system is different from air conditioner dehumidification technology traditional at present, the medium being dehumidified as depth using fresh air itself, profit
With traditional low-temperature receiver as preliminary dehumidification mode, the core component being dehumidified as depth by the use of rotary type total heat exchanger carries out secondary
Dehumidifying, is supplied to secondary deep dehumidifying using the change of the relative humidity of fresh air as power；The system does not have air draft in itself, permissible
Freely adjust fresh air and return air ratio, compact conformation, modern design, reach the purpose of depth dehumidifying and humidity precise control.
