Detailed description of the invention
As it is shown in figure 1, the double low-temperature receiver dehumidification system of described constant temperature and humidity capillary tube air conditioner fresh air, including prime
Dehumidifying part and rear class dehumidifying part two-stage degree of depth Dehumidifying element, described prime dehumidification portion is divided and is included new wind
The roughing efficiency air filter 1 that carries out successively processing, electric purification filter 2, runner heat reclamation device 3, table
Cooler 5, compressor 6, described rear class dehumidification portion divides and includes homoiothermic and standby coil pipe 8, wet-membrane humidifier 7,
Described system also includes that the switch board 4 being controlled, described surface cooler 5 include Surface cooling coil 51 and steam
Feel cold condenser 52.
System also includes indoor return air exhaust system so that indoor return air is returned through primarily efficient filter, runner heat
Receiving heel row the most outdoor, described indoor return air exhaust system includes indoor return air entrance 23, return air pressure fan
15, the second roughing efficiency air filter 25, runner heat reclamation device 3, outdoor exhaust blower 14, outdoor exhaust outlet
22, described indoor return air exhaust system and prime dehumidifying partial common same runner heat reclamation device 3.
Described system includes new wind entrance 21 and coupled new wind pressure fan 13, and then new wind enters
Entering prime dehumidifying part, described system is divided into upper and lower two layer box bodies, described prime dehumidifying part to be positioned at lower floor
Casing, described rear class dehumidifying part is positioned at layer box body, between upper layer box body and lower layer box body, arranges
There are system exhaust blower 11, system pressure fan 12, for forwarding new wind to upper layer box body.
In prime dehumidifying part, new wind is through primarily efficient filter, electric purification filter 2, runner recuperation of heat
Cooling process is carried out by surface cooler 5, it is contemplated that the fluctuating factor that chilled water is possible, described table after pretreatment
Cooler 5 is designed as 8 rows, for preferably utilizing the cold concentrating low-temperature receiver, design summer air temperature by
12 DEG C/95% design.
In view of making full use of concentration low-temperature receiver, degree of depth dehumidification portion sets up separately and is calculated as front and back stages dehumidifying part.Root
It is automatically adjusted the quantity put into operation according to the chilled water supply water temperature concentrating low-temperature receiver to provide.Carrying out practically is thought
Road is as follows:
1) when chilled water supply water temperature relatively low (generally below 10 DEG C), Surface cooling coil 51 can be by
Fresh air handing to less than 14 DEG C, now the leaving air temp of surface cooler 5 is automatic by water valve regulation desired value
It is set as 14 DEG C of air-out；Unlatching level deep dehumidify, air absolute moisture content is processed 8.5g/kg with
Under (dew point less than 12 DEG C), and by the condensation heat of compressor, wind pushing temperature is reheated to about 18 DEG C
The most directly send (the most standby homoiothermic and standby coil pipe 8 need not run)；
2) when chilled water supply water temperature higher (generally greater than 10 DEG C), Surface cooling coil 51 cannot be straight
Connect below Fresh air handing to 14 DEG C, but 12 DEG C are supplied water or can be by below Fresh air handing to 16 DEG C.
Now the leaving air temp of surface cooler 5 is automatically made 16 DEG C of air-out by water valve regulation desired value；Open
The two-stage degree of depth dehumidifies, and air absolute moisture content processes below 8.5g/kg (dew point less than 12 DEG C),
And by the condensation heat of compressor 6, wind pushing temperature is reheated to about 25 DEG C, then by standby homoiothermic
And wind pushing temperature is adjusted to less than 20 DEG C air-supplies by standby coil pipe 8.
One-level vaporizer that described evaporative condenser 52 includes being sequentially connected with, secondary evaporimeter, two grades cold
Condenser, first-stage condenser, described one-level vaporizer is connected with Surface cooling coil 51, in step 1) in
Level deep dehumidifying only need to open one-level vaporizer and first-stage condenser, and in step 2) in two-stage
Then it is all turned on during degree of depth dehumidifying.
New wind is sent into upper layer box body by system pressure fan 12, then delivers to room after medium effeciency filter filters
Rear class dehumidify part, be step 2) in the two-stage degree of depth dehumidifying time use, the tune of upper layer box body
Warm and standby coil pipe 8 is in holding state summer, if wind pushing temperature higher than 20 DEG C time automatically turn on into
Row regulation；During two-stage degree of depth dehumidifying all report faults, fully open input maximum capacity of opening dehumidifies.Winter this
Coil pipe completely closes, and heats with crossing Surface cooling coil 51.
And open under wet-membrane humidifier 7 heated condition the most in the winter time, humidify for winter.Open amount according to
The parameter of indoor humidity feedback is adjusted.The outside of described indoor blower 9 is provided with temperature and humidity sensing
Device 91, described Temperature Humidity Sensor 91 feeds back for wet-membrane humidifier 7.New after treated satisfied requirement
Wind is sent into indoor by indoor air outlet 24.
Further, at surface cooler 5, it is provided with temperature sensor 53, sets at return air pressure fan 15
It is equipped with Temperature Humidity Sensor 92.
Additionally, sending in described system, exhaust blower all uses VFC.When refrigerating operaton, need
Constant wind quantity runs (if needing variable air volume running, it is proposed that at more than the 80% of total blast volume).Conditioning in Transition Season
Save or variable air volume running can be realized by actual demand winter.
Further, unit is provided with between runner heat reclamation device 3 and Surface cooling coil 51 and once returns
Air port 10, it is possible to achieve the new wind+return air operational mode of part.
Native system is controlled by robot control system(RCS), and the control of all devices is integrated in one by robot control system(RCS)
In switch board 4, switch board 4 is arranged on unit by damascene structures.
